This government file outlines the stringent qualification requirements for manufacturers bidding on the DUNE FD-VD FEMB IO-1865-1K PCB fabrication project. The core requirement is demonstrated experience in producing complex cryogenic electronics PCBs capable of operating at 77 K. Bidders must have a minimum of 10 years' experience in complex PCB fabrication and provide references for at least three successfully completed jobs with comparable complexity. These references must detail specific parameters such as PCB size, layer stack-up, impedance control, minimal via size, drill count, unique QR codes, IPC-6012 class II compliance, and evidence of cryogenic use (< 120 K). Failure to provide this comprehensive information will result in disqualification, ensuring that only highly qualified manufacturers capable of meeting the DUNE project's demanding schedule and technical specifications are considered.

This document outlines the manufacturing requirements for SRS boards. Key provisions include the identification of authorized technical representatives, who must approve any changes to the lead time. The vendor is responsible for shipping, providing labor, and all necessary parts for the SRS boards. All parts must be new. The vendor must fabricate the SRS boards within the specified lead time unless a longer turnaround is approved by the technical representative. After-hours or weekend calls are not expected or authorized under this statement of work.
