The Assignment
SenseAir (now Asahi Kasei Microdevices) manufactures world-leading CO₂ and gas sensors in Delsbo, Sweden. They needed a modern test executive system handling both production testing and characterization with high throughput.
Delivery
Test Executive
Sequence-based test system with parallel execution, timeout handling, and automatic retry.
Hardware Interface
Drivers for measurement instruments, gas flow control, temperature chambers, and DUT communication.
Data Collection
Real-time logging of all measurement points with statistical process control (SPC).
Reporting
Automatic generation of test reports, trend analysis, and scrap statistics.
Results
Test capacity increased 300% without additional staff. Automated SPC catches process drift before it affects final product quality. The system still runs in production today with 99.9% uptime.
