

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

Two

Rosin flux containing small amount of chlorine (The

flux with a maximum chlorine content of 0.2 Wt% is

recommended.)

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.
