How to Waterproof Electronics (the clean way)

[@im_ricebowl]

Sam, you were one of my most favorite youtubers growing up and you influenced many of my new hobbies.... id just wanna say that fpv stuff have improved a lot and is slowly becoming more accessible.... rest in peace my guy

[@isaiahhiggins]

I was about to comment the exact same thing. I'm glad his videos are still up to keep inspiring budding RC enthusiasts, I know he inspired me.

[@haroldseaman4243]

He passed away?

[@JaydenLawson]

Just realised that this person has passed away :( Seemed like a great guy. Life is short - enjoy what you have and your loved ones around you.

[@JaydenLawson]

Back 3 years later and appreciating this more than ever

[@LeDribFPV]

wowww you've had much better luck than I with conformal coating... then again I used acrylic. I'll have to try silicone coating asap

[@Jrod_FPV]

Le Drib I've had good luck with acrylic by same brand... what issues were you having?

[@LeDribFPV]

Yeah the acrylic coating I used is the same brand. Applied the same way you showed. After a couple crashes in the snow things still just stop working. ESCs and video transmitters in particular

[@Jrod_FPV]

Le Drib strange... I haven't had that problem. Are you sure it's the esc and not the FC? Do your vtx and FC share the same power supply? my guess is you just need more coating... props off and add water to each component individually to troubleshoot. Merry Christmas!

[@Aaron16]

The acrylic applications listed on the MG chem lists "Automotive air bag controllers, Cell phones and Computer tablets components, Avionics" While for the silicon version it does not. So I'm guessing the acrylic would be better for sensitive electronics.

[@mrkrag]

According to Chemtronics, in regard to their line of coatings, this is the difference between acrylic and silicone. Almost seems like you should use silicone on most of it and acrylic on solder connections. "AR - Acrylic conformal coatings provide fair elasticity and general protection. As one‐part systems, they are easy to apply and remove. Acrylic conformal coatings are recognized for their high dielectric strength, abrasion resistance and ease of removal. SR - Silicone conformal coatings provide excellent protection in a very wide temperature range. They provide good chemical resistance, salt spray resistance and are very flexible. Removal can be challenging, requiring specialized solvents and long soak time. "

[@Irigoyen4]

Hey! Great video!! I use that stuff too, although I will probably use it more often now, after watching your video. Also, this particular brand of conformal coating can be seen with an ultra-violet light after it is applied. I use the UV light from a UV "5 second" glue kit to see were the coating is and to see if I have missed any spots, works well! Thanks for sharing your stuff! M

[@robertnastasi4738]

UV light tip is great Thanks

[@LookatTheseMuffins]

Great video, thanks for making this. I loved your flight footage too. As I understand it, the acrylic version isn't as flexible or resistant to heat, so the silicone conformal coating seems better for FPV applications.

[@pLaCiDMoOoN]

Best (how to) waterproof video on KZbin! Thanks for sharing!

[@Jordanlolqwerty]

Miss you, brother. Glad you came around on my feed today...

[@brittonstarr114]

Super new to FPV, but I found your videos early on... the one thing that stuck with me, besides how helpful you are, you have quite the narrators voice.

[@mikescantlin5912]

Great video, and great flying. Rest In Peace, Samm💜

[@K3S01L2]

I use plasti dip on my circuit boards. Its rubber feel like material but its in liquid form when applied so it makes like one thick rubber mat over the board. Its also easy to peel of since mine is black (u can get other colors too, to mach your build) Its cost effective, my jar cost like 35 euros and its half liter and it is going to last me forever. It is also much better in my opinion to have some solid color than transparent since in that way you can be sure that every component on your circuit board is covered with it. It also doesn't ruin your welder tips since you can peel it off if needed and be sure there is none of it left on the solder joint section.

[@annunakkk1]

I didn't realize they were so fast and responsive. It's like a remote viewing experience. I need one! I'd want more than just a conformal coating though. A triple layer protection protocol, like conformal coating on the bare components, layer of flex seal, then something similar to a cell phone case.

[@NarcolepticLTD]

I have a jar of this stuff, and was contemplating using it on every component... just wasn't sure about the soldering of repairs later - you definitely answered that question :) great video!

[@MrRishik123]

5:09 oh look maaaa It's snow quad angel :D

[@gracklefpv8811]

Oh hay I recognize you from grandadisanoldman

[@mraffifpv1685]

Plastik70 does a similar job and you can get it at Conrad if you live im Germany or somewhere else where Conrad exists.

