If you sent it back to the company for repair they'd probably go like "we have to replace the whole board, that will be $1k, thank you". And that's assuming they'd even bother doing board level repairs.

U shouldnt cry at a company for doing this, its their right to not focus on microsoldering repair, its totally different to manufacturing. U should cry at a company for actively blocking 3rd party repair, like blocking chip or component supply or locking parts in the device by software.

no company repairs such things, because it's unprofitable. looking for a broken component and hiring a technician would cost the same as a new motherboard.

I fix alot of things myself, not at the level Alex do, but i do try :D and i am also lucky more times then not. One of the things i hate the most is the disassemble, there is always plastic tabs that break so easy, a hidden screw under some tape or other stuff you first notice when you almost broke the pcb or something else.. and cables you need to disconnect for some lcd screen or something.. To me the disassemble is just as hard as the fix, not always of cause, but sometimes you fight with the damn disassemble for 30+ mins just to replace a stupid fuse you couldnt access without the disassemble.. So even i am sure some people see Big Boss as just a cool name for the low end easy job, i feel it isnt always easy. For sure a nice team :D

there are very few people who share what they know with people by telling them like you, and teach electronics! thanks to you, we have learned a lot and we are learning that you are well, thank you so much.

Nice video Alex.The machine in the photo looked much smaller and i thought 1500 was a lot,but in business it's really about doing the job better and faster.That machine certainly does that.Then when i saw the real one ,i thought heck no wonder it cost a lot it's BIG and heavy with a lot more components to it.That means it also has encoders to measure the tape length and if it starts giving you odd length tape pieces it would be the disc that goes through the sensor has got tape fuss on it.We had one where i worked that i fixed but a different brand and smaller.big boss has a great memory.

As soon as I saw the relay, then that was a pretty good place to start as the machine was clicking...good job.

Driving dc inductive loads like this motor causes decent back emf across the contacts of small relays when they open off causing them to wear out really easily. If you put a flyback diode from negative to positive on the output to the motor, you will get a few more years out of if before it wears out again. Love the videos by the way!

I highly doubt that isn’t already populated on the board. It would potentially kill other components on the same power rail, which would happen mostly under warranty since it’s not an exposure failure. No company wants that.

I've been in this situation when my tv broken. Fuse keep blow if replace with new fuse. Search for power supply board so expensive online. Replace 3$ triacs that faulty fix it. My first repair attempt successful. So glad😂

Thank you Big Boss for reassembly, and thanks Alex for fixing that relay.

Alex, you made Alex a very happy customer. Dont forget to leave a 5 star review for your self :) Salam from Denmark to you, Big Boss and your family.

"Thank me!" 🤣🤣🤣🤣 I always learn when I watch. This time I learned that low melt solder stays soft for up to 10 seconds. I also learned that low melt solder gets brittle. These are good things for me to know. Thanks Alex.

Fixing Electronics requires so many skill-sets including the Art of soldering. It's not something that would lend itself to the employment of apprentices. You gotta hit-the-ground-running when you start doing it and have a firm base of electronics theory and practical soldering skills already. It's not for everyone. I'm so glad you are the expert....lol

Great job on the repair.

Oh man I love watching you fix things!! I always thought of something broke in your office or home, you could fix it. Like, anything!! Big thumbs up matey from Australia 🇦🇺

If sometimes you hear clicks and sometimes you don't, a relay is the first place to look. But I guess it was a shot in the dark in the sense that he didn't actually test anything, and the problem could be in the circuit that controlled the relay, and not the relay itself.

14:10 Hi Alex, Have been enjoying your videos of the incredible microscopic work you do, and am looking forward to when you do a video on steadying your hand whilst working.

Great video, I loved the showcase of that tape machine "whoa it can :o" . Nice to see it repaired lol

OMG this is crazy such a great stuff I've never heard about this before.

Yes please,Alex, do the video on how to help prevent our hands from shaking! Also, very nice fix on that expensive dispenser!

The relay probably drives the motor. A trick used on car points was to put a capacitor across the points to stop arcing and make the relay last longer. Another trick is to put a 12 volt zener in series with relay driver fly back diode to make relay turn off faster.

well done and what an amazing repair! :D

+1 for the steady hands technique! Help me Alex 😶🤣

Nice fix.👍

Amazing thanx bro وشكرا بالعربي أخوك من الجزائر

Now they'll start sending in tape dispensers for you to fix!👍🤠

Awesome job

you guys are life savers

The contacts on the relay just gets a layer of carbon on them over time. You could even pull it apart and clean them carefully and it will still work unless the coil itself is burned out. The contacts have a layer of silver plated on them and are quite robust, but as mentioned before, the carbon builds up each time the contacts make due to the smallest arc.

