(1/2) > >>

marhuum:
How is the most efficent, correct way to take apart a PCB which is a entirely laminated/glued in such that no one can normally act to flip around to face the PCB's PC ie. printed circuit side ?

It's old front-load Samsung wash machine's (but made in China) whose On-Off tactile push switch spring was dysfunction and then its pins have been broken too because has been  pull apart forcefully it's sitted at top-right spot
Useful correct guidance or info is invaluable, gratified

inse:
This PCB is potted, usually only to be removed mechanically.
Is the potting compound hard or soft?

Greybeard:
You can try hot air in combination with mechanical scratching tools.

I believe it's soft, as we can see a bit white due to as a scraped part on top-right corner, by end-sharp metal shaft

inse:
Or carefully grind an orifice from the back side to access the solder pads, might be less effort
