HannStar Display — ACME Pumps Motor Bearing Thermal Monitoring

01 The Problem

A display fab's cleanroom depends on dozens of vacuum and cooling pumps to keep the process running. Each pump motor has a bearing that gets warmer when it's loaded — and when a bearing actually starts to fail, the temperature rises faster than usual. If the operator catches it late, the pump seizes, the cleanroom process halts, and a restart plus recalibration costs over $1 million.

The Risk

Display-fab vacuum and cooling pumps' bearings, if overheated, shut down the entire cleanroom process line.

Detection Gap

Restart + recalibration loss exceeds $1M.

02 The OctosX Solution

We bond Thermalpas M-TYPE sensors to the heat-sink base of each ACME pump motor. OctosX doesn't watch the absolute temperature — it watches the delta between the bearing and the ambient room. If that delta exceeds 20°C, the system alerts maintenance to schedule a replacement before the failure.

Sensor & Edge

Thermalpas M-TYPE on every ACME pump motor heatsink base.

Cloud Logic & Alerting

OctosX Cloud monitors "bearing-vs-ambient ΔT"; ΔT > 20°C triggers alert.

03 The Outcome

A typical display fab with 50 pump motors deploys for about $250K. The math is straightforward: prevent one line stop per year and you've recovered the cost four times over. After two years HannStar reports a 400% ROI on the deployment.

Field Detection

A typical display fab (50 pump motors) costs $250K.

Quantified Impact

Conservatively averting 1 line-stop per year = $1M benefit, 400% ROI.
