Covers the requirement for high-temperature, fully-cured, metal-clad, thin laminated plastic sheets, to be used primarily for high-temperature multilayered and thin printed boards for electrical and electronic circuits. This specification applies to sheets when the base laminate does not exceed 0.79mm (0.031 inch) in nominal thickness. Recognizes that printed boards are subject to classifications by intended end-item usage. Thus, where applicable, for ordering purposes the multilayer printed board laminate material is specified.
