Love your videos man. It's like a cross between Zen computer repair and motherboard-porn.

[@BeeTee69]

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

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.

[@Morjesta]

Best part at @55:00 that moments that really tests your patience...

[@CodeAsm]

+Morjesta! Its the funniest part :D

[@hurtadoa1]

I started scrolling through the comments to see if anyone said anything! Not disappointed.

[@SeersantLoom]

Strong is the Murphy's law in that one.

[@DavoidJohnson]

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.

[@jonathanbignall1198]

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.

[@karlosp02]

i admire how calm u can be at certain situations, wish i was like that

[@laernulienlaernulienlaernu8953]

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.

[@Essentialsend]

I watch your vids not primarily for the computer repair lessons, but for listening intelligent comments. thx my friend

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.

[@nightfox6738]

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.

[@toketwo]

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

[@ernstrudolfhayward4078]

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.

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!

[@michaelsanders5815]

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.

[@nestorwheelock1314]

I'll be talking to my dentist about giving me some of these to try. Thanks for the tip!

[@xXFIREWIREXx]

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.

[@rossmanngroup]

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.

[@derekzhu7349]

I’m never going to to anything like this in my lifetime but I really enjoy seeing how things work. Love your videos!

[@pr0xZen]

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.

[@NailedDownClick]

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)

[@madspoulsen4243]

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!!

[@Ed-ty1kr]

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.

[@KoosIJtsma]

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 :)

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.

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.

[@vincentvalentine5900]

That solder falling on the switch is so hilarious! 😂😂😂

[@xmeda]

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.

[@rossmanngroup]

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

[@OG_Zlog]

I don't care what anyone says.... These are the best sleeve shots in the game!

[@gordhenschel1419]

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.

[@adaboy4z]

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!

[@wsketchy]

Random question but in America the main type of calculator seems to be this Texas Instruments type, no one uses Casio then?

[@KingOfKYA]

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.

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.

[@jjones503]

As the great manson once asked. "Tell me how, does it feel?" Manson obliviously got his inspiration from louis.

[@jacobhn2]

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

[@SLetsP]

Try do that with an Ira like ACHI 6000. Nice work Mr. Rossmann, as allways.
