石墨泡沫墊片
石墨泡沫墊片
概述
石墨泡沫墊片是一種導熱的電磁幹擾屏蔽墊片，它將柔性泡沫芯與外層合成石墨層結合在一起。
它提供可靠的 EMI 接地和平面散熱，同時保持低壓縮力、優異的彈性和輕巧的結構——非常適合高頻、高功率密度電子組件。

Omnidirectional Conductive Foam Gasket
Overview
The Omnidirectional Conductive Foam Gasket offers full three-axis (X, Y, Z) conductive contact and shielding within a compressible foam core wrapped in metallized fabric or foil. It is designed to handle complex geometries and high-density electronics, delivering superior EMI performance in enclosure seams, connector interfaces, and compact modules.

Core Features & Benefits
Three-axis Conductivity — Provides electrical contact and grounding in all directions, ideal for fine-pitch and high-speed designs.
Low Compression Force — Engineered to establish reliable contact with minimal force and accommodate tolerant assemblies.
High Shielding Effectiveness — Achieves > 90 dB attenuation across broad frequencies in compact form factors.
Durable Construction — Metallized fabric resists abrasion, shear, and repeated closure cycles, ensuring long-term reliability.
Customizable Profiles — Available in die-cut shapes, slit strips, adhesive-backed formats and designed for odd-shaped or space-constrained applications.
Compliance — Flame-retardant, halogen-free, and RoHS-/REACH-compliant options available for rigorous regulatory environments.
