FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Getting Started
How to Add Operator Prompts to Hardware Tests
Operator prompts pause automated tests for manual steps. Learn how to add prompts with text input, choices, and timeouts to OpenHTF tests.
- Compliance & Traceability
Generate Test Reports for Auditors
Structure your OpenHTF tests so TofuPilot captures audit-ready records with serial numbers, measurements, limits, and metadata.
- Scaling & Monitoring
How to Compare Yield Between Lines
Compare first-pass yield across production lines to identify underperforming equipment, operator training gaps, and process variation.
- Concepts & Methodology
What Is Shift-Left Quality in Manufacturing
Shift-left quality moves defect detection earlier in the manufacturing process. Learn how it reduces cost and how test data enables it.
- Compliance & Traceability
Track Serial Numbers and Sub-Assemblies
Record parent/child serial number relationships in your test data to trace sub-assemblies across boards, modules, and final products.
- Test Station Setup
Manage Operator Certification
Track operator training, certification status and test authorization by recording who ran each test and gating on certification.
- Test Data & Analytics
Track Rolled Throughput Yield
Learn how to measure Rolled Throughput Yield (RTY) across multi-step manufacturing processes and track it in TofuPilot's dashboard.
- 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
Migrate from NI TestStand to Python: map sequences, step types, process models and callbacks, and validate the port before you cut over.
