Alex, I want to thank you for everything that you are teaching us. It has been a wonderful thing to stumble upon your channel and I have learned alot in recent months.
After watching your videos for a few months I have successfully replaced an M.2 slot for a WiFi card in a laptop with a slot from a donor board using everything that I have seen you do.
The slot is made of plastic and it has a row of through hole pins and one of surface mount pins. I first applied leaded solder to the pins, along with Amtech 559 flux (from eBay in the UK but seems to be the good one), then I applied heat from the back of the board and the slot came out without any damage to the pads or the slot. I did this twice, once for the damaged slot and once for the good slot from the donor board. After this I cleaned the board with IPA, added fresh flux and used solder wick to clean the holes and pads and they came out perfect. I've then put the good slot in, added fresh flux and using leaded solder I soldered every pin without any bridges. After cleaning the board with IPA again, it came out better than factory with nice shiny joints and it works perfectly. So thank you again for sharing your knowledge and experience freely with us!
PS. I did all of this withought a microscope, I was using a magnifying glass from time to time.
It's very difficult to do the work without a microscope. Great job.
Watching a true soldering/de-soldering master at work is just awesome. Brilliant work again. Alex :)
Nice job (love from India)
THIS MAN KNOWS WHAT HIS DOING ..AND HIS A PRO AT WORK 👍👍👍
Awesome repair, that Tri-Star Chip is so tiny. You always make it look easier! Thanks for sharing!
well, im not used to comment oon videos but this i have to.
i really like how alex explaines the difference between tools and how to use them, i like the fact that he is doing his job and explaining and teaching at the same time.
i really enjoy watching your videos and i learned a lot from you, and im excited for your courses
i wish you all success brother
Setting up a block of sal-ammoniac for keeping your solder tips clean would be a good idea.
Great Show!!
Your flux does a really clean job on the board. Others who use cheap flux have motherboadrs that are very ugly after repair. Nice.
Awesome work, greetings from the UK.
Thank you for your kindness of sharing and generosity of your technological knowledge.
Did you check pin number 4 after the job was done to confirm the no number reading?
Great job. I love your videos.
I am always amazed at you skills in diagnosing what the problems are.
Very good work, alex. Better than factory. Great video and as always good explainings. Greets
to remove glare i find turning down the ring light works, having another light also on the work space for lighting. great vids. i do lots of these repairs too :-)
Beautiful work.
Great work. Determination, skill and Knowledge
Awesome content as always! Looking forward to the upcoming anti glare video👍🙂
good
Yes .. please . make a video on how to get rid of glare .. it will be very helpful.
This is one of the biggest mistery for me still, how to get rid of the reflection. I have them even with spot lights. So I ordered polarizer with integrated ring light on aliexpress. Please make a special video how to use microscope that you are selling and how to improve picture quality by playing with light🙏
Better than factory. As usual.
Nice one boss
Great Job as always
Job is done!
Awesome Alex
Very nice repair 👍🏾
For so many reasons i know it the other way. As a Dj youre Mix is working perfect. When you hit the Record Button - nothing is perfect anymore 😂✅
Pretty amazing stuff. How much was that repair?
Nice Repair
This may be nothing, could be the camera moving around or something(hard to tell), but at about @10:17, the chip labeled XW CD in the frame to the right of the tristar chip appears to be knocked *veeeeery* slightly askew, maybe by a half a degree counterclockwise. Not sure if this would unseat the chip or cause any problems at all, it was just something I happened to notice. 🤷♂
Looking at it again, I'm relatively certain it's the chip itself moving and not the camera or a shadow and it's the only thing on the board that appears to move in this shot.
Hot tweezers are really great idea!
Curious if you purchase new popular products to use as reference when you need to compare values.
I always wanted to ask you, how do you get rid of the glare, is that a camera function?
Obs. Hahaha, I asked before you mentioned. Thanks.
Nice job 🙏👍
Hello. Been subscribed to your channel for a long time. I really like your work. I need to ask you something. If possible, sign the temperature of the hot air station in the corner of the roller. I lack experience and your experience would be useful. Thank you.
May God bless you always 🙏 love you 🙏💖💖
You can also test a tristar chip with your dc power supply
Good job love from srilanka
Can we used that tristar tester to test the Android phones?
How do you properly maintain your soldering tips? I for the life of me can't make mine last very long, I clean them frequently, reapply fresh solder, yet they always become oxidized after a 2-3 times of turning it on.
Do you store them with solder on the tip even when cool?
How to trace a line if many capacitors are shorted.
What level of air and temperature do you use?
Hey Alex
Did you charge the customer for tristar chip or not?
Can you suggest me a cheap and good termal camera?
nice Vedio ☮️👍
Came in for repair.
How hot do you set your soldering iron when desoldering?
If I had to guess, I'd say very hot
Alex , what kind of flux you apply for remove the connector and the small BGA IC ? Are they is same type ?
hay hussain, is big boss your relative or just employee....
Please how do u detect a bad multiple capacitors close to the ram
What do you do with a plastic black cover over the connector that you removed ?
Did pin 4 have any reading after the cable replaced?
Awesome ✌🏻✌🏻✌🏻
👍
Amazing 👌
btw why not using FLUX at 06:30
any specific reason for that?
He only needs the component hot enough to remove it
I have a similar condition after update, first it showed different charge after every lock , then it started restarting every 2.45 seconds , then after I forced the ipad to go down to 1 percent , the ipad won’t charge and would only boot with power.
I have a type c charger and can’t plug into my windows pc for a iTunes repair or update.
I am not in a situation to buy a usb to lightning wire and I need the data in the ipad 🤦🏻♂️
I hope I can solve this puzzle.
Nothing was wrong with the tri-star chip to begin with as long as all the battery pins not making a good connection it's going to randomly restarts or not charge pass certain %
Hello Alex! Why do you (and other technicians) always touch the chip after is has clearly seated in place? Are you trying to detect solder bridges or something like that? Thanks! :)
I'm not Alex, but it is because looks can be deceiving. Just because it looks like it is in place doesn't mean it is in place. Reflowing and slightly touching the chip verifies that each solder ball is in connection with its own pad on the array. The melted solder balls under the chip has its own tension or pull towards its own pad (when melted), so when he touches the chip, the melted solder balls pull to their designated pads on the board seating the chip perfectly.
No user-serviceable parts inside. I've been doing electronics for 50 years and dread touching those things, what makes a do-it-yourselfer think he can do it?
What is 'low melt solder'? is that just normal leaded resin core solder?
Low melt solder, also sometimes called "Chip Quick" is a type of solder that melts at around 138°C.

Battery connector srew loose
I have a new I pad here it's my friends dads he broke the touchscreen and attempted to replace it. Now the I pad turns on but no picture we have backlight but just a black image. Anybody know what this could be filter etc ? Thanks in advance for any replies
Maybe filter, maybe bad display.
Was that display an Original or from aliexpress?
I need to stop watching your videos. The moment I apply flux, you pop up in my head saying "Flux is your friend" and there goes my plunger......
3rd good morning
first
Well done. As always
Will be nice to know your way to get rid of the glare really.
microscope light is vertical with 90 degree angle. just use an external light with some angle(not vertical). change the angle of the light until you satisfied with the result. I think this is what he is doing.
Excellent 👍
