Abstract:
A laminated polyester film, with excellent adhesive properties for use in a laminating material, is a film in which a resin layer including a polyester resin and a oxazoline-based cross-linking agent is laminated on at least one side surface of polyester film, diethylene glycol accounts for 40 mole% or more of all diol components constituting the polyester resin and the mass ratio of the polyester resin to the oxazoline-based cross-linking agent resin layer is within a range of 20/80 to 80/20. The film may form part of a flame-retardant polyester film in which a polyimide-including layer is laminated on both sides of the laminated polyester film. The flame-retardant polyester film may be used in a copper-clad laminated plate, which, in turn, may be used in a circuit substrate.

Abstract:
A printed circuit board is made from at least one non-woven sheet or web layer comprising at least 50 % by weight acrylic fibers, with any balance substantially electrically non-conductive fibers, filler, and binder. The sheet or web is preferably made by the foam process, and may contain 60-80 % straight polyacrylonitrile fibers and 40-20 % fibrillated (pulp) ones. The web or sheet is preferably compressed by thermal calendering so that it has a density of about 0.1-1 grams per cubic centimeter; and the web or sheet may have a basis weight of between about 20-120 grams per square meter. The web or sheet may also have a 1-40 % of substantially electrically non-conductive organic or inorganic binder, or may be substantially binder free. A printed circuit board made using the layers of these non-woven webs or sheets is otherwise conventional, including a pre-preg material, electrically conductive circuit elements, and electronics, and has improved properties compared to woven glass and non-woven aramid products, including improved fiber consolidation, easy board construction, and improved MD/CD ratio and stability.
