Commonly installed in Ultratech 4700, 6700, Titan, and Saturn wafer steppers where it serves as a central interface between the VME architecture and the machine's motion control, vision, and I\/O subsystems. Semiconductor equipment technicians and field service engineers use this board for replacement of failed control PCBs, preventive maintenance, and restoration of reliable lithography system operation. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"707\" data-end=\"724\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"725\" data-end=\"1332\"\u003eThe Ultratech Stepper 03-20-00870 VME Combo Board is commonly used in semiconductor wafer fabrication, MEMS manufacturing, advanced packaging, and research facilities operating Ultratech photolithography equipment. The board manages communication between multiple system modules through the VME bus architecture, supporting coordinated operation of wafer handling, stage motion, reticle alignment, and machine control functions. Compatibility should be verified using the original part number, board revision, 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=\"1334\" data-end=\"1363\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1364\" data-end=\"1990\"\u003e• Brand: Ultratech Stepper\u003cbr data-start=\"1390\" data-end=\"1393\"\u003e• Part Number: 03-20-00870\u003cbr data-start=\"1419\" data-end=\"1422\"\u003e• Product Type: VME Combo Board \/ Printed Circuit Board (PCB)\u003cbr data-start=\"1483\" data-end=\"1486\"\u003e• Bus Architecture: VME\u003cbr data-start=\"1509\" data-end=\"1512\"\u003e• Function: System communication and machine control interface\u003cbr data-start=\"1574\" data-end=\"1577\"\u003e• Compatible Equipment: Ultratech 4700, 6700, Titan, and Saturn Wafer Stepper Systems\u003cbr data-start=\"1662\" data-end=\"1665\"\u003e• Board Revisions: Rev.
