What are the types of ACF/COF/TAB faults?
There is a picture below shows the ACF/COF/TAB fault in a TFT LCD Panel of a LED TV.
There are few COFs/TABs to connect TFT LCD Panel glass and PCB boards, which are called as X COFs and Y COFs, sometimes vertical or horizontal lines (bands) appeared on the TFT LCD Panel of LED TV screen. One of the reasons is the COF/TAB burned or loose bonding. In order to solve this problem, if the COF just have loose bonding (not burned), use bonding machine to re-bond the same COF; if COF is burned or physically disconnecting (like chip broken), use bonding machine to replace the same with a new COF of same number or replacement number.
What’s the payment and delivery time?
- Payment terms: EXW/FOB/CIF, by T/T, 100% deposit in advance (Recommend)
- Delivery time: about 1 to 3 weeks
How about the warranty?
- Usually, we provide 1-year standard warranty against manufacturing defects and whole life technical support.
