EMC shielding
We specialize in custom metal components and have extensive experience in manufacturing EMC shielding, frames, bushings, gaskets, and other shielding elements.
Etched or laser-cut EMC shielding
EMC shielding is used to protect electronic components from external electromagnetic signals or to prevent interference with surrounding components or devices (EMI). Conductive materials such as copper or aluminum are often used for this purpose.
These are often mounted manually or automatically on circuit boards in a pick & place assembly line.
Our experienced engineers support you with your development projects. This can include material suggestions or the design of a complete shield, optimized for your requirements.
EMC shielding and more
Our chemical etching production method offers the unique ability to design complex geometries, such as custom ventilation hole patterns, without additional costs for expensive tools.
We offer the design, etching, and bending of prototypes as well as large-scale production, all from a single source.
Further services:
- Packaging in cardboard boxes, trays, or tape & reel
- Etched product identification with logo or part number on your shields
Adapt your EMC shielding to your PCB design, not the other way around.
Photochemical etching process for precision metal parts
Photochemical etching produces highly precise metal components with the finest structures and complex geometries. The technology works with extremely tight tolerances, very thin metal sheets, and burr-free results. This enables components that are often not possible with other processes. The finest structures are etched directly from thin sheet metal. The process is characterised by excellent repeatability, high precision, and industrial scalability.
In photochemical etching, metal is structured using a precise lithography and etching process.
The finest contours are created directly from thin sheet metal. The process enables complex geometries without mechanically stressing the material.
The result is stress-free, burr-free components with very high dimensional accuracy.
Our etching process offers virtually unlimited design freedom.
Photo-etching can be used to create a wide range of structures – for example:
• Filtered structures
• See-through structures
• Sharp and smooth edges
• Channelled geometries
With specially developed mask technology, the etching progress can also be controlled in the third dimension.
This creates defined breakthrough geometries and complex components – for example, for lancets, scalpels, or blades in high-volume production.
Photochemical etching enables maximum precision while maintaining high production capacity.
Typical features of the technology:
• Extremely tight tolerances in the hundredths of a millimetre range
• Finest structures and thinnest metals
• High repeatability of results
• Industrial high-volume production possible
The combination of precise lithography and industrial production technology ensures stable processes and cost-effective manufacturing.
In reel-to-reel etching, metal parts are manufactured continuously in an endless strip.
The components are then available as metal strips wound onto reels and can be further processed automatically.
Typical characteristics:
• Metal strip thicknesses of approx. 25 µm to 400 µm
• Easy integration into automated manufacturing processes
• Defined markings or codings possible
The components can be singulated at the customer’s site or fed directly into the next process step.
Photochemical etching can be used to process various metals and alloys.
Standard materials:
• Stainless steel
• Copper
• Nickel
• And its alloys
Additional materials (depending on location):
• Aluminium
• Titanium
• Molybdenum
• Precious metals such as gold or silver
Typical process parameters:
• Material thickness: approx. 0.003 mm to 1.5 mm
• Minimum tolerances: down to ± 0.007 mm
• Minimum web width: approx. 0.5 × material thickness
These values are guidelines and may vary depending on the application.
Our standards are industry-leading
We operate in the world of tightest tolerances, hundredths of a millimeter, finest structures, thinnest metals, and most complex geometries. We etch custom metal components in industrial large series while adhering to the tightest tolerances.
We strive for the highest customer satisfaction through excellent quality. To ensure this, our processes are continuously monitored and further developed through strict quality controls.
