Abstract
A flexible printed circuit board base film for flexible printed circuit boards includes a sheet of flexible polymer matrix and a number of carbon nanotube bundles embedded in the polymer matrix. Each of the nanotubes bundles are spaced apart from each other. The flexible polymer matrix includes a first surface and a second surface. Due to the high thermal conductivity of carbon nanotubes, heat can be efficiently conducted from the first surface to the second surface of the flexible printed circuit board base film. The present invention also provides a flexible laminate made from the flexible printed circuit board base film and a flexible printed circuit boards made from the flexible laminate.
