The semiconductor test floor requires frequent load board changeovers, particularly in high-mix production environments. Manual handling of high-value Device Interface Boards (DIB) involves operational variables such as physical strain and the risk of mechanical damage. The X-change Cart by esmo group addresses these challenges by automating the positioning and transfer process. The system architecture includes a tower capable of ±90° swiveling, which allows the unit to operate within narrow corridors and constrained spatial layouts. To ensure precise alignment with various hardware, the locking mechanism supports ±180° rotation, while the Y-axis and Z-axis movements provide the necessary degrees of freedom to interface with test heads, probers, and storage racks.
Operational efficiency in high-mix environments
Technical efficiency is achieved through a structured Human-Machine Interface (HMI) controlled sequence that enables a single operator to complete a full board exchange in less than sixty seconds. The cart is designed to transport two load boards simultaneously, which facilitates a rapid exchange cycle by allowing the technician to bring a new board to the tester while immediately retrieving the one being replaced. The use of sensor-based detection and an integrated safety hand-brake ensures that the mechanical movements are controlled and repeatable, reducing the dependency on individual operator technique. Furthermore, the inclusion of a modular battery system provides the power necessary for consistent operation throughout a shift.
Technical compatibility and automation pathways
The gripper head of the system is constructed with ESD-safe materials to protect sensitive electronic components at every point of contact. This engineering choice is critical for maintaining the integrity of high-value DIBs during transfer. The X-change Cart is designed for broad compatibility with major Automated Test Equipment (ATE) platforms, including those from Teradyne, Advantest, and SPEA. This allows facilities to integrate the system into existing multi-vendor environments without requiring hardware reconfiguration. For organizations pursuing long-term automation objectives, the interface tower can be mounted onto customized Automated Guided Vehicles (AGV) or Autonomous Mobile Robots (AMR), providing a modular path toward fully autonomous test floor operations.
Exhibition and demonstration
The X-change Cart is being presented through live demonstrations at the esmo booth during SEMICON Southeast Asia 2026. The event is held at the MITEC in Kuala Lumpur from 5–7 May 2026. Technical staff are available at Booth 2145, Hall 8, Level 2 to demonstrate the system’s mechanical locking mechanisms and its integration with various ATE interfaces. The system remains available for technical evaluation by Outsourced Semiconductor Assembly and Test (OSAT) providers and Integrated Device Manufacturers (IDM) seeking to standardize their board handling procedures.
