Layer stack-up

Layer arrangement in CEM-3 PCBs is important. It defines how many layers are used and affects electrical performance, strength and heat dissipation.

A typical layer stack-up is in the table below. It has six layers. Two signal layers between four power planes. Also listed are thickness and material of each layer.

Layer No. Material Thickness
1 Top 18 µm
2 Prepreg 175 µm
3 Signal 1 35 µm
4 Plane Vcc N/A
5 Signal 2 35 µm
6 Bottom 18 µm

Besides the layer stack-up, other processes must be understood. This includes drilling, etching, copper plating and solder applications. The type of PCB needed will determine which ones to use.
