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

1. The incompleteness of lead-free solder. The cause of the above problem is not only the flux is too hot, but also caused by the material properties of different welding products, so to find out 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. It is mainly caused by the following reasons: 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 solder uneven 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 the welding time in a dry welding environment, and the preheating temperature to meet the actual needs, so as to greatly reduce the appearance of solder joints;

4. Lead-free tin strip 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.

No tin lead in the welding process, there are many large and small problems, the above problem is a more common problem, if there are more problems can also feel free to contact us, to help you solve the problem in welding, in order to create higher efficiency.
