REFLOW SOLDERING PROFILE for LEAD-FREE SMD PROCESS
Notes:
1. Don't cause stress to the LEDs while it is exposed to high temperature.
2. The maximum number of reflow soldering passes is 2 times.
3. Reflow soldering is recommended. Other soldering methods are not recommended as they might
cause damage to the product.
