GORE® SNAPSHOT® EMI Shield Application Summary: PCMCIA Express Card


Enlarge

Reduce product size with custom-designed board-level shielding

Application Overview

A customer was developing a new PCI express card for 4G Orthogonal Frequency Division Multiplexing (OFDM) technology. Key issues for this application include the following:

  • Low-profile product design
  • Co-planarity interference
  • Reliable data transmission

The customer originally specified traditional metal cans for shielding; however, once incorporated into the design, they did not meet the height specification for the card.

The Gore Solution

GORE® SNAPSHOT® EMI Shields are lightweight, multicavity shields that allow the customer to reduce product size by varying the height of the shield within each cavity. Using these shields reduced the height of the PCI express card design and eliminated any possible co-planarity issues. At the same time, these shields ensure excellent signal performance up to 12 gigahertz.
