Abstract

The invention discloses a method and device for preparing a golden finger circuit board. The advantages of both of a board milling process and a stamping process in a circuit board appearance processing manner are combined. By utilizing a method of sequentially performing local board milling and local stamping on the circuit board, the defects of low production efficiency and manpower and material resource material wasting due to the traditional process during board milling are avoided, and meanwhile, problems of relatively larger board edge burrs and white spot layering due to stamping are modified, especially appearance processing effects of high-grade golden finger circuit boards are improved.

Description

technical field [0001] The present application relates to the field of printed circuit board manufacturing, in particular to a gold finger circuit board preparation method and device. Background technique [0002] At present, some high-end golden finger boards have begun to be used in the field of optical communication devices. Such suppliers provide optical components, modules and subsystems for telecommunications equipment, optical displays, security systems, medical equipment, environmental protection equipment, aviation and defense systems. Due to the application of this kind of products in the assembly of precision systems of electronic products, the overall dimension tolerance is generally required to be ±50um; at the same time, strict requirements are put forward for the reliability of the gold finger. Insufficient withstand voltage and insulation resistance cause electrical performance to be affected. These strict requirements on dimensions and electrical performanc...
