deskthority

So, after finally finding time to myself I decided that I finally wanted too through with a build. This would be sort of a primer to the one I discussed waaaay far back about SKCC Alps, as I want to familiarize myself with soldering after a long while of not practicing.

Anywho, as I was testing my old PCB, which was dormant on a shelf for a good two months, I noticed part of the matrix wasn't registering. There are already diodes on the board, pre-soldered out of the factory. All the other keys work with the same method I am using. Furthermore, it is far past the date of return for this thing. I tested the board initially and I thought they were all registering. Any help would be appreciated on this front.

Heres the PCB for reference:https://www.aliexpress.com/item/daisy-4 ... 65170.html?

This question is rendered null if the previous problem is unfixable, but I saw a case plate combo sold by KPRepublic that caught my eye. However, after speaking with the seller, he stated that the mounts do not support ALPS keyswitches. I thought this odd, as the PCB is designed with ALPS and cherry in mind... Is it possible to file down the plate to fit ALPS?

Anyway, I hope that the first issue can be fixed, as the f key is markedly not responding. I know that I'm a moron for not building straight away, but I was too busy at the time.

when asking for help about a pcb, it is extremely helpful to post detailed photos of the pcb itself that has the problem, both sides so then we can help with what could be the issue, usually it is fairly simple things however without a photo there is little help that we can give.

The problem with the plate is that alps and cherry switches themselves are different sizes, cherry switches are slightly longer, but narrower then alps so whilst it may be possible to file the plate, it will take a lot of time in order to do so. If you want alps on a small board, i think the cheapest option would probably be the planck from OLKB or similar or just use the pcb without a plate. if you solder just one leg then you can adjust the angle of the switch first before soldering on the other lag to get the switches straight, not ideal but without getting a plate cut it is probably the only way to do it.

EDIT: After testing it again this morning, the LEDs on the bottom of the PCB lit up for a little while, and didn't turn off until I reconnected the PCB. I tested the pins on the PCB once more and the F key seemed to be working. So no worries on that!

Now I just gotta find a plate that fits this thing. I hope I don't have to get one printed because I am not working with much money on my hands. 60 bucks was the high end of my budget and that included the case and plate...
