Today I tried to exchanged PA from one phone to another. I use phone (with 100% good PA ) but after exchanging to second phone PA is short circuited. I used 515 Celsius to solder and it looks that I damaged it. Can anybody recommend which temperature to use for exchanging or which technique to use. THANKS
