custom etching copper parts

Copper is one of the most widely used metals in custom etching due to its excellent electrical conductivity, malleability, and corrosion resistance. It’s ideal for applications across various industries including electronics, telecommunications, aerospace, automotive, and decorative arts. Its smooth surface and fine grain structure allow for precise and intricate patterns, making it the metal of choice for both functional and aesthetic components.

Some key advantages of etched copper parts include:

• Superior electrical conductivity – perfect for PCB and RF applications.

• Corrosion resistance – especially when used in high-moisture or chemically reactive environments.

• Dimensional stability – maintains structural integrity during and after the etching process.

• Fine detail reproduction – enables creation of complex, high-resolution patterns.

Our Custom Copper Etching Capabilities

At TMN Metal Parts Fabrications, we use advanced photochemical etching techniques to create high-precision copper parts. This subtractive manufacturing process allows us to remove material from a copper sheet without introducing mechanical stress, burrs, or deformation. We can produce complex designs with fine tolerances, down to microns, ensuring every component meets your design intent.

Our custom etching capabilities include:

• Etching thicknesses from 0.001" to 0.080"

• Minimum feature size as small as 0.002"

• Tight tolerances typically ±0.0005" or better

• Prototype to high-volume production

• Single- or double-sided etching

• Surface finishing options like plating, coating, polishing, and passivation

Whether you need a few prototypes or thousands of production parts, our team can deliver consistent quality, fast turnaround times, and responsive customer support throughout your project.

Applications of Etched Copper Parts

Our etched copper parts serve a wide range of applications across multiple industries. Here are some of the most common use cases:

1. Printed Circuit Boards (PCBs)

Etched copper is foundational in PCB manufacturing. We produce high-precision copper patterns for single- and multi-layer circuit boards with ultra-fine features, ideal for consumer electronics, industrial control systems, and telecommunication devices.

2. RF and Microwave Components

The low resistance and high-frequency performance of copper make it ideal for radio frequency (RF) shielding, antenna components, and waveguides. Our etched parts ensure optimal signal clarity and reduced interference.

3. EMI/RFI Shielding

Custom-etched copper foils and enclosures are used to block electromagnetic and radio frequency interference. We offer shielding solutions tailored to sensitive equipment in medical, aerospace, and defense applications.

4. Battery and Power Storage

We fabricate copper connectors, bus bars, and terminals used in energy storage systems, EV batteries, and power management components. These parts require high current-carrying capacity and robust mechanical strength.

5. Decorative and Architectural Applications

Etched copper is also prized for its aesthetic value. We create custom copper panels, nameplates, signage, and artwork with detailed etching that enhances interiors, building facades, and product branding.

Our Process: Precision from Start to Finish

Every custom copper etching project at TMN Metal Parts Fabrications follows a streamlined process to ensure quality, accuracy, and timely delivery.

1. Design & Engineering Support

We start by working with your engineering drawings or CAD files. Our experienced team will review your design, offer manufacturability advice, and make any adjustments needed to ensure optimal etching performance.

2. Phototooling

We create a photoresist stencil of your pattern, which is used to mask the copper sheet during the etching process. This allows for ultra-fine features to be reproduced accurately.

3. Etching

Using a controlled chemical process, we remove the exposed areas of copper. The result is a clean, stress-free part with sharp edges and consistent geometry.

4. Cleaning & Finishing

After etching, parts are cleaned, deburred, and undergo any requested finishing steps such as plating (nickel, tin, silver), protective coatings, or forming.

5. Inspection & Quality Assurance

Each part is inspected using precision measurement tools and visual checks to ensure it meets your specifications and performance requirements.
