Table of Contents PCB printed circuit board design is one of the five major technical design skills introduced the size of the PCB and the arrangement of devices The printed circuit board size should be moderate. When the printed lines are long, the impedance increases, and not only does noise immunity decrease but the cost is also high; too small, it is not good

Table of Contents What is multi-layer PCB？ Basically, it refers to a circuit board that is printed and has a lot of conductive layers. It is expected that it should have a minimum of three conductive layers. Unlike a double-sided PCB, multilayer PCB is more complex. It has its upper and lower layers more the same as a double-sided PCB but has more layers
