ABSTRACT:
A method of making a molded circuit board includes forming a polymer base with a channel and an intersecting through-hole. The base is conductively coated by means of vacuum deposition to establish a circuit line. After the conductive coating is removed everywhere except the channel and the through-hole, a further conductive material is provided on the coating. The base is subsequently stress relieved and planarized.
