Abstract
An electronic cartridge which has a fastener that can attach the cartridge to a motherboard. The fastener is captured by a cover that also captures a substrate. The substrate may be coupled to a connector that is mounted to the motherboard. The fastener may be attached to a retention mechanism that is also mounted to the motherboard. The fastener may have a threaded portion that is screwed into a corresponding threaded aperture of the retention mechanism. The fastener and retention mechanism provide a rugged attachment of the cartridge to the motherboard. The cover and retention mechanism may be constructed from an electrically conductive material which provides a shield to electro-magnetic interference (EMI).
Claims23
An electronic cartridge, comprising:
- a substrate;
- an integrated circuit package mounted to said substrate;
- a cover that captures said substrate and defines a first key surface at a first plane and a second key surface at a second plane, the first plane being different than the second plane, to mate with a retention mechanism having a first key surface uniquely matched to the first key surface of the cover and a second key surface uniquely matched to the second key surface of the cover;
- and,
- a fastener that is captured by said cover.
An electronic assembly, comprising:
- a motherboard;
- a connector mounted to said motherboard;
- a retention mechanism mounted to said motherboard;
- a substrate which is coupled to said connector;
- an integrated circuit package mounted to said substrate;
- a cover that captures said substrate and defines a first and a second key surfaces at different distances from the motherboard to mate with a retention mechanism having a first key surface uniquely matched to the first key surface of the cover and a second key surface uniquely matched to the second key surface of the cover;
- and,
- a fastener that is captured by said cover and attached to said retention mechanism.
A method for assembling an electronic assembly, comprising:
- a) mating a substrate of an electronic cartridge with a connector that is mounted to a motherboard by keying a first surface on the cartridge with a first surface on the connector and a second surface on the cartridge with a second surface on the connector, the first and second surfaces on the connector being at a different distances from the motherboard;
- and,
- b) fastening said electronic cartridge to a retention mechanism that is mounted to said motherboard with a fastener.
