I had a feeling that a problem like this would happen. Today I was going to have my dad(all his fault lol) teach the ways of the solder, but we couldn’t get started because his iron was to hot and to big and we had no flux. Sadly to say we still tried. He didn’t know that the pad was sensitive being a engineer Odd. He had the iron on the carbon pad and scorched the pad. Thinking oh he didn’t touch the green part of board I thought I was in the green(no pun intend). So I decided to test it with the little rubber carbon thing that comes inside the 360 controller. Every button worked but A which is the scorched pad. Long story short did he just burn off the carbon spray or did he do any serious damage.
Pics to help
The burn is on the pad and little spots on the green around it.
anything over 35watts is overkill. = 750degrees F. He probably fried every connection to that button.
try cleaning out that part again and inspect for visual damage. well, its a short so your pretty Fed.
I did what you said and clean it up it just had some caked on solder or carbon I don’t know. Anyway it works now I’ll search up on the iron watts I was kind of reading up on that anyway.
He just burnt the carbon. No serious problem. Just scrap it off to reveal the copper plate beneath. Then solder directly onto that copper plate. Use 25 watt soldering iron for PCB.
PS: if you wanna test it, use a wire and touch one end to the signal and the other to the ground, see if it gives out any signal.
if you are this unsure about what to do you really should do some reading before going ahead, i am not being funny but you have just fell at the very first hurdle (ok maybe second, you got the case off), i’d suggest a good read of the padhacking “stickied” thread.
