FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Test Data & Analytics
What Is First Pass Yield and How to Track It
Learn how to calculate first pass yield (FPY), why it matters for manufacturing test, and how to track it automatically with TofuPilot.
- Test Data & Analytics
What to Log in a Production Test
The fields worth recording in a production test so failures are still debuggable six months later, and the four that are painful to add afterwards.
- 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.
- 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.
- Test Data & Analytics
What Is Test Observability
Test observability gives full visibility into what your test systems are doing, why they fail, and how they perform. Learn how it applies to manufacturing test.
- Test Data & Analytics
How to Detect Measurement Drift
Learn how TofuPilot grades measurement drift against each series' own baseline, and how to write tests that make a real shift visible early.
- Test Data & Analytics
Hardware Test Observability
Learn how to build full observability into your hardware test operations using TofuPilot's dashboards, alerts, and analytics.
- Test Data & Analytics
Analyze Test Step Performance
Learn how to break down test performance by step to find which phases fail most, run slowest, or have the lowest Cpk using TofuPilot's step analysis.
- Test Data & Analytics
Test Data Visualization for Hardware Teams
Learn how to build dashboards and visualizations for hardware test data using TofuPilot's built-in analytics and charting tools.
- Test Data & Analytics
The True Cost of Poor Quality in Electronics
Understand COPQ categories, the 1-10-100 rule for defect costs, and how proper test coverage with TofuPilot catches issues before they become expensive.
- Test Data & Analytics
Export Test Data to Power BI
Learn how to export test data from TofuPilot to Power BI using CSV exports and the REST API for custom management reports and cross-system analysis.
