概要（Overview）

A pick-and-place hander that handles eight DUTS in parallel for a total throughput of up to 8,000 devices per hour. The M4871 handler features a variety of capabilities for improving test yields and reducing cycle times. An advanced visual-alignment function enables positioning accuracy of below 0.3 mm ball/pad pitch for handling fine-pitch semiconductors and devices with both top- and bottom-side contacts. This precise alignment capability also helps to speed up set-up and calibration times for greater test-cell productivity.
