An Introduction to 2 Layer PCB Printed Circuit Board

The 2 layer PCB ( double-sided PCB )is a printed circuit board with copper coated on both sides, top and bottom. There is an insulating layer in the middle, which is a commonly used printed circuit board. Both sides can be layout and soldered, which greatly reduces the difficulty of layout, so it is widely used. To use circuits on both sides, there must be a proper circuit connection between
