Hello great video like always ! I Have a tips if you want : sometimes i damaged the cpu when cleaning it. Now i use preheater for clean cpu with MaAnt SL-1 at 250 degrees and i remove the black pasted with metalic brush and classic brush. I find this more sure. (Sorry for my english). Have a nice day !

You hit the nail on the head when you said that some damage created by techs is just not fixable or proffitable to fix. It is super hard to learn a new skill when youre busy like you said, so repair shop owners and techs need to know when to cut off a repair and send it off to a proffessinal that has the capability to continue the repair. So important.

Thank you for the video. I attempted the same reball job this week! It was my first CPU reball. I ended up with a shorted GPU line inside the CPU. Do you think too much heat might have caused that? Or Maybe i damaged if from clamping it in a vice? I used the "IBrush Steel Brush (Qianli)" from mobile sentrix to clean the cpu. Low Melt + Flux + Hot Air + Steel brush to clean the cpu and that worked really well and got everything shiny clean and looked like new. Saw Dr. Ben use this method...

I'm still a little to scared to lift a CPU for a repair, I have tried a few times, but I just haven't been able to do it properly and consistently enough to be able to do it to a customers device. As you say, It's very easy to rip the pads on the CPU, Too many times have I done a perfect pull, but in the under fill removal process, I have lost some critical pads. I have seen chemicals out there to loosen the under fill on the CPU. I'm not sure if they work well or not though, as I have not seen anyone use any. I would love to learn about android phones, Not just connector repairs or simple short fixes, But stuff like CPU swaps, UFS, EMMC repair, Using easy jtag or Z3X box for repairing IMEI things like that? Also, side note, Your not old, there's just not been any really good games for mobile in the last 10 years, that's why its still just minecraft, roblox, fortnite etc hahaha

It’s impossible to reball a cpu. When I do it, 10% of the balls solder to the stencil. Reballing is stressful. I exactly did what you did.

@VCCBoardRepairs 4 ай бұрын

You need more practice.

@carmelorossitto7084 4 ай бұрын

@@VCCBoardRepairs, I have been practicing hard for more than one week but the result is the same. It was 20% of balls in the stencil. Now 10. Maybe next time 0. I will continue to practice.
