RCC Materials: Resin-Coated Copper Construction

RCC means resin-coated copper; flexible RCC products are one specific construction within this category. Material reference.

Resin-Coated Copper Construction

For a thin build-up layer, identify resin chemistry, copper foil and finished dielectric thickness before comparing it with prepreg or a standalone film. Do not assume that one flexible RCC product's processing requirements apply to a rigid-board material from another supplier.

Manufacturing and acceptance checks

Request the exact product and resin state, copper profile and thickness, storage requirements and lamination guidance. Define via formation and metallization with the fabricator. Approve electrical, adhesion and reliability evidence for the finished stackup before changing resin or foil under a generic RCC callout.
