Actual COF Bonding


TAB bonding Operation May 14 2012

Operation Report May 14 2012



We removed a Single TAB (COF) of LG LM170E02. We cleaned remaining ACF from the COF and attached a new ACF. We proceed TAB/IC bonding and verified the Lamination.



1.       First Trial


[Picture 1. Relevant parameters]


The pressing location was wrong so we adjusted the LCM aligment postion to 16.95mm(LEFT) and 16.45mm (RIGHT) and the bonding was successful on the second trial. The temperature was also too low and we increased the temperature to 235 degrees celcius.
