6.9 Assembling

PCB component assembly is the process of soldering or assembly of electronic components to a printed circuit board. A PCB assembly process may use through-hole assembly technology or surface mount technology (SMT) or a mix to both. In the former method, the component leads are inserted into the holes drilled in the PCB. In the latter method, a pad having the legs similar to the PCB design is inserted and the IC’s are placed or fixed on top of them.
