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
