Microsoldering 101: Water Damage and Corrosion 

This lady is unbelievably professional and articulate.

If a customer asks me what brand ultrasonic cleaner I am using and whether I am taking the shields off, I would be politely sending them off to a shop I hate for that customer to become THEIR nightmare.

my mate used to regularly dunk his nokia 3310 into beer. damn thing was indestructible...

This series is awesome, made me buy a hot air station and pratice on my old waterdamaged ipod. Managed to repair the backlight and resoldered some components for practice, still works ;)

For those of us that were wondering about the "filter". It seems to be an inductor. I had to look it up, but it's to block any ac or ripple, supposedly.

I like her as my RU-vid teacher! She's very professional and transparent

This lady is unbelievably professional wow.

Jessa... eres super inteligente y dedicas tu tiempo a explicar de lo mejor ..TK

Love all these videos, could watch stuff like this every day! Thanks!

$800 ultrasonic cleaner and $60 for the multi meter? right that the way to go! thanks thought there is some good point in this video

Why is he always interrupting her?

loving the 'no rabbit holes' shirt :D

This video helped me repair my Bluetooth headphones! Thank you so much Very informative

This is good advice. My brother has a Mk2 Audi TTs with the Bose sound system and they ALL suffer from water damage that comes in from an unsealed body panel. Thanks Audi for not stepping up and taking ownership of your poor workmanship. I'm going to open it up and attempt to clean off the corrosion if it isn't beyond DIY repair. Then apply conformal coating and seal the gap Audi should have done at the factory.

host needs to learn how to host instead of trying to nerd at the same level or out nerd. A good host asks questions to draw out a rephrasing/reiteration of the presenters points, allow the presenter to naturally expand the subject or detail a fine point/confirm their understanding with a paraphrase in a question tone "so you're saying x and y cause z?". This dude just interrupts with "I KNOw THIS STUFF TOO"(but he clearly has a limited understanding in comparison) and on top of that his voice is so meek, muddy and unintelligible in comparison... even if he were to have had a deeper knowledge on anything, Id bet 9 out of 10 people would still prefer her explanation

Great video, but it made me cringe to watch the host constantly interrupt the guest and constantly try to show that he knows as much as her. Painful to watch.

I would get a lot of salt and alkali corrosion around the battery(ies). I had about $800,000 in test equipment on a rooftop when a fast moving violent storm dumped 2" of rain on me in about 15 minutes. I managed to get everything working again. We still had access to trich back then, and the facility had a UPW (DI) water supply. All I had to do was bring my own ultrasonic cleaner to work. They had the UPW, microscopes, testers and trich in house. This was back when thermal imaging cameras were around $140,000, plus you wore a battery belt, and we had Dranetz, Q factor, and variable load cells, on the roof. When there is lightning everywhere, that million dollars of stuff on the roof is expendable, compared to the manpower. Rip out the test leads, close the equipment panel doors, if something will fit inside the cab, throw it in, and evacuate that rooftop ASAP. 1 death and that facility is shut down for 1-3 days. One outage 30 of minutes into a process, and that can cost $8M to the facility, so that $800K of equipment is expendable, and it can usually be repaired. I don't climb around on rooftops, or fan attics or interstitials, and do tool installs, power management assessments, and preventative maintenance. I am too old and beat up for that now. I am in my own shop doing similar repairs, indoors, (most of the time). If the traces lift off a board, I can rebond them. I too have the Hakko hot air station, and the $2000 German Weller, and a Ramsey RFI glove box, and I have used ultrasonic for many years. The little German tips from Weller will spoon in tiny bits of solder on those FUBAR SMD components and the chip terminals. What is it? A $600 cell phone or a $60,000 thermal imaging camera, or a $600,000 O Scope with extra RADAR or DDR modules? A good $6000-$12,000 LCR pays for itself very quickly. You can run through and check caps in circuit, and it just save so much time. I try to stay away from the smart phones and video games. That is what it is, and there lots of competition. I have my ham license, and that is one element of my work. The rest is audio amplification, and guitars. Those are the bread and butter, and the gravy is test equipment repairs. Sometimes it's pretty nasty gravy.

Never really under stood the use of the shields, that's really cool makes a lot more sense than heat or whatever I thought they were there before

This video has been amazing thank you so much

what is that liquid she used in the small bottle please?

