ACF machine ,it 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 machine use the Solder paste as the medium.
It has pulse heat bonding machine and constant temperature bonding machine.
The machine 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 Machine 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.It 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.
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.
