Next episode of NorthridgeFix with Big Boss on vacation: Fixing a Boeing CH-47 Chinook helicopter, customer came in said he dropped it on the ground and no longer turns on, paid extra for expedited service and wants it done by yesterday
Jokes aside, love these unusual repairs!
For this repair, "better than factory" definitely required.
Great repair and at the end of the day you are educating them and me. They make the world going. We cannot live without them? We all have something to complain in life. Both solder sucker and braid have its application and I use both.
And now ur an appliance repair man. Truly a renaissance man.
Great Video Alex! Strangely enough I recently replaced 4x relays which look identical on a solar inverter repair. I also had to repair a few tracks that were burnt out due to high current flow so I used 2.5mm2 solid copper wire to beef up the tracks. Great Job. Well Done!
After watching all your videos for so long took me awhile to finally decide to fix my Nintendo SP which wasn't charging for years and after my first attempt its finally fixed. :)
Very nice job fixing it and explaining how to fix it.
I agree, low melt solder is the best approach. Having said that the way you're supposed to use the solder sucker is to heat the joint with the soldering iron and once the solder is molten you quickly remove the soldering iron and put the solder sucker fully perpendicular against the board and release it so you're covering the entire hole and pin with the solder extractor. When you do it in that manner it's actually pretty effective.
Agree
And adding more solder is helpful when using solder sucker.
Was gonna write th same
@@requiem4adreamc I sometimes use a toothpick to enlarge the hole in the board while the solder is still hot. Works great.
Agree, sucker is usuable specially when brandNew like that one. But like this bro just said, you must retire tip when using socker
Glad to know you will touch appliance boards. Will keep it in mind.
That type of failure of a soldered joint on a relay or inductor is usually caused by metal fatigue of the solder, due to vibration and lack of mechanical support of the component. I would always put some hot melt glue or similar around the relay to take the vibration stress off of the soldered joints.
How do you know that the old relay failed? It looked to me that the relay pin was burned due to arcing at the failed soldered joint the heat from the arcing would also cause the track to lift from the substrate.
Or excessive current flow, and oxidisation of the solder. I recently replaced 4 identical relays on a solar inverter, and there would have been no vibration in that.
Kap tape at the least.
I think you're confusing the relay with a transformer.
Excellent job as usual 👍👍
Ps because of watching experts like you on UA-cam a couple of years ago I traced a problem on our dishwasher board it also was a relay and I thank you and people like you that share you knowledge with us 👍👍😀
the solder sucker works on the principle of a vacuum. you did not enclose the joint before activating it.
Mashallah brother i love your videos , ive been ona streak for the past 2 days almost watching everything lol much love from north macedonia south east europe
I remember candlewax being used back in the day perhaps for waterproofing too
Hey Alex, Must say that was a "wicked" job!
Clear nail polish makes a great conformal coating to touch things up.
Love your video's man! Hard cleaned my pc today. Because of these video's I had the guts to do it :D
I like it when you save the world from complaints 😂
Pine hollow auto diagnostics gave you a shout out on his Porsche Relay fix today ❤
I'm now confident enough to practise micro soldering
Quite a common fault with power relays, as they age the contacts start to get hot. This leads to thermal expansion and a dry solder joint that starts to arc. Had an inverter in for relay replacement but the arcing had burnt most of the way through the PCB...
I know you said in your video that everybody has their input ! But a coat of clear nail polish is a little trick you can use to “water proof” your work !
Pro Tip with solder suckers. Melt a little extra solder into the location, then suck all that solder out. Solder suckers are not for every situation. They were designed for PTH, that's where they work best. Like everything else, it's a technique and a tool that takes practice.
I just like seeing solder mask being applied because it's kinda cool.
Using solder wire as the connection link is a nice trick that I will have to remember. I say that but my soldering skills and tools are no ware close to yours.
"we got this board 2 days ago,
we ordered the part right away,
we got it the next day,
and now we gonna invoice and mail it back to the customer"
I expected it to end like:
"and now we gonna charge $800 and send it back to the customer" :D
Excellent Work!!!! SINCE I WAS LITTLE, I HAVE LOVED THIS TYPE OF WORK BUT, I HAVE A VERY SHAKEY HAND. IF I KNEW AN EARLIER ONE OF My Sony Bravia KDL-50EX645/SN5412246 needs it board parts replaced. factory defect DPS-162LP ??????
I have fixed so many of those boards. That and the Samsung dryer boards with stuck motor relays.
U should place solder sucker completely on joint to make it work effectivily
I don’t have three hands, LoL that’s good one… yea you did excellent job… Better Than Factory, awesomey work, thank for sharing video, never get bored watch you guys doing those jobs.. I love it… keep it up with video., enjoy watch your show and other.. ;)
Interesting repair. Great fix. Thank you for that video. Greets
Great work!