@synony6

Жыл бұрын

It's worse when they open on dc inductive loads due to back emf. Mentioned it earlier but flyback diodes drastically reduce it and increase the lifespan of the relay. We used to change relays every year in a factory that had a lot of relays driving solenoids. You could see the huge blue arcs when they were opening off. I went through and put diodes on them all and almost completely stopped the arcing across the contacts.

Great work! Would love to see steady hand techniques, since I can always bring helping hands tool!

Its nice that the relay was available to buy, I had to repair my electric stove since one of the "temperature control" (clicks on and off every time the temperature is exceeded) relays burned after 10 years and that relay was not available at any distributor at all (which would be nice since I can get authentic parts really fast trough my university), not even local ebay. I was a bit lucky that there were new old stock ones from china but since I needed them fast I accidentaly brought NC instead of NO relays Not a big problem tough, the power gets turned on by another relay so I resorted to a quick hack with a mosfet in the signal line from the microcontroller (to invert it), works a treat :)

I think the original fault was a dry joint on the first solder point you showed at 4mins 21 sec. It had the crusty rough edges you find on dry joints, and these are familiar to TV engineers of the recent past where a lot of heat is generated in the joint due to the high currents in power supplies. I always look for the black ring around the solder joint using a magnifying glass, followed by a reflow. This usually resolves the problem. Perhaps you agree?

I tell you big tech companies one thing. If you ever sell one of your devices to Northridge fix you won't make any money with repairs on it. Mighty Alex will not go to sleep until he has fixed (and made it better than factory).

I use to fix those all the time... FYI use Dawn Dish washing liquid to clean the tank brushes use the PINK DAWN

Excellent

steady hands lean on the table

يعطيك العافيه انت مبدع

I used to have steady hands and was able to solder very well. Unfortunately now they shake to a varying degree, so any tips on how to stop them doing so would be very much appreciated. Thanks Alex for these informative videos.

There good machines we use them at work for the tape for boxes we just replace the PCB when it fails as not worth the time of trying to diagnose the issue to the company using the serial port at the back you can also have it linked to automatically dispense tape required.

Good job

Alex you are the best 💪

The boss is happy that he saved hundreths of dollars thanks to his emplyee's skills

Looking forward to for the video about steady hands

Got it working. Ultimate goal achieved/

The first time a customer didn’t write a note of what happened to the machine and no invoice was sent as well

we have similar machines in warehouse were we work and the tape is super strong if you want to rip it apart

Way to go nice save 😁😁👍👍

Can't be certain but it looked like there were dry joints on the relay coil pins - the ones near the edge of the board. Would explain the intermittent nature of the problem. Would also mean it worked fine after the new relay was in because of the now 'better than factory' joints 😀

Great video as always but today with a personal flare!

In business, you have to keep the profits from going out the door in such matters as repair of equipment just like you did. I've repaired many home appliances just by first looking up anything showing how to diagnose and then possible troubleshooting. Before the internet, I would go to book stores looking for "how to fix" books. Reader's Digest came out with such a library back in the 80's with very detailed books with good photos on how to fix pretty much anything. From there I bought tools like multi-meters and specific hand tools needed for whatever I was working on. I leaned how to do preventive maintenance on many of my home appliances to keep them up and efficient. I had a washing machine for over 15 years and a dryer even longer. Once you take apart a washer, you see things like mildew buildup under the tub rim and dryers full of lint that could cause a fire. I'd usually do preventive maintenance once a year on these and then do things like oil motors on my microwave or the HVAC motors. Cleaning the AC coils inside and out keeping them efficient and the filters cleaned every few months. Even door hinges and handles need oiling. And before you have a plumbing back up, take the traps apart and clean them. Facet washers and o rings will last about a year so replace them also. Waiting till things get so bad that they don't work any more will end up costing you money, time and inconvenience. One thing that can turn disastrous is the hot water side inlet hose that has about a 2 or 3 year life span. It is always under pressure and when it breaks, and you're not home, well, you can imagine the grade of destruction. IN any new house I've ever owned I've kept a maintenance book on all the different appliance and things like hot water heater or HVAC systems along with the regular things like can opener and more. This way I know the age of the appliance and the maintenance schedule on it. It will tell me the reliability of certain brands of appliances etc so I know if I'm getting my money's worth. I see now that there are these home insurance services for such things but they only payoff when the appliance goes critical and there are loop holes that they use to either get out of it or cancel the services. You don't have to be an engineer to do these simple maintenance and repair tasks. The internet has put everything right there for you. Just make sure that you look at many repair videos so that you can see all the other people's ideas and techniques. There are some on the internet that are just idiots and will cause you more problems so check out as many as you can stand to see how many jive with the same successful technique. Approach any and all for the first time with caution and go slowly. Don't guess but use common sense and good instruction. IF you've never touched anything electrical then get basic with learning from the beginning. I can remember when electricity was such a mystery to me. Yeah, I've been shocked a few times but nothing bad. Electricity is to be respected and to keep cautions when dealing with it. I remember hooking up my first live power cable to a house weather-head but I was on a fiberglass ladder so basically I was not conductive or grounded. Stripping the live wire coating and sliding on the crimp-able sleeves And then using the big metal crimpers. It was scary but at the same time I knew as long as I touched nothing conductive or grounding that I was safe. IF you think electricians never get electrocuted, you would be wrong, It happens all the time.

