Does anyone know a company in the USA that can do 3D X-Rays for USB Flash Drives inexpensively? Best quote I've gotten is $900. |

Some monolithic chips aren't exposing all the signals on the top layer of the PCB requiring me to dig through the PCB for a signal, having an X-Ray gives me an idea of where the signal is. The problem is it's challenging to get a clear x-ray with older techniques on 4 layer PCB's. |

Might be cheaper to buy up to half a dozen devices of the same and do the sand back and map the layers method. I know this is pretty time consuming and tricky, but $900 is definately not going to be viable. or use someone like these guys https://www.pcbic-reverse.com/ I used a comany called break-ic to get the hex file of an aftermarket chip that would disable the restrictions of late model holden commodores entertainment controllers. like the no-play of video while car was going over 15km p/h and a few other things. I think it was $200 |

I know this is pretty time consuming and tricky, but $900 is definately not going to be viable. The trick is finding a half dozen identical monolithic drives, its difficult enough finding one. I could always decap a donor but it would be destructive and messy, I'd much rather have a non invasive method to use on a clients drive.

I am not sure external x-rays scaning are safe to data stored in flash memory: >>> X-rays can erase programmed bits in a flash chip (convert programmed "0" bits into erased "1" bits). Erased bits ("1" bits) are not affected by X-rays |

Erased bits ("1" bits) are not affected by X-rays That may be true. Maybe we could use a donor to get a 3d map or gist of the circuit, even if the X-Ray killed it. |

The dentist in my building will do xrays for me from time to time at no charge. Tho we are friends. If you are friendly with your dentist maybe he will do them for you once in a while. I checked prices for x-ray machines and they are far too expensive |

Dentist machine is not so expensive. It cost about 3000-5000$. But quality is not so good. |

You need someone with a microfocus x-ray source to do this -- regular dental/medical x-ray tubes won't show you much of anything useful. Also, I wouldn't be too worried about these x-ray sources causing any data problems with the flash. You typically need higher than 150-175KV x-rays before you'd start getting up into the range where it's likely to cause issues. Most microfocus tubes don't run that high, nor would you need to. In terms of getting 3D, do you need actual 3D reconstructed views, or do you just need a handful of views from different angles (or parallax)? There are machines from Agilent and Nordson DAGE that can do real 3D reconstructed X-ray images, but you may get charged a bit for time on those. |
