Embodiment Construction

[0036] Figure 1-2D An electrical connector 10 of a preferred embodiment of the present invention is shown. These figures each refer to a common coordinate system 11 drawn therein. The electrical connector 10 includes a connector body 14 and a plurality of terminal pins 16 that together form a high density grid array of pins. The electrical connector 10 is used to establish electrical contact between a circuit substrate, such as a printed circuit board (PWB) 17, and an electrical component or a second circuit substrate (not shown).

[0037] The electrical connector body 14 includes a main portion 18 having a first substantially planar surface 18a and a second substantially planar surface 18b. The electrical connector body 14 also includes a plurality of posts 22 protruding from the second surface 18b. Post members 22 and main portion 18 are formed of an insulating material such as plastic, and preferably liquid crystal polymer (LCP). Post 22 and main portion 18 are prefera...

Abstract

A presently-preferred electrical connector comprises an electrically-conductive terminal pin 16, and an electrically-insulative connector body comprising a first 18a and a second 18bsubstantially planar surface and a stud member 22. The stud member projects from the second substantially planar surface and is adapted to be mounted on a circuit substrate 17. The connector body has a through hole formed therein. The through hole extends from the first substantially planar surface to the stud member and is adapted to receive the terminal pin. At least a portion of the stud member is coated with an electrically conductive material 44 adapted to establish electrical contact between the terminal pin and an electrical connection point 17a on the circuit substrate.

Description

technical field [0001] The present invention relates to electrical connectors, and more particularly to high density pin grid array (PGA) connectors. Background technique [0002] The continual pursuit of reducing the size of electronic devices, as well as adding additional functionality to these devices has resulted in a continual increase in the density of electronic circuits. This increase in circuit density and functionality reduces the area available for mounting electrical connectors on printed circuit boards and other types of circuit substrates. This development has created a need for a multi-pin electrical connector with minimal spacing of the terminal pins. A high-density PGA connector was developed due to such a need. [0003] A ball grid array (BGA) connector is a commonly used type of PGA connector. FIG. 13 depicts a BGA connector 100 of the prior art. FIG. 13 and other figures included herein, each refer to a common coordinate system 11 . The connector 100...