[@fibo12358]

lol, doing the Snow Bunny hop at the end! just shared ur video with fb RDU FPV, recommending a local flyer to use his wing to record people with speed and exotic cars while they drive. and, i mentioned the chemical and ordered a bottle of MG Chemicals 422B-55ML Silicone Conformal Coating, 55 ml - thank you!

[@A3Kr0n]

We use conformal coating at work a lot, and a handy tool I use is an "orange stick" to scrape coating off if it's thick. I think I got them at Mouser, but you can whittle your own I suppose.

[@ballwizz23]

You're a ridiculously talented pilot!

[@Maxbl4]

Used the same coating on tinyhawk freestyle, almost no issues after many crashes into deep snow. Only after 5-6 crashes in a row, when the board is really full of melting snow the vtx may start showing black lines. After drying everything is ok again

[@ruddersidedown]

West Washington is a way better place to fly than boring Illinois. Bringing my quad out there this year when visiting family. I'll probably hit every tree though. lol. Awesome video and thank you for all your research, trials and time putting all this together for all of us. I'm ordering this coating today and applying it this weekend.

[@WhiteCavendish]

Dielectric grease on the connectors would be good too. Used in automotive applications to waterproof electricals.

[@GingerOnWheels]

Are the motors already waterproof or did you coat those too? What about the little 2 pin connectors? Do you reconnect those and then coat them? Or is that what you were saying to do with the WD-40?

[@gymkhanadog]

I've used the spray on lacquer. I think I'm going to try this stuff for ease of application and lack of mess.

[@brocktechnology]

I believe it's people that share your sense of where is an appropriate location fly that have led to model aviation becoming very close to illegal here in Canada.

[@jamble7k]

if you are in the UK the product "EFSC15ML CONFORMAL SILICONE COATING" will do the same job :) no affiliation here.. just used it on my own quads

[@jamble7k]

i would say you could do at least 5 quads with 15ml...

[@jamble7k]

just make sure to use a waterproof hd cam ;)

[@SammSheperd]

That's unfortunate but also doesn't make any sense

[@jamble7k]

never had an issue with it tbh, covered all my flight controllers in it and leds and escs

[@SammSheperd]

***** I have a whole bag full of dead SPF3's they seem to die easily

[@Shadowcruise99]

Good to know that conformal coating does the job. Enjoyed the shots from Mt. Rainier!

[@hullinstruments]

