How to solve the problem of automatic soldering machine bad condition


Automated soldering machines are prone to leakage soldering during soldering: Leakage soldering generally refers to the absence of tin on the pads during soldering of automated soldering machines. The reasons for this phenomenon are:

First, the soldering iron tip does not touch the solder joint. At this time, we need to adjust the coordinates of the soldering point so that the soldering iron tip contacts the soldering joint, so that there will be no leakage soldering; the automatic soldering machine will inevitably encounter during use. To some bad problems, how can these problems be solved? Automatic soldering machine manufacturers

These problems mainly include the phenomenon of low solder joint precision, cold soldering, continuous soldering, stacking tin, tipping, and soldering, which are aimed at these poor soldering problems. In addition to debugging itself, there are some external factors.

1. The problem of leakage soldering in the soldering process of the automatic soldering machine is as follows: the leakage soldering generally refers to the phenomenon that there is no tin on the pad during the soldering process of the automatic soldering machine. The reasons for this phenomenon are:

First, the soldering iron tip does not touch the solder joint. At this time, we need to adjust the coordinates of the soldering point so that the soldering iron tip contacts the soldering joint, so that there is no leakage soldering;

2, automatic soldering machine in the soldering process is prone to the problem of virtual soldering: virtual soldering generally means that the solder joints can be seen in the welding process, in fact, the welding is not fishing or the amount of tin is not enough.

The main reason for this is that the tip of the soldering iron is not enough time on the pad or the temperature is too low. Therefore, we only need to extend the residence time of the tip or raise the temperature to solve it.

3, automatic soldering machine in the soldering process is prone to the problem of continuous welding: continuous welding generally refers to the phenomenon of two adjacent solder joints in the process of soldering together. The cause of this phenomenon is either due to too much tin supply or too little clearance between the two points.

In this case, the amount of tin should be reduced first, and then the position of the tip should be correct. If it is not correct, it should be adjusted in time.

4. The problem of stacking tin is easy to occur in the soldering process of the automatic soldering machine: the stacking tin generally means that the solder joint is welded into a spherical shape, and the legs and legs are not leaked out.

The main reason for this phenomenon is that the amount of tin is too large. At this time, it is only necessary to reduce the amount of tin to be applied. Another reason is that the leg is too short and the pad is not exposed. .
