Introduction of Double-sided PCB

Double-sided PCB is a very important PCB board in the circuit board. There are double-sided circuit board metal base PCB boards, Hi-Tg heavy copper foil circuit boards, flat and winding double-sided PCB boards, and high-frequency PCBs on the market. , Hybrid dielectric base high-frequency double-sided circuit boards, etc., which are suitable for a wide range of high-tech industries such as: telecommunications, power supply, computers, industrial control, digital products, scientific and educational equipment, medical equipment, automobiles, aerospace defense, etc. Double-sided PCB is usually made of epoxy glass cloth copper clad board. The production process of double-sided PCB is generally divided into several types, such as process wire method, hole plugging method, masking method and pattern plating-etching method.
