Abstract: An apparatus and method of forming balls includes a metering device 2, a melting device 14 and a cooling device 20. The metering device 14 stamps a desired volume of solid material in the form of a slug 12 which passes through the melting device 14 where it is caused to levitate and transform state from a solid to a molten liquid. The molten liquid material 13 is released from the melting device 14 and descends through the cooling device 20 where it transforms state once again from a molten material to a solid material while maintaining a ball shape. A forming gas is passed over the molten material 13 in a direction opposite to the falling molten material 13. The balls 15 are finally cooled in a cooling bath 32.

Abstract: A high density connector (12 ) for connecting to circuitry on a flexible circuit substrate (16). The connector (12 ) includes a stiffener member (14 ) that is attached to the connector housing (36 ) so that the flexible substrate (16) is clamped therebetween. Tails (46) of ground buses (40) within the connector extend through flexible substrate (16 ) and through openings (48) in the stiffener member (14) and are bent over into recesses (58) to hold the stiffener member (14) and connector (12) firmly against the substrate (16) along the entire length of the connector. Pivotal levers (90) are provided to cooperate with the stiffener member (14) to secure connector (12 ) to a mating connector (18 ) in mating engagement when pivoted to a closed position, and to separate the connectors (12,18 ) with minimum bowing of connector (12) when pivoted to an open position.
