Who can tell me printed circuit board in the multi-layer and double-sided panels and the difference between the single-layer, multi-layer between the layers is how the distribution?
Multi-layer wiring layer, between the two layers is the dielectric layer, the dielectric layer can be done on the multi-layer circuit board at least three layers of conductive layer, two layers in the outer surface, and the remaining layer is synthesized in the insulation board
One side of the circuit, multilayer circuit board is between the board through the small hole connecting circuit `you carefully look at the multi-layer board` there are a lot of small holes above those holes in fact there are wires `is connected to a few boards
The difference between the multilayer board and the double panel and the single layer board refers to the number of boards, the multi-layer board has three or more layers of the circuit board pressed together
