Printed circuit boards are extremely important in the electronic industry given that they are used in mass production of several electronic devices. These circuit boards are useful not just for mechanical support of the internal components but also for connecting them together. There are a large number of PCB manufacturers although the cost and delivery time could vary from one company to another. The complex assembly might need time to deliver especially when you need about 32 – 48 layers while less time might be required for one and two layers per assembly. Printed circuit board design needs quality control which is what differentiates from one manufacturer to another.

A functional printed circuit board assembly is where the electronic components are attached on the PCB to make sure that it works. Several different types of soldering techniques are used to fix the components both mechanically as well as electrically. Moreover, rigorous testing is important once the PCB has been completely populated. This includes testing with power off as well as testing with power on..

There are several important aspects of the PCB design. Schematic capture, determining the card dimensions and templates, deciding upon the stack layers as well as line impedance and ultimately to place the components and route the signal trace, are all part of the whole process of setting up the assembly. In some cases, even customized designs for mass production are entertained. There are separate PCB assemblies for GPRS transmitter or for electronic products. Telecommunication equipment makers might also have their own specifications which could be catered to. One can also go for full featured PCB with set volume requirements with the use of special materials like heavy copper, metal core and copper.
