This is just Gutz's personal experience. It won't apply to everyone or every board. But I think the insight from my little experience may help everyone.
Problem:
I have a PLU board that I modded and generally am quite happy with.
What I hated about my board was that the stock PLU layout has changed the right windows key into an anti windows key, and the apps key got changed into a trigger key for PLU's function layer which I don't use.
Intention:
I wanted to mod the keys back to a stock function as painlessly and unintrusively as possible. When I say unintrusive, it means I don't want to do anything irreversible such as cutting traces and scraping solder mask.
I posted on this forum but can't find my original post. Suicidal orange was nice enough to note that there are jumpers.
As you can see from my pix, jumpers 12 are shorted for both pads on both keys. That's a total of four jumper pads.
I removed all the solder using solder wick. I found the solder sucker poor for this task, since these pads are not through hole.
Then I tried shorting jumpers 23 instead, on the suspicion that this PCB was manufactured with alternative layouts in mind.
My guess proved correct, and now I have my happily-stock layout modded PLU keyboard!
At various times in my experience I have come across non standard layout keyboards. Next time you are burdened with such a board, why not check to see if there are jumpers that you can short on the PCB?
Special thanks to suicidal_orange. I did use flux cleaner and cleaned up my PCB after taking the photo.
