Abstract: A system of control is disclosed for an oval printing machine comprising a plurality of travelling pallets sequentially moved in a first direction on an endless path through a plurality of screen printing stations during a printing mode of operation in which the pallets pause at the printing stations, the system of control comprising: a print head controller associated with each printing station for storing parameters defining print head functions in the print mode and for controlling printing operations at the associated printing station responsive to the stored parameters; an index controller storing parameters defining index controller functions in the print mode and for controlling the movement of pallets through the printing stations in response to the stored parameters; and a master controller electrically connected to the print head controller of each printing station and to the index controller for directing the index controller to move the pallets and the print head controllers to perform printing op

Abstract: An improved semiconductor assembly includes a semiconductor die that is mounted on a carrier, such as a tape or a substrate, by means of an anisotropically electrically conductive adhesive. The adhesive forms an electrically conductive path between electrical conductors on the carrier and other conductors on the die so that the die can be probe tested before the adhesive is cured and before the die is permanently bonded to the carrier.

Abstract: A deflection yoke is mounted to a cathode ray tube by the use of two adhesives having different hardening rates. A first adhesive is applied between the yoke and the tube by a dispensing machine in a sufficient quantity to temporarily hold the yoke on the tube. A second adhesive having a hardening rate slower than the first adhesive is applied between the yoke and tube by the dispensing machine. The second adhesive purges the first adhesive from the dispensing machine. The quantities of the first and second adhesives are required to permanently mount the yoke to the tube. This arrangement may be used to assemble the yoke itself, as well as assembling the yoke and mounting it to a tube in the same operation.
