RF shielded encapsulation of electronics

Effective RF shielding solutions are possible to achieve with Proofcap laminate.

Up to 60 dB dampening, or more, has been measured for telecom applications. The Proofcap cover is connected to the PCB with short-circuiting strips and cavities easily formed to separate functions and sectors on the PCB.

The electrical contact between Proofcap cover and PCB as well as metal surfaces are well protected by the melted inner plastic film. This results in long term effective shielding properties. The short circuiting strip is integated in the Proofcap cover and thus reduce the the number of extra items and operations. Conductive gaskets and metal surfaces often detoriate quickly and require correct contact pressure.

Proofcap shielding saves weight when compared to casted aluminium boxes and pottings in epoxies or polyurethane.

A 100 mm x 100 mm Proofcap cover weighs typically 20 grams
