Before delving into the custom PCB assembly process, it is important to understand the different types of custom printed circuit boards. PCB is sometimes referred to as "PCB bare board" and is usually classified as follows:
Single sided PCB:The circuit pattern is only printed on one side of the circuit board, which is the simplest type, the most basic processing process, and the lowest cost.
Double sided PCB:Both sides of the PCB have circuit patterns, and the component density is higher than that of single-sided PCBs.
Multilayer PCB:The increasing density and complexity of PCB design have paved the way for the development of multi-layer PCBs. There are several layers in a multi-layer PCB, with pre impregnated material sandwiched in between.
Rigid PCB:Nowadays, most circuit boards are still rigid boards, which means they are made of hard or rigid dielectric woven glass materials.
Flexible circuit board:It is a thin and flexible substrate with excellent thermal and electrical properties. It is composed of high-strength polymer materials and is commonly used in mobile phones, disk drives, and cameras. Fine and tiny patterns can be printed onto flexible circuits.
Rigid joint plate:Rigid flex joint plate is a board formed by bonding rigid and flex plates together. Rigid flex boards and flexible printed circuit boards can also be single-sided, double-sided, or multi-layer.
