Solutions to four common problems of automatic soldering machine

Published on: March 19, 2018 source: http://dajingling.com/news/358.html

Automatic soldering machine In the process of use, it is difficult to avoid some unexpected small situations. Even if a good manufacturer produces high-quality products, there will be a service life. Just as people are old, they will be inconvenient to move. When the machine is old, the flexibility will be reduced. In addition to the long-term use of machine aging reasons. There may also be problems unrelated to machine oxidation. It is mainly manifested in the phenomenon of false soldering, tin stacking and continuous welding. Aiming at the problems of poor welding during the operation of these machines, we summarized the following problems and solutions:

1、 False soldering problem: false soldering generally refers to that the solder joint appears to be OK in the welding process, but in fact, the solder joint is not salvaged or the amount of tin penetration is not enough. The main reason for this is that the retention time of the soldering head on the pad is not enough or the temperature is too low.

Solution: we can solve this problem by prolonging the residence time of the soldering head or increasing the temperature. If we don't know about the false soldering, we can specifically understand how to avoid the false soldering of the automatic soldering machine?

2、 Tin stacking problem: Tin stacking generally refers to welding and spot welding into a sphere, and the pin leg does not leak out. The main reason for this phenomenon is that the amount of tin is too large, and another reason is that the pins of electronic components are too short to expose the pad.

Solution: at this time as long as reduce the amount of tin or leave long pin can be solved.

3、 Continuous welding problem: continuous welding generally refers to the phenomenon that several adjacent solder joints are bridged together in the soldering process. The reason for this phenomenon is either too much tin feed or too small gap between the two points.

Solution: in this case, first of all, reduce the tin content, and then check whether the position of the soldering iron head is correct. If not, adjust it in time. In addition, we should also see whether the size of the soldering head is correct. If not, it should be adjusted in time.

4、 During the soldering process of the automatic soldering machine, sometimes the tin wire will be stuck: because the setting of the welding temperature is too low, the speed of feeding tin is too fast, and the feeding needle is too close to the soldering iron head, the tin wire at the front end of the soldering head is too late to melt, which is easy to cause the tin wire sticking.

Solution: adjust the position of the tin feeding needle to keep the distance between the tin wire and the soldering iron head, adjust the feeding speed and temperature setting in the machine parameters.

Only correct understanding Automatic soldering machine The possible problems can be handled easily and handled easily once any fault or obstruction occurs. Therefore, it is necessary to understand the use of automatic soldering machine.