This is a copy and paste including several snippets from articles, blog posts, and instruction Tutorials I’ve written over the years. Sorry for the rambling and I hope this helps someone I’m just an electronics geek with a somewhat respectable lab… Who repairs industrial control and automation equipment… Also restore and recalibrate test gear. And big into the laser Hobby. Anyway… Dealing with industrial equipment… I’ve come to learn a lot of things about waterproofing electronic stuff. Since I see hundreds and hundreds of industrial modules every year for repair… I’ve got a decent understanding of how it works. First of all… it’s a good idea to soak the board down really good with 100% alcohol or denatured alcohol. Then scrub the heck out of it with one of those small 1 inch disposable paintbrushes. Then give it another good soaking of alcohol with the board vertically so that it can drip off and take all the contaminants with it. Or better yet use an air compressor to blow off the contaminants and the alcohol. I buy 100% Iso alcohol by the gallon for about $15. And I keep it in a squeeze bottle on my workbench. (One of those squeeze bottles with a 90° angled tip that can be operated with one hand.) I use over a half a gallon a month at least! It really improves my work and I couldn’t live without it. There are a lot of waxy and oily residues that can come on new circuit boards… So degreasing really does help the adhesion and only takes a few squirts of alcohol and a few seconds. And the alcohol evaporates quickly taking any moisture with it. Second.... and probably most important. Try preheating your circuit boards before coating. They can handle a lot of heat But only need to be good and warm. Somewhere around 100 to 150°F would be plenty. This will help the epoxy flow in and around all of the components, And it will also adhere WAY better to the board. Also the longer cure time epoxy the better because it maintains much more flexibility. Some thing like 30 minutes is good, 60 minutes is better. Don’t get me wrong… I go through gallons at five minute epoxy every year and I love the stuff. But the faster the cure time, then the more brittle it will be. And with any vibration, it may can easily begin to pull away from the board or individual pins if it’s extremely rigid. So flexibility is great. Also when it comes to silicone… Be sure you get NEUTRAL cured silicone instead of acid cured. acid curing silicone will smell like vinegar and release acetic acid when curing. Therefore easily damaging copper and tarnishing other metals. Over time it will devour component legs and traces. Also, check out a product called “never wet“ made by rustoleum. You can spray that shit anywhere. On pcb’s, inside of power tools, on bearings, windings of a motor, Inside a brushless fan or motor, on your clothes, on your phone, hell I’ve even opened up GoPro’s and soaked the insides with this stuff when I was going to be in a precarious environment...... literally anywhere. It’s extremely thin (similar to a regular clearcoat…) But it’s hydrophobic and really is like magic.… Check out some of the videos demonstrating it. It really is amazing stuff if applied correctly. Another wonderful off-the-shelf product which is available to regular folks… Is flexseal. Yes I know it’s gotten A laughing with all of the infomercials on TV… but it really is an incredible product and cheap/readily available. Before flexseal, something similar was only available in large quantities by industrial chemical companies. But for $13 you can purchase a can of spray flexseal… or even the thicker caulk like tube. And its dang near bulletproof. If you’re worried about the epoxy pouring off the sides of the board… Then use tape or to make a dam around the board. In other words, stick the tape to the edge of the board with the sticky side facing in towards the circuitboard. Wrap the tape all the way around the board and leave the excess sticking up to make a damn so that you can fill it with epoxy. it leaves a nice perfect perimeter all around the board. Or if you’re wanting to cover the front and back of the board… the even better… Suspended the circuit board off of the table a little. Like the thickness of a coin or something similar. Then you can build a dam all around the board leaving a few millimeters extra on the sides of the board so the epoxy can flow over the top and down in under the board. That way you don’t have a bunch of open edges of epoxy that water can work its way under. But you’ve encapsulated the entire module in one slab of epoxy. If you use the dam building method… simply use some slices of cardboard like a cereal box… And a hot glue gun to build a little perimeter or wall around the board… Using another piece of cardboard or your work bench/table as a base to glue the dam to. The exact size you want. I would probably use a small plastic box a few millimeters bigger than my circuitboard. That way you can pour a little epoxy in the bottom, set your circuit board down into the box on top of the epoxy and spacer, and continue to pour epoxy on top of the board until it pours over the edges and connects with the epoxy around the sides and bottom. A small Tupperware container or any random little plastic box the same size should work fine. Once it’s cured you can pop it out and you’ve got a completely coated/padded module. But instead of a huge brick of epoxy it’s a thin coating with no seams or edges. That covers the entire front back and sides of the board in one smooth gel like coat. Just be sure to watch some acrylic/resin or mold making videos. And be sure to wax your Tupperware container/mold so that it can be removed and doesn’t stick in there. If it’s going to be some thing that’s really abused, then swap out all of your connector screws and crimp terminals with stainless instead of regular steel. And clearcoat any heat sinks or metal that isn’t coded in epoxy. It Makes a huge difference because the smallest amount of corrosion can easily spread under the coatings... wick will begin to delaminate it from the circuitboard. Any type of corrosion or patina whatsoever… Weather The white powdery oxide that forms on aluminum. Or rusting steel.... copper that’s formed a patina… it all Poses a huge hazard to the water resistance of a board. That’s the most common failure point I’ve seen which breaks down the waterproof barrier. For example… The white powder that forms and oxidizes on aluminum. That stuff somehow creeps up under and conformal coating with ease. Like it’s not even there. And most importantly…Keep in mind that NOTHING is waterproof. It may be water resistant but it’s better to leave it a bit exposed so you can dry it out later. The only exception is if you’re willing to completely pot it in a solid brick of epoxy. but then it’s completely unserviceable and it adds a lot of weight/cost. it’s always best to leave certain things open so they can be dried out after a mishap. Whether you leave it out in the sun on a dry hot day, or bake it at low to mid temperatures in an oven. the best methods for drying I found… Is 100% alcohol or denatured alcohol. Soak the entire board, transformer windings, motor windings, soak everything. It will bond to the water and draw it out as it evaporates quickly. Even then… I still put it in the sun While in front of a box fan.....or bake it in the oven. Just to be safe. This is a large cut and paste from several different articles, blog post, and instructional‘s that I’ve written over the years. Sorry for rambling… Hope this helps someone.

[@CINEAIRVIDEOPRODUCTION]

Thank Samm, nice flying, glad to see a crash, I was just asking how does he not hit those wires, I would hit them every time like a magnet, and then you did. LoL, nice to see others crash some times too! I use that stuff because I was burning out esc boards all the time. using the brush had 50/50 results. worked a few times but then the boards torched. the brush was way too messy for me and I guess I missed spaots some how, so I now us a small compressor and hobby air brush to apply it very nice finish and it works great. A little extra work but looks neat and works great. anyway thank agian and keep em flying!

