The Printed Circuit Board, or PCB, has revolutionized the electronics industry. Invented in the 1930s, it has come to be used in every imaginable electronic gadget. This article explains the importance of these boards, and examines their benefits and manufacturing options.

Why Use A PCB? What Can It Be Used For?

Before delving into the details, it’s important for you to know the possible applications of Printed circuit boards, and why you should use them (i.e., what their advantages are).

What can you use them for? Absolutely everything! There’s virtually no electronic device that can’t be built using PCBs. Battery-operated toys, cell phones, music players, TVs, computers, automobiles, aircraft – almost everything that uses some sort of electronics, makes use of them.

Whether you’re a hobbyist building a toy, a student doing science-project, or an appliance-maker manufacturing millions of devices, the use of printed boards offer benefits.

Firstly, a PCB is much smaller than other types of circuits. Its reduced size is an extremely important aspect to its overall production process. In addition, a printed circuit greatly reduces the need for wires. This improves the appearance of the final circuit and enhances durability. For mass-producers ordering in large production, it’s the cheapest method, offering huge cost benefits.

What are the Key Design Considerations when making a PCB?

There Are Three Main Elements:

* A laminate board.
* The components mounted on the board.
* Traces that serve as the “wires” connecting components and forming the circuit.

The actual components used depend entirely on the purpose of circuit. Examining which components to use is best dealt in an encyclopedia series. This leaves laminate boards and traces. Production costs, working efficiency and operating cost of the finished circuit, all depend on these elements.

Of the several materials used for the boards, six are the most widely manufactured: FR-1, FR-2, FR-3, FR-4, CEM-1 and CEM-3. “FR” stands for “flame retardant”. FR 1, 2 and 3 are essentially the same, with only minor differences in properties. They are not suited for building multilayer boards. The same is true for CEM-1.

FR-4 and CEM-3 are two laminates that can be used for multilayer boards. Of the two, FR-4 is more widely manufactured, and hence is cheaper. It can be used for single and multilayer boards, and has excellent thermal tolerance up to 130°C.

Copper is the most commonly used material for traces. Simple methods involve plating the entire board with copper, and then etching away unnecessary areas through a mask (stencil) to leave the required traces. More complex methods allow traces to be added on to a bare board. Each approach has associated pros and cons.

Some boards require the use of gold for sensitive, low-voltage applications or lead-free (RoHS) compliance. Copper traces usually demand the use of a nickel barrier layer before gold-plating. This is to prevent gold from migrating into the copper. Indiscriminate use of nickel can result in huge losses to impedance.

If you want to develop a custom PCB, it’s recommended that you first spend a little time understanding the basics of PCB design. There are several detailed guides and tutorials. Also, design and simulation software are available to help you test your design before you make a PCB Prototype.

Paul Eisle invented the first PCB in 1936. However, it became popular only in the 1950s when the US military started using the technology in bomb detonators. Today, PCB Circuit Boards are an integral part of almost all equipment, like cars, mobile phones, computers and more.  

How Is A Printed Circuit Board Manufactured?

To make a custom PCB, first the electronic diagram of the required circuit is prepared using Computer Aided Design (CAD) software. After that the PCB prototype is developed using Computer Aided Manufacturing Software technology.

The common materials used for manufacturing PCBs are: FR4, FR4 High Temperature, Polyimide, GeTek, Rogers, Arlon, Nelco, Alumina, Ceramic, Bakelite, FR1, CEM1, and CEM5. The size and thickness of the board depends upon the requirements of the circuit. The substrate is coated with a layer of copper. Then, using photosensitive coating, the circuit diagram is printed on the board. The undesired copper is etched out from the board to form copper “tracks”, called traces. This process is known as Photoengraving. There are two other common methods used for developing connecting traces. PCB milling is a mechanical system where undesired copper is removed with CNC machines. Another process is Silk-Screen printing, where special ink that is etch-resistant is used to cover the areas where the copper traces have to be made.