How often would you recommend changing the solution in the ultrasonic cleaner?

Im a definite new subscriber. This micro soldering series was excellent and greatly appreciated.

This is incredibly indepth! neat

Will someone please slap the dude shut. Let the woman speak man!

the moving electrons speed up the process of oxidation resulting corrosion

I'm wondering if ther is any reason the manufacturer couldn't dip the board in a lacquer or polly to protect them or do they need to like breath or something ? Obviously I'd need to a non conductive material

ok , i just loved this series of video !!

Awesome video. Is there a ultrasonic cleaner what you can recommend wich is smaller then the CP500D. Just for small boards?

Excellent. More of this stuff

Can you stop interrupting her geesh

So I tried charging my iPhone 11 while it was dead and still wet, does that mean its fixable?

Awesome, great learning

Hi, great video Please advise i swan with my iphone 7 plus at the beach and it had a very bad corrosion. Iv taken it to two techs and they said it cant be fixed. Is there so other way i could at least get my information on the phone? Please help

Awesome demo. I. Would like to know where I can. I find someone to do this for me to clean a circuit board that got water damage.Where or how would. I find this kind of business. Thanks for any information u could give me. You guys really are awesome.

Is electronics contact cleaner able to remove water corrosion from laptop pcb ribbon cable socket? Is Cyclo electronics contact cleaner any good for removing water corrosion?

this started like a nice video but after hearing YOU KNOW for like 30 times in a row i just couldn't watch any longer... shame really :S

Very informative and interesting. Thanks!

My question is once you remove the shields; how to put them back on? Solder?

What about flux and heat gun?

You you resolder the shields back onto the board or leave them off?

Great video! Do you have an update on a consumer version cleaner that someone could try at home for a reasonable price? Cheap Cricket phone. Just trying to get the pictures off of it.

How much does a shop usually charge for this? Why are people saying its not worth it from a business owner point of view?

great information

Should all ribbon cables be removed from the boards prior to immersing in a cleaner bath. I have a drone and the ribbon pin connectors have been exposed to the water . It would be pointless cleaning the board if I have to replace the ribbons (8 in all)

I am glad my Moto G had an internal waterproof coating, I had a case on it and dropped it in like water of 50cm depth and it survived and then dropped it in a muddy puddle hiking, and it survived. Of course it's dead now from an OTA, the last thing I expected to kill it.

Started repairing 4s, overkill cleaner shook half of the components off the board, at the end a 5c was shown working..... ESD is a myth ?

hi friends. is it possible to have water damange just by living close to the sea? to be more specific. my 2015 macbook pro died in 2018. tec guy said it was water damange. can it be possible? is yes. what can i do to prevent this kind of corrosion?

Where do you get the parts from ? is there schematics for these boards ?

@20:45..uhhh 🙈 did she just brush off part of the circuit board lol ??

Hola .. como se llama el instrumento en el que colocas la placa para desoldar los blindajes? ... ese que es una especie de tubo con una rosca en su parte superior? ... MGracias !

I looked at the Crest ultrasonic cleaners and they carry various sizes rangeing from .5 gallon to 7 gallons. my work would be on cellular phones. what is your recommendation

Hello Jessa, Thank you for these great tutorials! Having some trouble pinning down the problem and would like to trouble you, if it's okay, for help and some insight. WHAT: LGMP260 THE PROBLEM: Washing machine then in the dryer. No reaction to a battery or to being plugged in to the all. WHAT I HAVE DONE: Allowed to dry. Took a part down to the board and cleaned out with alcohol. All board components look just fine. TROUBLE SHOOTING: Multimeter - the leads in the battery bay produce 0.01 volts (between + and -). The continuity between between the usb charging port and the battery bay leads are 6 - 36 and there resistance was @3 to @23 ohms. Thank you for your time!

Talking about phone in salt water, i worked for sea trek helmet at doctors cave beach mobay jamaica, omg i saved so many phones that accidentally fell in the salt water,,,first thing i did was to remove battery and dump in fresh water,blow dry with scuba tank then pulled it apart give as good as i can an alcohol cleaning then leave in the sun as long as posible then reassemble, works every time escept from semens phone they seemed to always burn out as soon as they 2 feet of salt water,

does the orientation of the replacement caps matter?

how do you open it

please show me all board cleaning tools !

