How to Quickly Detect Motherboard Short Circuit with the Rosin Dispenser  

Sir can you share with me what is that dice if u use what name me I like that ok

​@shofikislam4140 it's called a rosin flux atomiser but lol , most of the sellers just send you a vape or a e cigarette 😂

Thanks for explaining this because the video didn't

The motherboard is still shorted and I know why

Thank you for this comment.

Why use something as expensive as rosin when a quick spray of alcohol Will do the same thing?

​@@DEGENEBABA Because with alcohol its hard to notice

​@@DEGENEBABArosin is cheap wdym ?

That's a great Idea

Oh shit thats a great idea, how do you use it?

@@joakoagui you can tightly attach the thermal paper to the board (you can fix it with a thermal pad so that it does not move). after that, try to turn on the board. if any element causes a short circuit, then it will heat up more than the others. as a result, a black trace of this element will remain on the thermal paper.

Вы не слышали про тепловизор?

How sensitive are flir cams

@@sargera1extremely sensitive, many factors greater than these other methods

Thermal cameras are fucking expensive tho. I can't wait for that recent advance in thermal sensor manufacturing that'll supposedly make them cheaper, making it possible for any consumer level smartphone to include a thermal camera.

How you can use isopropyl

​@@ChelseaKearyjust put alcohol on suspected area and then inject a small current in the area and watch what evaporates quickly.

Lol, slow down hunter.

Crack rosin? Hmm... I wonder if.. 🤔

Hahah crack pipe?? Not close to crack haha

😂😂😂😂😂😂

💀💀💀💀

What's the name of this products

Yuup

Just smart

What does vapor have to do with shorts?? I'm curious

@@johnathanfowlds7587 do you mean short circuit?

@@johnathanfowlds7587 the vapor is actually rosin it’s used as a flux to help solder flow in between two connections, in room temperature it feels almost like rock or hard candy, but when it heats up it turns to a liquid which aids in the flow of solder Rosin by its self is not electricity conductive this guy took it a step further and turned it to vapor and covered the board in it, when the vapor cooled it became almost like a dust coating on top of the board when he ran a current threw, the heat generated from the short melted the rosin in that area, allowing him to find exactly what’s causing the problem This technique is used in all sorts of stuff, dentists have a blue tablet that they’ll have you chew on, and under UV light it’ll make plaque glow, allowing them to find where you haven’t been brushing well Doctor have a similar thing with blood, they’ll put a contrast in your blood and it’ll show problem areas in an X-Ray Engineers will use a dye to color metal parts and that dye (or sometimes just a sharpie) will rub off in areas that are make to much contact, and will stay on the material in places that aren’t making enough contact, one scenario for this is mating two vary high tolerance parts together to make a seal; like valves in an engine It’s all for quick identification of a problem and it’s a really neat practice

Bruh that's a crack pipe not an e-banger lmao

Essentially, yeah 😆

OMFG 💀

Hahahaha nice!!!

😂

I thought this dude was going to rip a fat dab. That's how I start fixing my electronics.

Fr tho

@@_sticks_ you made my day

@@antkoos have a good one!

Thermal cameras are really pricey, and not that great resolution, wise.

@@Zaniahiononzenbei why not a great solution?

@@AntonySimkin the cameras have low resolution, which prevents you from seeing exactly what caused the issue. They also can't use standard optics, because standard optics are opaque in the IR range.

@@Zaniahiononzenbei sounds pretty accurate. Indeed, you can't use optics. Composed cameras may be a good choice (as in Caterpillar cellphone, where posprocessing adds low res thermal on high res and you get more decent image). What do you think? I used one of those but not for electronics but for small friction pairs in mechanics and worked out pretty well

@@Zaniahiononzenbei I mean you can pay more for high resolution and macro lenses. The thermal camera at my work can identify individual hot 0402s with ease.

Wait so that's not what was happening???

@@KendallHall nah the only thing taking fat dab hits here is that Mobo there with all that Rosin. Shit tho I needa get on that Mobo's level.

@@robertg8996 I think it's not actual THC bro 🤣🤣

@@TheTicassShow lmao I know bro it was a joke 😂 Edit: shit tho Rosin, Resin, same thing really 🤷

"THC dab" reading that hurt my soul

All hail the algo

Are you trying to say your a pothead? Or do you like electronics repair?

