摘要: There are provided a process for producing a two-layered tape for TAB, which comprises forming desired holes in a semi-cured polyamic acid film formed on a release film or in a semi-cured polyamic acid film subjected to stretching of 10% or more, then pressure-bonding the resulting film or film laminate to a conductor foil or a conductor foil on which a semi-cured light-transmittable polyamic acid film is formed, so that the polyamic acid film and the conductor foil contact with each other or the two polyamic acid films contact with each other, conducting imidization, and thereafter forming a desired pattern in the conductor foil; a process for producing a stretched polyamic acid film by subjecting a polyamic acid film to stretching of 10% or more; and a process for producing a flexible base board for printed circuit or a flexible printed circuit board with a cover layer, both using said stretched polyamic acid film.
