Title: Lifted a single solder pad, how to repair?
Post by: Naweo on Mon, 27 June 2016, 07:00:48

Heya!

I lifted a single solder pad entirely from my escape key, and I am not sure how to repair it. I read online that I have to scrape the trace free from the solder mask, but it sounds dangerous and I would like to avoid that if possible.

What would be the best repair?

Thanks guys!

EDIT:

So apparently I need AWG 22 or 24 cable to connect the Escape key to the key next to it.

Does thickness or type of AWG 22/24 cable matter? Do I just expose some of the copper/wire inside and just solder it on the pins?

Can I just use any copper wire, and how important is insulation, like would I be able to cut an use an old ethernet or usb cable etc for the job?

Thanks!

Easiest fix is to run a jumper wire.  Just follow the trace to the next open spot (looks like the left pin of the 1 key).

So kinda like running a copper wire from each pin, like shown in the bottom here?

That is way overkill.  This is plenty:

Alright, I cut an ethernet cable and now it works. Thanks!
