#PCBA mounted crooked in case?

Hi,

I noticed that if I look at my keyboard from the bottom, the PCBA assembly is mounted unevenly in the case, with it being slanted slighty towards the right. It is especially obvious when the LEDs are on, especially on the spacebar. Does anyone else have this problem and is there any way to fix it?

Please provide some pictures.
This can be likely addressed by removing the module and then but it back in.

Also when you have removed the module please check the standoffs. Like to look if the metal insert ends flush with the plastic.

yea i tried this and can’t get it to be perfect unfortunately. It’s not really a good idea to unscrew the screws too much anyway, since that causes the pcba assembly to shift around when pressing a key in the corners of the keyboard

If it's uneven something need to cause this.

I doubt it's the mold for the case otherwise all units would have this issue. So all the standoffs should have the same height plane.

I assume a bad casting of your unit is unlikely. You can still check for that. You would need to check if the end of the plastic standoffs look fine.

For the threading a metal part is inserted. It the case these were assembled incorrectly they can may stick out partially and so causing an uneven height plane.

But it can also be that the module assembly is not really even. The PCBA is a little bit flexible. I assume the switch plate is made via a stamping. If that plate isn't even and the PCBA is screwed together with that, the PCBA would likely get uneven too. Due to the foam it can also be that the switch plate is fine but the that the PCBA is just screwed in unevenly.

#

So when you know what is causing it the issue it can be addressed.

#

In the case the case itself has an issue and you can not address it you can ask Wooting to get a new one. If it's caused by a bad assembly of the module you should be easily be able to fix it by taking that apart and assemble it correctly. If that has a bad part you can also likely request a replacement part for it.

It's basically your decision. It's not a cheap product and such an issue can be annoying after all. In the case it's easily fixable by your own I would say it's worth to do it. The keyboard was designed to be taken apart easily and it would take a while for the RMA process.

If the screws are screwed in to lose or if screws are missing the module maybe wobble.

It's normal that the entire right site sits a little bit deeper in the case as the left. While the plane has a very slight angle it's still even.

#

So the module is maybe not 100% parallel to the case it should still be even.

#

Had to say, for my two units the right side is maybe one millimeter lower than the left. So this is likely within an acceptable margin.

@crisp yoke I maybe got you wrong. At first I thought you were referring to the height plane. In the case you meant that the module isn't 100% parallel to the case, that is true.

#

Because it got deleted.

I took my caliper out and measured the height difference from the switch plate compared to the front lip of the case. The right side is 0,9 mm deeper for my ARM model and 0,8 mm for the AVR model.

#

So besides some minor unit to unit derivations I guess this is due to the mold. So maybe an oversight when the mold was created or it was considered within margin. I can't tell.

@pearl grove on your units, are the leds visible if you look at the case from the bottom at a straight angle?

#

on mine they arent; if i slowly tilt the keyboard down i start to see the leftmost leds first on the spacebar, but this is likely due to the fact that as you said, that module isint 100% parallel to the case

#

As I wrote, the right side of the module sits around 0,8 mm deeper on the front that the left side. So no, it's not parallel.

#

While I can't say why for sure, it's very much due to the mold. So besides from minor unit to unit variations I would expect that this minor flaw is the same for everyone.

#

To quote Mansen:

Yes this is not uncommon

I basically have...
Because the right side is lower compared to the left the module is not fully parallel to the case.
So of course when I look at a specific angle so that the LEDs are barely visible under the space bar they aren't on the right side but clearly on the left.