Once the board is ready with copper traces, holes are drilled into the board to assemble leaded electrical and electronic components. For drilling, special Tungsten Carbide drill bits or laser is used. The holes made are filled with hollow rivets or coated through using an electroplating process, thus forming an electrical connection among the various layers. The next step is coating of the entire board, except holes and pads, with masking material. Materials commonly used for this purpose are: lead solder, lead free solder, OSP (Entek), deep/hard gold (electrolytic nickel gold), immersion gold (electroless nickel gold – ENIG), wire bondable gold (99.99% pure gold), immersion silver,   
flash gold, immersion tin (white tin), carbon ink, and SN 100CL, an alloy of tin, copper, and nickel. The last step is screen-printing, where the legend and text are printed on the PCB.

Testing Of PCB

Before assembly of components or delivery of Printed Circuit Boards, the board should be tested to find any possible “shorts” and “opens” that could lead to a non-functioning board. A “short” indicates the existence of an undesired connection and an “open” indicates that two points that should have been connected are unconnected. All such errors should be fixed before PCB assembly. It is important to note that not all PCB Manufacturing shops test the boards before shipping, it is sometimes considered an added cost but a vital one to provide a fully functioning board before adding components.

PCB Assembly

Once the board is ready, components are assembled and added to the surface as per the circuit diagram. Some of the common assembly techniques used are surface-mount construction and through-hole construction. Sometimes, a combination of these two techniques is also used for assembly. 

Types of Printed Circuit Boards

Single Sided Board

This is the least complex of the Printed Circuit Boards, since there is only a single layer of substrate. All electrical parts and components are fixed on one side and copper traces are on the other side.

Double Sided Board

This is the most common type of board, where parts and components are attached to both sides of the substrate. In such cases, double-sided PCBs that have connecting traces on both the sides are used. Double-sided Printed Circuit Boards usually use through-hole construction for assembly of components.

Multi Layered Board

Multi layered PCB consists of several layers of substrate separated by insulation. Most common multilayer boards are: four layers, six layers, eight layers, and 10 layers. However, the total number of layers that can be manufactured can exceed over 42 layers. These types of boards are used in extremely complex electronic circuits.

A PCB (printed circuit board) mechanically supports electronic parts that are electrically connected with the help of conductive pathways, traces etched from copper sheets which are laminated onto a non-conductive substrate. Much of the electronic industry’s assembly, PCB design and quality control needs are set by standards which are set by the IPC organization. The main generic standard for the design of a printed circuit is IPC-2221A, regardless of the material used to manufacture the board.

Circuit boards consist of an insulator which consists of one or numerous layers of material glued into a single entity. The additional layers serve as grounding to the board.  The copper traces on the circuit board are either created by laying down individual lines mechanically or by coating the entire board in copper and stripping away the excess. By stripping away the excess, the needed printed circuits are left which connect electronic parts.

Many printed circuit board shops can help with the design process and offer high end features such as an auto router and trace optimizer which can drastically decrease the layout time. However, the best results for laying out a circuit board are achieved by at least some manual routing.

Custom PCB

These days, there are various kinds of circuit boards available in variety of materials and finishes, including FR4, FR4 High Temperature, Polyimide, GeTek, Rogers, Arlon, Nelco, Alumina, Ceramic, Bakelite, FR1, CEM1, and CEM5. The thickness of a circuit board varies based on the number of layers and can be as thin as 1.0mm (0.0394″). They can be single sided or multi-layered with cooper clad of 1-oz or higher. Although these are standard PCBs available in the market, yet you can get a customized circuit board to suit your needs. The key is to find the right PCB manufacturer to make the boards to your specifications.

A custom PCB can be made in several ways. For instance, flex circuit boards are designed to be very flexible. This allows the circuit board to be placed in positions which are otherwise not possible or to be used in wire systems. A PCB can also be used in satellites, spaceships and other machines in outer space. Rigid copper cores are designed in a way that conduct heat away from the sensitive parts and protect them in the extreme temperatures they experience.

Some circuit boards are designed with an interior conductive layer to transfer power to various parts without using extra traces. These customized needs are circuit boards that are ordered by companies to fulfill specific requirements with limited space. In addition, PCBs are also used by students and electronic hobbyists for their custom projects and applications.

Advantages

* Are cost-effective and highly reliable.
* Economical for high-volume production.
* Have color codes for different connections and are therefore easy to install.
* Mention the rating of the device which helps in their maintenance.

