Great to see something fixed, even better to see something fixed that wasn't designed to be fixed.
@@bennaambo2716 Does it need to be that form factor?. Would the customer prefer a slightly larger form factor with Dimms?
@@bennaambo2716 I guess there is something lost in translation as I don't know what you're talking about Sir.
By the way, do you know a Mr. Ben Dover?
Ok, bye!
One thing to note again, and I'm glad you did, is when you do BGA reflows you don' t need to use much flux. It will appear, especially when the board is hot, that it has dried up. This isn't the case - it has merely been sucked under the chip. Unlike QFN packages, BGA chips sit slightly elevated, so things can easily get under them...including corrosion. For newcomers, notice how on BGA chips Alex never presses down? That's how BGA chips work - they're slightly elevated by the density of the solder balls.
And before you reflow, do the press test. The air models are very flexible due to their thinness, and as such, the BGA chips sometime separate from the board itself. Powering the machine on while pressing down on the ram chips can help you determine which one is bad (if you're not confident in your reflow ability). Same goes for most BGA chips - look for corrosion and, if none, try the push test. Then proceed as needed.
Nice work, Alex.
Great work as always! Very efficient!
I had the pleasure of being able to speak with the master in person. Spent a good bit chatting with me about the craft. Appreciate it considering what your backlog looks like. 😳 Thanks for the thermal paste!!! Got me some of that secret sauce! Lol
All the best!
Saving the planet, one device at a time! Nice one. Not many repair shops would have even attempted to fix that issue.
You are the best!!! I want to thank him because recently I went to the shop, no matter if you buy a single thing or many he is always willing to help humble and educated!!!
You always make me smile at your enthusiasm, thank you.
It’s a job that I do some times, but I do all ram chip of a time and so the others won’t have problems. Great vídeo Alex
If it's not broken don't fix it. You can end up creating a problem that didn't exist.
Alex analytical mindset is unmatchable. So much informations and so much helpful.
I have three MacBook Pro a1398 logic boards sitting in a drawer with bad ram issues customer decided not to send out to fix but rather replace with upgraded board. as soon as I order my equipment this summer, ill be fixing those and putting them in topcases to sell. thank you Alex!
Lol I love how you were just like, “screw it, let’s just reflow em all now.”
You should make a t-shirt knowledge is free money. I'm 66 years old and I can't believe how cool you are good job buddy
Nice...very nice. Its better to touch up all of the chips instead of just one or two, assembling and testing and than touch up the next two chips...and so on. It would be much faster if you do all of them at once. Thank your for the video, greets
Never thought about doing that, learn something everyday. Would a thermal cam pick it up? I would assume you could do a ram upgrade as well or would board need to be re programmed?
A hand shake isn’t to show how strong you are its meant to show you mean no harm by showing you have no weapon in your hand
he means how its customary to shake with a very FIRM handshake, not about the handshake itself, but how your considered a weak person if you don't shake FIRMLY. I hurt someone too once so I only go for a medium firmness now. old customs are being broken all the time anyways.
Just did a reflow. Works! 👍
A client brought the same issues to me today I am going to try this method tomorrow 😅 thank you.
Happy to see device is fixed
Is there any delay in the picture with such a microscope? And is it comfortable to solder, when you do not look directly on a board? Thanx for your video.
Thanx Alex! Whats the name of that liquid you put before heating?
Wow that's knowledge... just knowing where to look and what to do. Also the right tools for the job are needed but very nice repair Alex.
Why did you listen to this elder about the shaking hands you mentioned? Great video. I should have watched this a long time ago.
Something very complicated made look very easy. All of the fun tools you could need. Haha
So would you say just to buy another laptop that supports the SSD ram stick ?
Wow. Nice Job. I wish I could be there to learn physically.
I am mesmerized watching these fixes.
I would need a push to have an attempt with a Surface Pro (6); does it suppose to beep same way if memory is a problem? It stucks on boot with a frozen screen, even from USB, hence no recovery option. Just wonder if bad SSD can also do that?
Thanks once again for sharing knowledge!
Regards from Portugal
I notice you press down on certain chips when reflowing, but this one you did not press down. Can you explain that please? Thank you and I love the videos
I enjoy all your videos but I have to disagree on the 500 degrees hot air I'm afraid (I'm assuming Celsious as you say "at maximum"). I appreciate that for a quick reflow "faster is better" but 500 degrees cannot be right. Still enjoying your videos though :)
The Temperature will drop significantly depending on the distance between the pcb and the soldering device. Its not like the PCB is actually 500deg
The last one i have made it in this way, it was not working. Lucky you 👍👍
الله يبارك في علمك وذكائك
We said "ta da " at the same time. Lol ..... I really enjoy your videos.
Good work done, continue to educate the world with Technology
Hi, first of all, I admire your work. It is sensational. I wonder which flux you use for reflowing BGA chips?

@@rahulmechatronics Thanks
Great Video as always , thank you
A master at work. The way you do your job is an art. As for the Apple... I will never buy one. The lack of replaceable RAM and other components... makes it an insult to what a laptop means.
apple isn't the only one doing it, and you are missing out on the benefit of the ram being soldered. latency is a thing of the past. Besides, MacBook Air boards are 150 dollars. I steer customers toward upgrading their board when they need a new one, and in 8 years I have three machines with ram issues. Onboard ram is a non issue. Onboard storage, that's an issue! ill get behind you on that fight MirceaD28
how hot do the memory chips get themselves? Ever tried this under the thermal cam?
