This document covers requirements and test methods for anisotropically conductive adhesive films used to bond and electrically connect components and for their long-term properties as a part of the printed wiring board assembly. Applications include the following: flexible PWB-to-glass, flexible PWB-to-rigid PWB, flip chip-to-glass, flip chip-toflexible PWB, flip chip-to-rigid PWB, and fine pitch SMD. The adhesive film may be supplied pre-attached to a flexible circuit or other product.

Purpose This standard defines anisotropically conductive adhesive films (also known as Z-axis films, ZAF) through specification of test methods and inspection criteria.
