Guides

Learn how to calculate first pass yield (FPY), why it matters for manufacturing test, and how to track it automatically with TofuPilot.

Build and run a hardware test in Python in 15 minutes using OpenHTF and TofuPilot, with measurements, limits, and automatic data logging.

A structured comparison of Python and LabVIEW for manufacturing test automation, with cost analysis, feature comparison, and real migration considerations.

A complete guide to PCBA functional testing (FCT) with Python, OpenHTF, and TofuPilot, covering power rails, communication, current draw, and traceability.

Learn how to backfill years of legacy test results with the runs API, keeping original test dates so trends and analytics stay correct.

Learn how to capture supply voltages, temperatures, and other test conditions as measurements so they chart, export, and correlate.

Learn how to record computed values like spreads, margins, and ratios as first-class measurements, so analytics can chart and correlate them.

Learn how to find units that pass every individual limit but carry a latent defect, using a derived measurement and fleet-level control charts.

Why a fixed yield threshold fails on real production lines, and how a self-calibrating EWMA detector finds the right band for each one.

Set up the TofuPilot CLI, write a first component bench test, and run it locally in an aviation MRO shop, with no account or proprietary data needed.

Learn how to turn bench measurements into a reliability case for OEM design changes, using MTBUR gaps, drift trends, and Cpk evidence from TofuPilot.

Map EASA Part-145 record-keeping and calibration rules to TofuPilot features: test records behind the Form 1, retention, backups, and traceability.
