FIELD NOTES
Get better at hardware test.
Guides, tutorials, and best practices to help you build better hardware tests.
- Test Station Operations
Realtime and Deploys on Self-Hosted TofuPilot
Add the Centrifugo realtime server and the Docker-in-Docker deployer to a self-hosted TofuPilot instance for live status and Git-push deployments.
- Migrating from Legacy Systems
Migrate OpenHTF Scripts to TofuPilot CLI
Run existing OpenHTF scripts on the TofuPilot CLI with no rewrite, and decide which ones are worth porting to the TofuPilot Framework.
- Getting Started
Why TofuPilot Needs Administration: write
Learn why the TofuPilot GitHub App requests Administration: write, what it enables, and how to scope it safely with selected repositories.
- Quality & Process Control
What Is a Histogram in Manufacturing Test
A histogram shows the distribution shape of your measurement data. Learn how to read histogram patterns, spot problems, and use them for SPC in TofuPilot.
- Quality & Process Control
Cpk vs Ppk: What's the Difference
Cpk and Ppk both measure process capability, but use different standard deviations. Learn when to use each, what the gap reveals, and compare them in TofuPilot.
- Quality & Process Control
What Is Ppl and Ppu (One-Sided Performance)
Ppl and Ppu measure long-term process performance against individual spec limits. Learn the formulas, how they relate to Cpl/Cpu, and track them in TofuPilot.
- Quality & Process Control
What Is Cpl and Cpu (One-Sided Capability)
CPL and CPU measure capability against a single specification limit. How to calculate them, when to use them, and how to record one-sided measurements.
- Compliance & Traceability
Data Sovereignty for Manufacturing Test Data
Learn why test data jurisdiction matters for manufacturing companies and how to protect process parameters and yield data from foreign surveillance laws.
- Quality & Process Control
What Is Pp (Overall Process Performance)
Pp measures long-term process spread relative to spec width using overall standard deviation. Learn the formula, compare Pp to Cp, and track it in TofuPilot.
- Quality & Process Control
What Is Ppk (Process Performance Index)
Ppk measures long-term process performance using overall standard deviation. Learn how it differs from Cpk and how TofuPilot tracks both.
- Quality & Process Control
What Is Cp (Potential Process Capability)
Cp measures how much of the spec window your process variation uses, ignoring centering. Learn the formula, how Cp relates to Cpk, and read it in TofuPilot.
- Quality & Process Control
What Is Cpk (Process Capability Index)
Cpk measures how much room a process has inside its specification limits. How to calculate it, what the values mean, and what invalidates it.
