Lifted a SMD RGB LED pad off a mechanical keyboard, fixable?
« on: November 19, 2017, 05:28:55 pm »
Hello everyone! I'm Darren from Johor Bahru, it is nice to know you guys.

I am a beginner in electronics but would love to dive into this field, it has been pretty interesting to work on a lot of different things thus far! This time is probably the first time i've ever accidentally damaged something, and am unsure on what could be done to rectify it

It's a mechanical keyboard with a few faulty SMD LEDs, so I had sourced for the replacements and have managed to fix most of the LEDs successfully, however on this last one, I had accidentally lifted off the solder pad for the one marked B (BLUE)

This is how normal, undamaged LED SMD solder pads look like




So yeah, for the B I had accidentally lifted the pad totally, i reckon it is poorly glued onto the PCB and was sensitive to heat..




I had tried soldering on an LED onto it, evidently the blue hue is not functioning, but as the -ve, R and G are soldered fine, green and red lights or its combinations work perfectly well, just no light when it is changed to blue.

I am hoping that there would be a way to fix this? Perhaps connecting a single core copper wire of some sort? I would appreciate any guidance given and thank you deeply for your time reading this..

PS this is how the back of the board looks like (the solder holes are there because I removed the mechanical switch for that particular key)

Hi there. Just peel off all the solder mask from the remaining track all the way to the via hole that is right there. Exposing the cooper. Then just make a bridge from the via to the terminal on the LED, either with a thin wire or with just tin if you can.
