THE CHIP ON BORAD OR SMT Reflow Soldering Instructions
Number of reflow process shall be 2 times or less and cooling
Process to normal temperature is required berween first and
Second soldering process.
Recommended Soldering Pattern
(Units:mm)
Remarks:
If special sorting is required (e.g. binning based on forward voltage, luminous intensity, or wavelength), the typical accuracy of the
sorting process is as follow:
1. Wavelength:+/-1nm
2. Luminous Intensity:+/-15%
3. Forward Voltage:+/-0.1V
Note: Accuracy may depend on the sorting parameters.
