EMI Shielding gaskets are an essential part of modern electronics. Without these devices, important, life-saving electronic equipment could break due to EMI or RFI. To ensure the highest levels of safety, great care and consideration need to be taken when designing EMI shielding gaskets. There are many requirements to consider, and each one has important characteristics. It is important to remember that selecting important components, like materials, should be done during the design phase. You should avoid these issues to save a great amount of time and money. EMI shielding tapes are often used to reduce the cost of design while promoting strong and reliable EMI resistance

EMI Shield Tape

One of the most important considerations is the material choice. To get to the best material, you need to be able to answer three specific questions:

• What filler is needed?
• What shielding effectiveness is needed?
• Is galvanic compatibility a problem?

Although each job is unique to products and their environments, there are several standard materials.

Form-In-Place: this material is ideal when working with tiny gaskets that are thin and flimsy. Gaskets of this size are often difficult to manage, so FIP increases small electronics’ overall performance.

Rubber Materials: rubber materials are often sold as EPDM, silicone, or fluorosilicone. Filler materials of nickel and silver alloys are chosen after the base material is determined.

Beryllium Copper: this material is sometimes used when devices operate within a broad range of frequencies. To use this material, designs require both an opening and closing of an enclosure (to provide a stable compression set).
