Abstract
Abstract This invention relates to a device which electrically connects a leadless integrated circuit package to a printed circuit board. More particularly, the device includes a square frame having a plurality of "S" shaped contacts arranged along each side of the housing. The lower end of the contact electrically engages a circuit on the printed circuit board and the upper end electrically engages a circuit on the package. The frame further contains positioning and support clips which permits alignment of the package before engagement is made with the S shaped contacts.

Claim 1
Independent Claim
195 words
A device for connecting a leadless integrated circuit package to a printed circuit board, which comprises: a. a square frame having a large center opening for receiving the integrated circuit package and having on each side defining the center opening a plurality of cavities which open out onto the inside face wall of the sides; b. a plurality of S shaped contacts, each positioned in a cavity with the S curve portion vertically positioned therein, said contacts having an upper contact point projecting out through the cavity opening, said upper contact point adapted to engage a pad on the integrated circuit package which may be placed in the center opening in the frame, said contacts further having a lower contact point which is adapted to engage a pad on the printed circuit board thereby providing an electrical connection between the integrated circuit package and the printed circuit board; and c. a bracket positionable on top of the frame and a integrated circuit package which may be placed in the center opening, said bracket and frame having aligned means thereon to fasten the bracket to the frame thereby securing the integrating circuit package to the frame.
