The main problems in the production process of lead-free tin strip are as follows:

1. The incompleteness of lead-free solder. This problem is caused not only by the hot flux, but also by the properties of different welding materials. So to find the root cause, we should not only consider our products, but also consider the interference of external factors;

2. Lead-free tin strip welding product surface uneven phenomenon.There are several reasons for this phenomenon: 1. Welding surface environmental pollution, welding surface is not clean will cause uneven welding surface phenomenon; 2. Lead-free solder welding time, oxidation comparison verification will lead to uneven solder phenomenon;

3. Solder joints will be produced when lead-free tin strips are welded. The main reason is that the use of flux is incorrect. In order to solve this problem, we must keep in a dry welding environment on the welding time, and the preheating temperature to meet the actual needs, so as to greatly reduce the appearance of solder joints;

4. Lead-free tin strips will appear welding packaging, welding packaging and other phenomena that many people have never heard of, as long as the flux problem is caused by insufficient flux activity, and does not play the actual role of flux.

The above is a summary of the matters needing attention in the soldering process of lead-free tin strip. I hope it will be helpful to you. If you know more about the matters needing attention in the welding process of lead-free tin strip, please communicate with us and discuss.
