Guides

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

Learn how to structure OpenHTF tests so repair loops, rework actions, and retests all link to the same serial number in TofuPilot.

PCB design for testability (DFT) guidelines covering test point placement, JTAG boundary scan, programming headers, and how DFT enables automated testing.

Learn how to automate motor and actuator production tests, capture torque, speed, and vibration data, and track results with TofuPilot.

Learn how to build a functional test specification for PCBA production, map schematic nets to measurements with datasheet-derived limits, and translate to.

Learn how to tag OpenHTF test runs with station, line, factory, and shift metadata, then compare first pass yield across production lines using TofuPilot.

Compare MIL, SIL, and HIL testing approaches with cost, speed, and fidelity tradeoffs, plus Python examples for hardware-in-the-loop validation with TofuPilot.

An EOL operator screen must be fast, clear, and error-proof. Learn how to design the interface for end-of-line test stations.

Set up hardware-in-the-loop testing for embedded systems using Python, GPIO control, and TofuPilot logging for automated regression analysis.

Structure HIL test results with firmware versions and environmental data for regression tracking in TofuPilot.

Learn how to set up burn-in tests for electronic assemblies, log results to TofuPilot, and use burn-in data to catch infant mortality defects.

Hardware reliability testing predicts product lifespan under stress. Learn what it covers, common methods, and how to track results with TofuPilot.
