Basic Tests Standards for Flexible Circuit Board

The basic test standards for flexible circuit board are:

1. The appearance of the substrate film surface and covering layer;

2. Deviations of successive discs and covering layer, bleeding of adhesive and covering layer, discoloration of the conductor under covering layer;

3. Whether the temperature resistance, humidity resistance, voltage resistance, bending resistance, and welding resistance meet the requirements;

4. Poor electroplating bonding, missing coating, etc.
