METHOD FOR FORMING RESISTOR ON INSULATING SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a production method of a printed circuit board having integrally plated resistors.

SOLUTION: This production method of a printed circuit board comprises: applying an etching resist to a part of a metal surface of a metal-coated laminated boards; forming a metal circuit by corroding and removing an exposed metal surface; peeling the resist; plating an exposed region of the core with a resister material having a volume resistivity of 500 to 1×10-4Ωcm; and trimming the resistable material so that the resistor has an insulating resistance equal to a predetermined ohm value.
