ACF (Anisotropic conductive film) or ACF tape is an epoxy / acrylic adhesive system used by electronics industry. This film creates the electrical and mechanical connections from drive electronics to substrates.

The Film contains conductive particles that provides electrical interconnection between pads through the film thickness (z-direction). Yet these particles are spaced far apart thus not electrically conductive in the plane direction (X&Y) of the film.

This interconnection allows low height and fine pitch which enables high density and small area of assembly.

Besides, the conductive particles are made from environmental friendly material (ROHs compliance). It provides good metallic bonding.

Most importantly, ACF interconnect offers cost savings by replacing conventional mechanical connectors or soldering interconnect.
