Inventor: ISHIKURA CHIHARU
IPC: C25D1/20
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To obtain electroforming films having stable quality free from deformation and distortion by executing the removal of a base material metallic substrate after thick electroplating by dissolving by chemicals, thereby removing this substrate. SOLUTION: A metal baser than an electroforming metal is first used as a base material metal in production of electroforming.

The substrate 1 is dissolved and removed by the chemicals, by which the electroforming films 3 are obtd. The removal of the substrate 1 is not by the peeling which is practiced thus far and, therefore, useless force is not acted on the electroforming films 3 and the films having the stable quality are obtd. Particularly in the case of precisely worked products, the shapes of their fine pores 4, slits, etc., are not affected at all.  The chemicals to be used may be any chemicals, insofar as these chemicals do not attack the electroforming metal and dissolve the base material metal; for example, nitric acid, hot concd. sulfuric acid, etc., are used when the base material metal is Cu and the electroforming films 3 are Pt.
