Copper Etching Parts 0.02-1.5mm Thickness ±0.03mm Tolerance for Electronics/Aerospace
Product Overview
Xinhsen Technology is a leading manufacturer of high-precision copper alloy etched components, specializing in photochemical etching for complex and delicate metal parts. Our copper alloy etching services are ideal for industries requiring excellent conductivity, corrosion resistance, and intricate designs, including electronics, telecommunications, automotive, and medical devices.
We work with various copper alloys, such as pure copper (C11000), brass (C26000), phosphor bronze (C5191), and beryllium copper (C17200), offering unmatched precision for RF shielding, connectors, lead frames, EMI gaskets, and decorative elements.
Key Features
Ultra-Fine Precision – Achieves 0.015mm line width and 0.03mm micro-holes for intricate circuitry and meshes.
Wide Material Selection – Pure copper, brass, bronze, and beryllium copper for different mechanical & electrical needs.
Burr-Free & Stress-Free – Chemical etching ensures smooth edges without mechanical deformation.
Fast Prototyping – 3-5 days for samples, accelerating product development cycles.
Cost-Effective for Complex Designs – No hard tooling required, ideal for low-volume/high-mix production.
Custom Finishes – Optional gold plating, nickel plating, anti-tarnish coating, or laser marking.

ISO 9001 Certified – Strict quality control for consistent, defect-free components.
Applications
Electronics: EMI/RFI shielding, lead frames, heat sinks.
Telecom: 5G antenna components, waveguide parts.
Automotive: Fuel cell bipolar plates, electrical contacts.
Medical: Precision surgical tools, diagnostic equipment parts.
Industrial: Filters, sieves, decorative metalwork.
FAQ
Q1: What copper alloys do you recommend for EMI shielding?
A: Beryllium copper (C17200) offers the best conductivity and spring properties, while phosphor bronze (C5191) is cost-effective for general shielding.
Q2: Can you etch ultra-thin copper foils (0.02mm)?
A: Yes! We specialize in thin-film etching for flexible circuits and delicate components.
Q3: How do you prevent oxidation on copper parts?
A: We offer anti-tarnish coatings, gold/nickel plating, or passivation for long-term protection.
Q4: What’s the MOQ for custom designs?
A: 100pcs for production orders (prototypes can be made with no MOQ).
Q5: Can you provide bending/forming after etching?
A: Yes! We offer secondary processing (stamping, welding, assembly) for finished parts.
