I wish i saw your videos earlier man! Thanks for being a nice guy on youtube :) I was wondering if replacing the chip the correct way (your way) does provide for a durable solution? Or will the bad design of the motherboard eventually make the macbook fail again? Currently im on the fence of either selling my faulty 2011 pro and buying sth new (second hand) or having a replacement of the chip for about 250 euros. Im low on budget... Grts from Berlin
Go back to 22.00, 23.07, 46.28 and 49.20 .Watch how Louis potentially sets himself up by placing the coil of solder in a way that guarantees it will fall at some point. But switching off the machine? That's not right.
55:00 See the death-defying suicide leap by the roll of solder, onto the power-outlet of DOOOOOMMMM, just in time to *F* up the most critical part of the process. :thumbsup:
As always , Louis you are the man. have been in the repair business almost the same time as you, which is around 2008 /2009. been solving problems on the mainboard, but other than that I needed more, and ever since I started going through your videos I have improved my services. thank you bro.
Easy solution for aluminum tape adhesive, naphtha. Aka, Old-school Zippo lighter fluid. Grab a bottle form any local gas station/mini-mart. It will remove just about any petroleum product and doesn't leave a stain or residue. It evaporates quickly, but not too quickly. Good stuff.
I learned to just leave things be a long time ago when I was an apprentice. I was told to chip the concrete away around a clay drainage pipe while the experienced plumber I was working with went to get the connectors to go onto the clay. "Be careful not to crack the pipe" I was told. After doing a perfect job of it and then waiting quite a while for him to get back I decided I'd just take a tiny bit more out, just to make it even more perfect. Crack! Right down the length of the clay pipe.
I admire your patience. I heard someone say recently "perfection is the enemy of good" or something like that. A job like this looks like a prime example; knowing when you've done enough and that it's time to stop is half the battle. Great instructive video as always.
Louis, here's a great tip that might change your life. Get to know your dentist's toolbox. Micro applicators are q-tip or toothbrush like disposable cleaning tools that do not shed by design. It's been great for me in PC repair where contamination was a bad idea and cleaning or application was needed. There are hundreds of shapes lengths and firmness of bristle. You might also like tweezer scissors. Strong enough to cut thick "human mouth", braces wiring and holds while cutting in small delicate spaces. Lots of sizes as well.
For those wondering (and I know there's plenty of them, most have at some point) why not just solder, wick, rework with the solder already on there with electronics. Electronics manufacturing use lead-free solder. Leaded solder is an environmental and personal-health nastiness. So industry has to use it. Lead-free solder work great in manufacturing applications, with the right solder bath setups etc. But, it's utter crap for reflowing, wicking and reworking (manually), once it has solidified. So when doing manual repair/reflow work, you gotta replace it with leaded solder, which is much more manual-work/-reflow friendly. As you can't just wish it all away, you do that by adding generous amounts of leaded solder to the lead-free one, wick away when enough to be decently wickable, add more, "rinse and repeat" if neccessary - progressively boosting the lead/leaded solder content of the solder "mix". Until the mix there is satisfactory, all leaded solder, or the component/pads/whatever are tinned but clean. Whatever your goal is. _Then,_ you can proceed working with it with good flow. This is why a fume extractor is important. Those fumes from the solder, especially the leaded one, is quite bad for you.
damn that was epic when the solder roll fell on the machine breaker, turning off chip suction, throwing the chip into the alignment camera thingy. HAHA. What are the odds!!
Your videos are fantastic Louis, I enjoy watching something with minimal edits and cuts and good lengthy footage really helps IMO - makes it feel much more honest and real, along with including any mishaps, makes me feel like I'm watching a real human and being taught from a real teacher. Keep up the excellent videography!
I really enjoy watching you because I'm learning fabrication SMD, tht myself. Teaching myself. You know what I mean when I say you have found a craft you care about so much that you have become a lifetime student. Your not overly cocky and you really do admit that your in a field that requires constant learning.
my comment might be allot late so here goes, i like the fact that you dont edit out stuff that happens like for instance the soldering wire falling on the switch, but still saves time by not including stuff to your videos like redoing the whole part on the stenciling. Awesome stuff you do man. Keep up the good work.
Developed the patience during days long ago of fooling around with tiny parts. Great video series! Things like "Runing", almost spilled my coffee first time you said it and then showed it on display :D
Its 4am and i have a job interview at 9am. Inevitably i have ended up in a youtube rampage. It has culminated in your video. laughed alot. Really enjoyed your approach. I can relate to the way you work. "goog is great, perfection is shit" hit home. I agree, although i am a perfectionist. Subscribed.
xXFIREWIREXx Thank you! I can't think of a single job interview that went well over the course of my life, which is why I am here working for myself. Good luck.
