Baseline

The motor driver IC on the main control PCB of a packaging machine was discontinued (EOL). Last stock was gone; grey-market prices: €4,800 per board. Three boards in operation, one as spare. A new packaging machine: €280,000 + 4 months lead time.

Approach

Week 1

PCB reverse engineering

Full schematic extraction. All components identified. EOL IC electrically characterized (inputs, PWM, timing) using an oscilloscope during operation.

Week 2

Replacement component & design

Found a modern motor driver IC (same function, 10‑year availability commitment). Re-drew PCB layout (same form factor for drop‑in). Improved thermal design.

Weeks 3–4

Firmware & testing

Integrated register configuration for the new IC into existing firmware (no business-logic change). SOA load test. 500‑hour run test without faults.

Weeks 5–6

Small series production

Produced initial batch of 10 boards. Created pick‑and‑place program. Delivered full quality control documentation.
