I've accidentally connected a pin to GND and it should have been left unconnected. It's pin 5 of an 8-pin SOIC so reasonably accessible but what would be the best way to actually disconnect it without stressing other pins? Note that the track that connects it to GND is very short and actually under the IC so isn't accessible. I don't really want to de-solder the chip so all I can think of is to try and wick up the solder from that pad and then gently bend the pin up. I've found that trying to wick it up is quite difficult because there's always some that remains under the pin.
