Do you know about PCB Assembly?

I am here going to discuss PCB assembly but before that let me explain in short detail that what is PCB. It will help you to connect the dots easily. PCB is short for printed circuit board whose main work is to provide support mechanically as well as electronically connecting the electronic components with the help of conductive pads, tracks, and other components implante d from copper sheets laminated onto a non-conductive substrate.

PCB assembly (PCBA) sometimes also called as PCA, is nothing but a bare board packed with varied electronic components in order to form a PCA short for printed circuit assembly. It can be carried through two different types of technology but in the end in both the processes components are soldered. First technology which is used is known as “through-hole technology”. In this process, the holes are surrounded by conductive pads and the component leads are added in these holes as these holes keep the components in place.

The second technology used is called as surface-mount technology (SMT). In this process, “the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB; solder paste, which was previously applied to the pads, holds the components in place; if surface-mount components are applied to both sides of the board, the bottom-side components are glued to the board”.

As I said earlier that in the end of both the processes the components are soldered to the board, these soldering can be carried out through various techniques which can help to fix the components to a PCB. Normally there are many types of machines which can solder the parts on the board but few of the small parts can be soldered by hands with the help of microscope except few components such as BGA packages.