Do I have to remove flux residues before applying conformal coating ?

[@madmarty7103]

your quad sounds great and there is so few wind noise. How do you do this?

[@ParaglidingManiac]

Do you think using this waterproofing technique on a DJI drone is an option? I do waypoint long range low level high speed flights mostly over lakes.

[@quadflyingmedic7988]

this stuff is awesome! I have been using it for quite a while and have had no issues at all. awesome flying from the moving car. if you have a black light that coating will glow if you shine it on the part so you can see if you missed anywhere or after working on it to be sure you didn't scrape any off

[@squaddingquads]

Rip you legend mate

[@chrisellingson123]

I have been using clear lacquer over the years on my homemade PCBs. This product looks similar to the thin layer of 'potting' compounds used in most automotive ECUs. Great for sealing out dust and moisture. Have you noticed any increased temperature in the components in dry conditions?

[@SammSheperd]

Well they are usually buried under layers of heatshrink and electrical tape so this is probably better

[@carlwelch5944]

I like what idea you had about protecting your boards, but what about the motors?

[@SammSheperd]

Brushless motors are already waterproof by nature. It's just coils of insulated wire. Water may cause bearings to wear out quicker though. Don't let it sit all wet for a long time. Warm it up and dry it out after flying

[@GibsonLesPaul2273]

My flat is about the size of your storage cupboard, I need to move to USA.

[@Radical9535]

seems more like weather proofing then water proofing will it be ok completely underwater?

[@goldendragon3147]

Two things you could use this for, 1. Driving in third person as if it were a video game, 2. Clearing the snow off your yard, very, very, slowly.

[@longwong1016]

I'm going to do this to my Rc P-51D Mustang latet. Still seeing if I can fly it well. First doinb fpv for me. You will be missed.

[@mathieusan]

I think one issue, even if the silicone actually resist high temp on its own, is the electronic cannot cool as well. Might not be an issue for the FC, but the ESC will get hotter faster, and might fail (or stop working) sooner, depending on their safety threshold on temperature. Likely not much an issue when flying in the winter time.

[@SesshomaruSama15]

dont overthink it a well tuned and well setup quad wont ever got hot. HEAT is wasted energy. not to be confused with speed of use of energy

[@normandb.1704]

[@woofbark4475]

Thanks for sharing the information and flight. Can you put this stuff over the barometer without affecting it?

[@SammSheperd]

I don’t use barometers for race drones and I don’t recommend covering the barometer

[@ReidMewborne]

Hey. Do you have to apply any to your motors? That's something I have been worried about. Also, I might apply some rubberized caps to those ports ... might be a little extra protection.

[@jasondonavich2758]

Will the spray version work just the same as the version you used? All the liquid versions are out of stock.

[@counter929]

i feel like this question was asked already, but what about using this on brushed motors? i saw something about brishless being waterproof(depending on quality) and something servo motors being brushed. hows about that? can brushed motors be "waterproofed"?

[@SammSheperd]

Brushed motors have physical electrical contacts inside which cannot be insulated without sealing the whole body. So it's more risky, but you could try to make sure the little brushed cans are sealed.

[@counter929]

i dint think ill try it unfortunately. there are open ports on the top of my 8.5mm motors and dont want to end up filling those holes and sealing my motors in place.

[@ronaldhighlen1041]

Brushed motor are all but waterproof as well a lot of crawler guys use them but impurities are hard on brushes.

[@crispyspa]

I used Rust-Oleum never wet before, it works pretty good but I think I'll try to scare some of this stuff up and use it instead.

[@mrtechnicalwin5912]

Cool vid! But what about the coil windings in the motors?

[@SammSheperd]

They are just that: insulated coils of wire. No exposed contacts

[@jogalong]

That has made my mind up completely. I'm getting that coating. Oh yes!

[@Aperson-sv2hc]

That last shot was silly, what kind of tracks would that be?

[@monkeyface291]

I know this is old, but how well does it work on cable connections. Looking to waterproof connections on a electric bike.

[@SammSheperd]

It is not meant for contacts, unless you don’t want to disconnect those contacts anymore. It’s for solid state exposed conductors.

[@monkeyface291]

Do you have any suggestions for contacts that cant be covered by shrink tube? They are just basic positive and negative leads connected to a odd shaped connector that is semi-exposed.

[@86Ivar]

have you tried candle wax coating?

could it be worthy to first solder everything together and do the waterproofing after then?

[@SammSheperd]

thats what I do

[@zod1167]

Does the water proof coating wear off or does it stay for a long time
