Abstract
A flexible metal clad laminate includes a metal foil, and a multilayered polyimide film including a first polyimide layer having a glass transition temperature of 300° C. or less and disposed on the metal foil, a second polyimide layer disposed on the first polyimide layer and a third polyimide layer disposed on the second polyimide layer. According to the flexible metal clad laminate of the present invention, appearance defects such as blistering generated during curing process in a continuous curing machine using an infrared heat source may be solved, interlayer delamination may be prevented due to a good adhesion strength with a metal layer, and an ACF bonding strength and a dimensional stability may be good. The flexible metal clad laminate may be useful for the manufacturing of a flexible printed circuit boards.
