| In short, I focus on chips that are of interest to me. I do lots of chips for others, but I give priority to people that are able to provide funds. This section is written with open source projects as the main audience, but note I also offer services through my embedded security consulting service. | In short, I focus on chips that are of interest to me.

| Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). Similar issues with staining and lapping. | Delayering is typically more risky to the chip and myself (toxic chemicals like hydrofluoric acid). Similar issues with staining and lapping. | ||

| Other: most of the work is in decapping, not actual imaging. If you happen to already have a bare, clean die and would be satisfied with a quick / lower quality scan, feel free to send me a few dies. This also can work out well since most of the NRE cost is in the microscope, not the decapping supplies. | Other: most of the work is in decapping, not actual imaging.
