Abstract: A preferred embodiment of a ball-grid array connector includes a housing having a major surface with a first and a second portion. The housing has a first and a second penetration formed therein. The first and second penetrations adjoin the respective first and second portion of the major surface. The connector also includes a first and a second contact mounted on the housing and extending through the respective first and second penetrations. The connector further includes a first and a second fusible element attached to the respective first and second contacts. The first portion of the major surface is recessed so that the first fusible element is spaced apart from the housing.

Abstract: Electrical connectors and contacts for transmitting power are provided. One power contact embodiment includes a first plate that defines a first non-deflecting beam and a first deflectable beam, and a second plate that defines a second non-deflecting beam and a second deflectable beam. The first and second plates are positioned beside one another to form the power contact.

Abstract: Preferred embodiments of power contacts include two or more opposing contact beams of a first type that are spaced apart along at least a portion of the length thereof when the power contact is in an unmated state; and two or more opposing contact beams of a second type. The contact beams of the second type are spaced apart so that the contact beams of the second type pinch the contact beams of the first type when the power contact is mated with a mating contact, thereby causing the contact beams of the first type of deflect inwardly toward each other.

Abstract: A preferred embodiment of an electrical connector includes a housing, a wafer positioned adjacent the housing and being movable in relation to the housing, a first contact extending through the housing, a first fusible element mounted on an end of the first contact for securing the first contact to the housing and to a first location on a substrate, a second contact extending through the housing and the wafer and being movable in relation to the housing, and a second fusible element mounted on an end of the second contact for securing the second contact to a second location on the substrate so that the second contact can deflect substantially independent of the housing and the first contact in response to relative movement between the housing and the second location on the substrate.

Abstract: An electronic component extraction tool is provided. The extraction tool comprises two opposing deflectable arms connected to one another, each arm having an end with a first surface adapted to extend under a side edge of an electronic component and a second surface adapted to extend over a side edge of the electronic component. The tool further comprises a latch system comprising at least one latching projection on a first one of the arms adapted to engage a second one of the arms to latch the two arms and the ends in an inwardly deflected electronic component carrying position.

Abstract: Electrical connectors and contacts are disclosed. An electrical connector may include a housing having a contact receiving well that extends along a contact receiving direction, the contact receiving well having a generally T-shaped cross-section along a direction transverse to the contact receiving direction. An electrical contact may be received in the contact receiving well. The contact may include a generally planar body portion, a first contact portion extending from a first end of the body portion, and a second contact portion extending from a second end of the body portion. The contact is adapted to be received into a generally T-shaped contact receiving well such that the contact receiving well prevents movement of the electrical contact within the contact receiving well.

Abstract: Methods for setting contact height in an electrical connector are disclosed. Each of a plurality of electrical contacts may be seated in a connector housing such that each contact has a respective initial height relative to the housing. At least one of the contacts is pressed on such that, after the pressing, each of the contacts has approximately the same height relative to the connector housing. The pressing may bend the at least one contact at least until it has set. Before the pressing, the initial contact heights have a first tolerance. After the pressing the pressed contact heights have a second tolerance that is smaller than the first tolerance.

Abstract: A modular board to board mezzanine ball grid array BGA connector includes a plug, a receptacle and if needed an adapter. The plug and the receptacle can be made form the same base pieces to accommodate different stack heights. If a greater stack height is needed, spacers can be used in the plug and the receptacle to accommodates a greater selected stack height. The plug and the receptacle both include a base having an interstitial diamond recesses in which the solder balls are disposed and in which one end of a contact is inserted. The plug may further include a plug cover that can be connected to the base, and the receptacle may include a receptacle cover that fits over its base. The plug can have a plug contact assembly, and the receptacle can have a receptacle contact assembly. The plug and the receptacle can be mated by mating the plug cover to the receptacle cover and the receptacle contacts to the plug contacts.
