4PIN PHOTOTRANSISTOR

PHOTOCOUPLER

(a) Infrared reflow soldering：

 Peak reflow soldering：

 Time of peak reflow temperature：

 Time of temperature higher than 230℃：

 Time to preheat temperature from 180~190℃：

 Time(s) of reflow：

 Flux：

260℃ or below (package surface temperature)

10 sec

30-60 sec

60-120 sec

Two

Rosin flux containing small amount of chlorine (The

flux with a maximum chlorine content of 0.2 Wt% is

recommended.)

Recommended Temperature Profile of Infrared Reflow

180℃

t (s)

10 sec Max.

(b) Wave soldering：

 Temperature：

 Time：

 Preheating conditions：

 Time(s) of reflow：

 Flux：

260℃ or below (molten solder temperature)

10 seconds or less

120℃ or below (package surface temperature)

One

Rosin flux containing small amount of chlorine (The flux with a maximum

chlorine content of 0.2 Wt% is recommended.)

(c) Cautions：

 Fluxes：

Avoid removing the residual flux with freon-based and chlorine-based

cleaning solvent.

 Avoid shorting between portion of frame and leads.
