What are Two Piece Surface Mount Shields?

Two Piece Surface Mount Shields are PCB EMI/RFI shielding solutions consisting of a frame and removable cover. They provide electromagnetic shielding while allowing easy inspection, tuning, and repair access.

What are the advantages of two piece surface mount shields?

Two piece surface mount shields allow easy access to PCB components for inspection, tuning, testing, and repairs without removing the entire shielding structure from the board.

Are Two Piece Surface Mount Shields compatible with automated PCB assembly?

Yes. Two Piece Surface Mount Shields are designed for automated pick-and-place assembly processes and support efficient high-volume PCB manufacturing.

What materials are available for two piece EMI shields?

Two Piece Surface Mount Shields are available in materials such as pre-tin plated steel and Alloy 770, depending on the shielding and application requirements.

When should I use a two piece PCB shield instead of a one piece shield?

Two piece PCB shields are ideal when applications require repeated inspection, tuning, troubleshooting, or repair access after assembly.

What industries use two piece surface mount EMI shields?

Two piece surface mount EMI shields are commonly used in telecommunications, aerospace, medical devices, automotive electronics, industrial equipment, and consumer electronics.
