Rotation Heuristics in SMT Assembly: Why We Still Guess, and How IPC-2581 Fixes It

A 180-degree rotation error on a polarized capacitor causes a short circuit. A three-tier heuristic system catches most of them. The IPC-2581 standard would make the whole problem obsolete.

Simulating Physics in Python: Vacuum Nozzle Validation for SMT Assembly

Every component on a PCB has a physical body width. Every nozzle has an outer diameter. If the nozzle is too large, it drops the part. Here is the 1,600-line async pipeline that validates this at scale.

Closed-Loop Manufacturing: Cross-Linking AOI and SMT Machine Telemetry

An optical defect and the machine event that caused it happen minutes apart and live in separate databases. Time-windowing SQL joins close the loop — here is how.

Why I Killed My 240KB Excel Macro and Built a Full-Stack MES Instead

Every manufacturing team has that one Excel macro — the one nobody touches. Here's why I finally killed ours and what I built instead.
