An extremely important part of today's electronic devices is the PCB, or printed circuit board. A basic PCB can be found in computers, DVD players, video games, watches, calculators and cell phones, to name just a few. All of these pieces of modern technology just would not function if they didn't have a PCB. Did you ever wonder how a PCB is made?

Companies which provide PCB services create the boards by placing a material which is epoxy based over thing copper layers. To make the production of these boards sufficiently cheap for buyer and manufacturer alike to be able to make a profit, mass production is necessary. PCBs are sometimes produces by hand, which is much slower, but manual production is necessary for some specialized products which are not in mass production. Handmade PCBs are sometimes necessary for a new electronic product.

A company which uses PCB services will agree on the design and layout before the start of production. If the required design differs from what is usually mass produced, then a reasonable price for this service can usually be agreed upon. Quality is of particular concern here. If ...
... a company is purchasing PCB services, then they and the manufacturer of the boards need a PCB test. If the PCB is different from those that are mass produced, as is often the case with smaller companies, it is still important that the product should be of good quality and reliable.

Companies these days are usually familiar with the term quality assurance testing. Tests are carried out on PCBs at various stages of manufacture, and the finished boards are subjected to random PCB tests, and in this way a quality PCB is ensured. If a company provides PCB services but does not randomly carry out PCB tests on their finished product, then you should avoid that company. You can think of the PCB as a map or blueprint which is used by an electronic device to move current to the various components which are attached to it. If a PCB test has not been carried out, then the blueprint has no value and the company could even lose money as a result.

There are lots of companies world wide which supply PCB services at reasonable cost, and carry out quality work. In the world of electronics, PCB tests are vital. If a company skimps in this regard, then you should avoid them. If you are interested in using a particular manufacturer, ask them for references from previous customer companies they have worked for. This will give you a good idea of the quality of their work and what you can expect from them. Even when you think that you have found a company which will supply the best PCBs for you, you should still carry out some PCB tests randomly yourself, in order to avoid any possible problems that could occur later on, and which could have been avoided.
