Test station optimization reduces cycle time and increases throughput. Learn how to identify bottlenecks and improve station performance with TofuPilot.
- Concepts & Methodology
What Is Autonomous Test Closure
Autonomous test closure uses AI to determine when a unit has been tested enough. Learn how it works, where it applies, and what data it needs.
- Test Types & Methods
Write a Functional Test Spec for PCBA
Learn how to build a functional test specification for PCBA production, map schematic nets to measurements with datasheet-derived limits, and translate to.
- Scaling & Monitoring
Scale from 1 to 100 Test Stations
Architecture guide for scaling test infrastructure from 1 to 100 stations, covering naming, script distribution, config management, networking, and monitoring.
- Test Data & Analytics
How to Detect Measurement Drift
Detect measurement drift before it becomes scrap: what drift looks like in test data, which signals to watch, and how to catch it early.
- Scaling & Monitoring
Calculate ROI of Test Automation
Learn how to build a business case for hardware test automation and measure ROI using TofuPilot's yield, cycle time, and defect data.
- Test Types & Methods
Track PCBA Results Across Lines
Learn how to tag OpenHTF test runs with station, line, factory, and shift metadata, then compare first pass yield across production lines using TofuPilot.
