I’ve laid out a breakout board for this self-contained switching power module: https://www.ti.com/lit/ds/symlink/lmz14202ext.pdf
But I’m not sure what to do about the “exposed pad”. I don’t see how I heat it up enough for the paste (with the Hakko FX-888D or the hot air station), so should I just plan on applying some thermal grease? Conductive epoxy?
Should I put a plated through hole in the middle of the pad and get at it that way?
