Metallic RF or thermal shield for automatic vacuum placement
First Claim
Patent Images
1. A shield for attenuating at least one of RF and thermal energy, the shield being metallic and having a center of mass, a perforated surface surrounding the center of mass, and a non-perforated area defined by the surface, the non-perforated area centered substantially on the center of mass and sized to permit pick-up and placement of the shield by an automatic vacuum pick-up and placement machine.

Abstract
A metallic RF or thermal shield (200, 200'"'"', 200") has a non-perforated area (202) around its center of mass, of a radius (203) sufficient for pick-up and placement of the shield by automatic vacuum pick-up equipment during automated surface-mount circuit assembly.

11. A surface-mount shield for attenuating at least one of RF and thermal energy, the shield being metallic and having a center of mass and a plurality of perforated surfaces including a first perforated surface surrounding the center of mass, the first perforated surface defining a non-perforated flat and smooth area centered substantially on the center of mass and sized to permit pick-up and placement of the shield by an automatic vacuum pick-up and placement machine, the non-perforated area being the largest non-perforated area defined by all said surfaces.
- 12. A shield for attenuating at least one of RF and thermal energy, the shield having a center of mass, a plurality of non-coplanar perforated surfaces one of which surfaces is located adjacent to the center of mass, and a non-perforated area defined by said one surface, the non-perforated area being centered substantially on the center of mass and being sized to permit pick-up and placement of the shield by an automatic vacuum pick-up and placement machine, said non-perforated area being the largest non-perforated area defined by all said surfaces.
