Laird Technologies' removable top BLS (board-level shield), ReCovr, incorporates the functionality of a two-piece shield without the need for a separate frame and cover. The shield is specially designed with a locking mechanism that allows for easy removal of the shield cover when access to board-level components within the shield is required. The locking mechanism makes repair of components under the shield quick and easy by eliminating the need for removing the entire shield and reducing board re-work. The removable top shield also integrates the company's patented (US Patent 7488902) rigid corner board-level shield technology, which incorporates a new corner design that optimises component rigidity for increased part and printed circuit board firmness.
Snapping off the shield cover is accomplished by using a small starter hole for simple removal. This hand operation requires minimal force using a hook scriber or tweezers. After repair, replacement, or adjustment of internal components, the same shield cover is then snapped back on.
The shields are available in standard board-level sizes or custom configurations of length, width, and height. They stay intact throughout manufacturing, packaging, shipping, installation, and the solder process. Design options include ventilation holes, side cutouts, embossing and marking. The shields are rated to survive standard drop, shock, and no-rattle tests.
An online video tutorial is available for viewing on the company's website. The video demonstrates the use of a hook scriber at various angles to remove the shield cover. The shield cover is then reattached using an alignment tool.