@@DM-uk3dp I would go with the joke and not the actual electronic fault finding

The algorithm just really like you.

In this case it was a capacitor, they are the most faulty parts in any circuit i believe. Changing it should do the trick

@@kcalbxof not very likely, SMD capacitors are extremely reliable, this one might be getting shorted and overheating due to another more complex and power hungry device such as an IC being actually shorted.

@@TuxraGamer nah, smd ceramic caps can crack and short between their layers

@@TuxraGamer i was RMA solderer and ive resoldered many connections on SMD resistors and replaced them frequently. Mainly videowalls. Problem is, depending on the product they go through many heat cycles and the consensus seems to be that these connections start cracking, raising the resistance/fudging everything up. Thats why most times just adding more solder (mass production uses lead free, brittle solder) fixes such issues :)

​@TuxraGamer if that's the case you will still see a short or low impedance across the pads of where the cap used to be. Most of the time, it's failed caps.

Не, там по ходу грязь между ними была. Это она вылезла. Но все равно вандально снимал упираясь в чип.

Там компаунд все будет работать

​@@useRrrrrr2022какой компаунд, там конкретно взял и глупо сколол кристалл. Тут смотря как трещина пошла, скорее всего уже труп.

@@denisyegorov5109 Да покрошил немного, верхний слой - не фатально. Работать будет. "погрыз" немного пластиковый корпус. Но снял да, вандально, не прогрел как следует... Во времена когда процессоры для компа были с открытыми кристаллами для настольных ПК, криворукие сборщики буквально откалывали уголки у кристаллов, и ничего работало. Там главное что-бы нижний слой кристалла не был задет, там в очень тонком слое вся логика чипа, а вся остальная масса чипа 99.99% просто болванка для теплоотвода и как основа для формирования схемы.

So disgusting wtf lol

Lol I did not know that myself

Thats a rosin flux

anjay ketemu adrian

True true.

Wise

I definitely agree with you even though I don't know anything about it. Because you sound wise and this is the internet.

You sound smart and that sounds natural. I agree

I'm tech nerd but I don't know much about the nitty gritty as u present, so correct if I'm wrong but maybe it doesn't affect phone boards in the same way since they may be dealing with smaller voltages? (Only my speculation)

That seems like the better choice because your going to have to clean the thing after the rosin anyway, probably with alcohol

@@ImBUNT you right

Most alcohols you can buy have some water in them. It's best not to apply power to a wet board. It's also a flamible liquid on a board with a short circuit that's about to have powered probes touched to it...

@@charmio I'm pretty sure there's no water mixed with alcohol(I'm talking about rubbing alcohol/Isopropyl) but I could be wrong. Also, it's a phone/laptop motherboard and the highest voltages there would be around 30, so no sparks to ignite. Besides, I've seen this trick on Louis Rossmann, he said it worked just fine if you couldn't afford a Thermal Camera

@@roughshaf7321 True, you're right that IPA is available at 100%. Even so, if left open to air it rapidly absorbs moisture until it reaches an equilibrium of 65% IPA to 35% water. And I do mean rapidly! One study suggested an open container gains 7% water in as little as 15 minutes. You can test your IPA by seeing if it dissolves table salt. I know from experience that you can ignite it with a lab power supply too (I was bored one day). From memory the supply was set at 12v and it took a few sparks but ignited easily enough. The size of the sparks are determined by the current supplied (in practice the important factors are the output capacitance of the supply and the voltage it's set too). If you really want to use this technique then I'd recommend connecting power first and then spraying the alcohol. Also set your supply to 0.8v, if you're looking for a short then this is higher than the supply will provide anyway. With that all said, while it can work I wouldn't try this on anything high value.

Underrated comment

Seriously.

Fr fr but this is still really stupid. The board short circuits and gets hot from all the electrons taking a shortcut though the board. He's putting a bunch of rosin on the bored and watching it melt to determine where the hot spots are. Which is weird and not what rosin is for. You could literally do the same shit by just touching it with your fingers or just buy a cheap thermal camera..

@@fission1110 I would rather call it ingenious than stupid, because those Vapes are like five dollars it's definitely cheaper than buying a thermal camera, and he found a new use for two things. Can't really be hating on that can we?

