Xincangtai storehouse FPC reinforcement plate of stainless steel is not easy to deformation, has high strength, can have the effect of conduction and induction, such as the gold fingers on the back of the reinforcing steel, used to increase the hardness and thickness of gold finger to pull plug, FPC steel reinforcing the thickness of 0.1 mm, 0.12 mm, 0.15 mm and 0.18 mm, 0.2 mm and 0.25 mm to 0.3 mm. FPC steel reinforcing material has stainless steel 304, 301 etc. FPC steel reinforcement used in mobile phones, video phone, laptop computers, aerospace, medical apparatus and instruments, such as digital cameras, automobile instrument suppression module or LCD link parts of FPC, most currently used in the mobile phone camera parts. Traditional FPC reinforcement plate is commonly used to open abrasive stamping molding, stamping process is coarser, however, tolerance, and the accuracy is not high, burr is difficult to clean, easy to circuit boards to form the effects of short circuit or open circuit, the lion's share of the sheet steel reinforcing USES a chemical etching process, etching process to solve the requirements of high precision parts and components in the industrial production, the advanced skills of FPC reinforcement plate, minimum aperture can reach 0.1 mm, and vertical hole wall, no burr; The flatness is kept below 0.02 mm, the minimum tolerance can be + / -0.01 mm, which is popular in China.
