PERFORATED ELECTROLYTIC METAL FOIL, PERFORATED ELECTROLYTIC METAL FOIL WITH CARRIER SUBSTRATE AND THEIR PRODUCTION METHODS

摘要

PPROBLEM TO BE SOLVED: To provide an electrolytic metal foil with an aperture, in which parameters such as the size, shape, position and depth of fine through-holes and the number of the fine through-holes per unit area, etc, can be designed according to the purpose. PSOLUTION: One side of the perforated electrolytic metal foil 1 is determined as a reference plane, and a plurality of fine through-holes 7 that penetrate to the other side are formed almost perpendicularly to the reference plane. Moreover, a carrier substrate and the perforated electrolytic metal foil are bonded together to improve the handleability of the perforated electrolytic metal foil having a plurality of fine through-holes in the thickness direction. In a production method for producing the same, an insulating protrusion is formed on the surface of the carrier substrate, and metal plating is performed on the surface of the carrier substrate on which the insulating protrusion is formed to form the perforated electrolytic metal foil on the surface of the carrier substrate.
