Commonly installed in Ultratech 4700, 6700, Titan, and Saturn wafer steppers where it supports precise focus measurement and stage positioning during wafer exposure. Semiconductor equipment technicians and field service engineers use this board for replacement of failed focus control PCBs, preventive maintenance, and restoration of accurate lithography performance. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"676\" data-end=\"693\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"694\" data-end=\"1279\"\u003eThe Ultratech Stepper 03-20-01955 5 Axis Focus A\/D Board is commonly used in semiconductor wafer fabrication, MEMS manufacturing, advanced packaging, and research facilities operating Ultratech photolithography systems. The board converts and processes analog signals from the five-axis focus subsystem, enabling real-time autofocus control and precise wafer stage positioning for high-resolution exposure. Compatibility should be verified using the original part number, revision level, and applicable Ultratech stepper model before installation. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1281\" data-end=\"1310\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1311\" data-end=\"1921\"\u003e• Brand: Ultratech Stepper\u003cbr data-start=\"1337\" data-end=\"1340\"\u003e• Part Number: 03-20-01955\u003cbr data-start=\"1366\" data-end=\"1369\"\u003e• Product Type: 5 Axis Focus A\/D Board \/ Printed Circuit Board (PCB)\u003cbr data-start=\"1437\" data-end=\"1440\"\u003e• Function: Analog-to-digital focus signal processing\u003cbr data-start=\"1493\" data-end=\"1496\"\u003e• System: 5-Axis Autofocus Control\u003cbr data-start=\"1530\" data-end=\"1533\"\u003e• Compatible Equipment: Ultratech 4700, 6700, Titan, and Saturn Wafer Stepper Systems\u003cbr data-start=\"1618\" data-end=\"1621\"\u003e• Board Type: Industrial Motion Control PCB\u003cbr data-start=\"1664\" data-end=\"1667\"\u003e• Mounting: OEM replacement board\u003cbr data-start=\"1700\" data-end=\"1703\"\u003e• Installation: Direct OEM replacement\u003cbr data-start=\"1741\" data-end=\"1744\"\u003e• Application: Semiconductor photolithography and autofocus systems\u003cbr data-start=\"1811\" data-end=\"1814\"\u003e• Designed for continuous-duty semiconductor manufacturing operation. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"1923\" data-end=\"1947\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1949\" data-end=\"2048\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Ultratech Stepper 03-20-01961\u003cbr data-start=\"1980\" data-end=\"1983\"\u003e• Ultratech Stepper 03-20-01967\u003cbr data-start=\"2014\" data-end=\"2017\"\u003e• Ultratech Stepper 03-20-01989\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Ultratech","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51714362671406,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6da24e9a-fa41-4da0-ac15-6786d1fac8ea.jpg?v=1770424122","url":"https:\/\/plgautomation.com\/products\/ultratech-stepper-03-20-01955-5-axis-focus-a-d-board-printed-circuit-board","provider":"PLG Automation ","version":"1.0","type":"link"}
