Introduction

Products Description

Johan ECF (Elastic Conductive Foam)

Semi-Fold(SF) series - Super Thin Space Grounding with low CFD and surface resistance

Technical Data Sheet

Updated: May,2021


Description
This grounding foam is made of high-rebound elastomer base and super thin conductive fabric or film and suitable for high
requirement grounding in super thin space. Due to its unique structure, it shows low electrical resistance and stable physical
properties even after tough environment test.

Structure

Patent No: CN206619706U

Application

① RF Antenna Grounding（stable and low conductivity)
② LCD/OLED Grounding (Min CFD<[email protected] gap)
③ Replace shrapnel in super thin space grounding (Min Gap<=0.20mm)
④ Very small grounding area (Size<=5mmX5mm -resistance 90% lower than plating-conductive foam)
