Specifications of of copper plate clad laminated sheet high pure copper flat sheet foil copper

High-Purity Copper Plate Dressed Laminated Sheet

Product Make-up

This product utilizes high-purity copper with a minimum purity of 99.95%. The base product is a level copper sheet or aluminum foil, bonded to one or more layers of shielding substrate. Typical backing products include FR-4, polyimide, or ceramic-filled laminates. The copper layer remains devoid of oxides and surface contaminants to support trusted electric efficiency.

Measurements and Resistances

Copper density varies from 0.025 mm to 3.0 mm , depending on application demands. Typical sheet sizes consist of 12″ x 18″, 18″ x 24″, and 24″ x 36″, yet personalized cuts are offered. Density resistance remains within ± 5% of the small value. Monotony variance does not go beyond 0.1 mm per 300 mm length , making certain consistent contact in setting up procedures.

Electric and Thermal Residences

The sheet reveals excellent conductivity, with an electric resistivity of ≤ 1.724 μΩ · centimeters at 20 ° C . Thermal conductivity reaches ≥ 398 W/(m · K), making it ideal for heat dissipation in power electronics. Surface area roughness (Ra) is maintained below 0.4 μm to minimize signal loss in high-frequency circuits.

Mechanical Attributes

Tensile toughness falls between 200– 250 MPa , while elongation at break is ≥ 10%. The bond stamina between copper and substrate surpasses 0.8 kN/m , avoiding delamination throughout thermal biking or mechanical stress and anxiety. Edges are deburred and smooth to avoid managing injuries.

Surface Complete and Taking Care Of

Both sides of the copper layer get a safety covering– generally anti-tarnish or passivation treatment — to keep solderability and stop oxidation throughout storage. Sheets are crammed in moisture-barrier bags with desiccants. Shop in a completely dry, awesome area away from straight sunshine and harsh gases.

5 FAQs of of copper plate clad laminated sheet high pure copper flat sheet foil copper

Frequently Asked Questions About High-Purity Copper Clad Laminated Sheets

What is a copper plate clad laminated sheet?

It is a flat sheet made by bonding a layer of high-purity copper to another material, often used in electronics or industrial applications. The copper surface stays clean and conducts electricity well.

Why use high-purity copper instead of regular copper?

High-purity copper has fewer impurities. This means it conducts electricity and heat better. It also resists corrosion longer and works more reliably in sensitive circuits.

Can this material be bent or shaped easily?

Yes. The copper layer is soft and flexible. You can cut, bend, or stamp it without cracking. Just avoid sharp folds that might damage the bond between layers.

Where are these sheets commonly used?

They are used in printed circuit boards, electromagnetic shielding, heat exchangers, and battery components. Their stable performance makes them ideal for high-demand electrical and thermal tasks.

How do I store copper clad laminated sheets?

Keep them in a dry, cool place away from moisture and chemicals. Wrap unused sheets in protective film or paper. This prevents oxidation and keeps the surface clean for later use.