I worked a lot in ATX PSUs and solder sucker are good at this use. Like any tool ... you have differen qualities .... I used an old tired Goot and worked like a dream. Sometimes you need to add solder. And sometimes you need to be patient on bigger areas, even when solder looks melt is just melted on the surface ... and the sucker end doing a mess. Issue with suckers are, the bad ones tend to clog constantly and lose suction. But even the good ones need to be cleaned frequently to be effective. Of course you can use electric desoldering guns. Again Goot makes great ones ... but the tips are pretty expensive and even an SMD component can clog it pretty bad to the point tha the steel rod that cames to unclog wont do the job. They are for through hole only, specially power devices, or vintage electronics. No much use in an Iphone, it will suck half of phone components !!!! LOL
i hope that some day ...we meet in Person:)
i Love it how you love your job....i can feel it ;)
i do simular....but not these tiny small things.
my best wishes for you and your related :)
Sorry for my poor english;)
It's so funny the people that can't read dry humor 🤣 I love Alex's dry humor 🤣
Two relays were replaced on my oven's PCB due to a power surge caused by a storm.
* The oven was ON during the storm
Also a relay was replaced in my Onkyo stereo amplifier due to the same lightning storm.
* The Onkyo receiver was OFF during the storm.
(** I recommend turning off devices at the breaker electrical panel or unplugging the device during a big storm. Unplugging the devices is sometimes not practical due to the location of the outlet and the number of devices requiring to be unplugged)
Hi,
If you mention temperatures, are they in fahrenheit or celsius?
Hot air 500 degrees and soldering 450 you mentioned in some videos.
Keep up the good work and nice interesting videos.
Best regards,
Ronald
Those are celsius figures.
I laughed at the 100 per pin but in my brain I was kinda hoping it was true lol. I'm too old and crippled to do anything else, now I fall back on my electronics knowledge I got yrs ago and do some work. I got a good education from a top rate school. But getting started is tough, equipment costs money.
Use conformal coating to waterproof the board.
Unless you know what was applied from factory I wouldn't even mind, it's probably coated by deposition with the acrylic type or parylene, some types of conformal coating won't play well together, gotta be careful
Mg Chemicals makes a real good conformal coating in a spray can.
I'm gonna need to order lowmelt after this video
You are Master.
Beautiful work !
this is a dumb question, but what does the solder mask look like from the side-view, is there a noticeable ridge/bump due to the added solder+ material, if that is the case how would you make it flat..?
I can't believe that you have to explain yourself about a previous video you made (spectrometer joke). What a wonderful world.
Beside taht, many thanks for your repair videos, very instructive. Thanks
TBH it didn't look like a joke when he looked online how much the thing cost and that he'll charge accordingly
Those hard tips on the solder sucker are worthless. The one I use has a silicone tubing that you can replace an infinite number of times and it works very well! It allows you to press down and have an almost perfect seal around the soldered pin/iron tip, which removes almost all the solder... at least enough to easily remove the component.
Since most of us are not scientists, I will say... I THINK that is the best use of a solder sucker!
You can waterproof the board by spraying it with clear coat. Couple coats
I remember that you said that 100$ per trace thing, but you also said that you would charge a fifth of what it cost used and that would be around 500$ not 2400$ so I got that you was joking.
I use Nail polish to make pcb water proof for washing machine just saying good job
I would love to learn this craft. Any suggestions? I have access to junk ecms for heavy equipment so plenty of materials to practice with.
Plenty of videos on youtube about it. Just put it in the search box.
Which brand of solder tin does NorthridgeFix use?
The long scratch is funny, because under the microscope it looks like somebody was angry and just lost it, but in 1:1 scale they probably just slipped with a screw driver or something similar :)
Hahaha....I like the ones who don't have any idea and try to tell you how to do it best 🤣 I'm sure the board owner can apply like varnish or the waterproofing marine stuff if need be
you are a funny bugger! love it
Top job as always
wouldnt resin water proof the trace?
Some control board they don't put relay number how you know which part number of the relay
I will not get surprised if he fixes nasa stuff in future. As always great work that was better then factory
First time i saw you using solder sucker..
Wow, you did it.
If you use solder suck on micro solder gonna suck the solder off and the whole part! 😀
Beefing up the trace is what you need to don on appliances with high currents.
Clear nail polish from your wife's supply will work wonders as an enamel conformal coating to aid water resistance.