+Louis Rossmann You never make any decent money working for someone else....unless you are Steve Balmer! >;) Top call on the perfectionist issue! Just spent an afternoon watching your vids when I should be fixing a crashed Quadcopter! lol
You're a True Artisan on cleaning and preparing the board.. thank you for sharing your knowledge and professional tips trick and tools of the industry and experience with us...
Replace that cheap irons cable and it will heat up in 10-20sec. I personal was quite pissed when i found out this fact. They use Coperclad aluminim iin the cable that goes to the iron after you replace it with a good cable it works great and you don't have a shitty cable that folds up and does frustrating things. MOnoprice 24awg usb cords make great replacements:) the "data wires" aka small go to the thermal couple and the 2 "thick" ones go to the heater.
Thank you for posting this video. I just purchased a Zhuo Mao 5860C for my shop and their is very little information available on BGA repairs for people with little experience.
Im a software developer and don't have much experience with hardware but i've always enjoyed the low level stuff where you need to understand the hardware and I love watching your videos! Most people would probably be bored silly watching this process but I found it fascinating! This job would have been much easier on you without fumbling with the camera so I want you to know I appreciate the view! Thank you for recording this and uploading.
every programmer that asks himself, "how am I able to do this, and let this come out of it".. will one day seek the truth and know better. And when he's learning more about hardware level component repair, this programmer becomes a handy modern tech people would actually need
I don't know how I found your channel but I don't think i've been this pumped to see someone involved in repair who follows logic, and top down problem solving. Landed over here from your flowing dead flip chip video and my god was watching the original Linus one frustrating because of just how much it wasn't backed by anything credible. Thanks for doing your work to spread information about mis-information ( wasn't sure how to phrase that sentence ha)
Am I the only one who noticed he released a video on not letting people spend holidays alone, and this was released December 23rd late at night? Way to make it productive man!
Today is July 15 in 2019 - I just noticed you published this on my birthday so you were working on Christmas Eve or around there. I have seen these contraptions and I am amazed you have one as well, these - to me - are magical like robots and I wish I lived in NY. But alas... Love your vids Louis.
No matter how much you think you know, one can always learn......great tips. I’m sure seasoned techs probably watch as intently as someone like me who knows squat about working on computers.
It's amazing how slow these things are with those mechanical drives, I swapped out a 250gb Toshiba from a 2009 13" Macbook pro to an SSD and it feels like a whole new laptop.
as i expected i really enjoy and learning a tons of knowledge from you louis rossman thank you so much....just to be honest i love watching your videos
Infra-red rework stations like Ersa IR450, IR500 or most recent IR650 have advantage of perfectly aiming IR beamer just on the chip using apertures while not blowing other stuff around off (like small 0402 capacitors), which is what hot-air stations usualy do :). It also has semi-automated pull-of with suction and when the solder melts, it pulls the chip away quickly.. And btw those hoses sucking messy fumes at around 25min are heavily affecting the temperature profile.. which should be measured with some thermocouples. One placed on the bottom, one next to the chip and one directly on the chip.
Concerning the MEK cleaning on the pads: Ive got good experience using medical non-sterile bandages. Very cheap and woven in a way that no fiber leaves the material when abused as a swipe. Just cut some cm of material, fold the cut ends inside and use as a cleaning tip either on tweezers or a needle holder if available. Everytime repeatable, clean results for me.
i use gravity to get most solder of the circuit board after removing the component, afterwards i use a hot weller vacuum cleaner, i also use glasses 1.5 or 2 it enlarge a bit, i can also recommend the camera in a phone. That with the camera is ok, I would probably try a heat camera too but then you probably can't see when the soldering goes together
There was a machine I used (can't remember the name of it) when I worked at Texas Instruments to assemble the board to the screen on Ti-81 calculators. It had the microscopic lens etc. I was straight out of High School. Great video!
I own a Honton R-490 v1 - had for like 5-6 years works like new ;) but I really like your system with the overhead camera & nicer software. I know its bells & whistles but looks nicer but both work & get the job done. great vid, cheers
Harbor Freight has 3 (white), 5 (blue), 7 (green), 9 (black) mil nitrile gloves from $7-$12 one or two thicknesses are on sale (with coupon) every other month it seems. 3 and 5 mil have 100 pairs per box, 7 and 9 mil have 50 pairs per box. Available in 3 sizes or maybe 4 sizes.
