Issue with my bm60rgb pcb??

[murphyE]

Hello guys, so i recently got into custom keyboards, and i finally decided to take this one step further and build mine! but i may have screwed my first build. let me explain myself
so i bought gateron yellow ink v2 since i really like them, and purchased a bm60rgb hotswappable keyboard pcb from krepublic.
And i've a problem : pvb works well if i test it with iron tongs, but there is no signal when i test it with my switches. So, is it because the pcb is not compatible with the switches ? or i'm just doing something bad?
Sorry if im really noob......
and also sorry if my english is not that pog im a frenchie snail eater.

have a great day!

don't mind the ugly bandaids under stabs and the nasty keyboard on top on the photo pls.....

seems rather strange that it would work when tested with a piece of metal but not a switch, have you check that the switches legs are not bent? or that they actually make contact with the sockets?
seems like your board is compatible with pcb mount switches so should not prevent them from making contact.

hmmm yes i have just verified those two things and legs are not bent and it's making contact so i really don't know what's going on... may have i ****ed up my switches by lubing and clipping them if i did it wrong?

[Sup]

How did you lube them please don't tell me spray lubing.

AHAHAHAHHh, no i watched a ton of video on lubing and clipping switches, i bought krytox 205g0 specially for the occasion..... spray lubing is kinda bad right ?

Not sure what you did when you "clipped" them, but if you have a digital multimeter you can set it to continuity mode and connect the red to one pin and black to the other (doesn't matter which) and push the switch to see if you get a connection.

sadly i don't have one...... sadly i don't have any stocks switches left so i can't test if it's due to pcb or swicthes and it really feelsbad

If it works with 'iron tongs' (sounds like something to move logs in a fire ) it's not the PCB.  Either you bent something in the switch (all of them? very unlikely...) or you put lots of lube in the wrong place (again, all of them? no) or clipping means cutting the pins and you cut too much off.

If you have cut them can you post a picture of the pins?

[br4n_d0n]

There are two possibilities I can think of and I've listed them below from least severe to the worst with potential fixes.

• You got lube in the wrong areas. On these types of switches there is a little leaf spring the gets pushed together when the stem in the middle moves down causing a connection between the two pins. If you happened to get lube between the leaf spring it could be causing it to not make metal on metal contact and thus not forming a connection even when being pushed together. This is hopefully your issue and to fix it would just require you to clean out the areas with a paper towel or something.
  
• You did something wrong with the clipping. I'm not sure what you would need to clip on any of the switches considering the switches being used are MX style and the PCB supporting 5 holes for direct PCB mounting. I've also never seen the need to ever clip the actual pins and would advise against that unless you really needed it for some odd reason. So, hopefully when you stated that you "clipped" them, you only cut off the extra 2 legs on the switch housing. Otherwise, if you clipped the pins and screwed them up, you're going to at the very least need to get some new housings if not new switches. There may be other ways to make it work, but I'm not sure it would be worth it.

It's ok guys i figured it out, for some reasons my switches were not working because of how i put the switches films.... thought i knew how to put them correctly, but it works perfectly fine now
thank you guys for your help even tho it was only my fault cuz im noob to this ahahah

oh and i just noticed in the whole thread i said "clipping" where i wanted to say "filming".... my bad chiefs
