Terrific tip - I was able to use that same technique on a potted circuit board today and figure out which component had shorted. I had to keep putting the board back into the boiling water after about one minute each time because by that time the epoxy had gone rock-hard again.
It took a dozen times into the boiling water before I was able to clear off all the epoxy form one side of my 4"x1.5" board but it worked. Many thanks for the great tip!
Oh boy, its amazing, I removed all potted expoxy resin from a generator AVR PCB, thanks for share.
Was AVR pcb repaired?
What was faulty in AVR pcb?
How did you re-pot AVR pcb?
Nicely done almost ALL the videos on here had zero information about dealing with the epoxy , and you can’t fix the electronic components without getting the epoxy off safely , shows you have brains unlike most all the others doing their videos !
The marbles and glass for an insulating thermal buffer were cool ideas! Thanks for the vid! Neat!
Oh wow, that worked WAY better than I expected. Thanks!!
Steaming works great too. takes longer, but its safer for the electronics.
Thank you very much for your kind and smart teaching
Many thanks for sharing your knowledge, Greetings from Argentina and Good Life to All
great video! Thanks for sharing this. Do you think that a prolonged soak in a preset reflow oven would have done as well? Seems to me that you're heating the epoxy up to it's Tg. Once you get the entire mass up to that level, I wonder if a heat gun applied during the removal process might facilitate this process. As an aside, were you able to fix the board? :)
Thanks for the heads up. Wanting to try this on a Traxxas RC Car module. They're really proud of them and it's plausible that mine blew some FETs out.
curious to see someone find this video also coming from trying to repair a traxxas ESC... did you manage to repair it? I have a Xl2.5 that i am sure could be repaired.
@@EPYCMX turned out it was the motor. Sorry
Do you think this will work on an inverter board which has capacitors and stuff in it?
Thanks, gonna use this to unwind an epoxy coated motor.
Thanks from India 🇮🇳
Wow thank you so much, that was a big help, now i know how to fix an avr of generator,
Wow, great job. Very clean work.
the interesting thing about boiling in water is that the pot will never get hotter than 100C inside
This is very helpful, I'm trying to upgrade an ancient EQ module thats got potted daughterboards in the same way. THANKS!!!
I'm trying this right now with a Honda eu3000 inverter generator, inverter unit. Model#31310-ZS9-t23. Really hoping it works. RUclips should ad a photo feature on its comments.
decs1000 I'm about to embark on the same adventure for a inverter unit. any luck?
Were either of you successful? I’ve got a bad 2000 inverter board.
@@davesnacks I am wondering how you two guys went with this? I also have a Honda Generator inverter not working and am reluctant to replace it at $800
Haha! I knew there had to be a way to un-fry my Ninja's ECU. Neat!
Thank you so very much from tropical Brazil.
Excellent, best relevant vid on the tube..
feels so gud after seeing this video...will try definately.....just want to ask, what type of pot we should take to melt the pcs of glass...
Thanks for this video. I'm looking for a way into a Denso motorcycle ECU which appears to be polyurethane potting compound, but this is definitely going into the memory bank for future use.
did it work mr Shaunie, god an ac cdi ready to remove the epoxy señor.
Thanks for this tip. will try it on some old voltage regulators of motorcycles. these can cost upto 500 bucks . So if you can repair them , it will save a ton of $$$
You ever get one to work
How would you keep the water from damaging the circuits/chips? Is There a way to do this without damaging the housing? How do companies remove it to repair components that they have potted?
as long as there's no current going through it you should be fine, just clean it with isopropyl after you're done
Hmmm, wish I'd seen this video earlier, It's just cost me £80 for a module which I feel sure I could have repairer. Great video, thank's.
My question is, can you do it again in real time and zoomed in on the item you are cleaning up please?
I've seen alot of video with people using this technic and not one use a respiratory mask I think there are toxic stuff getting release when this stuff is boiling
The sky really isn't falling.
We got Tom Myspace back !
