Whenever I encounter such an issue where the pads I am trying to solder to have a high mass and absorb all the heat, I usually apply more heat through one of the following methods, whichever practically applies to my situation:
- Add flux;
- Crank up heat on the iron;
- Use a larger tip;
-
- Apply heat from my hot air station at 120-200 degrees Celsius until the area has pre-heated then while keepin hot air nozzle directed at that area, simultaneously start soldering desoldering.
