In one embodiment, the present invention relates to a flexible laminate,ncomprising a first flexible polymeric film; a copper layer having a microcrackingnprevention layer on at least one side the microcracking prevention layer sufficient tonprevent microcracks in a copper layer having a thickness of up to about 18 µmnduring at least 50,000,000 bending cycles and/or a copper layer having a thicknessnof up to about 35 µm during at least 20,000,000 bending cycles of the flexiblenlaminate; and a second flexible polymeric film. |