And btw my fishing buddy who is turning 73 this year, he sometimes squeezes my hand when we shake just for giggles (I'm 36 and been body building for like 20 years)... It is incredible, feels like his hand is a vice or something, I can bet he could brake my hand just by squeezing it in a heart beat. Yeah, and he worked with his hands whole his life, and does wood carving (only with a knife) in his spare time...
I learnt something new today. Thank you!
you are so skillful
Mr. Alex, I hope you are using Acacia honey in your tea instead of sugar.
Much more healthy Sir.
I use it in mine.
When I worked in Baghdad I would go to the local vendors and buy it by the jar.
I thought you'd say after doing 8 , "heck let me just do all 16". Lol
Great job as always🙌🙌
Fix but is the system reading all the ram? Example 8gb but it boots up with 4gb?
But giving a firm handshake will show that we are confident.
Alex the "nuckle cruncher" 😂🤣
I have pretty close similar problem with my macbook air mid 2012 A1465 now i have to fix this issue myself
Love from Bangladesh ❤️❤️
What temp and what fan speed you set for this process
How long do you think a ram reflow will last? what about a GPU reflow? Would you call this a data recovery or repair?
عمل جيد و لكن اليكس اظن و هذا اقتراح لك انه ان قمت بشرح موجز و صغير لعمل القطع او البورد في بداية قيامك بالعمل فسيتكون فيديوهاتك اسطورية و غنية أكثر بالمعلومات لانك حالياً فقط تستعرض مهارتك و هي رائعة و لكن اظن ان تمرير بعض المعلومات التقنية سيكون افضل لعملك .. كل الشكر لك
Amazing job as always.
nice job! better than factory 😅
amazing job an
thank god that u exists
Reball lebih baik daripada reflow...kalau hanya reflow kemungkinan kasus sama akan terjadi
Thanks Brother its work
good job mate.
nice
Nicely done
Hi, i have macbook air 2014 it had same probblem 3 beeps, after reflow ram chips nothing changed so i reflow PCH, after that i have 1 beep (probably macbook cant find ram) can You give me some advice where to look now? Change ram chips or something else. Thank You.
You're the best!
Good job as always
What cup preheater is that? :D
Nice work.
Great job
I have twice tried to reflow ram on my MacBook's, second time it worked, first time it didnt as i accidentally gave too big of a nudge to ram chip and it pretty much messed all solder joints under the chip and it needed reballing and bga soldering in professional shop.
You had a go, that's what matters 😀
Interestig fix 😁👍
Big Boss is magic, you too!
amazing job
Hello. what she heat ic?
I not found. Detail repair
What temperature did you use for the reflow?
Practice. That's the secret sauce in these kinds of repairs. Your hot air is calibrated differently, so there is no right answer. I've done these before and it's scary at first. You can only practice on your own stuff.
A weak handshake is offensive, but I meter my handshakes based on the strength of the other person.
Excellent work but of course with windows 11, anything before 2017 will be in the trash because of MS's insane CPU security requirements and you cant even choose.
@@mikeycrackson Actually you can install windows on a Mac when you know how. My point was that think of the massive MS users and all the good LT's and DT's thrown away as Win 10 becomes unstable a few years after its final dates which have already been announced. MS has taken requirements way too far and the world will be hip deep in leggo bricks, golf balls, and perfectly good fast computers in landfill...
u can install win11 on devices before 2017 just use a patch to bypass security restrictions
@@husseinal-awawdeh7268 Excellent, i didnt know anyone had done that or that MC might actually hear all the complaints and tweak win 11 to allow older CPU's , So what or where do i get this patch? Thanks
@@husseinal-awawdeh7268 **looks over at core 2 duo system** currently running windows 11 as a cheapo test bench
well done 👍
Salam best way found board shortciruit ?
Great job🙌🙌🙌
Nice Job Sir
as always great job .. what would an apple guru have said about the unit hahha ?????
Great 💯👍🤗
i have 3 beeps for years but sometime it turns on and worked for few weeks without any issues, then , it happens again, I'm so sick of it, a laptop that only worth 80$ but have to spend 50$ on repair
Where can I mail you my laptop?
Bro seme issu but ram shake after 800 milliamperes slow step by step up milliamperes but still no display Any information you have
good job
Great 👏👏👏
woo hoo nice fix! 😅👍
thanks :) broder.
Nice 👍🏾
A handshake should be firm, but gentle. Like when holding a baby in your arms.
sorry bro, but its no problem with ram or soldering, it is cpu die, memory controller in cpu if to be precise
Yes I do think so, I repair lot of them with cpu change, and what I can tell with reball they come after months, cpu change problem solved ! 👍
You can repair a lenovo flex2 motherboard?no video
👍
Alhamdulillah 😍👍
Why don't that work when I do it on a mac mini..at 480c ...the chips don't even move. ..
Thats just a temporary fix, unless there is a water damage i see no reason to reflow the ram chip, after a weeks or a month the same problem will occur again,
This depends entirely on the cause of the issue. If it was merely corrosion this fix may outlast the machine itself. This is the simplest thing to do when you get the RAM beeps. One the Airs it's usually because the chassis is so flexible that the balls separate from the pads. You can test this pretty easily by just pressing down on the ram chips to see if they connect again.
Awesome ✌🏻✌🏻✌🏻
good job
please next time with gpu vram
Wow!...
Can you post a message first, so I don't get a spoiler reading the first message on the chat when watching the video. thanks
i reflow all rams ..but dint help..i will try 1 more time or raball ram chips if have more time

Tea lubricates the brain, that's my excuse lol.