happy fathers day alex

These also have a little magnet on the side of the top hatch/cover so the machine will not work if the lid is open. These magnets also like to fall out but you could short the 2 pins of the sensor on the board so the machine will work again.

Awesome ✌🏻✌🏻✌🏻

عاشت ايدك كلش مفيده الفيديوهات

Nice informative video again. Thank you. What do you think about solder with a flux core. Good or bad? And could you do a comparisons about those solder suckers you used and the ones with a vacuum pump attached. Thanks and keep up the good work👍

Fine trouble shooting Alex and happy fathers day to you

You're gonna be sent these now. 😁

Big Boss to the rescue he knows exactly where all the connectors go , better than factory reassembly AAA ++++

for tht components solder sucker with silicone hose at the tip like engineer ss-02 are better, you can put it right on the tip of your soldering iron while heating up the joint and create a seal to the pcb. they suck up solder much easier then the ones with ceramic tip.

Big boss enjoys the moment of truth 😂, حلو حلو حلو

Don't dispose, reduce and reuse lol. glad it was an easy fix but a relay that small running for 5 years sure could poop itself, good thing it didn't take anything with it 😂. Nice fix and good to see your back in packing business.

Wait! was that a solder sucker??? Great repair! Paper tape is way more awesome than that clear junk. As a know-it-all side note. With clear tape everyone uses 2" wide, which is not made for hand taping. even though everyone uses it. 2" is for automated taping systems. for hand taping you are supposed to use 3". But paper tape is far superior.

That tape is actually glue tape. It's 10 X better because it soaks the glue into the cardboard for a perminent bond instead of adhesive which just sticks to the surface and can fail.👍👍

HAPPY FATHERS DAY BIG BOSS AND ALEX!! Years of experience is what I see. Great job!! Can’t wait to see your new version of the microscope. Maybe Big Boss could have a disassembly video on disassembling something. Would love to learn from 2 great minds❤

hand shake video would be fine,great one btw

From now on the music is the assembly tune !

I can understand that tape being more resistant than your average packing tape (since the glue soaks into the cardboard), but I've seen packers use (good) tape dispenser guns, and it literally takes them less than 2 seconds to do each side (3 to 5 seconds per box, tops), so I really don't think that's _faster._ Probably more secure (assuming you can't get the same type of reinforced tape in a roll that fits dispenser guns - it would be tricky to use wet tape for that), but I can't see it being faster.

I would love some steady hand techniques. I shake like a leaf sometimes under the microscope.

It's clear to see the original relais has a cold solder joint (top right pin at 4:03) I think this was the problem not the relais.

Amazing 😮of

I have had good luck fixing appliances like dehumidifiers and refrigerators. They way the board is designed, it feels like you are working on a device like that.

Better than factory!!!

it looks like one of the relais coil solder joints where cracked i see similar problems every day working on german dishwasher / Washing machines and its 95% a fix with just solder all solder joints of those relais again

I bet the customer was happy with this repair lol

Before you replace the relay... I thing the top left solder seems a bit off ???

Get that man some powered screwdrivers lol

For that kind of solder joints, better use dessoldering gun station than hand pump. With this tool, taking out such kind of relay is a matter of seconds.
