Laird Performance Materials offers customised, robust protection from harmful performance-draining EMI (electromagnetic interference). Its broad range of shielding products can be tailored to any application, offering noise suppression for a range of gigahertz frequencies.
The following are just some of the product ranges available:
• Board-level, surface-mount shielding in one- and two-piece designs. One-piece shields include six sides of EMI protection. Two-piece shields give users the flexibility to inspect or repair shielded components without risking board damage.
• Fabric-over-foam gaskets are ideal for applications that require low compression force but still need high conductivity and shielding attenuation. They deliver shielding effectiveness of >100 dB across a spectrum of frequencies in a variety of shapes and thickness.
• EcoFoam flame retardant gaskets provide X-, Y- and Z-axis conductivity, enhancing the shielding effectiveness needed to meet increasing microprocessor speeds. RoHS-compliant, these gaskets include a conductive PSA tape on one side.
• Silicone-based microwave absorbing elastomers and films designed for all environmental situations while lessening cavity resonance challenges. The product line operates at various frequencies, with single-band and broadband grades from a few hundred MHz to above 100 GHz.
• Microwave absorbing foam is a lightweight, cost-effective solution addressing today’s challenges in communication infrastructure. Single- and multi-layer designs consist of tuned absorbing layers with specific dielectric gradients to obtain the best possible matching with the impedance of air.

Editor's Choice Circuit & System Protection
As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
