Used ASM SX4

The ASM SX4 is a highly flexible, modular SMT placement machine from the ASMPT SIPLACE SX series. Designed specifically to handle frequent product changeovers and the placement of complex, odd-form components, it serves as an ideal solution for "high-mix, low-volume" production environments.

Core Performance and Unique Architecture

The machine offers a placement accuracy of ±40 μm @ 3σ (per IPC standards) and a maximum placement speed of 48,000 CPH (for chip components). Its standout technical feature is the Track Feeder System, where feeders are mounted on "sliding carriages" that move along internal tracks. This enables "offline setup and near-instant online replacement" of entire rows of feeders, reducing changeover downtime to an absolute minimum. Furthermore, the system can handle components as tall as 25 mm, as well as complex, non-standard (odd-form) parts, providing a distinct advantage in odd-form assembly.

Positioning and Applications

The SX4 is engineered for flexible manufacturing characterized by high product variety and variable batch sizes. It is particularly well-suited for sectors such as automotive electronics, industrial controls, and medical electronics—fields defined by long product lifecycles and a vast array of model types. In practice, it is often integrated into hybrid production lines alongside high-speed machines from the SIPLACE TX or X series; while the TX/X units handle high-volume placement, the SX4 manages low-volume, high-mix, and odd-form components, thereby maximizing the Overall Equipment Effectiveness (OEE) of the entire line.

Summary

The SX4 is a flexible SMT placement machine whose core competitive strengths lie in its "zero-downtime changeover" capability and its proficiency in handling odd-form components. Rather than prioritizing raw speed, it addresses the primary pain point of high-mix production through a revolutionary feeder architecture, making it a vital component for high-end, flexible SMT production lines.
