Abstract: An electrical circuit device having a ceramic substrate including a thick or thin film circuit on at least one surface thereof and an intersecting edge surface which may support termination leads anchored thereto and further retained by solder deposited upon an edge termination coating. The termination coating underlying the solder extends over the edge defined by the intersecting surfaces. The component resides in form of the substrate to include an indented area in the form of a notch or a groove which intersects both adjoining surfaces to provide a means of receiving edge termination material, so as to insure a continuous and non-interrupted deposit of the material to complete the electrical circuit between the leads and the respective circuit components of the circuit defined on the said one substrate surface.

Abstract: A method of assembling a packaged microcircuit with face-mounted leads includes forming a lead frame into a holder with opposed sets of leads turned upward and angular to spaced apart carrier strips, and securing a substrate having a microcircuit thereon within the holder with one set of leads securely held in contact with terminals on a face of the substrate, so that bonded electrical connections between the leads and the terminals can be readily made with conventional soldering techniques.

Abstract: An electrical circuit device having a substrate including circuit components on at least one side thereof and a plurality of through openings in the substrate. Terminal leads are positioned in the openings each with a deformation intermediate the ends of the leads and spaced internally of the opening from a soldered area at the juncture of the exposed portion of the leads and the termination edge of the substrate. Two methods of assembly of leads to the substrate are also disclosed.

Abstract: A packaged microcircuit includes a housing of insulating material having a plurality of apertures which extend from the interior of the housing to the outside. A metallized lead connection surface is formed on a wall of each aperture. A microcircuit having a plurality of terminals is disposed in the interior of the housing with each of its terminals aligned with a respective aperture. The individual leads extend into the apertures and are soldered to both the terminals and the housing. The first solder connection electrically connects each lead to the terminal aligned with the aperture and the second solder connection anchors each lead to the metallized surface of the housing to absorb mechanical stress applied to an outwardly extending portion of the lead.
