Finished my second keyboard (xd84). First one (xd87) is working totally fine and I use it daily at work. The second one was intended for home use. However, I have the following problem. Some keys (Tab, Caps, W, A, F, G, J, L mainly middle row) do not seem to work 100% of the time. I found that when pressing the keycap in the top right or left corner, the button press is not registered. Every other key works fine in this way except those mentioned above. I tried to resoldier these keys but the problem persists. I even tried switching a key (Tab) but it is not easy to completely desoldier and put in a new key. And even the new key seems to have this problem..
So, I was thinking, bad PCB? Or more likely that I ****ed up soldiering somehow? Can anyone provide some insight? I am lost at this point and spent several evenings on this problem without any result. I rather not toss the whole keyboard in the bin if I can help it.
Thanks
