FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- 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
Semiconductor Wafer Test Data
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
Reference for SCPI commands in Python with PyVISA: measurement types, triggering, error handling, and wiring instruments into a TofuPilot procedure.
- 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
Map IATF 16949 requirements for production test records, MSA, and control plans to TofuPilot's traceability and analytics features.
- Concepts & Methodology
Automated Verification and Validation
Learn how to automate hardware verification and validation workflows using TofuPilot for structured test evidence and traceability.
- Test Types & Methods
EMC Pre-Compliance Testing: A Complete Guide
Learn how to set up EMC pre-compliance tests, log radiated and conducted emissions data, and track EMC margins with TofuPilot.
- Concepts & Methodology
Build a Test Data Strategy
Define what test data to capture, how to name procedures and measurements, and how to organize everything in TofuPilot for long-term traceability.
- Test Types & Methods
What Is AOI, SPI, and AXI in PCB Manufacturing
AOI, SPI and AXI are the automated inspection steps on an SMT line. What each one catches, where it sits, and how to trend the results.
- Test Data & Analytics
Set Measurement Limits from Prod Data
Learn how to derive statistically sound measurement limits from production data using the 3-sigma method, detect distribution anomalies, and configure.
