Mrs. Chokesondick: "Present them!"

There's something really hypnotizing about the way light catches on melting flux. 5:20

I do SMT rework during semester breaks at an EMS factory and I really like you videos. In fact, I'm playing with the idea of offering repair/modding services myself. Not for Apple products, but in general. Game consoles maybe. I'm fairly good with tiny ass SMD soldering and hot air rework. But it doesn't matter how many of your videos I watch, I'm always grossed out by the obscene ammount of flux you use on those boards. I love it! :D I tried it too, it works great. It's just disgusting and a mess to clean up when you're working on brand new boards fresh from the reflow oven and you can't just toss them into an ultrasonic.

4:40 its not the value of the jumper wire louis, its the efficiency and knowledge u utilize on fault finding. we get paid based upon that man. u r my hero, from far away in INDIA I learn macbook motherboard repairing from u and earned my living, u r my guru.

I bought some Amtech flux from Louis a couple of weeks ago - "he's got the good shit...". After dealing with Kingbo and the Chinese knockoffs, getting my hands on the real deal has made my work so much easier. No doubt that this solder paste will yield the same results.

22:45 "And my stencil just got sucked up in my air filter. Great" It's these little things that honestly really bugs me.

The mother of my friend was back in the day a home worker for an electronics manufacturer. Her job was to assemble little coils onto a core and attach the wires to the throuh hole leads. The company gave her a little pot with integrated heater, where she melted the solder (Pb) and diped those prepared coils in order to solder them. She was very fond of her work, because she got payed per pice. Now the woman has throat cancer, have got her larynx removed. And out there someware lives happily her former boss who is responsible for all this.

Hi, Louis. the needles for the solder paste: dentists throw them away all the time as they empty the ceramic syringes for tooth repair. (source: it's what I use..)

I'd say you are really freaking good on what you did. Hats Off..And those equipment especially that scope is just one of dream, than just using a magnifying glass the ruined my entire eye as year passes by. Just before I have a 20/20 vision on what I do. But now, I can't do that stuff anymore. I can't see a damn thing smaller than .5mm of a ball..

+Louis Rossmann For your needles go to All Spec's website and search for "loctite dispensing needles" Just look for one that is the same color as you've been using... the color correlates to the wire gauge of the needle. CML Supply on Amazon also has a dispensing needle assortment available.

Syringe tip tipp :-) Just go to your local ER with some donuts, cookies and quality juice at quiet times. Syringe and stuff in all sizes. If its dull and not sharp, probably for infusion things/catheter, which get/stay inserted after the hole is punched in your skin... even if its not your orignial one you might find something that fits.

You want stainless steel Leur-Lock dispensing tips.. Not entirely sure which gauge you want, but 18 gauge has some difficulty sucking up VG (Vegetable Glycerin, for my DIY vaping liquids hobby), but can dispense it decently with a bit of force (similar with 20G) - which may be what you want for solder paste. I got all mine via Ebay in packs of 12 for pretty cheap. For reference.... I think 8 gauge is the widest available -- and also practically all, if not all, syringes are Leur-Lock or Leur-Slip, with both being the same size and all, but the 'Lock' version has the screw-type connection points to, well, lock it in. :) To cover your initial bases, I'd probably try a pack each of 16, 18, and 20 gauge - they're cheap enough (~$6-8 each).

You'd be surprised at how easy it is to deal with US manufacturers in this way! Especially if you're willing to provide/deliver the cartridges. SMT used to provide their AMTECH 4300 series pastes to Howard Electronics in 10CC syringes many years ago, it's likely that they still have the facilities to fill these types of cartridges but they don't normally offer them as a product for purchase Another case; I was able to obtain consent from a US plating manufacturer to resell their plating chemicals in small vials for hobbyist use, even with my own label attached to the vials; I barely buy a few hundred dollars worth of gear from them a year!