Disadvantages

* More layout effort.
* Higher initial cost as compared to point-to-point constructed circuits or wire-wrapped.
* Etching of circuit boards generates chemicals which are dangerous for the environment.
* Cannot be updated once it gets printed.

PCB prototypes and low volume PCBs are available in the market which are inexpensive and meet the majority of needs. Free PCB software can easily be found online these days. It is simple to use by an amateur and efficient for a professional. PCB circuit boards are designed especially for each circuit and make construction very easy.

These days, most people are familiar with VOIP even if they don’t recognize the word. Voice over Internet Protocol is something that many of us use from time to time or even on a daily basis. Services like Skype are a good example of a VOIP system.

Just What is a PBX? PBX refers to Private Branch Exchange, which sounds a little confusing, but is basically a method of switching phone lines back and forth to connect them in the world of offline communication. When referring to VOIP, the system is essentially the same in concept, only it works over a LAN or WAN network. These are data-oriented rather than circuit switched networks which we use in the real world phone systems.

You see, when you make a call on a VOIP system to a phone, a VOIP PBX or IP PBX, is responsible for making the connection between the virtual and the real life version. This is also in effect when you are calling from one computer to another, but there is no translation necessary between data and traditional phone lines.

With VOIP PBX, it’s a very simple matter to create a conference call and have several people in on a call. The technology has made it extremely easy to add new people to a call and without any additional preparation, you’ll be able to turn an ordinary phone call into one between several people. This is particularly useful for business calls where several people need to be in on a discussion or for long distance meetings. Families can also use this to connect on one call, no matter where they are in the world. It’s an amazing technology that still isn’t being used as much as it should.

What Should I Know? VOIP PBX is essential to making your calls online, but in most cases you don’t need to know anything about this. In fact, your VOIP provider is going to be responsible for this area. However, it does help to understand what they are talking about and to realize what some of the potential issues are with this type of setup.
What is VOIP PBX?

The reason some people still refuse to use VOIP is that they worry about the quality and reliability of this form of communication. While this was once a major issue, the technology has progressed to the point that these problems are far less frequent. Before we look at the issues that can arise, it’s important to know that when you communicate online, your voice data is divided into smaller pieces, called packets, for sending.

Possible problems include the following: – Too much information being received by the VOIP PBX Consulting at once. – Packet delay, when a packet gets sent through the wrong relays. – Packets getting jumbled up in the sending and reaching the receiver in the wrong order. – Packets arriving at different times at the receiver, causing ‘jitter’.

The result of having packets get lost or misdirected is a pause and possible loss of data while speaking. This is part of the reason why there is often a delay when using VOIP. This means you’ll need to speak slower when this happens. However, for the most part, the technology works well enough for even business calls and is far more cost effective.

Even though you may not need to know exactly how VOIP PBX works, it’s a good idea to familiarize yourself with the concept. VOIP is a very valuable addition to our communications systems and it is estimated that by 2010, 90% of communications sales will involve VOIP as it is rapidly growing in popularity.

Voice over Internet Protocol (VoIP) services, simply stated, converts your voice into a digital signal that travels over the Internet. As we all know, when calling a regular phone number the signal is converted to a regular telephone signal before reaching the destination. But VoIP allows making a call – directly from a computer or using a special VoIP phone or through a traditional phone that is connected to a special adapter. Moreover in locations such as airports, parks, and cafes VoIP enables you to connect to the Internet and may allow you to use VoIP service wirelessly.

As long as one has Internet access, it is possible to make and/or receive calls at any place and at any time. To appreciate this feature, one must know that even cell phones do not so extensively cover every remote and rural area as the Internet. Needless to state, all the standard features are present and available free – be it three-way conferencing, call forwarding, auto redial and caller identification.

To avail VoIP facility, one needs broadband (high speed Internet) connection regardless whether it is through a cable modem, or high speed services such as DSL or a local area network. Some VoIP services only work with a special VoIP phone, while other services allow you to use a traditional phone connected to a VoIP adapter.

Special VoIP phones will enable you to plug directly into your broadband connection – but if you use a telephone with a VoIP adapter, you can dial just as usual and the service provider may provide the dial tone. VOIP is capable of being integrated with all Internet based applications and services – such as file sharing, video/audio conferencing, and other similar services and applications.

