PCB is a thin board made of epoxy resin or fiberglass, which is coated with layers of thin copper films. PCB consists of various valuable metals such as Au, Pd, Ag, and Cu.
How to layer the PCB six-layer board best?
Layer as follows: TOP------signal layer 1 INNER1------GND INNER2------signal layer 2 INNER3--------POWER INNER4------- -GND BOTTOM---------Signal layer 3 is divided in this way to make the power layer and the ground layer tightly coupled; each signal layer is adjacent to the inner electric layer, and there is no directly adjacent signal layer, which avoids the layer Inter-signal crosstalk; high-speed signal lines can be arranged on signal layer 2, so that it can be effectively shielded by the ground layer and power layer.
