Soldering Method

Soldering Condition

Infrared reflow

Package peak temperature: 235

°C; time: within 30 secs (210 °C or more);

count: twice; day limit: 7 daysNote (hereafter, pre-baked for 36 hrs at 125

°C)

(1) The second reflow should be started after the temperature of the device

which would have been changed by the first reflow has returned to

normal.

(2) Please avoid flux water washing after the first reflow.

VPS

Package peak temperature: 215

°C; time: within 40 secs (200 °C or more);

count: within twice; day limit: 7 daysNote (hereafter, pre-baked for 36 hrs at

125

°C)

(1) The second reflow should be started after the temperature of the device

which would have been changed by the first reflow has returned to

normal.

(2) Please avoid flux water washing after the first reflow.
