When designing a four layer PCB circuit board, how to design the stack? Theoretically, there can be three schemes
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
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
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
FPC circuit board can be divided into single panel, double-sided board and multilayer board according to the number of circuit layers. The common multilayer board is generally 4-layer board or 6-layer board, and the complex multilayer board can reach dozens of layers.
PCB (printed circuit board), whose Chinese name is printed circuit board, is one of the important components in the electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers,
