DYHARD® for printed circuit boards

The laminates used for printed circuit boards (CCL = copper clad Iaminates) are usually manufactured from glass fibre fabrics which are impregnated with epoxy resins, hardeners and accelerators. The impregnated glass fibre fabrics are dried and pre-cured in hot-air furnaces (B-stage). Several such pre-impregnated layers are laminated together at high pressure and cured at high temperatures into circuit boards. DYHARD® products can be used to meet FR-4, FR-3, CEM-1 and CEM-3 standards.
