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
Build Your First Hardware Test

Build and run a hardware test in Python in 15 minutes using OpenHTF and TofuPilot, with measurements, limits, and automatic data logging.

Getting Started
Python vs LabVIEW for Manufacturing Test

A structured comparison of Python and LabVIEW for manufacturing test automation, with cost analysis, feature comparison, and real migration considerations.

Migrating from Legacy Systems
PCBA Functional Testing: A Complete Guide

A complete guide to PCBA functional testing (FCT) with Python, OpenHTF, and TofuPilot, covering power rails, communication, current draw, and traceability.

Test Types & Methods
Migrate a Station from v1.0 to TofuPilot CLI

Move a test bench from the v1.0 desktop station app to the TofuPilot CLI: one-command install, automatic deploys, and a live operator UI.

Migrating from Legacy Systems
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.

Test Station Operations
Migrate OpenHTF Scripts to TofuPilot CLI

Move OpenHTF scripts from the legacy with TofuPilot wrapper to the TofuPilot CLI runner with deterministic deploys, station auth, and live UI.

Migrating from Legacy Systems
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.

Getting Started
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 process capability against individual spec limits. Learn the formulas, when to use one-sided indices, and how TofuPilot displays them.
