Compound laminate for printed circuit boards

摘要

It includes two outer sheets of continuous-strand fiberglass fabric and a core of non-woven fiberglass formed by sheets of fiberglass paper, all sheets being impregnated with epoxy resin, and presenting at least one sheet of conducting material, on one or both outer sides; it is characterized in that it incorporates in the non-woven fiberglass core at least one intermediate sheet of fiberglass fabric impregnated with resin. It allows manufacturing of reliable printed circuits, even when using surface-mounted components, while at the same time its cost is relatively low; it is particularly suitable for the field of consumer and semi-professional electronics.
