Many defects do not originate during soldering – they arise much earlier, when components or pins are simply not visible to the AOI camera. Wrong angle, blocked sightline, a tiny shadow … and the error slips through inspection.
This is exactly where PCB‑Investigator’s AOI Analysis helps: It simulates inspectability during the design phase – in both 2D and 3D – so you detect issues before they become costly.
Why it matters:
- 2D Inspection:
Measures distances in expected viewing direction, considers camera angle, and reports blocked pins – before hardware exists. - 3D Inspection:
Simulates component shadows in horizontal/vertical directions. If a pin falls into a shadow zone, it’s flagged as potentially uninspectable. - Professional‑grade detail:
Pin‑level result tables, camera angle settings, tolerance controls, component‑ignore rules, color‑coded pins, shadow‑layers, import/export of result sets, and more.
Bottom line:
AOI Analysis ensures that every relevant pin is visible to your inspection systems, reduces risk, and lowers manufacturing cost before production even starts.