Some VoIP providers charge for a long distance call to a number outside your calling area while other VoIP providers permit you to call anywhere at a flat rate for a fixed number of minutes. It is good to know that if you are calling someone who has a regular analog phone, that person does not need any special equipment to talk to you. Some VoIP services offer features such as three-way conferencing, call forwarding, auto redial and caller identification that are not available with a traditional phone, or are available but only for an additional fee. Another distinct advantage is you will avoid paying for both a broadband connection and a traditional telephone line.

A basic disadvantage with VoIP is the absolute necessity for Internet connection. Further, as all communications take place over the Internet, they will be unsecured and privacy will be not there. Quite a few VoIP services do not work during power outages and the service provider may not offer backup power. Sending Fax messages through VOIP connection is ruled out but the consolation is services such as e-Fax or Callwave may be possible. Another serious drawback is the lack of emergency calling facility. Most VOIP companies have perforce created own emergency call centers to route emergency calls. At least as of now, VoIP providers do not offer directory assistance and/or white page listings.

As most of us know, toll-free numbers begin with one of the following three-digit codes: 800, 888, 877, or 866. However, it is important to know that although 800, 888, 877, and 866 are all toll-free codes, they are not interchangeable. Toll-free numbers allow callers to contact others without being charged for the call. As a matter of fact, the charge is paid by the called party (the toll-free subscriber) instead of the caller. Toll-free numbers have been in vogue for long and have proved immensely helpful by many businesses for developing customer relationships.

Toll free numbers are easy to set up and come with multiple features including audio conferences, professional voice announcement feature, call screening, call recording, call forwarding, auto attendant, and more. More significantly, having a toll free number is an assured means of staying in touch with customers.

Before learning how to obtain toll-free numbers, we must know that there are toll-free service providers called “Responsible Organizations” or “RespOrgs”. The RespOrgs may not be telephone companies but they have access to the SMS/800 database, which contains information regarding the status of all toll-free numbers. RespOrgs are certified by the SMS/800 database administrator, and authorized to manage the toll-free service.

Persons wanting a toll-free number must contact a RespOrg or other toll-free service provider, who in turn, will access the database and reserve a number for the subscriber. This may not be difficult as there are several hundred RespOrgs and toll-free service providers in the United States.

There are subscribers, particularly business owners who are keen on getting what are called “vanity numbers”. A vanity number is an alphanumeric toll-free telephone number that also spells a person’s or company’s name or spells a word or acronym that is chosen by the subscriber. Thus vanity numbers can help customers remember your business and your contact information. One has to ascertain from any RespOrg or toll-free service provider whether a specific “vanity” number is available.

As stated earlier, a toll-free number is referred to as an 800, 888, 877, and 866 by the area code phone number. With a toll-free number, you will receive incoming calls on your existing phone line at no charge to the caller. Please note there is no installation required. You will be able to identify the caller before you answer the call, if you have caller ID enabled on your Ring-to number. You can add on voicemail or you can use existing voicemail box if there is one.

Another question many ask is – How many calls can I get at one time? Please know your toll free number can accept as many calls as your ring-to number can handle. If your ring-to number has call waiting facility, then you will be able to accept more than one call at a time. If you don’t have call waiting facility, excess calls may go into your voicemail. There are also a few service providers that allow toll-free to cellular phone calls. Further, you can have as many toll free numbers as you want to ring into one line.

Obviously, customers love toll free numbers because they will not be required to spend to get information about your goods and services. It is an established fact that having a toll-free phone number for your business increases sales and brings customers closer to your business. There are many different ways business owners can exploit toll free number to increase profits. In all printed stationery, business cards, pamphlets, brochures, and catalogs, make sure the toll free number is prominently displayed. People should be reassured by the fact that the phone call to your business will cost them nothing.

As is known to many, Voice over Internet Protocol (VoIP) is a phone system for both incoming and outgoing phone calls using the broadband Internet – dispensing with the traditional method. Today, VoIP phone system is favored by many self-employed professionals and business houses for its several key features including voicemail, call forwarding, and caller ID.

