NOTES ON HANDLING
1. Recommended soldering conditions
(1) Infrared reflow soldering
• Peak reflow temperature
• Time of peak reflow temperature
• Time of temperature higher than 220°C
• Time to preheat temperature from 120 to 180°C
• Number of reflows
• Flux
260°C or below (package surface temperature)
10 seconds or less
60 seconds or less
120±30 s
Three
Rosin flux containing small amount of chlorine (The flux with a
maximum chlorine content of 0.2 Wt% is recommended.)

(2) Wave soldering
• Temperature
• Time
• Preheating conditions
• Number of times
• Flux
260°C or below (molten solder temperature)
10 seconds or less
120°C or below (package surface temperature)
One (Allowed to be dipped in solder including plastic mold portion.)
Rosin flux containing small amount of chlorine (The flux with a maximum chlorine
content of 0.2 Wt% is recommended.)
(3) Cautions
• Fluxes
Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.
2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between
collector-emitters at startup, the output side may enter the on state, even if the voltage is within the absolute
maximum ratings.
