I would like to clean my PCB with IPA (Iso-Propyl Alcohol) after soldering, since leakage currents at RFx & RFC pins are higher. Is it safe to clean the PCB by dipping in IPA ?. I am asking this because i am worried, whether moisture might enter the hermetically sealed package and damage the switch.
Yes you can use Iso-Propyl Alcohol for cleaning the PCB. Please do not leave the board for long time (I mean for hours) in IPA, use IPA it for cleaning only.
