Committee on Manufacturing Trends in Printed Circuit Technology, National Research Council9780309100342, 0309100348

Over the past two decades, the Department of Defense has been moving toward commercial-military integration for manufacturing, while at the same time, the printed circuit board industry has been moving steadily offshore. Today, many in DoD, the U.S. Congress, and the federal government lack a clear understanding of the importance of high-quality, trustworthy printed circuit boards (PrCBs) for properly functioning weapons and other defense systems and components. To help develop this understanding, DOD requested the NRC to identify and assess the key issues affecting PrCBs for military use. This report presents a discussion of how to ensure DOD’s access to reliable printed circuits; an assessment of its vulnerability to the global printed circuit supply chain; and suggestions about ways to secure the design and manufacture of printed circuits. In addition, this report offers recommendations to help DoD preserve existing systems’ capabilities, improve the military’s access to currently available PrCBs, and ensure access to future PrCB technology. The recommendations reflect the need to achieve these goals at reasonable cost and in concert with evolving environmental regulations.
