Different technologies can be used in PCB assembly (Printed circuit board assembly) and this will depend on the final product which intends to be achieved or the manufacturing company’s preference. The major technologies included in this process are:

• Through hole technology
• Surface mount technology
• Mixed technology

Previous methods like point to point connections were replaced by more advanced techniques such as through hole technology. It was quickly embraced because of the efficiency.  In this form of technology, the electronic parts which are mounted with lead are inserted in holes through to the other side of the board and then attached to copper traces. The boards can be of different forms: single sided or double sided.  The leads are then bent at 90 degrees for horizontal installation.

While surface mount technology was there since the sixties, it was not embraced until the eighties. It came about with many merits like reduction in the cost of labor, high automation and enhanced the output production. Unlike the former technology, surface mount parts are smaller in size and allows smaller PCB assembly. Mixed technology on the other hand is a combination of the two methods though it’s not commonly used.
