How To Solve The Poor Process In The Use Of Laser Soldering Machine?

How to solve the poor process in the use of laser soldering machine?

Generally speaking, laser welding machines sometimes encounter some unfavorable problems during use. These problems mainly include low solder joint precision, virtual soldering, continuous soldering, accumulation soldering, sharpening, and missing soldering. For these poor welding problems. These problems have some external factors besides debugging itself, so how to solve these problems? The following is the answer for you by force automation.

Leakage welding in the welding process of automatic laser welding machine:

Leakage welding generally refers to the phenomenon that there is no tin on the pad during the welding process of the automatic laser welding machine. The reasons for this phenomenon are as follows: First, the solder paste or wire does not touch the solder joint. At this time, it is necessary to adjust the coordinates of the point to make it contact with the solder joint, so that there will be no leakage of soldering. One is welding. The surface of the disk is seriously oxidized, and the tin is not sticky at all.

The problem of virtual welding in the welding process of automatic laser welding machine:

False soldering generally means that the solder joints look okay during the soldering process, but the actual soldering is not strong or the amount of tin is insufficient. The main reason for this is that the laser spot does not stay on the pad for enough time or the temperature is too low. Therefore, we only need to prolong the dwell time of the laser spot or increase the temperature to solve the problem.

Continuous welding in the welding process of automatic laser welding machine:

Continuous welding generally refers to the phenomenon that several two solder joints are bridged together during the welding process. The reason for this is either too much tin or too little gap between the two points. In this case, the amount of tin should be reduced first, and then the correct placement of the tin should be checked. If it is not correct, adjust it in time.

Surfacing problems in the welding process of automatic laser welding machine:

Surfacing generally refers to soldering the solder joints into balls without the pins leaking out. The main reason for this phenomenon is the excessive amount of tin. This can be solved by reducing the amount of tin added. Another reason is that the pins are too short and the pads are not exposed. .

Other problems in the welding process of automatic laser welding machine:

The precision of the solder joints is not high, and the tips are drawn on the surface. The precision of the solder joints is not high, indicating that the solder joints are not smooth, and the sharp points indicate that the solder joints are not well formed or have burrs and tin tips after soldering. This reason is mainly caused by the poor fluidity of tin. Sometimes this is also caused by our improper parameter settings. Either the dwell time is too long, or the soldering temperature is set too high, both of which help. The flux evaporates instantly, reducing the flow of the solder. In addition, if such problems cannot be solved by parameter settings, the problem of solder must be considered
