fightfing with an infinity keyoard – a switch is not working

[julientaq]

Hello guys.

Bought this infinity keyboard with MX-black, but stiff ain’t my thing.

SO i bought some 45 spring that i put in those switches.

Since i was overconfident, i broke some switches that I replaced with some steelseries 6G switches i had at home

Everything runs smooth, but the last button is not working. Impossible to make it work (i tried two different switches, but it looks like it does nothing)

Something else, some switches have resistor inside, some just a bended metal thing, and some have nothing. Does it have something to do with it?

The number behind the faulty switch is 63,

so here i am, clueless. and i’d be happy if anyone would have an idea since it should be my right arrow.

Thanks a lot guys.

Can you take a picture of the faulty switch? Did you open it and messed with the metal leaf spring?

If you replaced it, reflow your solder connections, you may have a cold joint.

here is the pic,





what’s a cold joint?

thanks.

Basically you have lifted the pad where the leg should be soldered (the lower one as you see it in you pic).
Bend the leg toward the other pad (upwards in your pic) and solder it there.
Then go to your other joints and do them again with about 10x the amount of solder you have used.
The joint should be a shiny cone that covers the whole pad.

Agreed, there is not enough solder on any of these joints, so it would not be surprising for you to find further problems down the road. Here is a quick soldering guide which should be helpful: https://learn.adafruit.com/adafruit-gui ... lder-joint

Thanks guys, i discovered that the last time i did something nice with a soldering iron was 1990,

The soldering joint were already there when i bought the keyboard, didn’t think it could be wrong,

So, i tried to do that

I think i made it worse now, didn’t i?





is there anyway to save pad that may be broken?
Do you think it can be the result of a cheap and bad quality soldering iron?

Thanks a lot
