Hacking Hardware Modchip installation failed, ripped off a capacitor with its pad. Is this fixable?

Kaboni · May 11, 2024

This happened during an attempt to install a picofly modchip (Failed miserably).

Is there a way to somehow solder the capacitor back on? Is it just enough with one pad?

I've heard that the modchip installation can still be done with one capacitor, but I don't really know.

Which cap is this exactly?
With 1 pad only, the cap is not connected.
And it looks like that the pads might still be there.

Also, by looking at the result on the other caps, the iron tip isn't giving enough heat for the soldering.
This is also the reason why you rip the cap off in the first place.

Yes, there's also guide to use 1 cap shorted only for the modchip soldering.

It's the SP2 Capacitor, I don't think there's any pad left on the right side, it was removed completely, there's just solder leftovers. I'm not sure if it's still fixable
I'll gladly appreciate if you could tell me where to find a guide to install the modchip with only one cap, just in case I can't fix this problem.
Thanks for your help!

If I remember correctly, it should work just by ignoring this soldering point
Since these are power connections, 1 cap is enough, 2 caps for redundancy.

Also, before considering to ignore the cap, you can see if the ripped off pad is the ground pad.

If ground pad is ripped off, simply fix it by connecting the other end of the cap to a ground point by a jump wire. Matching it to the original soldering concept.

It's really hard to say without being able to see where the traces connect. Can you take another picture but zoomed out a bunch so I can see the little green line that leads away from the pad that got ripped off?

The basic idea for repairs like this is to add a thin rework wire (like those that are used for modchips) between the component and wherever the other side of the trace leads. Depending on how easy it is to tack a wire onto the thing at the other end of the trace, you may or may not be able to replace it.

As someone else said, some capacitors are redundant and used to add safety margins to the electronics. Some are absolutely required or the device will not work. But it's hard to say without seeing what it's connected to.
