Product Description

Special flux for wave soldering of electronic products no-clean environmental protection flux

 

1. Introduction
* TUOPU X-215 no-clean flux is a no-clean flux with low solid content (2.5% solid content), halogen-free and higher activity. It can be used in foaming, spraying and other forms.
* Resin active system has excellent wettability on the surface of bare copper and solder layer.
* The welding of multi-layer boards with metallized small holes will show excellent penetration performance.
* After soldering, there are very few residues on the PCB surface, and the solder joints are uniform and bright and full and can be tested without cleaning.

Note: √ represents the possible cause
1. The flux is in poor contact with the bottom plate; the contact angle of the bottom plate solder is improper
2. The flux density is too high or too low
3. The speed of the conveyor belt is too fast or too slow. If it is too fast, it will be sharp and shiny; if it is too slow, it will be slightly round and thick.
4. Too much anti-oxidation oil or deterioration in the tin furnace
5. The preheating temperature is too high or too low
6. The temperature of the tin furnace is too high or too low, if it is too high, it will be slightly round and stubby, and if it is too low, it will be sharp and shiny.
7, the tin furnace wave crest is unstable
8. The solder in the tin furnace contains impurities
9. Poor wiring direction and arrangement of components
10. Improper handling of the leads of the original bottom plate
