FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Test Data & Analytics
What Is Test Data Management
Learn what test data management is, why spreadsheets fail at scale, and how TofuPilot structures your electronics test data automatically.
- Test Data & Analytics
The Hidden Cost of Retesting in Manufacturing
Learn how retesting inflates costs in manufacturing, identify root causes, and use TofuPilot's unit history to track and reduce retest rates.
- Test Data & Analytics
How to Build Manufacturing Test KPIs
Learn how to structure your OpenHTF tests so TofuPilot automatically generates manufacturing KPI dashboards with FPY, throughput, Cpk, and failure analysis.
- Scaling & Monitoring
Hardware Test Infrastructure
Learn how to build scalable hardware test infrastructure using TofuPilot as the data backbone for test stations, instruments, and automation.
- Migrating from Legacy Systems
Migrate from NI TestStand to Python
A practical guide to replacing NI TestStand with Python and OpenHTF for manufacturing test, with step-by-step migration patterns and TofuPilot integration.
- Concepts & Methodology
What Is Zero-Defect Manufacturing
Zero-defect manufacturing aims to prevent defects rather than detect them. Learn what it means in practice, what it requires, and how test data supports it.
- Scaling & Monitoring
Test Acceleration for Hardware Teams
Learn how to accelerate hardware test cadence using TofuPilot to identify bottlenecks, reduce debug time, and optimize test coverage.
- Compliance & Traceability
Build Full Unit Traceability
Link every test result to a specific serial number and track each unit's complete test history through its production lifecycle.
- Test Types & Methods

Learn how to track wafer-level and final test data for semiconductors using TofuPilot for CP/FT yield analysis and bin mapping.
- Instrument Control
SCPI Commands in Python for Test Engineers
A reference for SCPI commands in Python using PyVISA, covering measurement types, triggering, error handling, and OpenHTF integration with TofuPilot.
- Concepts & Methodology
What Is FMEA for Manufacturing Test
FMEA identifies potential failure modes before they happen. Learn how to apply FMEA to manufacturing test processes and track corrective actions with TofuPilot.
- Compliance & Traceability
Test Traceability for IATF 16949
