Modular Test Slices for Concurrent Multi-User ATE Control

The test head is divided into multiple independent slices, each with its own controller computer system. This segmentation allows different slices to be controlled by different users simultaneously, enabling multi-user operation while maintaining centralized control through the ability to coordinate between slice controllers. Each slice can operate independently with its own test plan, eliminating the single-user limitation.

The system transitions from static synchronized operation to dynamic independent operation. Each slice controller can execute different test plans at different speeds based on the specific requirements of the devices being tested. This dynamic approach allows slices to operate autonomously without waiting for others, maximizing resource utilization and throughput while maintaining system coordination through the modular architecture.

The test chamber is divided into multiple independent slices, each with its own controlled environment. Users can access specific slices to load or remove devices without disrupting the environmental control of other slices. Each slice maintains its own stable environment while allowing selective user access, resolving the contradiction between environmental stability and user accessibility.

Each slice is designed to be universally applicable and can independently execute different test plans for different types of devices. When one slice has idle capacity due to insufficient DUTs, other slices can continue operating with their assigned devices. The modular architecture allows idle slices to be reallocated to different test plans or users, ensuring that expensive electronics remain productive through multi-functional utilization.
