Standard Circuit Board Shields for Reliable EMI/RFI Protection
Leader Tech’s Standard CBS line gives engineers a practical way to protect sensitive board-level components from EMI/RFI interference without starting from scratch. These configurable circuit board shields are available in multiple standard series, sizes, heights, materials, ventilation patterns, and mounting options to support both prototype and production requirements.
Using Leader Tech’s patented two-piece construction, each Standard CBS design includes a solderable fence and a removable cover. This allows the shield to deliver reliable EMI/RFI protection while still giving engineers and technicians access to components for inspection, tuning, repair, or maintenance.
Standard CBS products are designed to give engineers flexibility without the cost and lead time of a fully custom shield. Choose from standard sizes, heights, pin spacing, materials, ventilation patterns, and assembly styles to match your PCB layout and application requirements.
A secure board-level shield has to do more than fit the available space. It needs to stay in place during handling, testing, assembly, and field use. Leader Tech’s Standard CBS designs are engineered for strong cover retention, helping protect critical circuits while supporting repeatable performance across demanding electronic applications.
