It is recommended in application that a 100-1000Ω load resistor be connected between the emitter and a negative
power supply between 5 and 15V. The output can be read as the voltage across the resistor. Alternatively, the case
can be connected to a power supply with the load resistor remaining connected to the emitter.
SOLDER REFLOW PROFILE
260ºC MAX
5s MAX
+5ºC/sec max ramp
60s MAX at 200 ºC
160ºC±10 ºC
90-120s preheat
-5ºC/sec max ramp
NOTES:
1. The above temperature profile shall be at the surface of LED resin.
2. Number of reflow process should be less than 2 times. If the second reflow process is performed, intervals between
the first and the second process should be as short as possible to prevent moisture absorption from LED resin.
Cooling process to normal temperature is required between the first and the second reflow process.
3. Temperature fluctuation to LED at pre-heat process should be minimized. (less than 6ºC)
