- The above test data are from DUVTek, and the actual curve will be different depending on the sampling situation.
- The patch shall be reflow soldered with high temperature solder paste,The peak temperature should not be greater than 260 ℃The peak time should be controlled within 10 seconds and the reflux time should not be more than 5 minutes.
- Reflow welding should not be more than once;
- It is not recommended to repair after welding dark purple led. When repair is inevitable, double head soldering iron must be used, and the product itself should not be damaged while operating carefully;
- When welding, do not apply pressure on the deep UV LED during heating;
- It is recommended to use convection reflow welder with temperature above 7.
