At higher frequencies the preference of EMI/RFI engineers turns to more Hermetically Sealed Shields. Drawn EMI/RFI shields provide a seamless protective cage. These shields are fabricated as drawn frames with drawn snap on covers. As opposed to bent frames & covers which can be fabricated single by manual process these shields must be tooled.
Drawn EMI/RFI Shields main advantages:
> Seamless protective cage Promotes high shielding effectiveness
> Robust & Solid Construction Resists warping during transit and handling
> Optimal planarity Promotes high yield on reflow soldering
> Two-piece shield Design (Frame & Cover) Enables users the flexibility to inspect or repair shielded components without having to risk board damage by removing the entire shield or incur any tooling costs.
Why to use Standards?
Masach׳s Drawn EMI/RFI Standard Shields maximize flexibility of design for surface mount configurations in situations where engineers are aware of potential interference during the board design phase. Ordering a standard product eliminates the design of the shield and the production of prototypes for evaluation.
Added advantages are translated relatively low cost and short delivery times.
In addition, complimentary CAD files are available for download on Masachs website for immediate use.