It's second movie with soldering with Jessa Jones i watched and there is no soldering.

Guest star Louis next !

Need a great place to recover my texts from a salt water damaged ZTE ZMAX Vero Beach FL Ty in advance

Good

They need to redo this video, love Jessa but man, fire the host.

No Rabbit Holes, i understand that

should you not wear a wristband anti static while handling the board?

moving electrons

What is the liquid into ultrasonic cleaner?

So sad that Apple hates this womans company. They have defamed her great work.

Here's the easy solution. Get a warranty, save your stuff on the cloud.

What model of Crest was that?

If practical, given the availability of distilled water, wouldn't it be best to open a phone, and dunk/rinse it in that first while it was still wet (after depowering it), then dunk it in alcohol? The clean water would help dissolve and wash away corrosive minerals before they can corrode anything. Alcohol alone will only absorb and evaporate the water; it won't necessarily keep mineral contaminants in solution and away from the metals and solder. In fact, the alcohol alone might exacerbate things by concentrating and accelerating mineral deposition.

“You know, you know… You know!” Lady… We don’t “know”! That’s why we’re watching your video.

"You know.. you know... you know... you know" But good video thou!

less talking more doing

Distilled water NO!! The salts comes from the corroding metal in the pins. So it will be conducting after a short while! Isopropyl alcohol is a winner, Secondly, disassemble it as much as possible put it in an oven at 45C (if you cant remove the battery) otherwise 60C for 4-5 hours. This works very well.

btw i saw mona lisa in left filter 28:16 left side of middle filter

Rice works fine if the phone is a little bit of time in water. Also how do take apart phones that have no lids.

Horrible technique to take off shields .. never do it an the sides always o top of it and never fold it

There's no bigger model of the CP500 swallowing ATX motherboards and full-size keyboards? With all due respect of the CP500, $850 for something that can only take the smallest stuff is quite a bit... pricey.

what does she mean with no rabit hole? around 15:00

I have a Samsung S5. What the hell is "water damage?" ;)

omni device how do I find this!

Hey I wanted to fix my water damaged iPhone and after going through the process - no success

interruption corruption dude !!

wait.. did she dropped HIS PERSONAL phone into the water xD?

90% alcohol is best? Can 70% work as well?

The iPhone SE has a motherboard that is immune to liquid

I like Jessa a lot, but this dude is so annoying. This is so painful to watch.

Вот бы весь этот ролик да на русском языке - ему бы не было цены.

i had 2 phones that both fell into the water, out of my pocket (i was fishing) and they both survived :D

Think about it.. ...Ummmmmm.....you guys are somewhat incorrect when your showing us the board and saying " Look at all this corrosion." It was dropped in salt water right? Well majority of that mess is dried salt,not corrosion. Not saying there's no corrosion there or that it did not corrode. What I am saying is the majority of what you're looking at is dried salt and some corrosion.

The rice thing does work, somehow it works like silica packets. But like you said it depends on how severe the water damage is.

Someone tell this guy to get off the redbull or coffee. DONT DO THE DRUGS!

repair not successful?

"de-soderring" :D :D :D Always makes me laugh how the Americans insist on a silent L in S O L D E R :D :D :D

Why then they wont sel it whit simple plastic bag, even food has it. dont by shit products or not by at all.

Stop saying ye no yeno

I'm sure that is not right to put the battery with the board in any kind of liquid be careful

You explained totally wrong how ultrasonic bath works, it doesn't matter the resonance with components. The different sound waves reacting different in fluid at different frequencies , so the liquid can make pressure to liquid for small components.It is like tiny points of pressure in liquid that allow it to find the smallest places on components to wash them. It create sort of high pressure waves. sort of jets with pressure. They have nothing to do with the resonance of the board components.

Solution don't drop your stuff in water! Also don't buy Apple!

The omni vice? This video keeps getting more and more rediculous. Why cant they just call it a plate vice? That's what it is. A vice with two little plates. It's more like a clamp if you ask me, a vice belongs in a garage or a gunsmith cabinet. This may be the dorkiest video of all time

for 200 euro phone they need to do that for free. not my problem that they sell bad quality pruducts, if you sell shit then repai it forr free.
