From the Hill: Have You Hugged Your Technical Review Board Lately?

The Technical Review Board’s (TRB's) duties and responsibilities are the glue that connects the dots between the site, the Defense Logistics Agency (DLA), and the associated military revenue stream. Understanding these duties will help with resource allocation, general support, site priorities, and, most importantly, yearly re-certification to MIL-PRF-31032. Mike Hill explains the function of the TRB as it pertains to MIL-PRF-31032 (military requirements for printed wiring board fabrication).
