BMI-S-608 one-piece board level shields with spring fingers

Highly economical Laird™-brand BMI-S-608 is a new one-part EMI shielding solution with an exciting range of current and potential applications within the automotive sector. More end markets are anticipated. Its four-sided shield frame is designed to remove complexity from the thermal transfer chain. There is no need for a top-mount cover thus saving materials costs for customers.

Instead, the diecast/heat sink main housing (from a separate manufacturer) is placed directly inside the shield frame and is clasped tightly by integrated contact spring fingers. BMI-S-608 provides cost-effective EMI shielding of components while its spring fingers create electrical contact and grounding of the diecast/heat sink. 

The snug fit sealing of the diecast housing ensures it will retain direct, surface-to-surface contact with high thermal load integrated circuits. 
BMI-S-608 enhances design freedom involving PCB layouts, permits tighter spacing between adjacent shields, enables easier repairs of components, and serves as an alternative to multi-component manufacturer solutions.