Oh my god.... that reel of solder and how you turn back to look at the camera had me laughing my socks off. Unless it was recorded NOBODY WOULD BELIEVE IT. Seriously, some things that happen are beyond insane. That machine must be afflicted with the “May you live in interesting times” curse. Louis, your videos have me laughing more than at some professional comedians.
New subscriber here. I've been learning a lot. Thanks so much and looking forward to more. - - - You mentioned that the adhesive on the Nashua tape is almost impossible to get off if you get it on your hands. Just FYI, I've never met an adhesive that won't come off almost any surface in 2 seconds using Zippo lighter fluid. Of course it's totally unsafe so be smart about it, but if you need to remove stubborn adhesive from a material that can handle it (e.g. glass), nothing works better and of course you can get it at just about any store that sells cigarettes.
The silver Nashua tape is actually just duct tape. Used in air conditioning repair to seal joints in ductwork and other types of air gaps. The tape is also pressure applied. Meaning you use a squeegee, or a credit card, or something that you can apply pressure to adhere it. i know this from the days I worked as an HVAC repair man. Universal HVAC certified except I now refuse to climb in an attic to mess with an evaporator, since I live in Florida. I remember looking down at my temp sensor and seeing 160° F readings on a daily basis, in the summer. Dont become an HVAC tech kids. Worst job ever. Even I could only stand a couple of years in my younger days. BTW I enjoy your vids Louis. I learn something in every vid brother. Outstanding.
So you do have a BGA rework station. I contacted your shop last week hoping you could replace an LGA 1151 socket on my iMac logic board. Your people told me you don't do that. It's a shame. I admire your work and hoped to give you my business. I had to bring my computer to LaptopMD. I hope they're good and can help me.
I hope I did not jinx the current situation with Apple. But probably Tim is more liberal then his lawyers and the current situation leads the support of Apple for the right to repair bill and a more open policy off Apple towards documentation and a lenient and clear policy towards design flaws. So I still hope Tim sees this :)
I soak boards in isopropyl alcohol to dry them out and clean off crap. It's great for removing salt water off of an iPhone PCB.. like mine, when it took a swim in the Pacific Ocean.
Hi Louis, I'm a computer enthusiast and a IT worker and I've been following your channel for a while. Love your work and Im pretty interested in it. I have a non working laptop (powers on, fan spins, but no image in the screen or via hdmi) and I want to repair it in order to learn and possibly include this service for my customers in the future here in Spain. The thing is the videos are quite long and you don't spend much time explaining techniques, so, if you admit suggestions, I think a series of short tutorials explaining techniques as microsoldering, desoldering, diagnosing problems, following schematics, sources or software for them and such could be a great value in your channel for those who want to enter in this world.
55:00 and I had actually been wondering for a while if you had a UPS for that machine just in case of power failure. Turns out a UPS wouldn't have helped with bad power switch placement :-D
I wish you the fucking best in this life ... Dont know how to thank you enough ! Since today and forever you will be for me his excellency Don Louis Rossmann :) Although Im absolutly not related to IT tech or having a repair shop, I really like to understanding how to fix them etc... so some "specialist" will not screw me over and over like before. Youre the Man and a huge source of inspiration, thanks you.

Love your work! I learn a lot watching your stuff. Thanks for sharing your hard-won experience and knowledge!
Are those gpus still available new?
When you're so bored you end up Watching a Louis Rossmann repair video from 5 Years ago.
Hahahah lol long even hour. :-[]
It's both good, as in seeing how he's changed and his methods, and just nice noise to have in the background.
Haha, same here! I like Louis v.2014 though.
Yes lol gawd
5 years? Greetings from Monday morning at 6 am in 2020
6 years now, and still enjoying these videos on safe distance...
@Blank Gaming fucking apple, full of shit inside and out!
I'm having Anxiety just watching the whole process. And if I perform the task than I will probally piss my pants on the spot
@Gaming York yes they can, some do
Best part at @55:00 that moments that really tests your patience...
+Morjesta! Its the funniest part :D
I started scrolling through the comments to see if anyone said anything! Not disappointed.
Strong is the Murphy's law in that one.
Go back to 22.00, 23.07, 46.28 and 49.20 .Watch how Louis potentially sets himself up by placing the coil of solder in a way that guarantees it will fall at some point. But switching off the machine? That's not right.
i laughed so hard ahahahah murphy is always right.

I don't even understand how is he even able to speak so calmly after that happened.
Lol i fuck that fucking machine lol arrgghhh
Mann i would be so pissed off
That was great.
