Copper Clad Laminate

A copper clad laminate (CCL) is an insulating substrate, usually FR-4, with copper foil bonded to one or both faces: it is the PCB laminate that circuit traces are etched from. Our copper clad laminates provide the perfect combination of electrical conductivity and structural integrity, designed to meet the diverse needs of industries ranging from electronics to aerospace. With a selection of high-performance substrates, including G10/FR4, G11/FR5, Non-Brominated G10, and G9, these laminates offer excellent mechanical strength, thermal stability, and electrical insulation.

COPPER CLAD FR4

Our FR4 Copper Clad Laminates are a fire rated Electrical Grade, dielectric fiberglass material created under high pressure with electro deposited HTE (high-temperature elongated) Copper Laminated onto the FR4 substrate. It is commonly used for PCBs.

What Is Copper Clad Laminate?

Copper clad laminates combine a reinforced substrate with electro deposited copper to create a stable platform for electrical pathways, thermal management, and mechanical support. These materials are engineered to maintain consistent conductivity while providing the rigidity needed for fabrication, drilling, routing, and component mounting. The copper layer bonds uniformly to the substrate, supporting clean etching and reliable circuit formation.

Substrate Options and Performance Profiles

Copper clad materials are available on multiple reinforced bases, each offering distinct mechanical and thermal characteristics. Options include G10/FR4, G11/FR5, Non Brominated G10, and G9. These substrates provide varying levels of heat resistance, dielectric behavior, and structural strength, allowing engineers to match material selection to electrical load, environmental exposure, and fabrication requirements. The copper layer is available in multiple weights to support signal integrity, current carrying capacity, and thermal dissipation.

Role in Electrical and Electronic Assemblies

Copper clad laminates are the foundational PCB laminate for printed circuit boards, and also go into electrical insulation structures and precision electronic components. Their stability under machining and thermal cycling makes them suitable for:

PCB fabrication
Insulating plates with conductive pathways
High temperature electrical assemblies
Prototype and short run circuit development
Structural components requiring integrated copper surfaces

The combination of mechanical strength and electrical functionality supports both low volume development and high volume production environments.

LAMINATES FOR PCBs AND PCB INSULATORS

These specialized copper clad laminates, or Electrical Grade Laminates, are manufactured by Current Composites here in the United States. We offer competitive copper clad laminate pricing, excellent quality, and reliable delivery. We specialize in custom thickness, coppers and colored applications for short runs, prototypes, and production runs.

Our Warren, OH facility manufactures these highly specialized copper clad laminates, which makes us one of the few copper clad laminate manufacturers and suppliers that still operate their own manufacturing facility in the U.S.
