PE Foam FAQ I will update this with information regarding this mod as it comes to my attention, as I want to make sure those who try this mod are equipped with as much knowledge about this as possible. But as always, do this mod at your own risk! Improvements to my method: I saw this video (kzfaq.info/get/bejne/bNZlqcWU2ti1moU.html ) after posting the guide and I now believe that the method they used in that video is probably the best (making cutouts for just the stabilizer housings and wires). For some boards, this is not fully possible (namely around the spacebar), but aiming for something at least close to that would be ideal. To compensate for not being able to cut around the spacebar, you can actually add a small piece of foam to just the spacebar just like this video: kzfaq.info/get/bejne/lad0krF8vpjQXZs.html . The effect of this piece of spacebar switch foam seems to differ depending on the board. The GMMK Pro in the video seems to benefit from it a lot, whereas the effect on my 67 Lite is a lot more negligible (based on my own testing). How do I know my PE foam is non-conductive? If your foam is stated to be anti-static, ESD, or conductive (duh) it is conductive. I got someone I trust to test the conductivity of regular white PE foam with a multimeter and they confirmed it to be non-conductive. To be 100% sure that your specific foam is non-conductive, you'll likely need to use something like a multimeter to check (unless it's conductive properties are explicitly stated). Why do my switches sound "crunchy" after doing this mod? Chances are your switches are not fully seated, and you're hearing the sound of the foam being compressed. Double check that they're as far down as they can go! Why are my switches "ghost-pressing" or "double clicking" after doing this mod? Chances are your switches are not fully seated, or there is an issue with the pins. Is this better than tape mod? As with most things in the custom keyboard hobby, it all comes down to preference. Here's my sound test comparison of the two mods individually, as well as together: kzfaq.info/get/bejne/fb6imKaikt3Ufo0.html Why doesn't my board sound exactly like the Jelly or your 67 Lite? This mod produces a pretty loud sound that takes over the sound signature, especially in boards that are muted otherwise. Although, there is still obviously some variation: case design, mounting style, plate material, switches, use of sound dampening, dampening material, etc. all play a role. There is also a notable amount of variation between recorded sound tests sound and real life, so it might not even be possible to match a certain sound test's sound exactly. What happens if it's hard to peel off the thin plastic layer? If you're sure there's a plastic layer, try using something fine like tweezers - you should hopefully be able to peel it off like end the end of a tape roll. If it seems very very stuck on there you should be good to still use it with the plastic layer, but definitely poke holes for the large middle pin, and be careful when inserting switches! Depending on how strong the plastic layer is, you might get quite a few bent pins, but those are easy to fix. Be sure to support those sockets as shown in the video, and you should be golden 👍 If you have any more information regarding this mod, please let me know in the comments! If you or someone you know has encountered any significant issues with the PE foam mod, please drop a comment or email me at technologybrotherYT@gmail.com with the full details! I'm always interested in learning more and helping out.

This definitely makes budget tray mount boards along with o ring mount mod so good!

as much as I love the marbley sound of the PE foam case mod - I find it tends to ruin the unique sound signature of the switch and they all have the same marbley sound at the end.

Insane quality for someone with so little subscribers, good job man your board sounds great

The amazon link in the description came in clutch, i was woried i wouldn't be able to get it at the right thickness and it also be antistatic. Thx

I just did this to 3 of my boards (KBD8X MkII, 5 Degree and Tofu65) after finding out about it in a Discord server. The improvement in acoustics is actually shocking. All 3 boards sound MUCH more poppy and lively (which was especially needed with the 5 Degree).

just did this mod right after watching this vid, and at made a HUGE DIFFERENCE! and it only took about 15 mins. Thanks for the video!

gosheeeesh, u are one of the most, if not the most underrated keeb content creators out there, keep it up!

Foam mod is what tape modders wish they could be.

I have this in my portico now and it is an interesting mod, it makes it sound pretty marbley and more thocky than without the foam

i just took my keyboards packing and shoved it inside of it lol

Man, you're a freaking god for us average entry level enjoyers. Thank you for making this!

