Fold residue more

1. FLUX has a high solids content and does not contain too much volatiles.

2. The preheating is not performed before welding or the preheating temperature is too low (the time is too short for dip soldering).

3. Take the board too fast (FLUX failed to fully evaporate).

4. Tin furnace temperature is not enough.

5. There are too many impurities in the tin furnace or the tin is low.

6. Added anti-oxidant or anti-oxidation oil.

7. Apply too much flux.

8. There are too many scorpions or open components on the PCB and there is no warm up.

9. The component legs and plate holes are out of proportion (the holes are too large) to increase the flux.

10. The PCB itself has pre-coated rosin.

11. In the tin-bismuth process, FLUX is too wettable.

12. PCB process problems, too few vias, causing FLUX volatility.

13. Hand solder immersed in the wrong angle of the PCB.

14. During the use of FLUX, no diluent was added for a long time.

CNSMT  was established in June 2005

with a registered capital of 6 million yuan and more than 60 employees.
