As the drivers for LCD/FPD displays are not readily available on the market, nondestructive disassembly of the TCP-mounted drivers is paramount to level 3 repair. TCP attachment is currently done with thermoset ACAS based on epoxies. These adhesives are very tough. For efficient removal of TCP circuits, especially if the TCPs shall be reused, the adhesive must be weakened before removal of the TCP. An additional difficulty is that the adhesives used for attaching the copper to the PI substrate of the TCP in the production process are quite similar to the ACAS used for their thermal resistance. Therefore, action for weakening the ACA must be as selective as possible. Our Proprietary equipment allows us to securely disassemble TCPs from scrap LCD/FPD panels.