This is a possibility how we can depot a nst neon sign transformer cast in resin like my transco. Everyone claims impossible. But I will try this. I might have to hear it much longer. But it should be worth the wait! If it works, I will post video. #nst #depot #transco
Did thos work for you?
Yeah I've got one for commercial bagging line embedded in clear epoxy it's $600 a pop
how bout the gel type potting stuff on cdi on cars..its not hard like epoxy,thanks heaps.
Thank you very much.
Well done!
were you able to fix this?
great tip, thanks.
Thanks!
AMAZING, thank you!
Can I do the same with a transformer that is immersed in apoxy?
I'm just wondering if it can work on the dreadful eberspracher d5wz controller board?
Thank u man it's vary much helped me
thanks a lot for this video!
I have a Commodore 64 PSU that I’d like to remove the epoxy from, but I worry about water getting into the transformer coil, or the heat damaging any electrical insulation on the coil. It’s obviously attached to mains when in use so I don’t know if I should risk this method. Someone else recommended chiselling it away instead. Any views on this?
The transformer coil cal withstand temperatures way higher than the boiling point of water (100°C) and that includes its insulation as well. Obviously if your C64 PSU is in working condition then you don't need to depot it anyway.
Dude! Thank you so much! I have some old Bill Lawrence that are sealed into the pickup covers via epoxy. I want to unseal them so I can use the covers for new pickups. You didn't have to reheat it during the stripping process?
Did they really use epoxy? 90% of all guitar pickups are potted it in wax or other reversible material.
the only other things I’ve seen are pickups potted in a type of tree varnish/sap… Which looks like an amber colored fiberglass… And I’ve even seen some in a type of natural black tar. All of which are pretty easily removable… At least in comparison to epoxy… And I can’t imagine any decent quality guitar pickup being using anything else. Unless it was an early experimental prototype or something.
If you want to see something potted in the black tar stuff I was talking about... check out “Mr. Carlson‘s lab” he made a video on depotting a transformer.
@@hullinstruments the substance on the pickups I have is hard, like plastic. I ended up just heating it up enough for me to take a fine-edge chisel to the edges and separate the pickup from the edges of the cover and I pried the pickups out.
The substance is still on the bottom of the pickups. I couldn't get it off, other than the bits that cracked and flaked off.
Genius!
i want to remove epoxy glue from a metallic hole, can we use fire torch (direct fire flame contact) or red hot rod to remove epoxy glue?
Heat gun would be better i guess🧐
I clean the putty knives and trowels I use with epoxy by just pyrolizing it-turning it to ash.
Do it outside, it makes nasty fumes.
Will this also work for that red epoxy? I need to fix an MSD ignition box. Thanks
david contreras I'm curious too because I need to do the same to a MSD Digi 6 plus. Did the boil method work? If you haven't tried, I'll give it a shot this week and let you know.
Did either David or rudderify ever test this? I also have a msd digital 6 I wanted to test it on. Any help would be greatly appreciated.
Honestly guys… Each module is different. Even modules from the same company, made for the same application might use different potting compounds on different days.
Epoxy, conformal coatings, silicone fillers, or a dozen other types of potting materials are common. (Including tar and tree Rosen) But even stuff from the same batch might be a different hardness… Or have a different reaction to heat. It all depends on the mixture of a two-part material.
There’s just too many variables to predict. I’ve depotted at least 100 different modules from all types of industrial applications. And it has to be handled in a case by case basis. Hell I’ve even had modules come off of the same machine that were identical, one was hidden under a cover… And the other was somewhat visible and placed on the outside of the machine. The potting compound in the module from the outer part of the machine was hardened by UV light… Whereas the module deeper inside the machine had a softer and more pliable compound. Each had to be handled totally different… And they were so similar that they shared serial numbers from the same day of production at the same factory.
Anyway… I know this question wasn’t for me… But I figured I would give my experience and just put it out there the things I’ve learned tinkering with this stuff
@@Rudderify did this work for you?
I have to wonder how a pressure cooker would work?!