How dare you try to joke around 😅 🤣
As a appliance repair man iveseen alot of these fail
u actually trolled me hard hahahahahaha well next time i'll not trust u 🤣
I was waiting to see Big Boss reassemble a Whirlpool Dryer.. 🤣🤣
I just recently repaired the exact same board and relay for my daughters dryer, it seems to be a common issue for theses boards due to vibration. Her relay was still good, I just had to add a wire. As always, nice job Alex!
So the relay needs to be glued in place?
It's not vibration it's aging of the contacts, they increase in resistance and get "hot" this causes expansion and stress on the pin nearest to the contact. That's why it's the same pin most of the time.
Solder sucker is an useful tool for bigger THT solder joints. It is very helpful to add some silicone rubber tube onto the tip and let it 1-2 mm longet than the tip. It allows you to put the tip into really sealed contact with the hole without sucking too much air from around the joint. When sealed properly, the sucking efficiency is highly improved.
Dude, thanks for the idea. I will do this! Sounds amazing!
Solder sucker works fine, when you need desolder any tht components, but after sucking solder jonit you need still using solder wick but save them. Solder suckre works better when you mixing unleaded tin with leaded. Regards 🙂
Hi Alex. Great job, but I always wrap the wire around the relay pin. This is how I make a "sub pin hole". Is very handy and also better covers the relay pin. Think of it as a pin hole. Keep making good videos as they are very educational and include various tips and practices. Best regards from Belgium. Andy.
About giving good advices: here in Germany we have a saying for this: "Eine Ameise will einem Adler das Fliegen beibringen." Translated it means, an Ant wants to teach an Eagle how to fly ;-) Good work Alex!!!!
I have been getting into appliance control board repair because of you. It is absolutely wonderful to see your approach to this. A lot of Maytag, Samsung, LG and GE customers I have are thanking me, but they should be thanking you. You are an absolute artisan and I wish you nothing but the best, sir.
I think he made several careers.😂
Solder sucker is good, maybe, it's because you are used to in using the solder wick,I've been fixing electronics for 37 years, using the conventional way, still using the solder sucker, I don't have enough money to be a "high tech" technician, but I always make sure that my costumers are satisfied....,no backjob, Americans are always for the pay....sorry for that.....we are of a different race.....I am proud to say, I am a pure Filipino, and you are, I am sorry, I don't know if you are a true blooded American....✌️...anyway, congratulations, and I admire you for fixing troubles in less than 30 minutes👋👋👋👋......I am one of your subscribers.....🙂
I'd just like to take a moment and thank you for uploading videos over the weekends. Just feels like hanging out with a friend and shooting the breeze for 10-15min each time, even if you cant hear me. Whats your plan for the old scope camera you have sitting on the bench? Backup or another station maybe??
Fun fact copper oxidation is called patina not rust. Rust specifically means iron oxidation. Science lol. Sorry if I am annoying had to.
Don't apologize for being annoying you can't help it.
How is that annoying, it’s a cool fact
I was going to say something along those lines, but I thought might be best not to lol
@@areyouserious3092 How nice of you
Great job saved a dryer from the landfill.
Solder suckers are very effective and quick for removing through-hole components. The problem here was the protective coating. The transparent coating over the board is called "conformal" coating and is available as a spray-on product.
So "Conformal" is what waterproofs the board?
@@daviddenson3324 Plastik 70 by Kontakt Chemie for example.
@@daviddenson3324 Yes
Sucker does a good job if you point it "vertically" right at the joint, not from the side when it just "gasps" air around. I actually have exactly the same kind of sucker.
50 yrs ago I used solder-suckers and the procedure was to quickly remove the iron to fully encapsulate the joint with the nose of the solder-sucker for maximum suck. When I was faced with doing hundreds of through-hole component desolderings, I spent $375 for a de-soldering gun. Best tool purchase that I'm still using today.
Exactly this, even to use a solder sucker it requires technique. Alex didn't use it that well.
"let's work together to save the World from complaints."
Completely agree my friend!!!!! Love the video as always.
Appliance tech here. I do this relay replacement in the field about once a month for these whirlpool dryers. The quickest easiest way was with a Hakko FR-301 desoldering iron, which can also be used to resolder the new relay.
Another note: I've also desoldered that wire connector pin. It happens when you get chatty with your customers.
Which model Whirlpool dryer is this?
Whoa. Using the hakko to actually solder. Of course! (slaps head)
@@Rxke well. The model he is talking about has a pump on it and is in the shape of a gun.. kinda clunky.
I like to use masking tape to hold bigger components like these to the board before soldering them in i hate not having both hands free
Good repair. When using a solder pump / sucker move the iron out of the way and then quickly place the nozzle perpendicular / flat to the PCB.
