Attachment 1_PVD Shield and Chamber Parts_071426.xlsx

This is a detailed parts and materials specification sheet for Physical Vapor Deposition (PVD) chamber components and shields required for the Bureau of Engraving and Printing's (BEP) ablative laser cleaning services solicitation (2031ZA26Q00088). The spreadsheet itemizes 39 distinct shield and chamber parts with their respective quantities, surface areas, and material specifications, all constructed from AISI 304 stainless steel or stainless steel variants.

The components are organized into several functional categories: chamber shields (upper left, upper right, viewport side shields, lower chamber, and cryogenic trap shields), cathode shields and related components (side cathode shields, top and bottom shields, and upper/lower cathode shields), shutter and access panels, heater plates and supporting structures, anodic plates, and removable chamber covers. The removable covers total 205,536 cm² (221.24 sq ft), while the main chamber components (doors, walls, floors, and ceilings) total 57,176 cm² (61.54 sq ft), for a combined total surface area of 262,712 cm² (282.78 sq ft). This specification document supports BEP's requirement to implement controlled, non-contact laser cleaning processes that preserve the integrity of IPC 1100 PVD machine components and maintain peak operational specifications for chrome coating production on intaglio plates. Amendment 0002, posted July 14, 2026, updated the attachment with revised square footage totals.
