We tried with LG LM170E02 and most of the bondings were sucessful

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
