How did you fix the pca back in place after having the heat stakes undone?

A hot glue gun is usually my go-to heat stake tool. Put enough pressure on the board to hold it in place, and put a little cap of glue on the stake.

Interesting idea.

I use the hot glue gun to fix wiring n the walls from time to time.
I was not sure if the hot glue would really stick strongly enough to the calculator PCB in order to resist the continued key pressings, so I never tried.
I will test it on one of my next repairs and see how it goes.

I have been using stronger adhesives on these keyboards, like Araldite fast cure variant. It takes more time to cure than just a few seconds on hot glue, and of course it will be much harder to undo the rivets later on if we need to do another repair.
