80 The PCB Magazine • April 2017 Insights into the structure of the proposed process methodologies, how the existing struc- tures will be leveraged during the transition toward full implementation, what a potential ideal end-state might look like, and status for the effort are provided. Introduction To strengthen the U.S. PrCB industrial base and DoD supply chain for national security systems, the PrCB EA is developing and imple- menting a PrCB Trust Accreditation process for PrCB manufacturers and service providers. The motivation for this initiative comes from the National Research Council's 2008 Report to Congress [8] and is further based on DoDI 5200.44 [3] . In addition to establishing a trusted DoD electronics supply chain, the initiative aims to provide cost savings to both DoD and industry through a standard trust accreditation process that leverages compliance with relevant commercial standards, eliminates redundant audit functions, and increases competition for DoD work. As technology progresses and DoD systems become further reliant on electronics, the trust accreditation process will be critical for securing the DoD PrCB industrial base going forward, es- pecially in the context of cloud computing and the internet of things where information securi- ty and system security have become even more entangled. In the scope of the above rational, trusted status is assigned to a supplier of PrCB related products and/or services when that sup- plier has consistently demonstrated the ability to meet specified requirements for quality, sup- ply chain management, CoC, and security. PrCBs and assemblies provide the mechani- cal infrastructure and electrical interconnects that serve as the foundation of all electronic systems. Key PPP elements are quality, availabil- ity, security, and CoC—all of which directly im- pact program schedules, life-cycle cost, perfor- mance, and reliability. DoDI 5000.02 and DoDI 5200.39 establish the requirements for PPPs to manage risks to advanced technology and mis- sion-critical system functionality throughout the acquisition lifecycle [1-2] . The Defense Acquisition Guidebook (DAG) chapter 13 section 13.2 states the purpose of the PPP is "…to ensure that programs adequately protect their technology, components, and in- formation throughout all phases of the acqui- sition process including design, development, delivery and sustainment" [9] . DMEA developed the Trusted Foundry Program to satisfy the requirement of DoDI 5200.44 policy for integrated circuits and field- programmable gate arrays (FPGA) which re- quires programs to "employ protections that manage risk in the supply chain for compo- nents or subcomponent products and services (e.g., integrated circuits, FPGA, PrCBs) when they are identifiable (to the supplier) as having a DoD end-use" [3] . To satisfy the same policy requirement, the PrCB EA has developed a PrCB Trust Accreditation process for the design, man- ufacture, and assembly of PrCBs. The purpose of this accreditation is to support Program Offices in the development of their PPP where PrCBs have been identified as a Critical Technology. The accreditation may also be used in any circumstance where the reliability of PrCB sys- tem components has significant impact on pro- gram risk. To establish a common basis of terms, the DoD Directive 5101.18E for the PrCB EA has de- fined the following terms: Interconnect Technology: Technology asso- ciated with all physical connections that pro- vide mechanical, chemical, electrical, optical, sonic, or thermal linkages between a pairing of individual components, integrated circuits, electronic subassemblies, or the application en- vironment.
