How to distinguish the good or bad of the copper belt soft connection?
The weight ratio is as soft as that of the copper foil of the same material and specification. In contrast, the heavier weight is better than the light weight.
If the need for electroplating copper foil soft connection, but also need to see whether the plating is in place, each layer of plating is uniform, whether there is leakage of copper, inequality.
Check the connection ends of the copper foil soft welding (welding) whether the cracking phenomenon, or due to high temperature welding welding parts of the skin from a layer of little, this is a bad phenomenon, the welding quality directly affects the power capacity of the copper foil soft joining, so is the most important one link.
First of all, pick up a copper foil soft connection, check whether the surface is smooth, bright, polished symmetry, whether or not rugged phenomenon,
