Here, let’s to know the more details of copper foil is used in the flexible circuits. The cooper foil is very improtant part of flexible circuits.

1. There are two kinds of copper foil:
1>. rolled annealed copper foil(RA-copper)
2>. electrodeposited cooper foil(ED-copper)

2. The thickness:
1>. normally use 1/3oz, 1/2oz,1oz and 2oz four kinds;
2>. RA-copper: 1oz, 1/2oz, 1/3 oz or less thickness, but higher cost.

3. flexibility:
Rolled annealed copper foil is of high strength and can stand bending, two times for electrodeposited cooper.

Now, I think you know the Copper foil features of circuit boards more details. Ok, if you need more information, please do feel free to contact us.
