The soft connection of pure copper foil is formed by stacking multiple layers of 0.1 or 0.2 copper foil sheets and melting and pressing them through high resolution diffusion welding. How to identify the quality of pure copper foil soft connections? The editor teaches you the following points to pay attention to when purchasing pure copper foil soft connection products:
1. First, pick up a pure copper foil soft connection and check if the surface is flat, bright, polished evenly, and there are no unevenness,
2. Check whether there are cracks in the welding areas (welding ports) at both ends of the pure copper foil soft connection, or if the welding area has melted a layer of skin due to high temperature. This is also an adverse phenomenon, and the quality of the welding directly affects the power supply ability of the pure copper foil soft connection, so it is also an important link.
3. If pure copper foil soft connection needs to be electroplated, it is also necessary to check whether the electroplating is in place, whether each layer of plating is uniform, and whether there is copper leakage or inequality.
4. Compared to the weight ratio, pure copper foil with the same material and specification for soft connections is better for heavier ones than lighter ones.