Cool. Did'nt know this is possible
Thats CRAZY youd think it would damage the unit
can u remove the solar cell from mini solar panel with out damaging it
it filled with so kind of clear epoxi or something
i need that solar cell for mini projects
please tell me how do i do it ???
This is awesome, I've been wondering how to do this for years without a lot of noise or aggressive chemicals. Would it work on the tar in old transformers?
Yeah like fly back transformers
@@adhil8918 those have that same acrylic based compound, so yes it would work, I’m hoping it’ll free a torodial transformer I have that’s half potted, because I want to rewire it to use as a beefy high current transformer
Do you think it will work on neon sign trasformer
Ethan is probably watching this video right now with his epoxy USB
Thank you 🙏🏼 so much you save my ass !!! ❤
Can all Resins be broken down this way. I have this key ring and I just want to give it a go.... I have no idea what kind of resin the key ring is made from.
It definitely doesn't work with all resins. I've tried this twice with two different projects and it resulted in no softening of the rock hard epoxy at all. The stuff I tried it on was black electrical potting compound. It may work on some, but I've had zero success with this so far.
how about steam?
Where can i get epoxy like this. i want to cover my server psu that i turned in to computer psu. the server psu has exposed wires that i want to cover.
At the Lowe’s (Home improvement store) in the caulking section. You can choose from clear or colored silicone. It’s much cheaper too.
would an oven be better, no water exposure.
What the is used?
can you please mention the potting material chemical name?
Without chemical analysis there’s no way to know which type of epoxy it is. It would be useless to know because different manufacturers use different kinds and some even use different kinds depending on the product or when it was made.
Have you lost your marbels?
You made it look difficult bro
Good stuff! I've got a rare Comsoft Victory board I might do this to so the security module can be dumped for MAME. Are you a member of arcade collectors website KLOV?
Did you ever fix the BurgerTime?
Absolutely didn't work
:18. Is it worth it does take a lot of efforts?
Yes I have ignition modules that cost $1000 a pair and have 3 that fail in testing. If you get it un potted you can repair or copy. The last European one I did was costing 450 Euro's plus shipping.
Trevor can you mail me? I have some inverter I need repairing if you would like to do it?
delicious
Looks more like ramentime
good job but i think this circuit will never work again
Wouldn't it have been better to use a small oven and avoid any potential water damage? Electronics and water do not mix well. Especially if it happens to have some sort of back up battery or capacitor.
Google "CERN dishwasher"...
A lot of people think circuit boards and water don't mix. They often preach to others about it, without direct personal experience. While water IS bad when the circuit is energized, water is ok as long as it's denergized and you throughly dry it before energizing.
I've run many filthy circuit boards through a dishwasher cycle. Gently dried them for 24hrs at 140'f. They work great after.
alternately you can just throw it in the microwave for a handful of minutes - worked for me - OR if it's s transformer you can just run a heavy current though it and turn it into an induction heater and let the goo just fall out on it's own
I hope nobody fell for your stupid troll idea. Putting any electronics in the microwave will blow the microwave, and the electronic device in question. Although, the transformer idea might work.
ummm NO not really- it's an old machinists trick to heat bearings etc ... just make sure you wrap it in MOIST towelette first! nothing more to it.

@@antigen4 If there's electrolytic caps under the potting, that's a quick way to damage them. They are at least easily replaceable but any other method is many times safer.
I'm fucked I can't put the thing I have in water xD
It does not need to be water, steam or air will work, but it take a bit more patience, if You use a hetgun, You need to be wery careful.
I don't thnk that circuit board will ever work again......
Haha, it acutally did. I had to replace some of the pins on that module, but BurgerTime is alive again.
Create! Well...Didn't see that one coming.....
Runze Liu Just soak board in denatured alcohol for few minutes to absorb any water then let dry, this will prevent corrosion from water and dry any water that may have gotten under the chips!
Nonsense. Worked in the electronics industry for years. A common circuit board cleaning method is a nail brush a running water tap, and cleaning solvent. As long as you make sure it's dry (we use a low temp oven for a few hours), it'll be fine.
THANKS!!!!....ALL TRY IT RIGTH NOW
