The Clamshell Gasket consists of an aluminum cover with a dispensed conductive silicone (Form-In-Place Gasket) on the edges. This eliminates the potential of RF leakage from substrate deformation and minimizes the number of screws required to maintain full contact with the PCB.


  • Applicable for both low and high volume applications
  • Metal frame can be used to dissipate heat
  • Increased board space due to thin wall requirement

Silicone additives available

  • Ag/Ni
  • Ag/Cu
  • Ni/Graphite

Aluminum housing options

  • Machined
  • Extruded
  • Die Cast

Plastic Shield Can | PCan

Pcan uses a molded plastic frame metallized with our proprietary Physical Vapor Deposition process with a conductive silicone edge to eliminate any potential gaps. Pcans are most commonly attached via screws and are an excellent solution for low cost multi-cavity applications.
