Used ELECTROGLAS / EG 4090u #293606463 for sale

ELECTROGLAS / EG 4090u prober is a historical, semi-automated wafer prober widely used in the semiconductor manufacturing industry. EG 4090u is mostly used in failure analysis and characterization probing applications in laboratories around the world. The equipment is mainly composed of a vertical arm, which moves a probe card over the individual or multiple test sites on the wafer. The vertical arm is manufactured from either aluminum or stainless steel, depending on the customer's specific requirements. It has a large X-Y motion range and can provide an evenness of repeatability and precision with its smooth movement. The vertical arm is attached to a motion control/signal conditioning sub-system enabling fast response time and reliable probing during testing. It is also capable of controlling up to four independent axes - X, Y, Z, U. The prober also has a vision camera unit that allows for accurate alignment of the probe card over the test sites on the wafer. This vision machine is maintained and calibrated regularly through its intuitive software interface, making sure that the probe card is always in alignment over the test sites. The probe cards can either be programmable or fixed options. The 4000u offers a unique programmable feature that allows users to create probe cards with a combination of active and passive probes, based on their specific application requirements. The active probes enable advanced testing capability due to their higher frequency operation and fast response time, while the passive probes are more suitable for static probing applications. To achieve a reliable electrical contact between the probe card and the wafer under test ELECTROGLAS 4090 U is fitted with a vacuum tool, which is designed to hold the probe card in place. The prober also comes with a pneumatic asset for the probing, cushioning and contactor parts, and a buffering model for delivery and take-away of wafers. For safety reasons, ELECTROGLAS / EG 4090 U is equipped with a dual-door housing designed to protect all operating components from any external interference or damage. All doors must be closed for the equipment to commence operation with the toggles on both doors monitored by an electronic interlock system. 4090 U has additional optically isolated I/O features allowing external testing accessories such as test boards and test seats to be connected, furthering its applications. 4090u prober is one of the few semi-automated systems offering maximum flexibility and reliability. With its precise X-Y motions, vision camera alignment unit and active/passive probes it is suitable for a wide range of failure analysis and characterization probing applications.
