Printed Circuit Boards are used to support and connect electrical components mechanically. They are inexpensive and are also used for the high-volume production. Before fabricating a PCB, manufacturers define its design vaguely. Here, a PCB prototype plays the key role in the creation of its design and facilitates the manufacturer to foresee if anything needs to be resolved in the PCB's design. In case of any failure in the prototype, a fresh prototype is created and is kept under custody till it performs well.

The process of PCB Fabrication goes under extreme conditions and a lot of steps are involved, like etching, engraving photos, multi-layer processing, drilling, masking, finishing, and finally electrical testing. PCB Test is done to check its efficiency and see if it delivers what it is supposed to do. Some manufacturers use different kinds of PCB specifications to make it perform, as required, such as using polyimide for flexibility, Arlon for longer life in high temperatures, and Isola range for PCB prototype. However, if the PCB Test comes out to be negative, then the entire circuit board is to be replaced or rectified accordingly.

On the other hand, talking about PCB Assembly, it is when electronic components are connected to a circuit board, we call it PCB Assembly. To connect these electronic components to the PCB, several techniques are used and two main techniques are, surface mount technique and through-the-hole technique. But, in most of the circuit boards, both these techniques are combined, to achieve maximum efficiency in the design and performance of the Printed circuit board. However, in some cases manufacturers employ highly skilled technicians to solder minute or small parts using microscope. They also use other equipments like tweezers, soldering tip, etc.

For a printed circuit board to be complete, not only equipments are important, but also PCB Fabrication, PCB Assembly and PCB Test. Hence, everything needs proper care. So, while choosing your manufacturer, do a thorough research about the company, its background, so that you get genuine and high-quality services in return.

After PCB Fabrication one of the most important processes, PCB Test, is done.
