US 2025/0166401 A1 · HARDWARE INTEGRITY VALIDATION

Abstract

Described is a method for validating hardware integrity on a printed circuit board assembly includes receiving a sample image of a first PCBA, where the first PCBA includes a first PCB with a first plurality of electronic components. The method also includes receiving a baseline image for a second PCBA, where the second PCBA includes a second PCB with a second plurality of electronic components. The method also includes comparing, utilizing differential analysis, the sample image to the baseline image and identifying, based on the comparing, a first area of a first anomaly associated with the first PCBA. The method also includes displaying a composite image highlighting the first area of the first anomaly associated with the first PCBA.
