Note:

1. Alpha refers to the smallest crystal after recrystallization.

2. In the contract condition, the grain size range of the table is the regulation value, and the mechanical property and hardness are the reference values.

Product Description

Electrical high-precision Rolled Copper Foil Product thickness accuracy

Thickness Range(mm)	Thickness Tolerance(mm)
0.07 ～ 0.1	±0.003
>0.1 ～ 0.15	±0.005
>0.15 ～ 0.3	±0.008
>0.3 ～ 0.5	±0.010
>0.5 ～ 0.8	±0.013
>0.8 ～ 1.0	±0.015
>1.0 ～ 2.0	±0.020

Note:

1. This table stipulates that the product thickness accuracy is in accordance with the highest precision of the German eu din-en and international semiconductor materials association SEMI standard.

2. In the contract condition, if the user only requires positive or negative deviation, the value is twice the value in the table.
