Project Overview

Motionwell Automation delivered a series of cleanroom-grade Automatic Test Equipment (ATE) machines (Project P23018) for electronics manufacturers in Singapore. The ATE series performs mechanical and electrical testing of electronic components, connectors, and sensors within ISO Class 7/8 cleanroom conditions.

The project addressed the need for automated, repeatable testing with full data capture, replacing manual test processes that introduced human variability and limited throughput.

System Design

Cleanroom Integration

Each ATE machine is fully enclosed with 4-6 FFU (Fan Filter Unit) modules that maintain ISO Class 7/8 cleanroom conditions:

  • HEPA-filtered air circulation within the test enclosure
  • Positive pressure maintenance to prevent particle ingress
  • Material selection compatible with cleanroom protocols
  • Easy-clean surfaces for routine maintenance

Multi-Station Test Architecture

The ATE uses a circular transfer system with multiple test stations:

  • Automated component loading via collaborative robot
  • Sequential test execution across stations
  • Real-time pressure and displacement monitoring
  • Automated pass/fail sorting based on test limits
  • Data logging in SPC-ready format

Cobot Loading System

A collaborative robot handles automatic loading and unloading of test specimens:

  • Tray-based batch loading for high throughput
  • Vision-guided pick-and-place for precise positioning
  • Dual tray system for continuous operation (load while testing)
  • Automatic sorting of tested parts by result

Challenge

An electronics manufacturer needed automated test equipment for connector insertion/withdrawal force testing and cable bend fatigue testing within ISO Class 7/8 cleanroom conditions. Manual testing introduced variability and limited throughput.

Solution

Motionwell delivered enclosed ATE machines with 4-6 FFU fan filter units for cleanroom compliance. Multi-station circular transfer with cobot auto loading/unloading. PLC-based control with Siemens HMI, real-time pressure and displacement monitoring, and SPC-ready data logging.

Outcome

Consistent, repeatable test results with full data capture for SPC analysis. Cleanroom environment maintained throughout testing. Cobot loading eliminated manual handling and improved throughput while freeing operators for higher-value tasks.
