This is the newest mod that some people are praising right now.
Several known streamers have already tested it with success.
The general principle is to prevent the case to ring like a bell when typing, due to vibrations that are transmitted from the bottom case to the top case.
The top case, beeing a hollow part, is often the most pingy part of a case.
And the very simple solution looks to stick tape on either top or bottom part of the case (or both) to isolate them and prevent those unwanted vibrations of the top case.
The most dramatic demonstrations have been done on the Keychron Q1 board known to ping like hell.
The beauty of this mod is that it is easily reversible if it does not work (just remove the tape).
And looks to do wonders to remove the ping without changing the sound signature of the board like with adding foam for example.
Seemed too good to be true so decided to try on one of my boards, the Manta75.
Don’t let me wrong I love the sound of my Manta75, but while the alphas were sounding great I could detect a very subtle pinging noise when typing on the keys close to the exterior of the case (modifiers, arrow keys, …).
And after having typed on it for a long time this became to annoy me a bit, because as everyone in this forum I want the perfect keyboard on my desk
So put very simple electrical tape patches close to the holes of the bottom case, assembled the board and started typing.
The results ?
ALL ping … GONE.
And my board now sounds the way I wanted it to sound when I designed it, this incredibly delicious.
Now the questions to you guys are:
Did you tested this mod and did it worked for you ?
The second question is more complex.
Why do you think some boards don’t need this mod and some boards do ?
As for 2 let me try to give my guess first.
I think the top case pinging problem could be due to a lack of surface contact between the top and bottom case.
As an example my previous design, the Winghead, didn’t need the mod. This board uses a leafpring sandwitch mount, allowing to have a large surface contact between the top and bottom piece (and plate of course).
The Manta75 uses a leafspring bottom mount, and less surface contact.
Also for the Manta75 the top piece is powder coated, a rather grainy finish that can lower the surface contact compared to a smoother finish like anodization for example.
So IMO pinging could be due to lack of surface contact between top and bottom piece due to :
- less available surface due to keyboard design.
- more or less smooth finish.
- uneven flatness of top/bottom piece due to poor machining.
- number of screws (more is better ?).
