I like this method. Seems to be working well. A bit risky if your hand is not steady. I personally would prefer to lift the entire chip at once but i have never done that on a phone so maybe your ways makes more sense.
The way to avoid messing up the PMIC when removing the CPU is to heat the CPU area with the nozzle far away. Bring in the nozzle closer in the last 15 seconds to remove the CPU. This way the PMIC on the opposite of the board doesn't get too much heat.
One of the most frustrating things for me is prepping a donor board… I don’t know what to say about this technique of yours, doesn’t seem to save time. I’m doing it the normal way, BUT I have ordered an Aixun cnc machine which is dirt cheap. I need it for displays but am curious if it would be of any help for cpu removals
I wouldn't say this is more about saving time, but more about being able to safely remove the chip without disturbing the surrounding components. I often bump resistors & whatnot. I found i've had better success with grinding the chip off instead. A CNC of course would be the best option for this stuff but it also costs a lot more & requires some knowledge to know how to run it, calibrate, etc.
Type as us in tge search "mr. frank liu: cpu new skill- saft & fast". I tried it and it was and cpu wasnt only thing is that for some board it might ne hard to get the right spot to lift

Do you re-use your donor boards, for multiple data recovery jobs? Like, do you prep them to this point, and then transfer NAND/CPU, and then recover data, and then remove NAND and CPU, and then reuse the board for your next job?
@@VCCBoardRepairs fair 😂😂😂 do you know what it stops working, from a physical standpoint? Does heating and cooling the board dozens of times, cause internal traces to fail? Or other chips?
I would believe if you're using correct temperatures which you are used to on your hot air and soldering stations, the PCB should be able to take as many hits as it requires (until it stops working of course) If you just wack blast full heat all the time exposing the board to constant high temps, you then end up risking delamination of the inner layers within the board and because of the board bowing, your IC chips and components may not sit right when you put them on it
What about grinding full cpu like lcd touch ic grinding.takes more time in grinding but main purpose should be lesser time of heat applied.just an opinion i prefer lifting complete cpu at once
Great Video, Thanks. That tool seems a little brute force to be free handing , the potential damage if things go wrong makes me reluctant to try with it. I've used / seen similar destructive techniques but not on cell phone yet.
I'm sorry, I need more context... Why does removing a CPU involve cutting tools all of the sudden? What ecosystem is this even? On PC the CPU just comes right out... Is this some kind of console or what??
great job. i have been following your videos for almost a year now , you are doing a good thing , it hooked me up so bad that i have established a lab at my home, it wasnt easy at the beginning due to lake of knowledge and experience but i learned a lot from your videos, thanks once again. a video for the beginners is highly recommended about tools. because at the beginning i failed more than 50 times and realised cheap tools are not going to get this kind of job done successfully thanks once again much respect ❤ 🫡
Flood with with alcohol next time while grinding.
It will keep chips away and it will cool it so that grinder does not gum up.
the GPU master
I really like the opening sequence showing the work preview
I always forget to add it to my other videos lol
38:31 thats what I like about your videos. you talk and expalaine everthing u do! :)
I appreciate that!
Nice method Jesse, I’m definitely going to be trying this out. Love seeing new approaches and methods. Thanks for the share. Great watch.
Glad you enjoyed it!

What are you doing here??? Lol Just kidding Nice to see the community interact with each other's channels.
Yeah it definitely requires steady hand skills. I find it helpful for underfilled chips that are tough to slide the flat spatula tool to pop it off
This method is very common at iran. Like change the LCD chip you need this to remove the chip from new LCD without burning it. Nice job Jesse 👏
Oh that's cool to hear!
Thanks for the tutorial 👏👏
No problem 👍
I really love your work, I would appreciate if you take us through full swap
Ok I will do it soon!

The information you provide is truly amazing. Thank you
Glad you think so!
big man ! another awesome video! gracias mano for the knowledge!
Thanks for watching!
Time to test this on an iPhone X I’ve had on my table for a while now
😊
Nice 👍🏽
Great! Let us know how it goes!
Great technique!!!
Thank you! Cheers!
when iphone is iCloud locked does cpu change remove Icloud and it will be icloud unlock?
technically yes
practical, no
Awesome stuff! Super cheap cnc 😁
Glad you agree! haha

I’ve seen those manual aixun cnc machines. You’re right they look brilliant.They look great for the money and look really easy to use as well.

What liquid you use for cleaning pcb?
⭐99& Isopropyl Alcohol: amzn.to/46blbnT
⭐Needle Drip ISO bottles: amzn.to/3QRCIgj
@@VCCBoardRepairs currently unavailable 🤦🏼♂️
So let’s say you are IC swapping a board. Does the FaceID for the donor board work or for the original board. Thanks in advance.
No, Face ID sensors are paired to the CPU not the PCB board
Fonekong technique is pretty fast n if done right can also save surrounding components
i guess i'm not familiar with what the "fonekong technique" is
@@VCCBoardRepairs if I find the video again all add the title of the video so you can review

I tried your technique with the pmic. And i can say I love then results way. Use way less heat
Great video🔥 When are you gonna upload the CPU remover / swap
Soon... Soon
Nice job ❤ I like to ask you where did you buy the Handel do you use with the blade 11 ? Can you give me the link? Thanks

Yes! You can reuse them multiple times
@@VCCBoardRepairs when do you stop reusing them? :) do the pads wear down after a dozen or so removals / installs?
When it stops working lol

Ive had 3 of those grinders and they never last more than a week or two before the plastic head breaks :(
That's weird! We've been using this one for a few months now with no issues. We grind down a lot of stuff regularly
What about grinding full cpu like lcd touch ic grinding.takes more time in grinding but main purpose should be lesser time of heat applied.just an opinion i prefer lifting complete cpu at once
I've thought about that. Although that would make a ton more of a mess haha
Great Video, Thanks. That tool seems a little brute force to be free handing , the potential damage if things go wrong makes me reluctant to try with it. I've used / seen similar destructive techniques but not on cell phone yet.
Yeah it's definitely not for a beginner to try. But with a little practice, it's easy to handle.
Cnc is the best
yes of course. this is an alternative method
👍👍👍👍👍
Thank you! Appreciate the support!
❤❤❤
Appreciate it! Thank you so much
Why don't use a cnc machine?
#1 Expensive.
#2 Requires different set of skill/knowledge.
Exactly @northwestrepair
This is the poor man's method 😂
Did you just fail? Your title says “without CNC”, but obviously you just used a tiny grinder.
CNC is a big expensive machine.
Grinding pen is $20 and done by hand.
Those are 2 different things
@@VCCBoardRepairs really sorry about it. I took it back. 🤝🏻
I'm sorry, I need more context... Why does removing a CPU involve cutting tools all of the sudden? What ecosystem is this even? On PC the CPU just comes right out... Is this some kind of console or what??
It's an iPhone 8 Plus. The CPU is soldered on and glued to the motherboard
@@VCCBoardRepairs Thank you! -- Next time if there is a little bit of context earlier in the video, it will be a lot less confusing for us.
I do explain all this in the video 😅
@@BrainSlugs83next time watch the video
This is literally the worst way. Just use a grinder in a stand.
I can thinking of worser ways
Skip.😄
Waste of time
