Heat dissipating through-holes, logos, and nomenclatures can be added. For easy rework and component access, two-piece designs with removable covers are available. Standard two-piece designs have a spring-finger-style attachment between fence and cover. Shielding is typically etched from 0.007 to 0.020-in. brass with tin plating. Multicavity designs are manufactured by incorporating internal fences that let multiple components be shielded with the same part. Onepiece designs use depth-etch bend lines for hand forming. Mounting options include solder through-hole, push-through retention pins, or SMT pad configurations. Low-profile options for portable, handheld applications and smaller form factors are available.
