MIL-PRF-55110 Printed Wiring Board, Rigid, General Specification ForThis specification establishes the performance and qualification requirements for rigid single??sided, double??sided, and multilayered printed wiring boards with or without plated through holes \(see 6.1\). Verification is accomplished through the use of one of two methods of product assurance \(QPL or QPL/QML\). Detail requirements, specific characteristics, and other provisions which are sensitive to the particular intended use are specified in the applicable master drawing.
