In high-mix semiconductor test environments, load board changeovers are a frequent and operationally significant activity. The reliance on manual handling has long presented challenges around changeover time, operator safety, and the risk of damage to high-value boards.
“Across test floors, we kept seeing the same pattern,” said Josef Weinberger, Head of Business Unit, esmo semicon. “Board changeovers were slow, physically demanding, and too dependent on individual technique. In tight spaces, that‘s where mistakes happen and time is lost. That observation drove us to build a dedicated solution that makes changeovers fast, repeatable, and manageable by a single operator in under a minute.”
Engineered for the modern test floor
The X-change Cart removes the physical demands and variability of manual board handling from the equation entirely. Through a structured, HMI-controlled process, a single operator can lock, rotate, and transfer a board to the tester within a minute. The ability to carry two boards in a single trip makes that timescale achievable in practice. Thoughtful design details, including a ±180° rotation at the locking mechanism and a ±90° tower swivel, address the real-world constraints of a busy test floor.
Broad compatibility with leading ATE platforms (e.g. Teradyne, Advantest, SPEA and more) facilitates integration into existing multi-vendor environments without reconfiguration, allowing OSATs and IDMs to realise multiple benefits without disruption to their current setup.
For facilities with longer-term automation objectives, an optional configuration allows the interface tower to be mounted onto a customized AGV or AMR, providing a practical upgrade path toward autonomous test floor operations. The modular design further allows additional features to be incorporated as operational requirements evolve.
Weinberger added, “Reliability in production comes down to the details. The gripper head is engineered to perform consistently under real production conditions, with ESD-safe construction ensuring the board is protected at every point of contact. That level of engineering discipline is what makes the difference on a real production floor.”
