Just finishing my MSC and looking for title for my dissertation 😯 . I'm interested in doing something that may be interest to others. I am contemplating looking at methods on removing the internal eeprom memory chip and reading the data particularly when the phone is damaged. Has any had success in doing this ? Obviously the process will be phone dependant. Often seen it mentioned in papers but never really the process or the tools required – highly likely I’m just looking in the wrong place oops …does anyone have any sources of information, or is it something that is never really carried out due the expense and lack of results.
Any comments will be appreciated…many thanks J

We do this occaisionally.

Its getting harder and harder because of the way the chips are set into the boards. PGA, PQFP were relatively simple, but the new PBA set chips are harder if not impossible to remove securely, (so that they can be read again).

The older the equipment the easier.

Most of our stuff is done by hand, (dry air soldering station), jewelers magnifying glass etc, however, there is kit available - at a cost.

I hope this helps?

Regards,

Simon

Simon,

Would you be so kind as to elaborate on the "kit" and its cost?

Thanks, in advance.

For larger chips, Infra-Red heater/solderers are better, but as we predominantly use our kit for phones and hard drives, then we use a Xeltek Super Pro 3000U eprom reader, (with hundreds of adapters) adn a Xytronic 850D hot air solderer.

As for the price GIYF!

Regards,

Simon

PS Its the person using the kit knowing what they are doing that is the issue, not the kit!
