Hey all, have I damaged this xbox 360 controller circuit board beyond repair?
The Pictures
- The Red circle is the side I managed to fix.
- The Blue circle is the parts I could not get to bind properly.
The issues and my process
So I had a pair of xbox 360 controller controllers with corroded battery terminal springs. I managed to successfully replace the first controller’s springs, but the second I was having trouble with. The solder would not bind to the pad and it would form a lump that would break off under any pressure.
I consulted the internet and someone mentioned I just needed to crank up the heat. That didn’t work and the binding seemed to get worse, further it looks like it is now burnt all the terminal pad.
The internet then told me to scrap away the surface as it might be residual flux and it should be fine underneath. It still fails to securely bind.
I suspect the corrosion ate so far into the device that the pad itself was too weak to bind. I also suspect I am an idiot.
Is there any saving this?
My Plan should I discover I borked it
360 controllers have additional terminals on the back which I might be able to connect to something instead of the battery pads.
To understand the original traces on each side of a circuit board, you can put a powerful flashlivht on the back to see through.
I can’t say if the hole is too wide and makes a short circuit with another close track.
Do you use flux ?
Have you cleaned the track with water on a coton tip ? (To remove battery leak) What kind of soldering wire do you use ? Shitty soldering iron does not stick.
I had the same issue with a circuit. Gently sanding and using flux solved my issue. But it was an ugly soldering. I am not proud of it. You are not alone.
