Abstract
An electrical assembly that may include a weighted cap. The weighted cap may provide counterbalancing to a non-proportional ball-grid array connector integrated circuit package for connection with a substrate. The weighted cap provides compensation for variations in the imbalance of the electronic connector package against the substrate.
Claims19
A system, comprising:
- a cap for a right-angle ball-grid array electrical connector, comprising a body, said body comprising:
- a substantially planar first surface suitable for vacuum pickup;
- a second surface formed to engage the electrical connector and defining a recess that receives the electrical connector;
- first and second portions positioned on opposite sides of the recess;
- a third portion that includes the second surface;
- and a center of gravity and a geometric center, wherein the first and second portions are thicker than the third portion, and the first portion weighs more than the second portion so that the center of gravity is offset from the geometric center and the cap balances the electrical connector on a substrate when the cap is placed on the electrical connector;
- and
- the electrical connector.
5 more elements
A system, comprising:
- a cap for balancing a right-angle ball-grid array electrical connector, the cap comprising a body capable of being mounted on the electrical connector, wherein the body has a first and a second side portion, and a substantially flat surface suitable for vacuum pickup, the body has a length greater than a length of the electrical connector, the body is non-symmetrically disposed about a geometric center of the body in a lengthwise direction of the body, the first side portion of the body has a first height so that the first side portion overhangs one side of the connector by a first distance, and the second side portion of the body has a second height greater than the first height so that the second side portion overhangs another side of the electrical connector by a second distance greater than the first distance when the body is mounted on the electrical connector, whereby the body exerts a moment on the electrical connector, and the first side portion faces the second side portion so that the first and second side portions define a continuous recess that receives a portion of the electrical connector;
- and
- the electrical connector.
A system, comprising:
- a cap for balancing a right-angle ball-grid array electrical connector, the cap comprising a body capable of being mounted on the electrical connector, wherein the body has a substantially flat surface suitable for vacuum pickup, the body has a recess formed therein that extends continuously across an entire width of the body and receives substantially an entire length of the electrical connector, and a center of gravity of the cap is offset from a geometric center of the cap so that a combined center of gravity of the cap and the connector is located at a different position along a length of the electrical connector than a center of gravity of the electrical connector;
- and
- the electrical connector.
