POLYAMIDEIMIDE RESIN FOR A FLEXIBLE PRINTED WIRING PLATE HAVING THE EXCELLENT FLEXIBILITY AND FIRE RETARDANT PROPERTY, A METAL CLAD LAMINATE PLATE USING THEREOF, A COVERLAY, THE FLEXIBLE PRINTED WIRING PLATE, AND A RESIN COMPOSITION

摘要

PURPOSE: A polyamideimide resin, a metal clad laminate plate using thereof, a coverlay, a flexible printed wiring plate, and a resin composition are provided to secure the workability and the solubility before curing, and the solder dip resistance after curing.;CONSTITUTION: A polyamideimide resin for a flexible printed wiring plate is obtained by reacting an acid component with one anhydride and aromatic dicarboxylic acid, a diisocyanate compound, and a diamine compound. The molar amount of the anhydride is 0.4~0.8 for the amount of the acid component. A metal clad laminate plate(100) is formed by locating the polyamideimide resin(110) on a metal foil(120) in a layered form.;COPYRIGHT KIPO 2011
