1 power layer, 1 ground layer and 2 signal layers are arranged in this way: TOP (signal layer), L2 (ground layer), L3 (power layer), BOT (signal layer).
After the covering film of FPC circuit board is positioned, it is necessary to heat and pressurize to make the adhesive completely solidified and integrated with the circuit.
FPC (flexible circuit board) is a type of PCB, also known as "soft board". FPC is made of flexible substrates such as polyimide or polyester film, which has the advantages of high wiring density, light weight, thin thickness, bendability, and high fl
FPC soft board reinforced board processing, FPC soft board reinforced board is unique to flexible circuit board, and its shape and materials are also diverse
Before designing multi-layer PCB, the designer needs to first determine the circuit board structure according to the scale of the circuit, the size of the circuit board and the requirements of electromagnetic compatibility (EMC), that is, decide whet
