Ground Block
Ceramic Ground Blocks are customizable conductive shims ideal for application within micro-assemblies in both optical and microwave industries.
Our ground blocks follow a different part numbering scheme from standard square type. Each part of the PN is structured as follows.
The electrode stackup we use for Ground Blocks is as follows.
