Description
C11000 Pure Copper Foil Roll Strip Direct Supply For PCB Electrical Applications
Product Description

Our C11000 Pure Copper Foil is manufactured for applications requiring high electrical conductivity, superior ductility, and precise dimensional control. With a copper purity of 99.9% minimum, this copper strip is ideal for printed circuit boards (PCBs), electrical components, busbars, and grounding systems.

We offer direct factory supply with customizable thickness (0.05–0.15mm), width (≤600mm), and length (as required). Multiple tempers are available – from annealed (soft) to full hard – allowing you to match the material to your specific forming or stamping process.

All products comply with GB/T467-2010 and are manufactured under ISO9001, ISO14001, and ISO45001 certified processes.

How It Works
In PCB Manufacturing:

  1. Lamination – The copper foil is bonded onto a dielectric substrate (e.g., epoxy resin, FR-4) using heat and pressure.

  2. Etching – Unwanted copper is chemically removed, leaving the desired circuit pattern.

  3. Conduction – Due to ≥99.9% purity, the remaining copper traces carry electrical signals with minimal resistive loss.

In Electrical Components (Busbars / Connectors):

  • High conductivity (≥97% IACS) ensures efficient power transfer.

  • Proper temper selection allows bending or punching without cracking.

  • Rolled grain structure improves mechanical strength in hard tempers.

The combination of purity, flatness, and controlled temper makes C11000 copper the first choice for mission‑critical current‑carrying parts.

FAQ (Frequently Asked Questions)
Q1: Is this copper foil suitable for high-frequency PCBs?

A: Yes – for standard PCBs and many high-frequency designs, C11000 with ≥99.9% purity performs well. However, for millimeter-wave or ultra-low-loss 5G applications, we recommend discussing VLP or HVLP treated foils separately.

Q2: Can you supply widths wider than 600mm?

A: This product line focuses on ≤600mm for precision slitting and stamping. For wider rolls (e.g., 1270mm), please contact us – we have other production lines available.

Q3: What is the difference between annealed and hard temper?

A:

  • Annealed (soft) – Excellent for deep drawing, bending, and etching.

  • Hard – Higher tensile strength; holds shape better after stamping or forming.

Q4: Do you provide samples before a 1-ton MOQ?

A: Yes – trial samples (A4 size or small rolls) are available upon request. The 1-ton MOQ applies to formal production orders.

Q5: What surface finish is best for PCB etching?

A: A polished or standard rolled finish works well. For improved adhesion to resin, we recommend a customized surface treatment (please inquire).

Q6: How is the product packed for export?

A: Standard export package – moisture-proof paper, plastic-lined wooden pallets, and edge protectors to prevent damage during shipping.

Q7: What is your typical lead time?

A: 15–25 days after order confirmation, depending on quantity and temper/surface requirements.

Q8: Do you accept L/C payment terms?

A: Yes, we accept L/C at sight, T/T advance, or negotiable terms for long-term contracts.