It needs to be mentioned that VoIP phone system for business that regularly communicates with overseas clients as the savings can be enormous. Switching over to VoIP is not only cost-effective, but also relatively easy if you already have broadband Internet – the basic pre-requisite for using VoIP system. This is not to say that VoIP phone systems will never give the user any problems.

VoIP suppliers believe, and rightly too, that a well-informed user can be a greater beneficiary in using all the extraordinary features VoIP offers at minimal cost. One of the chief attractions of VoIP is sending faxes and the fact remains that many business houses do a lot of faxing.

It has to be conceded that faxing over VoIP is only an incidental benefit and can achieved only with moderate success and that too, after a few settings have been made on the fax machine. The settings include lowering the Baud rate to 9600 and disabling the error correction mode. You must also ascertain from your VoIP provider what codecs they offer, as in most cases a G711 codec would be required for using faxes.

Apart from faxing the most likely common problems that may occur and their likely solutions are:

Not receiving all incoming calls: If the IAD is unable to register with your VoIP provider, then there will be loss of incoming calls. If you have voicemail facility on your VoIP account, then your provider will route the call to your voicemail. You may ask your VoIP provider for providing voicemail, so that calls can be redirected. Another option is a feature called “Call Forwarding upon the Loss of Registration”. If this feature is enabled, then during loss of your Internet connection, the call will automatically get forwarded to a preset number.

Despite having broadband Internet, unable to make outgoing calls due to absence of dial tone: Check for a corresponding light on phone no: 1 provided you have a Linksys router/IAD. If there is no light, reboot the IAD. If the light on phone 1is present, then try connecting a phone directly to the IAD without any devices or splitters between the IAD and the phone. If need be, change phone cords and/or the phone.

My calls sound unclear and quite often choppy: Disturbed audio is usually caused either due to inadequate bandwidth or from Internet congestion. Contact your ISP for a higher level of service with more bandwidth. If you find the problem occurring far too often, let the ISP check your connection. VoIP providers sometimes offer a more compressed codec or bandwidth saver setting. Changing the codec is known to solve the problem in many cases.

There is an echo sound that is annoying: Decrease the volume of the phones to prevent feedback. Take out any separate caller ID’s or splitters.

Static or buzzing noise: Buzzing noise or static is most likely the result of analog or electrical interference into the phone lines or phone. Make sure the cordless phones are charged and do not have weak batteries in the handset. Change channels on the phone to see which one is best. Try connecting a phone directly to the IAD to see if the buzzing ceases.

One of the biggest concerns for anyone who decides to live abroad is how to stay connected with loved ones, friends, and colleagues back home. Certainly, the fear of being isolated and not in touch is something that prevents some from deciding to move to another country.

Expensive long distance phone costs and poor quality telecommunications service were once real issues that hampered life overseas. However, times have changed. Current technologies now enable low cost and even free phone calls to and from anywhere in the world. And, the quality and consistency of the connections are crystal clear, too.

Through the use of voice over internet protocol (VoIP) technology, anyone, anywhere can make a call by simply using a PC and an internet connection. The technology is readily available, convenient, and dramatically less expensive than traditional phone service. Because of this, it’s the ideal communication solution for individuals who have chosen an international lifestyle but still want to stay in touch with contacts back home.

VoIP works very similar to a telephone line, but instead of the phone being plugged into the wall, calls are made through an internet connection. With the use of software from a VoIP provider, it’s as easy as plugging in an inexpensive headset or USB phone and dialing the number that you want to call. If a computer has built in speakers and a microphone, no additional equipment is needed at all.

Skype is the most widely-known provider of VoIP technology. First introduced in 2004, the company has grown in popularity primarily because of their free PC to PC calls. By downloading their software, a user of Skype can call other Skype users anywhere in the world for free.

Skype’s service becomes somewhat more complicated when trying to call someone other than a Skype user. To address this issue, they also offer a “Pay As You Go” plan and a variety of subscriptions that are billed monthly or annually. Prices vary depending on where users call, and there are additional fees to be aware of. Thus, it’s a good idea to read the small print before signing up and placing your first call.

As part of Skype’s subscription packages, they also include voicemail, call forwarding, text messaging, and an online number to enable others to call you from a regular phone to reach you on Skype.

