QUOTE(niakulah @ May 2 2020, 01:43 PM) Yeah but they sell 3mm and 4mm. I haven't found any 3.5mm. i use 3mm eva foam. So is it better to go too loose or too tight?  with 4mm, you should cut it so that it's thinner. when the foam is sandwiched and squished between plate and pcb, they have room to go. |

Well I first heard about it last year when I saw the 7V, but I think it's been around longer than that.https://geekhack.org/index.php?topic=100896.0 Vibration reduction. Supposed to sound better. I want to see if I like it. |

yeah, it's been around for quite a while; and some people like it, some don't.
from my tests, the better plate type to use this is aluminum plates in terms of typing feel. it's not that significant for steel, brass, and carbon fiber. |

QUOTE(irsyadfy @ Apr 29 2020, 10:21 PM) so u need a better kibod? Probably a better proof-reader   QUOTE(niakulah @ May 2 2020, 05:43 AM) Guys, would this neoprene sheet be suitable to be put between PCB and plate? Neoprene isn't quite compressible, if you really want to use neoprene between the plate and PCB, I would suggest going for 3mm instead of 4mm. Good luck trying to cut out holes on it to fit the switches and stabs though. A sharp knife and a lot of patience is required. (Patience that even I give up on https://s.lazada.com.my/s.b0KK4 I measured the gap to be about 3.5mm, if the product is OK, should I go for 3mm or 4mm version? )Neoprene is good for in between PCB and case though, they are dense and heavy enough. I would recommend EVA foam in between the plate and PCB as horns had mentioned. |

That's one way to do it. in terms of sound, it will dampen it relatively, especially pings from metal plates.How would you describe the sound before and after? I still like the sound of my XD84PRO (stainless steel plate/sandwich mount) better than my IKBC (powder coated steel plate/tray mount). I'm hoping to make the IKBC to have that more solid bottom out sound. stainless steel plates is the hardest of all plate types that i have tested on tray mount builds. it has a hard and loud bottom-out sound. even with foam mod, it's still hard and loud. imo, steel > brass > aluminum > carbon fiber > polycarb (pc) in terms of hardness. by the way, different keyboard constructions produce different feels and sound. sandwich mount > tray mount in this case. |

I have plenty of sharp knives but from the small size of the squares needed, I'm thinking that wood chisels might be a better choice. |

Actually, I just remembered I had a small leather skiving knife that I don't really use a lot. It's almost the perfect size.I have plenty of sharp knives but from the small size of the squares needed, I'm thinking that wood chisels might be a better choice. 
Trace the plate holes in pen, knife straight down, strike with a rubber mallet . I also have a small leather plane whose blade is the exact size, but I think the resulting hole might be too tight a fit for the switches.

Does seem like it would be a tight fit.

MCO got lots of time  In a way I'm also "compensating" for my first MKB. The IKBC I accidentally killed by modding. Too rush to want to finish everything in 1 weekend so I could bring it to work on that Monday. Its death will not be in vain! |

the latest addition to my 64-key 60% reference build collection is a 64-key plateless tray mount build with gateron black.
the motivation behind this build is that i would like to know if it has the ctrlx/c/v bugs for via, https://www.caniusevia.com/ » Click to show Spoiler - click again to hide... « this is a build with flexes, and i like it. with touch typing, tuned gateron black works fine. .. and the answer to the bugs described above: well, this pcb is also working fine, without those bugs.