Thanks for the great info on how to do this mod... but I think the "before" sounds more satisfying on your board!

y know ur type of videos is exactly what i thought the keyboard community was missing

Damn. First I though you were using candles since in the thumbnail the pe foam was positioned like it lmao. Good job on the video nonetheless

You know what, even before you put PE Foam in there, it still sounded amazing!

The second last one in the intro was just 😩🤌

Technology brother face reveal got me feelin a type of way

i just did this along with the tempest mod and i have to say that it changed my board completely and in loving the new sound signature

Loved this video! Just subbed and it turns out I was your 1000th subscriber! Lol

bro, the sound is amazing

Why this shit make my mouth water, I just want to take a bite.

I love how this is my exact build! Wil have to pick some up.

your keyboards sounded good even without the PE foam mod

QUESTION: I put a 1.5V battery under a sheet of PE foam. My logic was: To take a multi meter measure of a battery wrapped in PE foam. If the multi meter showed something when touching the wrapped battery with the leads - then the foam is conductive. If no measurement - then it is not conductive. Well, took a measure and it showed 1.5V. So my question is: is my method correct and is my PE foam conductive? Thanks!

Dang this video was extremely well made! Thanks for including me!

This is awesome, your video quality is🥵

Love that tkc sticker lmaoooo

I was watching ASMR Keyboard full blast with my earphones and fell asleep and woke up because this. I forgot about auto play lol.

Love video like this, short, sweet, and straight up to the point Edit: I subscribed because your videos are like that :)

I love when every switch sounds the same and the only sound is foam

sounds like the pe foam makes the keyboard sounds clackier? I have a top mount cf plate gateron 8008 which sounds kinda muted with eva plate foam and poron case foam etc, might give this a try to see how it goes

imagine doing this and the tempest mod together...

I didnt expect this to work as well as it did. Great vid and tutorial as well

cute axolotl cable bite~

keeb still sounds fire withoiut pe damn

00:44 take a good look at the 🔍 recommendations, the internet never seems to surprise me🤣

Nice vid mate

Didn't watch the whole vid, but I heard that you said .5 mm or less is good but u get even more thock with 1.5 mm packaging paper and I also verified it

This sounds so crisp! Btw, why didn't you put PE foam within the stabs?

Since my pc isn't hotswap, would you know if it would sound any better if I just use it as case foam?

Thanks for this, subscribed.

Really loved this mod! Made my tofu65 aluminium + brass plate + boba u4t so marbly but was too loud for my (and my fiancee's liking). Unfortunately had to reverse the mod. Have you considered trying out other materials that are thinner (like paper)?

There are so many variables to thock

Are there any alternatives to PE foam? Maybe some kind of paper or cloth that closely resembles PE foam?

Hi I am new to this and I really love your keyboard!!! What is your build and how much did it cost? Thanks!

Is the stock silicone you mentioning the silicone dampener pad that KBDFANS release recently or it's just the silicone gasket that sit between the pcb and plate?

Do you have to make cut outs for plate mount stabs?

Can this mod be recreated with the kbdfans switch pads which to my knowledge is just like a bandaid mod for your stabiliser but for the switches?

which typing tool do you use? Nice job btw

why do I like the sound without PE foam?

I just put a towel beneath my keyboard and it does the exact same thing lol

just did it ands soooooo good sooo much thock and pop

Do you have to do anything different if your PE foaming a solder keyboard? I have a tofu84 and I want to do this mod for it! Excellent video can’t wait to try this out. :)

hi i have a question, the pe foam im about to buy says its anti static, is it the same as non conductive?

Amazing how much difference a piece of foam can make! How did you manage to peel the plastic off the foam? Ive been trying but cant seem to find an edge...

is there only a problem with static if you have a metal case. I have a plastic case and am wondering if there will be any electrical problems between the switches or the pcb.

Awesome video! Have you tried KBD Fans Switch Pads? Have you tried using both PE + Switch Pad or would this be an overkill already? What's your take on this?