@@AnonMedic I mean I guess. It's a janky solution to a problem where there's already a free janky solution. Touching it with your hand is free, much faster, much more sensitive and doesn't leave your entire bored with sticky residue you have to rinse off with isopropyl after this is done.

@Dat Boii oh... it'll never work on me then.

Its soldering flux I think, you'd probably get super cancer from it

No

@@clayton9136 why not? It's already shorted. Lol

@@NinjaSushi2 No

IPA 100% or thermal gun

@@NinjaSushi2 I have no idea why shorted circuit would change this case. Shorted or not - IPA wouldn't affect this

Thermal imaging implies supplying power to the damaged components a lot longer than this method. This could lead to damaging even more parts in circuit.

I dont think the pads on the logic board lifted tho

Nah, not even close you can still see the solder still on the traces. I can maybe guess and see why he thought that happened, it's just the water proofing epoxy he didn't bother to scrape off. If the pads were gone it be like a whatever color the layers of fiberglass were so a black spot or if it was a multilevel board even show it'll show copper.

That component looks like a capacitor.

and then lighten your wallet by $500

@@ariewijaya1679 get a seek thermal camera and app system. It's much cheaper.

the cheap thermal cam is waste of money because the low res lepton sensor

@@ariewijaya1679 works for me. You don't need high res. Just find the hot spots or components along with troubleshooting. And an open mind.

@@ariewijaya1679 just to add .. i am nothing against this fancy smoke and magical melt .. just that its messy and possessing such equipment and inhaling rosin smoke is very shady topic ;) ...

Flir cams are a few hundred dollars, rosin and a heater rod are a lot less expensive.

Flir cam is cheap??? Who is ur math teacher ? Plz let us know...

Since when are flir cameras cheap? Are you looking at Wish knockoffs?

Flir Cameras cost hundreds of dollars, do you think it's cheap ? Alcohol trick also will do the job fine but method on the video makes it even easier.

Way better than the 'ouchy' test.

@@Aethelbeorn I dunno. Sometimes you need that reminder that your alive.

Can you elaborate what he using and what is the device that he use to make it smoke?

@DragonHorze You can get 90-99% alcohol for a few dollars at your local store or even gas station, so the difference is quite allot. The cheaper price as well as it's massive availability still make it the better product for the job, not to mention it's use to clean up flux off boards so every board repair specialist already has it on his/her workstation.

@DragonHorze If you like that effect, there is also compressed air in a can. Freezes the area making it super easy to find. But at the end of the day it's up to you.

@@czpanama So you want to start building up condensation on your board when you power it up while looking for a short... Might find a couple.

@@tynewlin Hundred of experts use these products in the field. Most canned is specifically marketed to use with electronics, and alcohol does not cause shorts, it exposed them. It also breaks down and clean stuff that can cause short, and dries instantly.

@@czpanama They don't intend for you to create a layer of ice and then melting it directly on live circuits.

Реально

В чем причина, можете объяснить незнающему

@@Otkisylin при снятии конденсатора повредил чип пинцетом

Pipe of crack? That’s a battery

So that's what huntar used to detect shorts.

Yea everything is going to electric.

Ты оказался настолько же умней других, насколько тепловизор дешевле этого инструмента. Согласись.

​@@vladimirguboglo4017 противник убит наповал, лаконичней невозможно

Yea it bugged me too. What he did was coat everything with a film of rosin. Then he applied voltage to the device and then it smoked where the short was. Look for the arrow. My only problem is that it leaves your board a hot sticky mess.

I was about to write say same thing

What part don't you understand? 1) Was looking for a short circuit. 2) Was working on a circuit board. 3) Applied a layer of rosin to circuit board. 4) Supplied the board with power and the short created heat, subsequently melting the rosin and giving away the location of the short circuit. 5) The culprit was a surface mount fuse.

just wanted to know how much voltage is injected

Что происходит, я не понял.. Напряжение дал и разрыв нагрелся? А почему отбалды напругу кинул

И площадку сорвал и кристалл сколол. Но это видимо для демонстрации )

Тем временем люди которые обзванивают всю плату чтобы не спалить что-то ещё кроме резистора .

Да не вопрос

Почему?
