FLEXIBLE PRINTED CIRCUIT BOARD AND METHOD THEREOF, BACKLIGHT UNIT HAVING FLEXIBLE PRINTED CIRCUIT BOARD

摘要

A flexible PCB(Printed Circuit Board), a method for manufacturing the same, and a backlight unit having the same are provided to simplify a process by replacing a temporal bonding process and a thermocompression bonding process of a coverlay layer with an ink coating process. A flexible PCB(200a) includes a both-sided copper clad laminate(20) and ink layers(100). The both-sided copper clad laminate is composed of an insulation layer(20a), an adhesive(20b), and a copper foil layer(20c) or the insulation layer and the copper foil layer. The ink layers are respectively formed on upper and lower surfaces of the copper foil layer of the both-sided copper clad laminate to function as a coverlay layer of a conventional flexible PCB.
