Thanks again Sorin! I will get proper calibrated coffee so I pay more attention with the + / - wires 😳I'm turning this into a backpack pc used with AR glasses so I can work in nature (with tiny screens in front of my eyeballs). Once it's done I'll share the video of it here in case anyone's interested.
Sorin, not every moment is "say hallo to my little friend", you have to be gentle sometimes to solder things back in place hahah you're awesome great job!!
This was a proper calibrated video! ...As always, this was an awesome repair! Thank you Sorin for always sharing your knowledge with the World! You Rock!
In Romania, o numeam protectie "antiprost". Sciu in romana doar pentru Sorin, sa nu se interpreteze pentru altii ca o jignire, dar asa o numeam inainte de 1990
Much Thanks for another great repair Sorin. For anyone wondering it seems to be an Intel NUC 12/13th Gen motherboard just fitted into a Custom Akasa Turing AC Pro Compact Fanless 12/13th Gen NUC Chassis/Heatsink.
@@tim0steele you are right there was no need for hot air to replace this diode, any time a component can be soldered using solder iron then do it safer for the board and the component. for myself when I unsolder bios chip or mosfet I solder it back using my solder iron for a strong solder bonding and less heat to the board , also to avoid of flying small component like resistors . I learned my lesson when I was using just hot air for everything till the moment I was soldering back bios chip and very tiny small smd resistor with unknown value flown off the board . spent like 3 hours trying to figure what value was it from searching online for schematic to test random laptops boards I have. laptop worked fine but it really was unneeded troubles because my laziness to use soldering iron instead of hot air.
To be honest it's fine if we replace that diode with M7 but it should be replaced only with diodes that are used at input side like dell hp laptops etc. I mean it works fine but Sorin has a lot of scrap boards so why not. As always if a proper calibrated fuse works it works 👍 He is one who is trying to explain people electronics not like youtubers giving schematics and assembling. Keep it going Sorin👍
Hi sorin , the model that you have repaired it's a Fanless Intel NUC 13 Pro, Core i7 12-Core PC, Fast SSD, up to 64GB DDR4, up to 4 Displays , and cost about 1.153 Euros Vat included. A nice and powerfull pc. Great repair anyway
Nice repair as always ! Sorin, While soldering the diode using hotair, a blob of solder escaped and is hidden at the hdmi port next to the 2 arrows ! its at 10.20 ---10.23 :)
Just to say: Sorin, you didn't test the donor diode. With low probability it could have been broken too (infinite resistence) and you would not notice the difference. Only the customer would have a burned board if he connects the wrong way again. Also, the south side of the small diode above didn't look convinigly soldered. Why using air and not just the soldering iron? I would have preferred the iron.
Akasa Turing A50 MKII heatsink is the type of NUC case here. You can buy a different model heatsink / case for AMD or Intel NUC board. It's a proper heavy piece of kit to cool the NUC's. These cases are not cheap :)
10:20 look at the top right, on that small innocent solderball, which is trying to hide behind the corner, escaping from the Sorin's tornado air, which blew away from the surface that small poor diode on the left, haha What a horror movie on the motherboard 🤣
Hi Sorin, nice Mini PC and you luky Intel decide to protect his product... good every time recording your work so can recovery from error like disoldered diode.... thank for this video for us subscriber.... se you bext video... best regard Francesco timpano from Florence Italy
this guy is amazing in finding faults BUT when it comes to soldering back he doesn't care much to clean the pads for the new component ..or adding new solder ...like in this case he used liquid solder which low the melting temperature and he didn't even care to clean that before soldering the diode again ...i hope he can do much better next time
Even this one will work as polarity protection. I really doubt that NUC PSU have problem with voltage spikes and TVS is absolutely needed. It'd be better but then again this is better than nothing.
Yeah been thinking the same thing. Doing that on anything Win7 or below will destroy the boot and they're a pain to rebuild. Win 10+ isn't too bad. In that if it breaks it will make a decent attempt at fixing itself and the user likely won't even know. Still, never shut down a machine mid boot. If you want to pull the power out then do it once it's booted. Less dangerous but still not advised.
There is no such thing at PCBs being laptop or PC. These boards expected DC voltage with correct polarity, reversing it would (without protection) destroy any mosfet in the way (as current would go through parasitic diode inside them and overheat them) and any electrolytic capacitor on that path. Possible even every IC on the board.
These things are powered with an external mains adaptor which provides regulated, polarised, DC output. When DC was applied with the wrong polarity it took out the TVS diode because of the current flowing through the diode. A poorly-designed mains adaptor (no short circuit detection / protection). The diode is (was) primarily to protect against over-voltage / spikes.
A protection diode is good for protecting against reverse polarity mistakes.....but how come more damage didn't occur after it failed short??? Surely with the diode shorted, the circuit was exposed to full reverse polarity at 8 amps...???
nope it is shorted to ground to protect the board . this diode one lead to ground other lead to positive when it short it means positive shorted to negative and the voltage won't go anywhere after that . same as shorted capacitors
If you look at the board layout it has a thick white stripe of where the + of the diode goes on one of the sides. He actually could have used that indicator for the other diode he blew off aswel instead of having to look back at the video.
Those TVS diodes are sometimes too sensitive. Just remove the shorted one. It should be fine. If you have a new TVS diode with a little higher voltage, put a new one. There is no point in putting a 4007 rectifier diode there.
Hi Sorin. Whats the exact model number of the HTi Thermal camera you use ? Anyone to advise me. I really want to buy one like that. Do you have that type on your UK eBay store
I was suprised they put a diode there for protection. Nice of them.
I love Sorin's idea of what is a valid CPU heatsink. An NVMe drive stick of metal is virtually a Peerless Assassin
Proper Heatsink.... We have picture. Dats crazy!!!
0:43 "Let's check the customer email ... 'Hi Sorrin! I think I've breaked my nuke. Can you help? Regards, Kim Jon' "

