That image is still highly misleading, you can see from the overlayed optical image that the CPU is not coated.
Ideally you'd want to coat any metal surface with black epoxy, and set the IR camera Emissivity Coefficient to 0.9 (the coefficient for black epoxy).
- delinka 7y agoWhy would the overlay need to be with the board that had a coating? Buy two boards, cover the parts on one board that are silver, shoot IR. Use second board for visible wavelength photo, combine for a beautiful overlay result.
- godelski 7y agoWhy would you assume that they are different boards?
- stan_rogers 7y agoIt's not an assumption, it's a suggestion for making an thermal/visible light overlay photo where the IR photo shows only emitted light.
- outworlder 7y agoWouldn't that change the heat dissipation characteristics and skew the results? Is a metal surface coated with epoxy exactly the same (from transmission, convection and radiation point of views) as a naked metal surface?
