How the board surface is insulated
light weight, thin thickness, good bending characteristics!) And soft and hard combination plate (reechas, Soft and hard combination plate) -FPC and PCB birth and development, gave birth to a soft and hard combination of this new product. Therefore, the soft and hard bonding board, that is, flexible circuit boards and rigid circuit boards, after pressing and other processes, according to the relevant process requirements together to form a FPC characteristics and PCB characteristics of the circuit board.
Circuit board can be called printed circuit board or printed circuit board, the English name for (Printed Circuit Board) PCB, (Flexible Printed Circuit board) FPC circuit board [1] (FPC circuit board, also known as flexible circuit board flexible circuit board is poly Imide or polyester film made of a substrate with a high degree of reliability, excellent flexible printed circuit board with a high wiring density,
Circuit board name: circuit boards, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production and optimization of the fixed circuit.
Circuit board surface with solder resist (a special ink) coating, to prevent the circuit corrosion and disconnection, to prevent the welding point and more short lines caused by the line to adjust the amount of solder attached to reduce the weld copper dissolved pollution, saving solder , Increase the insulation degree.
