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 (“live – 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.