Ahh yes the teaching an experienced repair tech how to suck eggs.. Classic
Solder suckers are just junk. I’ve tried giving them a fair shake, I really wanted them to work. I’ve tried probably nearly 20 kinds of them. I’ve tried adding extra solder, I’ve tried adjusting the heat from the iron to keep the solder flowed longer, I’ve tried adding extra flux to help the heat remain, I’ve tried putting the sucker perpendicular to the board (which is nearly impossible under microscope). They are just junk. Plain and simple. There are much better methods available. The poster above me is absolutely right, the solder is cooled and hardened before the sucker even becomes perpendicular. But thank you for explaining what the word “perpendicular” means, none of us had any clue 😂
@ProudOfYourRoots definitely takes some crazy fast precision
Those type of suckers don't work very well. The Solderpult by Ersin is better.
It is twice as long and thicker so it sucks more air.
he probably can't be cause the microscope is in the way
I got that telegram reply too :D I just asked him "And who the F*** you are?" :).. then I reported him as spam/unwanted advertisement.
On older audio boards the solder sucker usually rips the traces on the board. I avoid using it.
That's no "motherboard", just an ordinary PCB, or printed circuit board.
(A motherboard is so named because it has daughter boards.)
In my former job, I liked to use a Weller rework station with vacuum pump for desoldering. It was very convenient to use it sometimes, but I wonder how practical and economical this kind of equipment is when it comes to daily use. Alex, have you had any experience with this kind of equipment?
WELLER is a world class maker of soldering equipment. The soldering iron in this video is by Weller. They design tools to be used DAILY, by professionals.
Radio shack used to have a soldering iron with a solder sucker built into the tip.
My Maytag epic dryer basically did the samething.the trace burnt up just from use.
Used some Thick wire to patch the trace,then flooded the trace with solder to beef up the current capacity.
planned obsolescence!!
Every year like clockwork in sept-oct i have to replace the heating element,which is fine as i take the Opportunity to strip down the whole dryer and clean all the lint out.bout every 3 or 4 years i replace the belt,rollers etc. Just keep the parts i need on hand,and order replaces when i do the work.
I refuse to move into a newer dryer as they are a pita to work on,have higher costing parts,and fail more often.
The internet man, it's a numbers game. 1 million people will get the joke, 1000 won't and will email you
I really like your videos I have learned so much from those videos I had business in Libya fixing gaming consoles PCs phones but in war I had accident I stopped working for awhile till I recover .
but I used this time to learn more and thanks to you sharing this knowledge I know and I'm sure that that when I'm back I will be like next level from all I have learned . Much Thanks And keep up the Better Than Factory Work .
Why would you charge 100 dollars for polishing the rings ??
Pro Tip: Add fresh solder to joint before solder sucking. I do this all the time, works very well.
Solder suckers are just junk, bro. You can do the same thing but better, with other methods. Pro tip from a bigger pro than you. Trust me.
@@THEFlea1991 They work great for older electronics. Been doing this for 22 years. As stated in the video, for micro electronics, wick is king.
It's annoying when people don't know when you're joking. A joke lightens the day.
You can seal the board (waterproofing) with plastic-spray. It’s like a thicker clear spray paint.
Some people just don't understand that there is a difference between repairing for a living and repairing for a hobby. Keep up the great videos, and thanks.
You are awesome technician. I love watching your videos. You are my main reason why, I got into repairing electronics as well. I hope to mee you one day!
Yes in the previous video I got the spammers comment you have won a gift 🤭😃😃😃
It looks like you working 24x7
It's a late night in the USA
I want to say something that not many may think to mention.. but I really hope that you are staying happy and healthy Alex -- eating right, sleeping enough and getting a walk or run every other time as I know sitting at your workstation saving lives day in day out, week in week out is great BUT, you need your YOU-TIME! You have no idea how much you are a lifesaver - not only to the people you actually repair their devices but even to us, thousands of miles away who can watch your content and feel good that there is another good soul out there literally saving the world, a device at a time.. :)
Keep up the good job champ and may you always be healthy.. as you seek happiness in what you do.. which you do so well!
Why did you “think to mention” that?
I learned today: don’t need a sucker and don’t be stupid
Oh it was really neat watching you repair the board!!!!
PCBs that are used in most Whirpools are known to have really hard solder and their holes have rings on the both sides.The best way to desolder with a hand vacuum pump it is also to add lower temperature solder and heat it up well.Usually 60/40 or 60/37 works well for me.
Thank you very much for not blasting me with U.V
I am still recovering from the rays in my eyes! 😅
I have the same machine and have had to do this repair on my machine as well. exact same board. I've also replaced the pressure sensor and still have to replace a few caps on another board for a common SUDS F35 Error. always a great feeling when you can repair our own household items.
