Embodiment Construction

[0017] figure 1 An electrical contact fitting 2 and a conductive return element 4 according to an embodiment of the invention are shown. The electrical contact fitting 2 comprises an elongated tail portion 6 extending away from a body 8 of the contact fitting 2 . The conductive return element 4 comprises a first reflowable material 10 having an elongated tubular shape. Such as figure 1 and figure 2 As shown, the return element 4 is arranged on the electrical contact fitting 2 by pushing the tail portion 6 of the contact fitting 2 into the central opening of the tubular reflowable material 10 . Once the return element 4 is arranged on the tail portion 6, the lower end of the return element 4 is arranged adjacent to a corresponding conductive contact 12 of the substrate 14, which is for example image 3 The printed circuit board (PCB) shown. The reflow element 4 is then subjected to an elevated reflow temperature, causing the reflow element 4 to bond to the conductive subs...

Abstract

An electrical connector configured to be electrically connected to a substrate. The electrical connector includes a housing with a plurality of electrical contact terminals disposed on a connection surface thereof. Each electrical contact terminal includes an elongate tail portion extending from the connection surface. The elongate tail portion of each electrical contact terminal is disposed in a central opening of a tubular reflowable element. The tail portion may optionally include a stress or tension relief mechanism. The tubular reflowable element extends beyond a free end of the elongate tail portion away from the connection surface. The electrical contact terminals are configured to be disposed in the vicinity of a corresponding substrate terminal such that the reflowable element of each electrical contact terminal electrically connects the contact terminal to the corresponding substrate terminal.

Description

technical field [0001] The present invention relates to electrical contacts for providing an electrical connection between first and second electronic components, and more particularly, the present invention relates to electrical contacts having a refiowable element disposed thereon. Background technique [0002] Electrical connectors are often attached to a substrate, such as a printed circuit board, using a ball grid array (BGA) type of electrical connection. The BGA includes a plurality of solder balls for connecting the electrical contacts of the connector to the PCB. A typical BGA connector is connected to an array of electrical contact pads or traces arranged around the surface of the substrate. The solder balls are attached to the contact pads by first applying resin flux to the electrical contact pads, positioning the solder balls onto the electrical contact pads, and driving the connector through a reflow oven. During the reflow process, the solder balls are held ...
