Etching EMI/RFI Shielding: We’re the Experts

Etching Experts

Switzer uses a multi-step photochemical etching process to produce precision crafted EMI/RFI shielding units. Since 1988, we’ve established ourselves as a trusted supplier to thousands of large and small commercial and military contacts. We have the expertise needed to provide our partners with quality microwave related components with lead times they can depend on.

EMI/RFI Shielding: Etching VS Other Manufacturing Methods

This precise, repeatable chemical etching method is a much more flexible process when compared with other methods and it is ideal for scaling production volumes efficiently. Our well-tuned etching process eliminates imperfections, such as burrs and stresses, that are common in other forms of manufacturing.

When compared to laser etching, chemical etching proves to be less expensive with faster lead times. This is because the chemical etching process can produce all features of multiple complex components simultaneously, while a laser can only etch one part at a time.

EMI/RFI Shielding: Low Risk, High Reward

One of the greatest advantages of photochemical etching is the low tooling costs. When compared to the hard tooling used in stamping, the digital tooling used in the photo etching process is inexpensive and more versatile.

Stamping requires expensive hard tooling that has a finite life cycle. Each time a hard tool is used, it slowly wears away and loses its shape. When this happens, the expensive tool must be replaced resulting in a loss of precious time and money. The digital tool used in chemical etching is a low-cost alternative, allowing EMI/RFI shield design changes easily, and long term/lifetime use is typical.

EMI/RFI Shielding, Filter Covers, and More!

Switzer has been involved in the RF and microwave industry for 30+ years, so we have extensive experience with numerous industry related components. Besides EMI/RFI shielding, we successfully produce:

  • Filter Covers & Lids (for single and multi-cavity filters)
  • Isolators & Circulators
  • Striplines/ Microstrips
  • Plated Contacts and Apertures
  • Antennas
  • Shims
  • Ground Planes & Enclosures

These components are essential for producing telecommunication equipment for aviation, aerospace, and military applications. We produce precision crafted components with extremely tight tolerances that our customers can depend on. Are you currently utilizing the benefits of chemical etching for your EMI/RFI shielding? We know your designs are specific; put our expertise to the test so we can show you what we do best.
