ABSTRACT:
A method of making a printed circuit network device including steps of depositing an insulating primary substrate layer on a temporary support member having a release surface, applying to the exposed surface of the primary substrate layer certain defined conductor areas, applying defined resistor areas on the exposed surface of the primary substrate layer and in electrical connection with the conductor areas, trimming the respective resistor areas to a predetermined resistive value, mounting the temporary support member with its several layers in facing relationship with a permanent support member, and thereafter releasing and removing the temporary support member from the mounted primary support layer.
