Used ITC PB500A #141467 for sale

ITC PB500A prober is a powerful, microprocessor-controlled, fully automated wafer prober. It is designed to handle wafers up to 8 inches in diameter and up to 0.7 mm thick. The device is comprised of a base unit that houses a programmable controller and a fully motorized prober module, with the capacity to hold up to four standard wafer load ports. The load ports have a simple loading process, allowing for quick sample exchange. The equipment also includes a manual load port for special applications. PB500A performs automated sample probing at various stages of wafer fabrication and testing, enabling accurate and rapid positioning and measuring of wafer circuits. The precision of this prober is ensured by the use of high-precision lead screw drive motors, providing a very low backlash error of 0.8 microns. The scanning system is further enhanced by the use of optical position measurement systems, and a self-contained laser interferometer. The device offers automatic probe docking, thereby allowing for quick probing adjustments, and various types of probing heads can be selected, including both contact and non-contact probes, depending on the application. Additional features of ITC PB500A include an integrated wafer chucking unit for secure wafer placement during probing, and a unique air bearing probe. The airbearing machine is designed to keep the probe in contact with the wafer at all times, even during the probing process, and to reduce the chance of damaging the circuit. The prober also has an Ethernet connection and offers remote control from a separate PC, enabling efficient maintenance and control of multiple systems. PB500A offers a comprehensive library of tests, including pre-scanning, probing, signal integrity, signal characterization, and electrical fault testing. In short, ITC PB500A is a powerful and accurate prober with a high level of performance and functionality. Its automated slide tool and precision probe head result in reliable and repeatable sample probing of circuits. Additionally, the prober's Ethernet connection and remote control features make it particularly suitable for use in large-scale applications and high-volume production environments.
