The in?uence of spike rate and stimulus duration on brainstem noradrenergic neurons

The method of making an improved electrical connector and the resulting article of manufacture. The invention is directed to an improved method of bonding connector pins within a ceramic substrate to form a high strength force resistant bond therebetween. A bonding mixture is formed whereby between 0.5 to 10.0 parts by weight of copper within copper oxide particulates are mixed with 1.0 parts of silver within silver or silver oxide paticulates. In one form of the invention, the bonding mixture is formed into a pasty consistency by the addition of an organic binder. The mixture is then placed contiguous to openings formed in the ceramic substrate. Connector pins are inserted in the openings and the connector assembly is fired in an air or inert atmosphere at a predetermined temperature within the range 950 DEG to 1010 DEG C. The resulting bond between connector pins and ceramic substrate is highly force resistant. In another form of the invention, the bonding mixture is added to a molding resin. The combination is then cast into bonding sheets. The sheets are stamped out in a contour dimension equal to the ceramic substrate. The bonding sheets are placed contiguous to the ceramic substrate surface and the connector pins are inserted into substrate openings. The connector assembly is then fired as previously described to form the improved bond strength electrical connector.
