Bonding 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 use the Solder paste as the medium.
It has pulse heat and constant temperature machines.
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 pressing 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.
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.

Shenzhen Olian-Bonding Machines Factory
Shenzhen Olian, specializing in the production of pulse hot press, constant temperature hot press, FPC/FOG/FOB/FOF bonding machine, ACF attaching machines, IC/CHIP/COG/COF pre-bonding equipments, COG/COF main-bonding equipments, COF cutting machines, LCD TV repair equipment OLB/TAB/PCB/TCP, microscope, plasma cleaning machines, COF punching machines, LCD screen production and maintenance supplies machines parts and other accessoreis one-stop services.
The bonding machine is a method of heating two parts of the pre-good flux tin-plated (ACF conductive paste) enough to melt and flow the solder (ACF conductive paste), after curing, in parts and solder (ACF conductive paste) ) form a permanent electrical and mechanical connection device. Should be different products, the heating rate can be selected. The hot head ensures an average temperature, fast temperature rise and long service life. The indenter is specially designed with a horizontal adjustment to ensure that the components are pressure averaged. The temperature is numerically controlled and clear and precise. A digital pressure gauge is available to preset the pressure range.
The hot press machine is also known as the bonding machine . According to different media of hot pressing, it can be divided into soldering, ACF (asymmetrical conductive tape), ACP (anisotropic conductive glue), and TBF (hot melt adhesive film). Suitable for FPC (flexible circuit board), HSC (zebra paper), TAB and LCD and PCB connection. Since the Pitch of PCB or FPC in consumer electronics tends to be small, the conventional soldering process has been difficult to meet the requirements of extremely fine hot pressing. The ACF process has been gradually applied by mobile phone designers.
1.Pulse hot press uses pulse heating technology, temperature control is accurate, temperature sampling frequency is 0.1s. Constant temperature heating method, the temperature is constant after the temperature is raised to the preset temperature. 2. Diversified working modes such as single working platform, rotating working platform, and left and right mobile platforms. 3, multi-stage heating control. 4. Real-time temperature curve display. 5, silicone with indexing mechanism. 6, CCD vision system, providing accurate alignment. 7, large-capacity programs are pre-stored. 8, touch operation interface, program password protection.
Bonding machines classification:
Constant temperature , pulse hot press , double station machines, desktop machines, vertical bonding machines, etc.
