Product Application

ACF Tape, ACF Film
ACF Tape is normally made up of two main components, namely Adhesive & conductive particles.
Adhesives
The adhesive composition is dependent on the materials being assembled. This means an ACF designed for use in a flex-on-glass (FOG) assembly is usually not suitable for use in a chip-on-glass (COG), FOB, or any other configurations. It is specific to the application for which it is designed for.

ACF Conductive Particles

Conductive particles are used to conduct electricity from one side of the bond to the other. Depending on the application, conductive particles range from 3.5μm to 30μm in size, and can be made from Nickel-gold plated polymer spheres, gold plated nickel particles, or lead-free solder materials. Particles may be individually coated with a outer polymer to insulate them from other uncrushed particles, but which will crack open and allow electrical conduction if the particle is trapped and crushed between two pads during assembly.


ACF Anisotropic Conductive Film

ACF (Anisotropic conductive film) or ACF tape is an epoxy adhesive system used by electronics industry to make electrical and mechanical connections from drive electronics to substrates.
ACF are filled with conductive particles which provides electrical interconnection between pads through the film thickness (z-direction).
The conductive particles are distributed far apart thus not electrically conductive in the plane direction (X&Y) of the film.
ACF interconnect offers cost savings by substituting conventional mechanical connectors or soldering interconnect.
ACF interconnect allows low height and fine pitch which enables high density and miniaturizing of assembly.

ACF Bonding
During ACF bonding, a combination of heat & pressure is applied on to chip (FPC/IC) for an appropriate time.
Conductives particles (each 3~30um) are compressed between IC and substrate (glass / PCB) while insulating materials pushed away.
This allows the compressed Ni-Au layer on the particles to conduct electricity between the IC and the substrates (z-axis).
The insulated particles are distributed with a minimum chance of electrical shorting in the x-axis and y-axis.
As the epoxy cures and conductive particles are trapped into permanent compressed form.
The compressed particles, by its elastic nature, are constantly pushing outwards to maintain good electrical conductivity under different environmental conditions.
ACF has for many years, been used in glass display applications. Recently, it is also becoming widely used in COF and COB areas.
