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 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 contacts.
