Metal-clad dielectric sheeting |
摘要 |
Metal-clad dielectric sheeting useful in the manufacture of printed circuitry comprising an electrically conductive metallic layer adhered to a nonwoven web that comprises a unique fiber blend compacted and held together by a polymeric binder material. The fiber blend includes heat-resistant fibers (preferably aromatic polyamide fibers) and high-tensile-strength fibers that absorb little moisture (preferably polyester fibers); and the amount of fibers that absorb moisture is held to a low amount.
