Electronic-grade glass fiber yarn

Fine yarn has individual filaments of 9 micrometres or less in the report's classification. It includes electronic-grade yarn and industrial fine yarn. Electronic yarn is converted into electronic fabric through warping, sizing, weaving and subsequent treatment. Fabric acts as insulation and reinforcement, helping support the substrate and control dimensional change. It is impregnated with resin, combined with copper foil and hot-pressed into copper-clad laminate (CCL); subsequent processing produces a printed circuit board (PCB). This explains the yarn-to-fabric-to-board chain in which Jushi's electronic materials participate.
