Test Step Insights and First Pass Yield

August 28, 2024

Building in-house test analytics is resource-intensive. TofuPilot's new Test Step Insights module gives you manufacturing test analytics out of the box: plug-and-play, no dashboard development needed.

The module helps you identify real issues and separate them from false failures caused by test errors. Here's what it covers.

First-Pass Yield at Step Level

First-pass yield is the key metric for test system quality. TofuPilot now provides it in real-time, broken down by step, so you can spot which steps cause the most failures.

The module also ranks steps by priority so you know where to focus first.

Limits Accuracy & Deviations

Many tests require comparing measured values to precise limits. TofuPilot now automatically computes how well each step meets its limits, giving you a clear view of your procedure's process capability.

This makes it straightforward to spot incorrectly set limits or sudden deviations.

Test Duration Analysis

A breakdown of each step's duration helps you identify the time-consuming steps slowing down your test benches.

No code changes needed. These analytics appear automatically for any procedure with numeric steps.
