  • Patent number: 5611475
    Abstract: Apparatus for applying solder to electrical or electronic components mounted in a horizontally oriented carrier, includes a solder bath, a pair of tracks (1,2) for guiding the carrier across the solder bath, and a device for urging the carrier along the tracks. The track has a first profiled region (12,19) for guiding a leading position of the carrier down towards the surface of the solder, and a second profiled region (16,20) longitudinally spaced from the first region, and laterally offset, for simultaneously guiding a trailing portion of the carrier down towards the surface of the solder, the profiles being substantially the same so that the carrier maintains its horizontal orientation while being moved vertically towards and away from the surface of the solder. The carrier moves on follower wheels which run along the tracks.

  • Patent number: 4856455
    Abstract: A carrier for dual-in-line packages to be wave soldered, comprises a frame with tracks into which the packages can be slid. The tracks are defined by aligned upper and lower "U"-shaped channel members providing rails. Each track is defined between adjacent pairs of upper and lower members. Gates at either end of the tracks control movement of the packages into or out of the carrier. The carrier can be loaded and unloaded by means of apparatus including an inclined ramp on which the carrier can be releasably located, the packages being fed into the top of the ramp to fill the carrier, and sliding to the bottom of the ramp to empty the carrier of soldered packages prior to re-filling. Movement of the packages down the ramp is controlled by gates.

  • Patent number: 4747532
    Abstract: A carrier for components to be soldered includes an upper frame pivotally connected to a lower frame. The upper frame includes longitudinal grid members interlocked with transverse grid members to define recessed zones with stepped corners to locate the components. The lower frame has slidably mounted strips with projections which engage the components when the lower frame is pivoted to a closed condition.
