- Optical power refers to the total optical output power collected by integrating sphere;
- The measurement errors of forward voltage, peak wavelength and radiation power are ± 0.2V, ± 3nm and ± 10%, respectively. The increase of injection current will lead to temperature rise, The light attenuation of LED lamp beads will be accelerated, and the service life will be shortened; when the LED lamp beads are tested or used beyond the above limit values, the reliability of the device may be affected and permanent damage may be caused.
- It is recommended to provide a good cooling environment or cooling system to obtain the best effect.
- The above test data are from DUVTek, and the actual curve will be different depending on the sampling situation.
- The patch shall be reflowed with environment-friendly 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 exceed 8 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.
