Abstract: The present invention eliminates the release of vapors from an adhesive which bonds an organic multilayer substrate to a ceramic layer. Posts from the organic layer are plated up sufficiently high as to enter holes in the ceramic layer, but not completely penetrate through them. The holes may then be filled with solder, which both seals the holes against the escape of adhesive vapors and makes a good electrical contact with the post. A conductive pad may then be stenciled on top of the solder plug, and the chip or other electric component mounted to the pad. The hole is preferably plated with a conductive material prior to being filled with solder, so that solder may join the plating with the post. The solder plug is formed by forming a slurry of solder with alcohol, which is squeegeed into the holes and fused under pressure. A solder paste is then stenciled over the fused soldered power and is, itself, fused using the vapor phase.

Abstract: The present invention is a method of determining the crimp height of an electrical terminal being crimped to a wire during the production crimping cycle. The method includes collecting a plurality of force and position data element pairs which are measured and sampled during the actual crimping operation. These data element pairs, representing the work curve of the operation and are analyzed to find the position of the ram when the crimping die set just disengages the terminal being crimped. The position of the ram at this point is then translated into the crimp height of the crimped connection. The analysis of the data element pairs includes a filter to remove inconsistent or extraneous data element pairs which could adversely affect the result by indicating an erroneous crimp height.

Abstract: Disclosed is a horizontal extensometer for measuring strain on specimens in cryogenic to elevated temperatures with zero frictional and activation forces. The extensometer has first and second elongate hollow arms which are adapted to pivot in relation to one another in response to the increase in length of a test specimen when a strain is applied thereto. An increase between the points of attachment on the specimen produces a corresponding decrease in length at the opposite ends of the two arms, thereby producing movement through a standard linear variable differential transformer. A connecting rod which is highly rigid in the Y-axis but readily flexible in the Z and X-axes is adapted to pass through the center of the linear variable differential transformer to a moveable core and produce a measurement of the differential. The extensometer also employs a unique clamping mechanism which substantially reduces error caused by external forces. The extensometer of the present invention has near zero hysteresis.