Is that Mike from the video?
@@Dragunov1111 hi yes it is
where did you buy that one? the all in one giant heatsink design looks cool! good luck with your project!

Good job for the solder tweezers?
Yep! Why the hack did he use the hot air gun!?
Probably a professional defect...
I'd have used a soldering iron to put back the diode.. avoids other things blowing away ;)
Customer did it once, the customer will do it again. The diode must be there.
I would definitely replace the diode, but with a soldering iron not hot air.

Well spotted, I had to watch 3 times to see where you were talking about, it just sneaks along and disappears under that.
I saw it as well right away. Problem is I'm watching it 2 weeks late. Good eye though.
You could have used just solder iron instead of hot air, much easier in that narrow space. And you slightly melted the plastic.
It should have probably been replace with IN4148 or similar so if a big reverse current it can pop.
You're right. High amps doesn't matter, UNLESS there's a short. Then, high amps can cause unnecessarily bad things to happen

we have picture - it's crazy - proper nice motherboard
its working ! We have picture ! after 10 sec . PC shut down xD Priceless !
hi sir,the one which was short is of a high switching speed more than the one you have replaced
anyone sees the solder balls around the connector legs, around minutes 12:00.
is it oke if they keep staying there?
As long as there's no bridges it should be fine. Just cosmetic
Should be fine if it doesn't short anything. But this is why I dont like solder pastes, very hard to clean properly.
5:45 here I am asking why on earth would you pry it out instead of desolder, useless risk to tear up the pad.
Dodgy is the way, could have used iron later as well. The legend lives on
Probably because it was rather obvious that it wont rip, because the leads started breaking off as soon as sorin just moved them to remove the short.
I couldn't help but notice that stray solder ball floating towards a connector
this guy is amazing in finding faults BUT when it comes to soldering back he doesn't care much to clean the pads for the new component ..or adding new solder ...like in this case he used liquid solder which low the melting temperature and he didn't even care to clean that before soldering the diode again ...i hope he can do much better next time
Proper nice job. You forgot to solder one leg of the small diode
Sorin,please tell me u removed that solder ball that went near the ram slot,in rest great job!
Good job mate 👍
Very good!, nice PC and Fix!
Hello🤝good job & nice mini pc 👍👍👍👍👏👏👏👏👋👋👋👋👋
Sorin, please what's the name of the material you place on chips after soldering to cool them down. I need to buy one?
Nice job❤
That should be a TVS protection device such as P6KE27A or so.
Even this one will work as polarity protection. I really doubt that NUC PSU have problem with voltage spikes and TVS is absolutely needed. It'd be better but then again this is better than nothing.
It's fine, that replacement diode will take 1kV before breakdown, ho, ho.
Pls
What can I do if my Advent laptop is always entering setup. Not booting to windows
It can either due to a faulty keyboard, misconfigured legacy/uefi/secure boot in the BIOS!
It's a miracle you still have clients...
I got goosebumps seeing how many times you interrupted the windows boot process...
😅 I've grown accustomed to seeing it here. If I tried that with my clients' PCs I doubt I'd have as much luck as Sorin has lol.

can't wait for the video for tools you use
It's in the video description.
Cool PC...
the pub must be in the first the video for watch all
gj sorin !
Ai uitat o bila de cositor langa portul Hdmi :)
Lol youre solder ram slot and this diode not for protection just 2 amp and low voltage because its schotkky
Add a bulb 💡
USE ss56 diode smd for protection reverse. GOODDAY
gonna be a capacitor. say hello to my little friend!
we have picture that’s crazy
*inverse or inverted :)
I think all the mini PCs are using more powerful mobile processors, so NUC is probably not a thing anymore.
Proper calibrated Diod 🤣🤣 LoooL
So modular!
❤
10:45 😆
Use a proper tip instead and use a solder iron ...
this video show that solder low temp no sense :D

When I hear a "proper calibrated" word I expect a wire
