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
Perfect normal temperature storage performance
High temperature anti-oxidization performance
High temperature elongation performance
Being used in the production of the different double-face and
multi-player printed circuit boards
Application:
Phenolic resin and Epoxy board
