1. Preheating PCB to remove moisture to prevent foaming , prevent damage of heat ;

2. Create temperature profiles for de-soldering, soldering; please contact us to get correct profile;

3. Desolder, Remove the BGA/IC from the board ,i.e CPU/GPU ;

4. Residual solder removal ,Remove residual solder from board and component pads;

5. BGA reballing, Attach new soldering balls if the BGA is to be re-used;

6. Alignment, Using your hand to assemble a new BGA or re-used BGA  to board ,

    Please make sure point to point .
