What is a 6 layer PCB?

According the name suggests, a 6 layers PCB comprises six layers of conductive material. It is basically a 4-layer PCB with two additional signal layers placed between the planes. ... The two surface layers help route low-speed signals, while the two internal buried layers help route high-speed signals.

Since the six-layer board has two grounds, AGND and DGND are separated and located on the second and fourth layers respectively, so the operation of the ground network is relatively easy. Lead the ground network pins of the top and ground electronic components with wires, and connect the via holes to the corresponding network (considering the production cost, try to use BVH（buried/blind via hole）PCB as little as possible, and use pads instead of through holes). Use as few pads as possible during the connection process, because the pads will bring Electronic Resistor and Capacitor effects and increase interference.When the Electronic connectors or components are not dense and there is a certain empty area, it is best to lay the ground. The ground is also divided into AGND and DGND, so the local grounding operation should be carried out separately. It is generally necessary to fill teardrops.