PodeCoet In the United States, you have a legal rights to resell most things under your own imprint, without consideration of the company you buy it from. Chemicals are not particularly protected, unless you need licenses or permits to handle or transfer them. It just isn't economical to deal with US manufacturers when the chemicals are dug out of the ground in China or India, processed there, and shipped to my business cheaper per kg in small quantities than I would pay a US company for the same in bulk, since they are sourcing it from the same people.

what did you use to clean the stencil of extra solder paste, alcohol kleen wipe or dry?

I have a question, where do you buy your gpu and so on and so forth stencils? anywhere places sells all types for everything out there? Lets say a Gtx 780 pcb for the GPU die itself? or maybe a specific raid card?

amazing !!!

Do you keep the solder paste in the fridge when you’re not using it or do you just leave it on the side?? Does refrigerating it make it last longer???thanks jay

26:15 You can mark the board with old chip on it

Hi! What kind of clean paper did you use for the clean? Thx

Good job bro!..

Louis, sometimes i wonder how much you would save a year if you didn't use so much damn flux lol. good video, and a very clean reball

more flux = more successful jobs = more money and less bad reviews from clients

Another great video Louis, I start to think I should try a board fix myself. Question, wich is why I want to try myself: If I have a special board, no laptop motherboard but a special gameconsole board. What would be a reason not to help a customer replace a bga chip that he also provides, offers whatever money you need for it and atleast align it the same way but if the board is bad or chip, doesnt matter. I have some clues but why would most repair shops dont take this risk? "simple" "southbridge" replacement, customer even has the chip from a donor. and it doesnt matter if the replacement doesnt work. (I hope it will, but ill take the risk)

wow i didn't know the solder paste turns into ball solders. Brain wasn't working haha. Thats cool. I want to do this just so i can feel the satisfaction on working on my own shit and fix my own stuff, not making money. I'll still buy what you have just to make it work perfectly. Also noticed the balls don't stay stuck to non adhering pads. So good :D Learned couple things xDDDDD Was so used to how everyone else reworks bga parts by throwing balls into stencils 23:25 what is the chip die holder called? Also do you know if the soldering balls are better or the paste overall better in longevity because its a paste and so on other than the benefits of it being easy to apply?

Whats the clamp you're using to hold the chip for reballing?

The needle looks a lot like the ones that come with ink refill kits metal pink plastic connector to go to syringe tip. Also medical supplies stores used for irrigation of wounds if you were still interested

you might know this by now but maybe some else doesnt but solder paste tubes and flux tube needle connections are called "luer lock"

Louis, why don't you use your BGA rework system to align and place the BGA chip ?

Hey louis, that claning cloth is static safe?

Good video can you please tell me how much degree is Hot airgun station and soldering iron.

Sorry if its idiot question's. I see often syringe flux but without nothing to push the flux in the needle. So what you use to push the flux in the syringe ? Also what is the temperature of your working station ? And what temperature of your iron solder with wick ? Since stencil are expensive (we can't buy all of them) does exist like general stencil we can buy ? Do you think you can clean your stencil in ultrasonic cleaner ? Really appreciate you share your knowledge with us. Share is so rare today and even rich want make sharing criminal. Thanks for all your teaching.

What temperature was the air set at to take the SMD off at 04:21?

Ur videos are clear as crystal..I am an beginner could post a video about how to know the path in a pcb or could you send a link for a video that it tells you about path of a pcb

where do you generally buy your donor boards?

Can you make a video on how to put the syringes together? I can't figure it out.

hi louis where did you get the stencil

Referring to the 17 minute mark. Does that syringe use the luer lock connection for the needles? You can get blunt needles of various gauges off Amazon and Ebay, and there's a good chance you can ask a pharmacy or a hardware store with livestock supplies for needles.

You can buy this needles in pharmacy store!

Gotta wonder if there is a way to mark the board before taking off the chip. Or maybe a cold stencil. But it obviously positions itself due to capillary action, equalizing. Would you even think about trying this lead free?

hi Louis, what you're doing with the Mac-Stuff is just amazing (or I'm simply not able to find the right word for that..).A very - for you - simple question: the SD-Card reader on my MacBook Pro (2012) doesn't work any more (I simply put the card into the slot=>no reaction). Is the card-reader easy to build out and in, or is it a solid part of the mother board, means, it's not that easy to replace it?Thanks for your answer.

