Used JEL 9808005 #9396478 for sale

JEL 9808005 wafer handler is an integral component of a wafer processing line. The device is designed to enable precise and reliable handling of wafers up to 5" in diameter. The main features of the handler are the high throughput conveyors, the wafer transport equipment, and the wafer centering. The conveyors are made from low-friction polymeric material, allowing for high throughputs up to 14 wafers per hour with minimal particle or contamination intake. The conveyors use multiple small wheels with adjustable tensioners to ensure continuity of movement without the need for additional force. A series of sensors and lifters are also included to provide an accurate measurement of wafer thickness and diameter. The wafer transport system conveys wafers from the conveyors to the centering and aligning mechanisms. This is enabled by a unique two-part guiding unit with an indexed slide rail in the lower part and a precision motorized positioning machine on the upper part. The indexing allows for high positioning accuracy while the motorized tool permits fine tuning of the alignment. The wafer centering and aligning mechanisms are designed to perform a variety of tasks. First, the centering mechanism uses a number of spring-loaded pins to ensure all wafers are centered before transport. Secondly, the wafer alignment mechanism uses precision rollers that automatically adjust the vertical and horizontal alignment of incoming wafers. Additionally, a safety switch is included that prevents the automatic transfer of wafers that are not in the correct alignment. Finally, 9808005 wafer handler is also equipped with in-line monitoring capabilities. A vision asset is integrated with the software to detect possible errors with the transport, alignment, and centering of the wafers. In addition, the wafer handler is designed for minimal maintenance and cleaning, as well as easy integration into larger systems. In summary, JEL 9808005 wafer handler is a reliable and high-precision wafer handler designed to ensure effective wafer processing for a variety of applications. The device's unique features enable precise handling of wafers with a high throughput capacity, along with monitoring sensor and vision systems for secure conveyance and real-time detection of errors.
