Used MDC 490B-6NI #293590452 for sale

MDC 490B-6NI is an advanced prober designed for use in semiconductor wafer testing applications. It is a fully-featured automated prober featuring built-in electronics, precision probes, and wafer handling capabilities. 490B-6NI has a unique modular design, allowing for rapid reconfiguration for different applications. The main components of the equipment include a prober arm, a probe positioning system, and a hand-held joystick for manual operation. The prober arm is designed to support heavy wafers up to 8" in diameter. The arm is designed to be mounted on a large 2-axis stages and provides 360° free rotation. The positioning unit is composed of a motorized X-Y table and X-Z stage, and it supports 0.5 micron of resolution. The prober arm is equipped with an array of precision probes, including a wafer mapping machine, multiple probe benders, and precision alignment needles. The probes are designed to promote optimal contact with the surface of the wafer. MDC 490B-6NI offers a range of features for automated operation. It is equipped with a programmable controller, a control PC and scanner, and bar code readers for batch handling. It also includes an RJ45 port for connection to remote control software. In addition, the prober has programmable test sequencing, memory and test pattern comparison, adjustable proximity, and automatic deviation and retest cycles. 490B-6NI is engineered and built for performance in highly-demanding, demanding wafer testing environments. Its robust design, precision probes, and range of features make it an ideal automated prober for the most demanding wafer testing applications.
