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.

Fabrication steps
Making a CEM-3 Printed Circuit Board is no small feat! It takes multiple steps, and following them accurately is essential for achieving high-quality results that meet industry standards.
Firstly, design the electrical circuit using computer-aided design software.
Secondly, print the design on copper-clad laminate with inkjet printers onto non-conductive paper, known as “transfer film.”
And thirdly, use etching to remove impurities and excess metal from the copper-clad laminate, making it impervious to electric current.
Manufacturers must also focus on industry standards during fabrication, and inspect the PCBs for any defects before shipping them out.
Fun fact: CEM-3 stands for Composite Epoxy Material Type 3, which is a flame-retardant substrate used to make PCBs for consumer electronics products. Fixing a CEM-3 PCB is like performing surgery on a tiny, obstinate patient who just won’t give up!
