Reply to comment by _KJuns in Keychron q1v2 by One_Macaroon1592

Oh ok, yeah rn that's no flex but is not a thing that matter to me at all, to be honest I don't like it.I will try to get a silicon sheet so small. Plate foam u mean the foam between PCB and plate?

Yes, just remove it and also remove the stand-offs from the PC-plate, so that there is no hard connection between the plate and the PCB. The connection is save and holds just by the strength of the 'switch-pins-hotswap-socket-connection'. Bonus: You will get a much more even sound and there is no longer a weird warping of the plate and PCB (because Keychron made the platefoam a bit too thick for the smaller clearence there is). I think that will make the biggest difference in regards to your thock-intention. As it seems you got me right with the silicone sheet, I just recall it: Yes you would gain flex, but that was not the main goal. Now that I know you do not like it, it doesn't matter at all of course. But my intent with that is to disconnect the PCB from the silicone (hence the case).

Okok understand, the pc plate haven't already standoff (I think because is from AliExpress) so rn it isn't screw in with PCB, when I remove the foam plate should I remove gasket or not? I don't get it why disconnect the silicone to the pcb, can cause short of PCB?, sorry but I'm not English and I don't understand where you go with this.

I'm no 'native-english-speaker', too. So no worries. No, do not remove the gaskets, just the platefoam between the plate and pcb. If there are no standoffs you do not have to do anything in this regard. I thought you got the Keychron pc-plate. If you remove the silicone totally, yeah there is a chance of a short. But that's not what I suggested. I just mean you should get rid of the direct connection between the pcb-bottom and the silicone, hence get a thinner sheet of silicone to realize that. In your current state it's a tight sandwich with no air in between, really. This makes the gasketmount totally senseless and you really have kind of a sandwich-mount in the end. If there is some air in between and not a direct connection anymore, the pcb-plate-unit is more isolated from the case by just having the gaskets doing the job of the case-connection. In the end this means: you have a smaller area that translates sound. It is perhaps a bit quieter but also 'thockier'/deeper and poppier in my experience, in case of the Q1. The same explanation holds for the above thing with the platefoam, roughly speaking. Perhaps a FR4-plate would get you closer to your ideal, but I think your choice of the pc plate was a good one. Metal plates would be pingy and high pitched and the platefoam would be needed to mute that ping. So your well positioned platewise. The silicone sheet is there in the end to help the force break by muting the ping by reducing the bottom-case ping. It also makes the reverb-chamber of the case a bit smaller AND most important it's the safety sheet that makes a short impossible: If you, by accident, flex the PCB without anything in between it and the metal case you do get a short and may destroy your pcb that way. But with silicone or something else, like even your tempest-tape mod, in between, there is no risk. Tell me if something is unclear still. Best regards Q

No need to worries, now I get what u mean, last question is the max height of the silicon sheet is 0,5mm for don't touch the pcb or can in go with 1mm?

Ps: I'm Italian so German is gonna be worse than English ahah

_KJuns t1_irr1h92 wrote

I think so, yes: In my case, Q1V1, 1mm is just thin enough, but I think in your case, Q1V2, 0,5mm is the way to go (because of what I stated in my first post). Or you test it without any silicone at all before you search and buy one. There is a chance you do not need it at all, because your extended force break takes care of the ping-issue by itself. And your tape mod saves you from a short.
