Hello everyone,
I am trying to save my broken laptop and would like to desolder the WSON8 BIOS chip in order to repair the BIOS with a programmer.
I have now purchased a hot air soldering station (YIHUA 959D-II) for this purpose. I have already practiced a little on a broken board and desoldered components with it.
(350C with medium airflow and within a few seconds I was able to lift off the components with tweezers)
Now I'm afraid of destroying the BIOS chip if I desolder it too hot or for too long.
Do you have any tips on which nozzle size, temperature and air flow I should use when desoldering and, of course, when soldering back in?
And what else should I pay attention to?
I'm grateful for any tips
