Can desoldering and soldering to replace a capacitor which is part of an RC filter of an I/O pin cause that pin to develop an internal short to VCC?
This problem has now happened on 14 PCBAs. Any insight would be gratly appreciated.Regardsik

Resolved! Are LQFP STM32H750, STM32H753 and STM32H755 pin compatible?
Are all all H75* CPUs pin compatible. I would like to use LQFP STM32H750, but there is none stocked. Digikey has some H755 and H753 stocked. Can I use them, or what ever H75* CPUs Digikey happens to have when I'm ready.
