Precision Copper Chemical Etching Services ISO Certified Manufacturer

Copper Characteristics
Copper's superior electrical conductivity, thermal transfer properties, and corrosion resistance make it ideal for electronic components, EMI shielding, and industrial applications. Our photo etching process enhances these inherent advantages through precision manufacturing.

What is Photo Chemical Etching?
A subtractive manufacturing process combining photolithography and chemical etching to produce burr-free, stress-free metal parts with exceptional accuracy (±0.01mm). Ideal for complex designs that traditional machining cannot achieve.
