Board Level Shielding - HYBRID

HYBRID is a two-piece customizable multi-zoned shield developed as a direct replacement to costly machined housings. HYBRID provides similar shielding performance to traditional machined enclosures but at a fraction of the cost. The innovative cover design and conductive foam gasket provide excellent inter-cavity isolation. HYBRID shields also require less board space and provide significant weight reduction versus machined parts.

 

 

 

 


           

Features

  • PCB Interface Options

    3G offer a variety of through-hole and surface mount attachment methods to securely bond the board level shield to the circuit board. Locating pins are placed on the bottom of the shield frame and mate to holes on the PCB. Locating pins are required for wave solder application but are also recommended for surface mount applications.

  • HYBRID Shield Isolation and Cover Retention

    Fasteners are used to secure the cover and provide effective compression of conductive gasket for improved inter-cavity isolation.

     

     

Material Selection Guide

The vast majority of board level shields are manufactured using Tin Plated Steel (Indoor Environments) or Nickel Silver (Harsh Environments). 3G builds millions of board level shields per year, and has the purchasing power to ensure the necessary raw materials are always in stock and available. Board level shields are also available in less common materials such as beryllium copper, phosphor bronze, copper, brass, stainless steel and mu-metal.
