PCB Milling reccomendations

[PaisleyPCdoctor]

I work with PCB'S and BGA's every day and I don't see why it wouldn't work. Biggest risk is ripping a solder ball off along with the on chip BGA pad. Slow plunge and a bit of care and it should be OK.

As for Chinese CNC not being up to it? What? Of course they would! It's just milling a bit of pcb and copper.

In fact- why do you need a CNC at all? For 10% of your budget you could get a basic manual mill/drill press. With micrometer depth adjustment, just step down, move it around xy axes, then down a bit more. Again- you don't need cnc for this- basically you just need control of the z (plunge) depth.

Want me to remove a BGA through the PCB? I can post a video to let you see how it goes.
I use a China 6040 that I've owned for 2 weeks and I KNOW it can be easily done.

Edit... Obviously the pcb will be destroyed, but as I understand it- you just want to salvage the usable chip, right?
