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.
