摘要： A connector assembly has a plurality of electrical circuit members and interposer frames with resilient contact members pressed together by a centrally located actuation screw. The actuation screw is supported within a threaded hole in an actuation bar on one side of one of the circuit members. Turning the actuation screw in its threaded hole causes various parts of the connector assembly to be pressed together simultaneously under an evenly distributed load. A load distribution plate located between the actuation screw and the nearest circuit member reduces the bending stresses in that circuit member. Alignment bushings and pins extending through openings in the circuit members maintain the various parts of the assembly in proper alignment while the actuation screw is being turned.

摘要： A test apparatus and method for testing circuitized substrates such as printed circuit boards or ceramic substrates having one or more chips thereon. The apparatus includes one substrate (e.g., printed circuit board) located on a base and adapted for having another circuitized substrate (e.g., flexible circuit) positioned thereon and electrically coupled to conductive elements (e.g., copper pads) thereof. Elastomeric members may be used to force the flexible circuit against the conductors of the substrate being tested, this substrate positioned either within or upon a cover which is located over the flexible circuit and which assists in compressing the flexible circuit against the printed circuit board's conductive elements to assure positive connection therewith. The cover may also include elastomeric members to facilitate such connection and a pivotal arm for being actuated to engage the substrate being tested. Positioning as well as relative quick separation (removal) of the substrate is attainable upon completion of the testing.

摘要： A component can include a substrate and a conductive via extending within an opening in the substrate. The substrate can have first and second opposing surfaces. The opening can extend from the first surface towards the second surface and can have an inner wall extending away from the first surface. A dielectric material can be exposed at the inner wall. The conductive via can define a relief channel within the opening adjacent the first surface. The relief channel can have an edge within a first distance from the inner wall in a direction of a plane parallel to and within five microns below the first surface, the first distance being the lesser of one micron and five percent of a maximum width of the opening in the plane. The edge can extend along the inner wall to span at least five percent of a circumference of the inner wall.

摘要： Typical testing of solder joints, (e.g. joints at printed circuit board pads) has not proven totally predictive of the ultimate performance of such joints. It has been found that this lack of reliability is, at least in part, due to the tendency during testing for these pads to lose adhesion to, or delaminate from, the underlying substrate. In contrast, such occurrence is not typical of phenomena induced during typical device usage. To remove this source of unreliability, a test structure is made together with the manufacturing device lot. The same pad processing is used and the pad size is substantially enlarged in the test structure. The test structure is employed to predict performance of devices in the lot and then the lot is processed accordingly.

摘要： A semiconductor package is present along with an associated method. The package comprises a substrate with a top surface and a bottom surface, the substrate having a plurality of electrically conductive vias extending from the top surface of the substrate to the bottom surface of the substrate. A semiconductor device having an active surface, the active surface having a plurality of bonding pads, is attached to the substrate by an adhesive that bas holes that align with the vias. The vias are also aligned with the bonding pads. Solder serves to electrically and mechanically couple each of the bonding pads with a corresponding via. Each of the vias, in turn, is coupled to a solder ball formed on the bottom of the substrate.
