(7) 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.
(7) 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.We have designed our two-piece shields to survive drop, shock and no-rattle tests.
In cases where there is a low incidence of repairable circuit defects, you may need to access shielded components. An economical solution is our line of EZ Peel shields. These one-piece shields feature an easy-to-remove top section that can be peeled back using simple tools for access to components. Built- flexibility controls the ease of removing the top, and our robust design delivers superior flatness. EZ Peel shields are designed to accept a snap-on cover in the same manner as our two-piece shields, following circuit repair.
Printed circuit boards with multiple circuit groups pose unique design challenges. Shielding these groups separately adversely affects circuit board real estate and increases part count. Our multi-compartmental shields allow you to replace three or more single shields with one shield divided into several walled compartments. Installing a single part reduces part count, along with production time through faster pick-and-place speeds. This allows you to reduce the number of parts you carry in inventory, which lowers youR overhead costs. Multi-compartmental shields feature internal dividing walls of one material thickness and meet all on-board shield requirements for FCC, VDE, CISPR and CE. They are available in two-piece designs, either ...
As microprocessor speeds continue to increase, so does the potential for EMI leakage through the smallest apertures in board level shields. Laird Technologies’ drawn board level shields are designed to provide additional near-field and far-field circuit isolation (attenuation) at higher frequencies by eliminating the apertures found in the corners of traditional board level solutions. Drawn board level shields utilize small ground trace sizes, thereby preserving space on the circuit board.The data set forth in all text, tables, charts, graphs and figures herein are based on samples tested and are not guaranteed for all samples or applications. Such data are intended as guides and do not reflect product specification for any specific part.
(11) From concept to placement, Laird Technologies has the expertise to deliver custom precision surface mount contacts. Using the latest computer simulation techniques, we provide properly designed contacts that ground, carry current and signals, and interconnect boards and devices.We do this by using basic geometric parameters (length, width, uncompressed height, compressed height, contact force) to conduct Finite Element Analysis (FEA) on your prospective design. With the FEA results, we can then identify the best design to optimize your product's operational performance.We also incorporate features to provide for placement and soldering of the contact onto the circuit board.
