| Summary: | The process of surface modification and metallizing polyetherimide resin reinforced with 20% glass fibers was studied and characterized. The objective of the metallization was to eliminate the electromagnetic interference (EMI). The surface of the plastic was modified by etching the resin matrix and then the glass fibers using two different solutions. During the resin etching step, glass fibers were exposed at the surface and then removed by glass etching step. Glass fibers etching was found to be essential to promote adhesion between the metallic film and the resin surface. Also, the heat treatment to remove excess moisture and to relieve stresses was found to be an essential step immediately after the electroless deposition step. After electroplating, the adhesion force between the metal and the substrate was 230 kg/cm2 (3000 psi). Keywords: Plastic metallization, Metal adhesion, Polyetherimide, EMI
