Metallising plastic conductor plates coated with conductive layer - by applying electric charge between soln. and plates to enable shorter process time

摘要

Chemically metallising a plastic substrate whose surface has been already partially coated with or electrically conductive layer consists of applying an electrical potential to the already partially coated layer just before or just as the substrate is wetted by the metallising soln. The other pole of the E potential charge is the soln itself. USE/ADVANTAGE - Esp for metallising printed circuits having through holes. By using the potential charge the process time in the bath is reduced and thereby the length of the appts is reduced.
