UKRI-1308 DUNE APA Printed Circuit Boards

Tender description

This PIN is to advise the market of UKRI's current intentions regarding the procurement of Printed Circuit Boards (PCBs). Printed Circuit Boards (PCBs) are needed to construct charge readout anode plane assemblies (APAs) for the Deep Underground Neutrino Experiment based at Sanford Underground Research Facility in South Dakota. Each of these PCBs are required to operate reliably in (Liquid Argon) LAr over many years (>20 years) so Quality Assurance is a critical element to this project. A key requirement for these PCBs are the mechanical tolerances. As described below, board thickness must be maintained to ±5%, and machining of features on the board is required to a high tolerance.
