Partial plating method

Abstract

Abstract PURPOSE: To partially plate a metal having good adhesiveness and good quality with good accuracy by pressing a special masking jig containing electrodes therein to a body to be plated, and conducting electricity while flowing a plating soln. to the inside of the masking jig. CONSTITUTION: A masking jig 2 having an inside pipe 3 and an inside pipe 4 and using an electrical insulator material is pressed and touched to the plating part of a body 1 to be plated by way of a packing 6. The body 1 is supported by a supporting table 8 in a manner as to leave no spacings by way of a plastic object 7. An electrode 5 is provided near the tip end of the jig 2 and is used as the counter electrode for the body 1. Various kinds of pretreating solns., a plating soln. or rinsing water is introduced from a storage tank through the pipe 4 onto the plating surface, thence it is returned into the storage tank through the pipe 3. Thereby, the partial plating is accomplished economically with good productivity. COPYRIGHT: (C)1982,JPO&Japio
