yes my friend this is a common issue , try to use preheater or heat the pcb in underside.

but if u use ir rework station then u can able to remove PA without damage.

use good flux to melt solder eaisly with hot air gun , but if u have good skill then u can sucessfully remove PA without damage.
I alerady replace more than 200 PA's with hot air gun but now I use ir station to rework.
so do practice in dead sets to improve ur skill .

good luck
