Design Tips for EMI Shielding Corrosion Resistance

All design engineers should know that EMI gaskets are installed between mating flanges. They know this needs to happen to prevent electromagnetic radiation (EMI) from both leaving and entering the electronic enclosure. It is possible to use shields in humid and tempest environments because when choosing the correct gaskets, they can have a strong resistance to corrosion.

Here are three tips for enhancing corrosion resistance in EMI protections:

You must select the correct EMI gasket, which can help to slow down corrosion by offering lower galvanic currents. The material used matters, so consider pure silver, nickel-plated aluminum, and silver-plated copper. These three metals have a significant influence on corrosion resistance.

Surface treatments will help keep aesthetics and also to stop corrosion and oxidation. You can plate and paint metal enclosures while also finishing flange surfaces to enhance corrosion protection.

Secondary sealing is necessary at certain times. Adding extra moisture sealing when operating devices in salt, fog, or spray conditions because they all act as electrolytes and will corrode materials.

EMI Shielding

When engineers carefully select sealing, treatments, and materials, they significantly reduce corrosion and oxidation rates.
