Top Tips for Avoiding Re-tightened Fasteners on RF Shields

Silicone form-in-place (FIP) electromagnetic interference (EMI) shielding gaskets have a job to do. The electrically conductive FIP gasket bridges the gap between machined aluminum shields and PC boards create a faraday cage. When designed correctly, machined aluminum shields with conductive FIP gaskets provide effective EMI protection for sensitive electronics. What does “designed correctly” mean? There are obviously many factors that affect shielding performance. They’re all fun and exciting to talk about, but our focus in this blog post is on the use of mechanical compression stops to help avoid gasket related issues.
