What is the problem of small solder joints in wave soldering?

If such a situation has been useless before, then we should start with the analysis of the impurities of the solder. If the impurities are high, the melting point of the solder will become higher, so we try to increase the temperature of the solder, and it seems that it can be solved. If you can really avoid similar continuous welding, it is basically certain that the impurity exceeds the standard, generally speaking, the main reason is that the copper impurity content is too high.
Larger flux problems may also be caused.

1. If the flux is not enough or not uniform enough, you can directly increase the flow rate.

2. Lianxi speeds up the speed and enlarges the orbit angle.

3. Don't use 1 wave, use 2 wave single wave, the height of the tin does not have to be 1/2, it is enough to just touch the bottom of the board. If you have a pallet, then the tin surface should be on the highest surface where the pallet is hollowed out.

4. The board will be deformed.

5. If 2 waves of singles are not good, just use 1 wave to punch and 2 waves to hit the pins low, so that the shape of the solder joints can be repaired, and it will be fine.