As always , Louis you are the man. have been in the repair business almost the same time as you, which is around 2008 /2009. been solving problems on the mainboard, but other than that I needed more, and ever since I started going through your videos I have improved my services.
thank you bro.
Easy solution for aluminum tape adhesive, naphtha. Aka, Old-school Zippo lighter fluid. Grab a bottle form any local gas station/mini-mart. It will remove just about any petroleum product and doesn't leave a stain or residue. It evaporates quickly, but not too quickly. Good stuff.
I learned to just leave things be a long time ago when I was an apprentice. I was told to chip the concrete away around a clay drainage pipe while the experienced plumber I was working with went to get the connectors to go onto the clay. "Be careful not to crack the pipe" I was told. After doing a perfect job of it and then waiting quite a while for him to get back I decided I'd just take a tiny bit more out, just to make it even more perfect. Crack! Right down the length of the clay pipe.
I been addicted to your videos. I'm just watching one after another.
Same here. Also learning a lot :)
same ;)
I admire your patience. I heard someone say recently "perfection is the enemy of good" or something like that. A job like this looks like a prime example; knowing when you've done enough and that it's time to stop is half the battle. Great instructive video as always.
Louis, here's a great tip that might change your life. Get to know your dentist's toolbox. Micro applicators are q-tip or toothbrush like disposable cleaning tools that do not shed by design. It's been great for me in PC repair where contamination was a bad idea and cleaning or application was needed. There are hundreds of shapes lengths and firmness of bristle.
You might also like tweezer scissors. Strong enough to cut thick "human mouth", braces wiring and holds while cutting in small delicate spaces. Lots of sizes as well.
I'll be talking to my dentist about giving me some of these to try. Thanks for the tip!
i admire how calm u can be at certain situations, wish i was like that

"The only way to learn what you're doing is to screw things up." -Louis Rossmann
If that's true then I must be an expert on everything.
It's amazing how slow these things are with those mechanical drives, I swapped out a 250gb Toshiba from a 2009 13" Macbook pro to an SSD and it feels like a whole new laptop.
He was only 26 in this video. It's impressive, I think, when young people own businesses, buy expensive equipment, rent a store, and so on. It's cool!
The Best! Louis Rossmann
"I'm in past , you are in future... " I liked that line
That solder falling on the switch is so hilarious! 😂😂😂
I LOVE the view of all the BALLS! Excellent Job, Man!
I love how he hit start and then says ruining instead of running
as i expected i really enjoy and learning a tons of knowledge from you louis rossman thank you so much....just to be honest i love watching your videos
The solder falling was such a great moment, glad I was paying attention right as it happened, hilarious. **deep breaths**

the biggest challenge amongst all of this is finding chips that aren't bullshit

i use gravity to get most solder of the circuit board after removing the component, afterwards i use a hot weller vacuum cleaner, i also use glasses 1.5 or 2 it enlarge a bit, i can also recommend the camera in a phone. That with the camera is ok, I would probably try a heat camera too but then you probably can't see when the soldering goes together
There was a machine I used (can't remember the name of it) when I worked at Texas Instruments to assemble the board to the screen on Ti-81 calculators. It had the microscopic lens etc. I was straight out of High School. Great video!
Random question but in America the main type of calculator seems to be this Texas Instruments type, no one uses Casio then?
The metal tape is used to patch air leaks in duct work on HVAC and is heat activated and fire proof. That’s why so goopy!
*pulls it out the oven" "... if it gets to hot it will be destroyed "
I own a Honton R-490 v1 - had for like 5-6 years works like new ;) but I really like your system with the overhead camera & nicer software. I know its bells & whistles but looks nicer but both work & get the job done. great vid, cheers
Most professionals: It appears that there has been some improper work performed on this device.
Louis: This machine has been fucked with by an idiot.
Harbor Freight has 3 (white), 5 (blue), 7 (green), 9 (black) mil nitrile gloves from $7-$12 one or two thicknesses are on sale (with coupon) every other month it seems. 3 and 5 mil have 100 pairs per box, 7 and 9 mil have 50 pairs per box. Available in 3 sizes or maybe 4 sizes.
Oh my god.... that reel of solder and how you turn back to look at the camera had me laughing my socks off. Unless it was recorded NOBODY WOULD BELIEVE IT. Seriously, some things that happen are beyond insane. That machine must be afflicted with the “May you live in interesting times” curse. Louis, your videos have me laughing more than at some professional comedians.
I am enjoying your video's so much, you are one heck of a technician, and on top of that very entertaining too!
