Long story short, Hasu wanted to make 60% Alps PCB compatible with classic Alps keyboards so that it will be easy to source caps and cut the plate down to 60% size. So there were 9 PCB's available and I got one, PCB Nr.7

This is the PCB:
First step was to prepare the diodes, I used a piece of wood cut down to size so I could bend all the diodes :
Now the hard part, as a donor I used a NIB black Dell keyboard Alinh had, de-soldering the switches was a pain but that was not the hardest part.
I had to cut down to size the steel plate, for that I used a Dremel and some cutting disks, I think I broke around 10 of them but it worked in the end

This is what was left of the Dell plate


Except for the short 1.75u Right Shift and Pinky Fn that I miss so much the board is great, I managed to put a layout that it is easy to use, I'm typing since yesterday on this keyboard and it feels really nice. I know people hate the black Alps, but I like them, they feel interesting. I didn't had any issues with the PCB, everything worked as it was supposed to.
It was the first time I got a chance to test and evaluate a prototype and it felt great


For soldering I used an Antex XS25 soldering iron with 1mm tip and 0.5mm 60/40 soldering wire. The Antex soldering iron was much better than the cheap one I used in the past, it allowed me to make much cleaner soldering points, a great tool all together. I bought this one directly from their web site, they have fast and cheap delivery, and their products are of very good quality for a good price.
