  • Patent number: 5005455
    Abstract: A method and apparatus for manufacturing preform panels having at least one preform for repairing interconnects, particularly for repairing meander-like interconnects with a preform plated with hard solder. The metal has at least the steps of: providing at least two successive punch events with a die; and performing a predetermined feed (V) between a metal band and the die between the two punch events, whereby the length of the feed (V) is greater than a die width of the die, a length of the die being shorter than a width of the metal band, and the preform being formed by a residual web of the metal band after the two successive punch events.

  • Patent number: 4912843
    Abstract: A method for repairing interconnect interruptions with congruent preforms. Congruent preforms that bridge an interconnect interruption are utilized for repairing interconnects whose width lies in the range from 50 through 70 .mu.m and whose course is fashioned meander-like. Interconnects having a width of about 150 .mu.m can be repaired with previous repair methods. Due to miniaturization of the interconnects, a special method for monitoring the congruent alignment between the preform and the interconnect at the location of the interruption as well as for monitoring the symmetrical bridging of an interconnect interruption is needed. This monitoring method occurs by monitoring with video camera, whereby the location of the interconnect interruption and the environment thereof, a preform that is congruent therewith, and the positioning of this preform relative to the interconnect interruption are viewed at different positions.

  • Patent number: 4229637
    Abstract: A spot welding assembly is disclosed particularly adopted for precision welding of small components. The welding rod is carried at an outer side of the entire assembly in a clamp portion of an electrode slide block. The electrode slide block is in turn slidably carried in a feeder slide block which is in turn slidably carried by a carrier fixture. An adjustable spring bias is provided between the feed slide block and the electrode slide block.
