PWS 25-5E3 - Scope of PCB requirements_Redacted.pdf

3.1.1 PCB FABRICATION REQUIREMENT: The contractor shall produce requested quantities of PCBs in accordance with fabrication requirements and specification documents for board thickness, layer count, surface finish, trace tolerance, and any other pertinent fabrication specifications.

3.1.1.1 The contractor shall fabricate PCBs in accordance with specified IPC-A-600 classification; if IPC Classification is not specified in the provided TDP, the contractor shall fabricate PCBs to IPC Class 3 requirements.

3.1.1.2 The contractor shall provide technical reports, as required, documenting electrical continuity test results, impedance matching test results, and/or results of Quality Control inspections.

3.1.1.3 Unless otherwise specified in the TDP, the contractor has control over panelization strategies, fiducial markings, and excess materials needed to account for production fall out.

3.1.1.4 If the contractor does not have internal PCB Fabrication capabilities, it is acceptable to sub-contract PCB Fabrication to another vendor. Any sub-contractors utilized shall be approved by DMEA in advance of the initiation of PCB fabrication activities. PCB procurement is payable upon contractor evidence of PO placement, evidence of receipt by contractor, and evidence of acceptable PCB performance (circuit continuity).

3.1.1.5 The contractor shall return all excess PCB materials to DMEA after completion of production activities.

3.1.2 COMPONENT PROCUREMENT REQUIREMENT: The contractor shall procure sufficient materials and components, as identified on the BOM, to enable the assembly of requested quantities of PCBAs/CCAs. Any components that will be consigned to the contractor by DMEA will be identified on the BOM.

3.1.2.1 The contractor shall review suitability of Government furnished materials (GFM) and components and request any additional information, materials, and/or components within 5 days of receipt of the GFM

3.1.2.2 The contractor shall only use authorized distributors or Original Equipment Manufacturers (OEMs) to source electronic components. Any alternative sources, like third party distributers or brokers, shall be approved by DMEA prior to components being procured.

3.1.2.3 The contractor shall rapidly execute component orders, to ensure supply chain disruptions can be immediately accounted for and lead times can be minimized. The contractor shall provide evidence of orders being placed and received. For component and material orders that are excessively costly, partial payments and/or early payments can be negotiated prior to award of the order, upon contractor request. Component procurement is payable upon contractor evidence of PO placement and evidence of receipt by contractor; project inventory shall be transferred to Govt if not used.

3.1.2.4 The contractor shall identify suitable alternates to components that are not immediately available, or that have prohibitively long lead times. Any alternate components shall be approved by DMEA subject matter experts (SMEs: the PE or COR as identified on the SOW) prior to procurement of the components.

3.1.2.4.1 Note: DMEA may request some additional spares of critical components be procured, to support rework due to post-production test and validation activities; these spares will be identified in the TDP and BOM, when applicable.

3.1.2.5 Unless quantities of components are deliberately specified or limited in the TDP or BOM, the contractor has control over quantities of sufficient spares needed to accommodate losses possible in their PCB Assembly processes.

Any alternate components shall be approved by DMEA SMEs prior to procurement of the components.

3.1.2.6 The contractor shall return all excess materials and components to DMEA after completion of production activities, unless an agreement exists to maintain to inventory in contractor inventory in anticipation of follow-on orders.

3.1.3 PCB ASSEMBLY REQUIREMENT: The contractor shall assemble requested quantities of PCBAs (also referred to as Circuit Card Assemblies (CCAs)) in accordance with layout specifications and assembly requirement documents for solder selection, component placement, bill of materials, stencil design, and any other pertinent assembly specifications.

3.1.3.1 The contractor shall assemble PCBAs in accordance with specified J-STD-001 and IPC-A-610 classification;

if IPC Classification is not specified in the provided TDP, the contract shall assemble PCBAs to IPC Class 2 requirements.

3.1.3.2 The contractor shall provide technical reports, as required, documenting electrical continuity test results, and/or results of Quality Control inspections performed in accordance with specified IPC-A-610 inspections.

3.1.3.3 Unless otherwise specified in the TDP, the contractor shall use Tin-Lead (Sn-Pb) solder in all applicable assembly process.

3.1.3.3.1 Note: Some components may be fabricated with Lead-free solder. Unless specified in the TDP, these components shall not be reballed. Hybrid soldering processes are acceptable in the attachment of these components.

3.1.3.4 If the contractor does not have PCB Assembly capabilities, it is acceptable to sub-contract PCB Assembly to another vendor. Any sub-contractors identified shall be approved by DMEA in advance of the initiation of fabrication/production activities.

3.1.3.5 The contractor shall return all excess materials utilized in PCB Assembly process to DMEA after completion of production activities, including setup units and units that are not functional after assembly. Setup and failed units shall be clearly marked and segregated from the production units.
