Our common computer boards and cards are basically epoxy resin glass cloth based double-sided printed circuit boards. One side is the plug-in components, and the other side is the welding surface of the component feet. It can be seen that the welding points are very regular

At present, punching is the most used in batch processing of FPC circuit boards, and NC drilling and milling is mainly used for small batch FPC circuit boards and FPC circuit board samples

Special attention should also be paid to the packaging of finished products of flexible circuit boards, rather than simply stacking an appropriate number of flexible boards together at will. Due to the complex structure of flexible printed board

When designing a four layer PCB circuit board, how to design the stack? Theoretically, there can be three schemes

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 soft board reinforced board processing, FPC soft board reinforced board is unique to flexible circuit board, and its shape and materials are also diverse
