Hi, thanks for the reply.
I tried testing the PCB with the tweezer method both before (while the switches were still soldered to the PCB) and after desoldering the entire PCB. Both times when I would test a socket, the entire row it's in. I've heard about using jumper wires on PCBs, do the switches need to be soldered in specifically for it to work? Sorry I'm not that familliar with electronics hence the PCB-centric questions.
What I meant by all the LEDs on the PCB works is that I was afraid that I might've broken the PCB after the entire desoldering debacle, so since its a Bluetooth capable keyboard, I plugged in the battery and turned it on and all the LEDs were working fine.
I also did a quick google on lifted pad/s, are there conductors in the walls of the hole were the switch pins go in? or is it just on the front and back surface of the PCB? If that's the case, I believe this might be the problem I'm worrying about since some of the switches I got off the PCB seems to have leftover solder + what I believe to be some sort of thin conductor, copper most likely I'd say.
Just additional information, it's my first time working on a solderable PCB so clearly I lack the appropriate knowledge to be working on one hahahaha
