INTRODUCTION
The complexities of today's electronics pose several design challenges .
Resolving EMI needs to be balanced with space, weight and production
restraints . When designing a custom shielding solution, beginning in the
earliest stages of the application design allows effective elimination of EMI
while meeting all specifications .
Laird Technologies board level shielding experts work through all phases of
development . From design, rapid prototyping and pre-production through
production and automated packaging, Laird Technologies has the experience
to help speed a product to market and stay within budget .
To increase manufacturing throughout and reduce costs, Laird Technologies
has developed a proprietary in-line production process that includes part for-
mation, wash, assembly, inspection and automated packaging .
By integrating quality processes, board level shield quality and performance
is ensured from design stage through final packaging . One process is the
automated co-planarity inspection system . Laird Technologies replicates the
customer application by measuring shields in the same plane as the printed
circuit board . This is accomplished without "securing" or "touching" shields,
which could throw off measurement and/or deform parts . Laird Technologies
measures shields immediately prior to placement into carrier tape at speeds
that match automation packing .
Shield base materials include our exclusive Shield-Lite TM , CRS 1008/1010,
beryllium copper alloys, nickel-silver alloys, copper-based alloys and spring
steels . All shields are fully solderable .

ONE-PIECE SHIELD DESIGN
Low Cost/Excellent Effectiveness
Custom surface mount shields are available in both one-piece and two-
piece designs . One-piece shields provide six sides of protection, with the
sixth side being the board itself . One-piece designs offer economical
shielding alternatives where access to covered components for repair is not
necessary .
TWO-PIECE SHIELD DESIGN
Quick, Easy Repair and Inspection of Covered Components
Two-piece board level shields offer users the flexibility to inspect or repair
shielded components without having to risk board damage by removing
the entire shield . Covers snap on and off with ease, making repairs quicker
and easier, and reducing board re-work . Two-piece shields are available
pre-assembled or unassembled . Large locking dimples snap into slots on
covers to provide mechanical retention force . Smaller grounding dimples
provide electrical grounding for proper shielding and to prevent rattle .
Two-piece shields survive drop, shock and no-rattle tests . Here are critical
test results:
•
