Gives requirements for properties of thin polyimide woven glass fabric copper-clad laminated sheet of defined flammability to be used in the fabrication of multilayer printed boards. Covers laminated sheets that have thicknesses (of the base laminate, excluding the copper foil) not in excess of 0,8 mm (0,031 in). The materials, although primarily meant for multilayer boards, may be used for single-sided or double-sided printed boards. Coverage includes materials and construction, internal marking, electrical properties and acceptance testing.
