I have a Dual shock 1 PSB i am trying to solder but its been soldered before but i cut the wires off to move the pcb to a diff stick and am using the wires already in the stick connected to the buttons and the joystick inside.
My problem right now is when i solder it how do i know if it will work?
Also there is still very small pieces that i can’t cut of older wire/solder so what do I do about that do I resolder the wire onto the broken pieces and will it work? Or do I pick a diff spot on the pcb?
