Abstract: The semiconductor casing comprises a flat, electrically conducting grid forming a central platform to support the semiconductor chip. Electrical connection terminals are distributed around the platform. Each has a reduced thickness section between thicker end portions, facilitating its anchorage within the insulating material used to encapsulate the chip and connection wires. The semiconductor casing comprises a flat grid made of electrically conducting material, with a front and rear surfaces, forming a central platform and extended electrical connection terminals distributed around the platform. The connection terminals (4) of the grid (2) each comprise an inner section (5) and an outer section (6), the back surfaces of these sections forming part of the back surface of the complete casing. The inner and outer sections are joined by a reduced thickness section (7), with the reduction causing an indent (8) on the rear surface. Electrical connection wires (12) link the front surface (5a) of the inner sections to the terminals of the circuit chip (11) mounted centrally on the platform of the grid.

Abstract: Barrel comprises tube (30) of a dielectric material with inner diameter substantially equal to outer diameter of lens housing; >= 2 bumps (32) extending radially towards the inside of the tube and forming bearing surfaces for a periphery of the lens in a same radial plane; first metallizations (35) extending on the bearing surface and into first channels (38) in an internal wall of the tube towards its end; and second metallizations, each of which forms a contact area on a portion of the internal wall of the tube to bear against a lateral surface of the lens and extends towards the tube end. An independent claim is included for a method comprising forming a cylindrical tube of non-conductive material, including forming a bump extending inward from an inner wall of the tube, and forming a channel extending in the inner wall of the tube from the bump to an end of the tube; depositing a first metallization on a bearing surface of the bump and an inner surface of the channel; and depositing a second metallization extending along the inner surface of the tube to its end.