Hi Louis, thanks for your answer. I got the Mac from my brother-in-law (a very heavy smoker!) and the card reader was simply as dirty as hell. So I took an old SD-Card, a very thin but strong piece of my wife's old shirt, wrapped around the card, took some alcohol (as you always suggest) and push the card into the reader (nothing to lose should I break the reader...). I repeated the action 4 times and: success!! So as you said: ...something but the card reader, you're right. Thanks for your help!

Is using solderwick and dragging it instead of dabbing it better? A lot of you tubers only suggest dabbing, what’s your take?

I've seen some of your videos, and suscribed too, I understand everything but I don't know WHEN the bga is soldered!! How or when do I know that's soldered??? Do you have a video on that? Thank you and learn a lot on this channel. Regards from Buenos Aires city, Argentina

Louis where did you get the syringe for the Amtech paste? I have that same solder paste but cant figure out how to get it out of the tube in came in. I guess it takes a syringe to load it in . Beats me. Show us how to dispense that paste please.

Bonjour! :-) what is your air filter please?

what is the name or model number of wick wire you use?

Probably luer lock standard blunt needles. Of course you can buy them on ebay now.

Hi Louis, when will you have these back in stock?

hello louis can you tell me whats the temperature you use soldering iron plz

Maybe you could somehow mark down (white marker?) the position of the original chip?

Louis, i know this is old video but about the tip of the needle 17:15 its seems like a LUER-LOCK tip. idk if you resolved that but just in case.

Heh... that's the second time I've seen something get sucked up into your airfilter. At the risk of belabouring the obvious... have you thought about putting some screen mesh, like window screen material, over the intake nozzle of your filter system? Anyhow, great video as usual. I couldn't tell if the audio was still not synching properly on this one. ETA: Yep, audio is slightly out of synch. This is obvious at the end of the video.

Hello Louis! Thanks for your videos. Please, provide legend for Portuguese (Brazil). This will help us Brazilians. Thanks.

It strikes me that these stencils you could get manufactured from a local machine shop. Chances are they'd be able to make a little jig for you to fix the chip and the stencil in the correct position, too. Should be child's play for them. Just give them a pattern or a 1:1 photo, and you should be set.

So a few Saturdays while in the shop and not recording my own videos I put you on the 40 inch monitor and been watching ever since. Thought it was time to subscribe. Our work is similar. You work on stuff that others have messed up and have unobtainable parts and no support, I work on vintage communication radio and test equipment, some that has been butchered and no availability of parts. So I relate to a lot of what you do. Keep up the good repairs and commentaries, I enjoy them.

I've watched all these videos, but in the end, I couldn't find the answer to a question that might be stupidly simple. What is an SMC? What does it stand for?

Not 100% sure but your syringe tube might be from an inkjet cartridge refill bottle ! Here in the UK we can cheapskate it and buy little bottles of ink to refill the colour cartridges on our printer and save a little money. The bottles come with these long narrow tubes. for pushing down into the cartridge. You then squeeze the bottle to force the new ink into the old cartridge. It works for one or two refills before the insides fuck up completely and you need a new cartridge.

When i dont have those kind on needles, i go to the drug store( sometimes they are not willing to sell me because they think that im drug user. ) and buy the biggest ones they have. When i come home i cut off that sharp part and it works (for me).

18:10 This might be totally not relevant anymore 2 years later but a lot of these thingies are easily sourced via aliexpress. Just smash in some keywords that might match what you are searching for. Standards in china work a little different, usually its just the right mixture of keywords that define an item. No DIN standards or stuff like that. Needles for syringes f.e. are usually the same and you just search for dispensing needle and get a f* ton of different needles that will likely all fit any of your syringes nicely. Same goes with other parts.
