Copper strips, plated with copper strips, lead frame and led module

摘要

The invention provide a copper strip capable of forming a surface plating layer with a higher reflectivity, a copper strip with the plating and a lead frame. According to the copper strip with a substrate plating growth surface, at least one of an amorphous zone or a zone formed by superfine grains is formed on the substrate plating growth surface according to the growth speed of the substrate plating in a manner that the substrate plating growth surface of the copper strip is uniform in surface.
