Abstract: Apparatus and method for the uniform dispensing of a conductive epoxy binder in hybrid microcircuit applications. A method is disclosed of uniformly pressurizing a conductive epoxy binder through a small orifice until a droplet of fixed volume forms, setting a predetermined gap size between a contact pad and the droplet in order to control the shape and size of the epoxy droplet left on the pad as the droplet touches it, and then releasing the pressure while reciprocating the dispenser from the pad. Also, apparatus, including a cylindrical limiting means attached to the dispenser tip, is disclosed for ensuring the gap size is constant. Other embodiments of the limiting means provide for the use of a relieved section which assists in preventing contamination and for adjusting means operable to vary the gap size.

Abstract: A printed circuit card receptacle formed of one or more edge connectors having a pair of opposed, slotted card guides affixed thereto. The receptacle includes a mountable connector having a channel member at either end thereof for receiving the guide. Each card guide has a sleeve portion for slideably engaging the channel member and a releaseable locking means for holding the card guide affixed in place after full engagement of the sleeve with the channel member. The receptacle includes means for holding the printed circuit card in the connector.
