NOTE:
For the PowerCap version:
a.
Dallas Semiconductor recommends that PowerCap Module bases experience one pass through solder
reflow oriented with the label side up (“l(fā)ive – bug”).
b.
Hand Soldering and touch – up: Do not touch or apply the soldering iron to leads for more than 3 (three)
seconds. To solder, apply flux to the pad, heat the lead frame pad and apply solder. To remove the part,
apply flux, heat the lead frame pad until the solder reflows and use a solder wick to remove solder.
