Struggling with failed EMC tests, mysterious signal noise, or gasket failures in the field? EMI shielding — using conductive materials to block unwanted electromagnetic interference — is often where the problem starts, and where the fix lives.
Over hundreds of enclosure shielding projects, we’ve seen the same two numbers separate reliable products from costly recalls: a 93–98% groove fill ratio and 15–25% gasket compression. Get these right, and most EMI headaches disappear.
In this guide, you’ll learn the four core shielding materials, field-tested design rules, a 6-step FIP selection framework, and a ready-to-use checklist — everything you need to design EMI shielding that passes the first time. Let’s dive in.
