(3) COF Bonding machine, COF Bonder, or TAB/IC Bonder/ Driver IC Bonder
(4) ACF Tacker or ACF Bonder
ACF Tacker or ACF bonder is to attach ACF on to 1 side of COF (TAB/IC or Driver IC)
ACF tacker cost around US$2,000 or less.
(5) COF Bonder
COF bonding machine is to attach COF on the glass and PCBA. The lead on the COF is around 20um (0.00002mm) di
distance each other and this machine demands a high accuracy. Since most of the repairing companies are recycling COF and the surface of COF shall be expanded or shrinked on the bonding operation.
32inch bonding machine would cost around US$30,000, but 42inch bonding machine will be sold around US$40,000. 68inch machine ranges around US$50,000.
