Bonding Machines

Bonding Machines

Bonding Machines, is the widely used machine in the LCD/LED/OLED, LCM/open cell/panel/screen/display produce factories and repairing service shops all over the world.

The Bonding Machines is based on the recent innovations as well as planned to repair the arrangements of LCD, LED,OLED, TV/television, Laptop, Pad, Cell phone, Watch, Touch Panel, Ad Player, and all the flat and edge screens.

The Bonding Machines may consist of HD Digital Microscope, and also has a Digital Pressure Gauge, and vacuum generator which may help to hold the panel during the bonding process. The bonding press head may press the IC/FPC/COF onto the Glass/PCB/FPC using ACF conductive adhesive as medium, by a certain temperature, pressure and time. also some bonding machine use the Solder paste as the medium.

Bonding machine

The machine use the ACF tape as the medium ,so it also named ACF bonding machines.

According to different LCD/LED/OLED and different screens, there are many ACF tapes models.  ACF tape is the important medium of the bonding process.bonding machines

What is ACF?

ACF Tape/ACF Film  & Applications

ACF Tape is normally made up of two main components, namely Adhesive & conductive particles.


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),chip-on-film(COF), flex-on-board(FOB),flex-on-flex(FOF) 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 tape

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 special conductive particle is made from environmental friendly material (ROHs compliance). It provides good metalic bonding.

What is ACF Bonding?

During ACF bonding, a combination of heat & pressure is applied on to chip (FPC/IC) for an appropriate time.

Conductive 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.

Bonding Machines Applications

ACF has for many years, been used in glass display applications. Recently, it is also becoming widely used in TAB,COG,FOG,FOB,FOF,COF,COB areas.

OLED Bonding Machines


What is OLED?

 OLED namely Organic Light-Emitting Diodes (OLED), also known as Organic laser Display (Organic Electroluminescent Display, OELD).It has illuminated, simple structure, ultra-thin, fast response, wide Angle, low power consumption, and can realize the flexible display features, known as the “dream” monitor, OLED display technology and the traditional LCD display in a different way, no need backlight, with very thin organic materials coating and glass substrates, when a current through the organic material will glow.

OLED including passive-matrix organic light-emitting diode (PMOLED) and active-matrix organic light-emitting diode (AMOLED), is a technology that organic materials emit light under the action of electronic field. Succeeding CRT and LCD, OLED is a new-generation flat panel display technology and extolled as “dream like display technology”.

  • Vivid color

The NTSC color gamut of OLED can break through 100%, much higher than that of LCD.

  • Fast response

The response time of OLED is normally in microseconds, only 1/1000 of that of LCD, which is in milliseconds.

  • High contrast ratio

The contrast ratio of OLED is at least 100000:1, which is much higher than that of LCD, which is at the level of 1000:1

  • Flexible panel for creative thinking

OLED is suitable for flexible display due to its ultra-thin, large visual angle and good mechanical properties.
