High concentration rosin flux

　　Notes on Flux Operation:

　　1. Check whether the proportion of flux is the normal proportion specified by the supplier.

　　2. When using the foaming method, please regularly check the air pressure of the air compressor. It is best to filter the water and oil in the air with more than two precision air filters. Use dry, oil-free, and water-free clean compressed air to avoid affecting the assistance. The structure and properties of the flux.

　　3. During foam coating, the level of flux should be at least about one inch above the foam stone. The adjustment of the foaming height should be about 1CM higher than the edge of the foaming.

　　4. During the use of the flux, if the amount of diluent is found to increase, the specific gravity will continue to rise. It may be that other high-density impurities have been mixed, such as water, oil and other chemicals. Find out the reason and replace all the additives. Flux.

　　5. Adjust the angle of the air knife and the wind pressure flow, and the spray angle is 10-15 degrees with the direction of the PC board. If the angle is too large, the flux will be blown onto the preheater, and the size will blow out the foam and cause poor soldering.

　　6. If you use a brush, you should pay attention to whether the brush is in contact with the bottom. It is not good to be too high or too low. It is better to keep the brush lightly in contact.

　　7. Pay attention to the adjustment of the spray when spraying, and make sure that the flux is evenly distributed on the PCB soldering surface.

　　8. The tin wave is flat, the PCB is not deformed, and a more uniform surface welding effect can be obtained.

　　9. When the tinned PCB is severely oxidized, please perform proper pre-soldering treatment to ensure the quality and solderability.
