Electrical precision resistances applying method for plastic circuit board

摘要

The method involves applying an electrically insulating protective layer (4) to a plastic circuit board (1). Electrically conducting tracks (5) are applied to the protective layer and electrical resistances (6-8) are formed by applying a paste resistance material. The precision resistances are formed by laser trimming of the electrical resistances. The glass containing material can be a glass hydrocarbon or glass-ceramic material.
