Before the PCB design starts, the Layout engineers will determine the number of layers of the PCB according to the size of the board, the scale of the circuit, and the requirements of electromagnetic compatibility (EMC). Then they will determine the component layout, and finally confirm the division of signal layers, power layers, and ground layers.

Under the current trend of high-speed and high-frequency, the more mainstream PCB materials include polytetrafluoroethylene resin (PTFE), epoxy resin (EP), bismaleimide triazine resin (BT), thermosetting cyanate ester resin (CE), thermosetting polyphenylene ether resin (PPE) and polyimide resin (PI), which lead to more than 130 types of copper clad laminates. Their common characteristics are that the dielectric constant and dielectric loss factor are very low or low.
