Used CASCADE MICROTECH / ALESSI REL 4800 #293808876 for sale

CASCADE MICROTECH / ALESSI REL 4800 is a fully automated manual wafer prober specifically designed for testing high-density semiconductor devices. It features an electro-mechanical wafer probe carriage with a range of 0.3 to 10.2 inches. The prober can cover devices with different size of contactor and test elements, and also die sizes up to 0.90 inches in both vertical and horizontal directions. It supports die rotation in both directions and uses a flexible particle-free contactor with multiple contact configurations. The remote prober head allows for the testing of wafers placed in a fixed position. The large wafer capacity of up to 10 inches in diameter makes it suitable for a wide range of applications. The prober also offers high-speed probing and utilizes a mechanical and optical approach for detecting open and shorted contacts. The mechanical unit enables a smooth and complete data acquisition process, while the optical feature provides users with an improved repeatability and accuracy. The prober is also equipped with a multi-level bias menu which allows users to select the best sampling parameters according to their needs. The wide range of test contacts supported by the prober includes both active and passive devices. In addition, the prober offers an integrated tracking system to keep track of wafer IDs,die IDs, and contact IDs. This feature ensures that the same device is tested multiple times accurately. The prober has a spacious work area which allows for the easy handling and positioning of the wafers. An integrated ERS controller facilitates the interaction of the prober with external devices. The internal transport pathways also enable a quick and efficient transport of wafers between different stages. Overall, ALESSI REL 4800 is an advanced machine which is capable of testing high-density semiconductor devices with fast and accurate results. Its multiple contactor options, integrated bias and tracking menus, and support for multiple die sizes make it suitable for a wide range of applications.
