How does the automatic soldering machine handle the tin tip?

The welding machine can be adjusted for three and all aspects. It completely replaces your hand. Your arm can be adjusted to any welding position you want. However, in the welding process of the welding machine, there will be poor welding problems. These problems are mainly manifested as missing welding, virtual welding, continuous welding, solder joint is not smooth, tin pile, tin tip and so on. In order to solve these bad problems, we should find out the causes of these bad problems and then solve them in a targeted way. So what is the reason why the welder welds the tin head?

1, the solder temperature is too high

Brazing temperature is too high, brazing time is too long, temperature is too high, flux volatilization speed is fast, brazing tip.

2, welding time is too long

If the welding time is too long, the flux will evaporate, and the electrode tip is prone to occur.

3. Iron is oxidized

The soldering iron head is oxidized, and the shape of the solder will be different from that of the normal solder, resulting in solder pull points; On the other hand, larger tin faces can also lead to welding heads.

4. Tin wire quality problem

The quality problem of tin wire is generally that the content of solder wire is small and the welding effect is not up to standard.

How to use automatic soldering machine correctly:

1, the solder must be uniform and smooth, no cold welding, leakage welding, continuous welding, oxygen welding or tin group.

2. The tin surface should be kept clean and free of debris. Avoid impurities causing bad effects on PIN pins.

3, the end of the solder should not be taken out too fast, so as not to lead to too large solder joints.

4, side solder head does not affect the appearance, Z good tin head does not exist.

5, control flux concentration ratio, otherwise it will affect the quality of solder.

6, solder can not make the tin surface contact with copper wire. Wuxi remains on the copper wire and skeleton.
