UL 796 BULLETIN

Abstract

These requirements apply to rigid printed-wiring boards and flexible printed-wiring board for use as components in devices or appliances. Compliance with these requirements does not indicate that the product is acceptable for use as a component of an end product without further investigation. <br>The flexible printed-wiring boards covered by these requirements consist of conductors affixed to insulating base film, with or without a cover-lay film, with midboard connections. <br>These requirements do not cover flexible printed-wiring boards of laminated-film construction in which the conductors are parallel to each other and are completely covered by the base film with only point-to-point end connections. <br>These requirements do not apply to flexible, flex-to-install, rigid, and multilayer rigid flex composite interconnect constructions with and without stiffener and adhesive materials as flexible materials interconnect constructions (FMIC's) for use as components in devices or appliances &#8211; that are covered by the Standard for Flexible Materials Interconnect Constructions, UL 796F.