I have one lying around but I don't know if it's non conductive or whatever it is

Trying this out soon. Can i combine the tape and the pe mod? Or pe mod is good enough on kbd67 lite?

What should i do with RGB leds on the pcb? Cut some holes for them? Cause i guess they will overheat if i dont =C And about ESD - is there an risks if i have plastic case for my keeb? idk about conductivity of my PE foam, so i'm a bit worried to try, but want so bad

This will block the RGB lighting.

So I put some PE foam that I sound around the house in the bottom of my case for sound dampening. Do you think it will short my pcb?

I have a multimeter, what exactly do I need to test to see if my pe foam is conductive? Amps? Voltage? Ohms?

I winged everything without watching tutorial(s) first and I managed to make 10 switches not working (pin bent so bad it can’t be fixed etc) LMAO. Watch this first before modding! 😆

Would you recommend also including plate foam or is the pe enough by itself?

:O can i use the pe foam that came with gmmk? i'm using it in my hotswap board right now withou any issues but i am suddenly nervous

Is the linked PE Foam confirmed to be non conductive?

I will be using pe foam sticker which is pre laser cut and need to paste it yourself on the pcb. Can I add another layer of pe foam?

My local enthusiast keyboard store are selling these switch pads made with different materials like IXPE, EVA and Poron. But the store advertises them as Anti-static and ESD materials, from what you have claimed these types of materials may cause damage, therefore should i stay away from these or what?

Did you put the pe foam below the silicone and foam or on top?

Could I possibly use the packaging foam that comes with the kbdfan lite r2 pcb? or anything within that kit. I'm in Canada, so I can't really seem to find any foam at a reasonable price

can i use this mod with packaging foam that came with my kb?? its redragon k530 if ur wondering

How do I check if the pe foam is conductive or non-conductive?

What did you do to get this board to sound like this before the pe foam mod, and the last video where you showcased this board. How do I get marble sounds? Do I need an alu case, a poly plate, and durok stabs? Running: the cheap transparent aliexpress case, an alu plate, gmk screw in stabs (holee and lubed), gateron milky black (lubed with dielectric grease, trust me it works) and a ymdk set of iso carbon caps. No foam what so ever. I'm possibly thinking about getting this weird 42 buck alu low profile case from kbd fans and durok stabs becasue my spacebar rattles quite abit for some reason.

Can you do cutouts for wire and housing near the space bar or is it not possible? For kbd67 lite. And if so, what do I do.

You can get antistatic pe foam

Do I no longer need to put PE foam under the stock foam? Just the one sandwiched between the silicone and PCB?

I looked at the link that you provided for the pe foam and went to the Question and Answer part of the amazon product. Someone asked if the foam was static proof and someone replied that it was. If it is static proof does that mean that it is anti-static?

about the thin plastic layer, does the orientation of where it is facing matter? like is it better when it is facing the pcb or plate?

Hey great video, can i do this trick on an anne pro 2 board?

The Jelly Epoch with no or foam is disappointing

Would I have the same effect if i use 2 1.5mm thick sheets or should I just use one? Is 1.5mm enough to make a difference? Or can I Just stack two together

But why does it do that?!

May I ask what you mean by case foam? Is it the bottom foam that comes with the kit itself?

Should I buy silicone is it safe

Is the pe foam that comes with the gmmk pro packaging safe to use?

I wonder if this will change the KBD67 lite sound?

Could you use toilet paper or any other substitutes?

Bruh i cant get pe foam from any where wth

How is the pe foam holding up now? Bought the same exact one and am planning to put it in my Tofu65

Could you recommend PE Foam in Canada?

I use Cherry MX Blue clicky switches 👍😎 and WASD linears.

Can this create static and brick the PCB, or is this not a concern?

is 1mm foam a bit too thick?

what if you were to use two layers of foam or a thicker thoam?

So you don't need any other foam between the plate and the pcb? If the board already has thick foam between the plate and PCB should I remove it to achieve this sound?

how can i remove the thin plastic layer? im sure my foam has it, but it just wont peel off

THis legit sounds better than a Jelly epoch!

So the foam you linked is okay to get?