New subscriber here. I've been learning a lot. Thanks so much and looking forward to more. - - - You mentioned that the adhesive on the Nashua tape is almost impossible to get off if you get it on your hands. Just FYI, I've never met an adhesive that won't come off almost any surface in 2 seconds using Zippo lighter fluid. Of course it's totally unsafe so be smart about it, but if you need to remove stubborn adhesive from a material that can handle it (e.g. glass), nothing works better and of course you can get it at just about any store that sells cigarettes.
Louis every time you put a screw in while it's on you scare the hell out of me and I get PTSD from my first personal iPhone repair
I don't care what anyone says.... These are the best sleeve shots in the game!
Man i love your videos straight to the point very explanatory love to work for you
The silver Nashua tape is actually just duct tape. Used in air conditioning repair to seal joints in ductwork and other types of air gaps. The tape is also pressure applied. Meaning you use a squeegee, or a credit card, or something that you can apply pressure to adhere it. i know this from the days I worked as an HVAC repair man. Universal HVAC certified except I now refuse to climb in an attic to mess with an evaporator, since I live in Florida. I remember looking down at my temp sensor and seeing 160° F readings on a daily basis, in the summer. Dont become an HVAC tech kids. Worst job ever. Even I could only stand a couple of years in my younger days. BTW I enjoy your vids Louis. I learn something in every vid brother. Outstanding.
So you do have a BGA rework station. I contacted your shop last week hoping you could replace an LGA 1151 socket on my iMac logic board. Your people told me you don't do that. It's a shame. I admire your work and hoped to give you my business. I had to bring my computer to LaptopMD. I hope they're good and can help me.
I could be wrong, but isn't it extremely hard, if not impossible to repair an lga socket?
If I keep watching I’ll know,good show....
A large solder ball to pick up small solder balls is such a good and obvious idea
you are an honorable man looking for honorable people. Hope that Tim sees this.
Tim?
Tim Cook, CEO for Apple
Lorenzo van het Hul doh
I hope I did not jinx the current situation with Apple. But probably Tim is more liberal then his lawyers and the current situation leads the support of Apple for the right to repair bill and a more open policy off Apple towards documentation and a lenient and clear policy towards design flaws. So I still hope Tim sees this :)
Tim cook is the old guy for Apple
hey man if it's worth anything, glad you recorded this with all the "imperfections". truly a masterpiece.. also really funny :))
Ah HahA I almost cried when Murphy pushed that roll of solder on the switch.
+Think Lab :( So did I :(
It was not Murphy it was I from the future; its 2020
I soak boards in isopropyl alcohol to dry them out and clean off crap. It's great for removing salt water off of an iPhone PCB.. like mine, when it took a swim in the Pacific Ocean.
Not sure if someone commented this yet but the silver tape is for ductwork. Commonly called foil tape
loved your perfectionism rant - thanks again for all your vids!!
I really enjoy watching your videos u really make shit look easy
Hi Louis, I'm a computer enthusiast and a IT worker and I've been following your channel for a while. Love your work and Im pretty interested in it. I have a non working laptop (powers on, fan spins, but no image in the screen or via hdmi) and I want to repair it in order to learn and possibly include this service for my customers in the future here in Spain. The thing is the videos are quite long and you don't spend much time explaining techniques, so, if you admit suggestions, I think a series of short tutorials explaining techniques as microsoldering, desoldering, diagnosing problems, following schematics, sources or software for them and such could be a great value in your channel for those who want to enter in this world.
Some things are gained only through trail-(trail-trail-trail-)-and-error.... others, are called education :) especially diagnosing problems.
42:44 I think the more common saying about this is "Perfect is the enemy of good."
Captain Tape is the superhero we need, not the one we deserve.
Love your work Louis
1:29:35 Yesterday's tape drives are today's hard drives. Ssd is prime upgrate for old computer.
I die of laughter every time he says balls on this video
TheHolly Boi You should consult a doctor.
That video helps me a lot, thank you!
Your tools are very good and in it
Try do that with an Ira like ACHI 6000. Nice work Mr. Rossmann, as allways.
55:00 and I had actually been wondering for a while if you had a UPS for that machine just in case of power failure. Turns out a UPS wouldn't have helped with bad power switch placement :-D
31:20 - SUSPENSE!!!!
I was wondering what the hell was going on 😂
I wish you the fucking best in this life ... Dont know how to thank you enough !
Since today and forever you will be for me his excellency Don Louis Rossmann :)
Although Im absolutly not related to IT tech or having a repair shop, I really like to understanding how to fix them etc... so some "specialist" will not screw me over and over like before.
Youre the Man and a huge source of inspiration, thanks you.
Nice job Louis, thank you for sharing with us!!!
