black 35um Standard electrolytic copper foil for PCB
Introduction
The roll shape (from 1/3oz to 2oz thickness)width. In usual, it is from 500mm to 1295mm, the max width could reach to 1370mm.
The normal sheet size is 1295mm*1295mm, 1295mm*1092mm, 1295mm*990mm. it also can be cut to the size as customer’s requirement.
1/3oz, 1/2oz, 1oz, 3oz, 12oz, 14oz are popular thickness, and we can also provide surface treatment service.
Feature
