COPPER ETCHING

Copper is the lifeblood of modern technology. From the power grids that light our cities to the microscopic circuits in our smartphones, its conductivity and versatility are unmatched. However, as components become smaller and more complex, traditional manufacturing methods often reach their breaking point.

​

At Metching, we provide a market-leading copper etching service designed to overcome these challenges, delivering rapid, miniaturized, and ultra-precise components from copper and its most specialized alloys.

​

The Hurdles of Conventional Copper Machining

 

Traditional fabrication methods often struggle with the unique physical properties of copper-based alloys.

​

• The Reflectivity Issue: Technologies like laser cutting often struggle with copper because the material is highly reflective. This can lead to inconsistent cut quality and even damage to the machinery itself.

• Mechanical Stress: Methods such as stamping or waterjet cutting rely on physical force or high-pressure impact. These processes can compromise material flatness, introduce "burrs" (rough edges), and create internal stresses that weaken the final part.

 

Why Chemical Etching is the Superior Alternative

 

Chemical etching (also known as Photo-Chemical Machining) uses a controlled chemical reaction to selectively dissolve material from a metal sheet. Unlike mechanical methods, this is a non-thermal and non-contact process.

​

The Benefits of the "Cold" Process:

​

• Stress-Free Results: Because there is no heat or physical impact, the copper retains its original material integrity. Parts remain perfectly flat and free of mechanical stress.

• Burr-Free Finish: The chemical process dissolves the metal uniformly, leaving smooth, clean edges that require no secondary finishing.

• Micro-Precision: We can achieve intricate designs and tight tolerances to within ±0.020mm, making it the ideal solution for the next generation of miniaturized electronics.

• Sustainability: We utilize sustainable etchants, ensuring high-performance manufacturing with a responsible environmental footprint.

Versatility Across Copper Grades

 

Not all copper is the same. Different engineering applications require specific properties like enhanced hardness or corrosion resistance. Metching offers a comprehensive service covering pure copper and a wide array of specialized alloys:

​​

• Beryllium Copper: High strength & non-magnetic  >>>  Springs, connectors, aerospace

• Nickel Silver: Corrosion resistance & aesthetic  >>>  EMI shielding, musical instruments

• Phosphor Bronze: Fatigue resistance & elasticity  >>>  Electrical springs, washers

• Brass: Low friction & malleability  >>>  Decorative trim, gears, valves

​

Powering Every Industry

 

Copper’s high conductivity, durability, and ductility make it indispensable. Every month, we produce thousands of etched components that serve as the backbone for the automotive, aerospace, and medical sectors.

​

Beyond etching, these components can be further formed, finished, and plated to meet specific industrial standards.

​

Typical Etched Copper Components include:

​

• Electronics: Contacts, pins, and connectors.

• Shielding: PCB shielding cans and Fingerstock gaskets for interference protection.

• Telecommunications: UHF/microwave antennas.

• Power Distribution: Busbars for electric vehicles and power grids.

• Semiconductors: Lead frames for integrated circuits.
