Title: I broke my QFR
Post by: Dany on Fri, 29 November 2013, 07:25:38
I was opening my keyboard when I pull to hard the PCB, then disaster...

I'm not able to solder these pins anymore, any solution?

I think you can try to fix the trace by using this solution

That's extremely neatly done!  (This is in reference to the fix in reply 1, btw.)

You could try some conductive ink to run the broken traces up to the pin holes, but you'd have to get the pins to stay in place - usually they'd be held in with the solder.

So something like ^ that might be the only way to go.

I did this exact thing from openeing my QFR too many times. I ended up soldering jumpers to nearby vias. Just follow the traces, power and ground are nearby, and the data pins are closer to the controller. I can dig up a picture I took if you need.

Follow the traces and solder individual wires to other solder pads on the respective traces.
To get better solder joints you could remove some solder from a pad with a solder wick and hook the wire around the existing pin.

Obliterated the pads for the USB connector.  You shouldn't be seeing the PCB.

The easiest fix is to bridge the traces with a wire, but you'll need a smaller gauge wire for that.

I think I used the wire out of a USB cable I destroyed to make the ergoDOX.

My perpetual issue is never having any hook up wire.

How is this easy to do just by opening up the case?

Id like to know because Im modding a QFR for the first time for somebody this weekend.

Shouldn't be that east, because CM sell replacement case tops that you can replace yourself without voiding warranty, and they wouldn't do that if it was so easy to break something just by opening the case.

Just be careful when you are unplugging the internal USB cable. Cooler master also changed their construction at some point, making the internal cable detachable from both ends. My (very early) QFR is soldered on one side and disconnectable from the other.

I think I included tips in my QFR disassembly instructions (with pictures) I wrote up. Ironically, this is when I broke it.

Yah, I noticed the connector when I opened the case and understood exactly what the OP did. Nice little surprise in there from CM/Costar. Thanks.