For those who make frequent calls outside of their local area, there are a variety of other VoIP providers that deliver even less expensive options than Skype. One such company, MediaRing Talk has been on the cutting-edge of VoIP technology for over a decade. They are a well-known provider with an easy-to-use service for calling landlines and mobile phones that is particularly geared to expatriates and others living or traveling abroad.

Currently, MediaRing Talk offers free PC to PC calls globally just like Skype, but they also provide free PC to phone calls to eight countries including the UK, Canada, Australia, and China. Rates to other global destinations are amongst the lowest in the industry. The company has also recently announced that they will be launching a new program that will enable members to enjoy unlimited free call benefits to 50 countries for $12.99 per month. The new program will also allow members to take advantage of unlimited talk time on every call made.

“We completely understand the need for reliable, inexpensive communications when living overseas,” says Robert Pearlstein, vice president of business development and marketing for MediaRing Talk. “Our unique business model is particularly well-suited for anyone who wants the convenience and flexibility to call any type of phone without having to worry about racking up long distance harges.”

Another VoIP provider that is a favorite of many expatriates and international travelers is Net2Phone. Like with Skype and MediaRing Talk, users must download software to take advantage of Net2Phone’s service. They offer low per minute rates on PC to phone calls and a variety of broadband phone service plans.

However, they are most recognized for their international prepaid calling cards. The cards are ideal for individuals who don’t have access to a PC or the Internet but still want to take advantage of the lower calling rates that VoIP technology enables. By prepaying for time on the card, cardholders can enjoy rates as low as 5 cents per minute for international calls.

Cell phones are also definitely an alternative to relying on VoIP or local phone service for long distance. However, roaming charges can get extremely expensive and reception might not always be adequate in certain locations. A far less costly and more reliable option is to purchase a prepaid cell phone once overseas for receiving calls and using VoIP on your PC for calling out.

As technology continues to improve, there will undoubtedly be even more advances that will facilitate cost-effective, widely available global communications. In the meantime, anyone who has decided to reside offshore can certainly reduce their costs for long distance by taking advantage of VoIP technology.

One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. This is because the providers income comes from listeners and not from advertisers. Satellite radio services offer around 70 programs of commercial fee music channels each and you have a great variety of choices, from mainstream rock, hip-hop and dance music to folk music, opera, blues and many more.

Another great thing is the absence of static. You can be driving from the West Coast to the East Coast in the United States of America and you will not get any static at all on the way. The radio signal is digital, which means that you will get crystal-clear sound wherever you go.

Satellite radio tuners receive, along with the actual radio programs, an influx of metadata that consists of information regarding song title, artist, radio program and radio channel. This means that your satellite radio receiver will display all the necessary information about what you are listening to. For instance, if you hear a great song and you want to know which artist sings it, you just look at the receivers display.

All radio programs are uncensored. This is one of the reasons why artists like Howard Stern chose to move their shows on satellite radio. You can also listen to your favorite hip-hop songs without the interruption of those annoying beeping sounds.

Satellite radio programs also offer information about local traffic and weather conditions. The information is very detailed especially for those who live in big cities. If there is a major national calamity and other terrestrial radio stations will not work, you can always count on getting accurate information from satellite radio program. You can also listen to it online on your computer.

If you still are not convinced on why you should pay money for something that you can get for free, think about how much time you have wasted listening to commercials and all kinds of other boring stuff on terrestrial radio programs.

Traditional radio is not free, despite the popular belief. It is time-consuming and irritating because you have to listen to five minutes or more of commercials so that you can finally hear a song you like. The satellite radio subscriptions are very affordable and, for around 13 dollars per month, you get exactly the programs you want, which you can listen to wherever you are, at the best sound quality.

Satellite radio is great for you especially if you travel a lot. If you are traveling across the United States of America, for example, you can listen to the channel or channels you want during your whole trip, without losing signal or getting static. If you have a traditional radio, you will have to keep changing channels every hundred miles, but if you are using satellite radio you do not have to do that because the geographically availability of programs is not a problem. Satellite radio subscribers will soon get the chance to watch video programs as well.

Both Sirius and XM services have announced their intention of introducing in the near future a variety of video satellite channels that will have some of the great advantages that are currently available to satellite radio: commercial free programs, great quality of sound and vast geographical availability.
