UL 796 10th Edition, “Standard for Printed-Wiring Boards,” has just been amended by a new change revision. The change notice includes the new designation as an ANSI approved standard and is now available from Document Center Inc. Should you purchase the entire document instead, the revision changes will be interfiled into the text for you.
UL 796 applies to rigid printed-wiring boards and flexible printed-wiring board for use as components in devices or appliances. Compliance with the requirements of the standard does not indicate that the product is acceptable for use as a component of an end product without further investigation.
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.
The 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.
UL 796 does 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. These are covered by the Standard for Flexible Materials Interconnect Constructions, UL 796F.
