Copper Etching

Copper Etching

Copper is a widely used material for electronic components of many industries, which has an excellent thermal and electrical conductivity. It is soft metal, easy formable, and also much cheaper than silver.

There are several types of copper alloys, such as brass, beryllium copper, phosphorus bronze, nickel silver, the added compositions enable copper increase conductivity, strength and thermal properties.

We’ve provided vapor chamber made by etching copper for a lot of customers since 2010. Copper is soft and easy to be etched in tight tolerance.

Key Properties of Copper Alloys

  • Excellent heat conductivity.
  • Excellent electrical conductivity.
  • Good corrosion resistance.
  • Retention of mechanical and electrical properties at cryogenic temperatures.
  • Non-magnetic.

Advantage of copper etching

  • Material properties remain unchanged, stress free and burr free
  • No expensive tooling investment, flexible to revise design
  • Cost-effective for mass production
  • Short lead time for prototyping and production
  • High accuracy

Applications of Etching Copper
