What Is Copper Etching?
Low set-up costs and incredibly fast lead times make copper etching a go-to process in batch sizes of ones to millions.
Low Cost Tooling
The tooling for copper etching and its alloys is digital, low-cost and can be modified quickly. Many customers select copper etching because of the flexibility it provides for supplying samples in days rather than weeks or months.
Component features are etched at the same time so part/feature complexity is not an issue. The complexity of the profile does not affect the price… to process thousands of apertures or just the one, the price remains the same.
Right First Time
No heat or force is used when processing copper and its alloys, so the mechanical properties of the metal remain unaltered and parts are free from stresses and burrs.
Benefits Of The Copper Etching Process
While the conventional, industry-standard process of copper etching suffers from several serious drawbacks that make the process inconsistent and unreliable for large volume production, ACE’s unique process overcomes this problem.
Some of the benefits include:
- Smooth edge profile and smooth surface etch profile
- No surface burrs
- Tight tolerances possible ±10% of material thickness
- Complex geometries at no extra cost
- 1:1 aperture aspect ratio possible
- Thicknesses from 0.07mm to 2.5mm
- Part size up to 1500mm x 600mm
- Fast turnaround
- Serial production capacity
- No heat-affected zones
All Round Metal
Copper and copper alloys are an important group of metals with many excellent properties. They have good electrical and thermal conductivities, are easy to form and include some alloys with incredible strength (beryllium copper alloys) and corrosion resistance. The characteristics of copper alloys have resulted in ACE etching a wide range of parts for may different applications. They can be etched then formed or deep drawn into the most complex of shapes.
Due to its versatility, copper alloys are used in a wide variety of products in many industry sectors. When parts are etched in any of the copper alloy the process will not affect the mechanical properties of the metal, meaning the metal remains unaltered by the process. Areas of the surface can be etched or reduced and the metal shows no distortion or warping. Multi complex profile shapes can be etched and the edges will remain burr free.
ACE can etch in thickness of 0.005mm to 2.0mm in all copper alloys, in hardness’s from soft (annealed) to mill hard condition and to a maximum sheet size of 1500mm x 600mm.
