The Secret VCC Grinding Method: Safely Remove an iPhone CPU Without CNC.
Рет қаралды 9,111
7 ай бұрынLearn my new technique to prep your donor board for a CPU Swap. The "VCC Grinding Method" is how you can remove an underfilled IC without damaging or bumping the surrounding components.
This method works great for CPU, BBCPU, WiFi, BBPMU, PMIC, and more! Basically, if it's underfilled & no easy way to slide your flat blade to pop it off, use the VCC Grinding method to get it off safely!
Make sure to watch the full video to understand the principle to what makes this technique work.

I'll get back to you ASAP with a quote.

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.

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
@SURGE101 7 ай бұрын
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.
@VCCBoardRepairs 7 ай бұрын
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.

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
@VCCBoardRepairs 7 ай бұрын
I've thought about that. Although that would make a ton more of a mess haha
@gizmosfix 7 ай бұрын
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.

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?
@Bvetube101 7 ай бұрын
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
