Got this PCB and hard-to-get receptacle. After minor soldering hiccups (hot air station is really recommended if you mess up the first time like I did) I got it to work.
Really great way to revive a keyboard from a broken Thinkpad- the resulting keyboard is really thin and you get the mouse (trackpoint) with no extra space at the bottom.
I would love at least schematic diagram, as it's hard to track bad solder joints on the PCB without it.
