FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Test Data & Analytics
How to Store Manufacturing Test Results
A practical guide to storing production test results: flat files, SQL schemas, STDF and ATML standards, and when each approach stops scaling.
- Migrating from Legacy Systems
WATS Alternatives for Test Data Management
Compare alternatives to WATS for manufacturing test data management, with a feature matrix, cost breakdown, migration paths, and when to stay on WATS.
- Migrating from Legacy Systems
Import Historical Test Data via the API
Learn how to backfill years of legacy test results with the runs API, keeping original test dates so trends and analytics stay correct.
- Test Data & Analytics
Record Test Conditions as Measurements
Learn how to capture supply voltages, temperatures, and other test conditions as measurements so they chart, export, and correlate.
- Test Data & Analytics
Add Derived Measurements to a Test Script
Learn how to record computed values like spreads, margins, and ratios as first-class measurements, so analytics can chart and correlate them.
- Aviation & MRO Testing
Detect Latent Defects with Fleet Test Data
Learn how to find units that pass every individual limit but carry a latent defect, using a derived measurement and fleet-level control charts.
- Quality & Process Control
Setting Alert Thresholds That Actually Work
Why a fixed yield threshold fails on real production lines, and how a self-calibrating EWMA detector finds the right band for each one.
- Aviation & MRO Testing
Getting Started with TofuPilot for Aviation MRO
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.
- Aviation & MRO Testing
Build a Reliability Case with Test Data
Learn how to turn bench measurements into a reliability case for OEM design changes, using MTBUR gaps, drift trends, and Cpk evidence from TofuPilot.
- Aviation & MRO Testing
Component Test Records for EASA Part-145
Map EASA Part-145 record-keeping and calibration rules to TofuPilot features: test records behind the Form 1, retention, backups, and traceability.
- Aviation & MRO Testing
Track Retest Counts to Catch Rogue Units
Learn how to spot rogue units early by tracking retest counts per serial number, with self-calibrating alerts on abnormal shop visits in TofuPilot.
- Aviation & MRO Testing
Avionics LRU Bench Testing and Analytics
Learn how avionics LRU bench tests work, from induction to release, and how to turn CMM test results into analytics with TofuPilot.
