Ground Blocks

Ground Blocks

Ceramic Ground Blocks are customizable conductive shims ideal for application within micro-assemblies in both optical and microwave industries.

Features

GB

  • Customizable size, thickness and metallization layers.
  • Low impedance at high frequencies.
  • Prevents creep-up of solder and epoxy.
  • Orientation recognizable at a glance.
  • Good thermal match with alumina substrates.

Uses

  • Height matching to reduce length of wire bonds.
  • Conductive shims used for creating bonding pads.
