Abstract

1498605 Soldering HOLLIS ENG Inc 17 Feb 1976 [7 March 1975] 06055/76 Heading B3R In a wave soldering process, particularly for circuit board soldering, solder overflow from a wave 32 is collected in one or more sluices and discharged into a solder reservoir A below the level of solder thereof such that oxidation (dross formation) is minimized without the use of a protective film. As shown, solder is pumped into an inlet of a sump body and hence from a nozzle 14 to form the wave 32. The overflow is collected by plates 26 and directed between the plates and the exterior surfaces of the sump body. The sump body is partially submerged and the lower ends 29 of the plates 26 define, with the exterior of the sump body, sluices through which solder flows into the reservoir below the solder surface. Screws 12 abut the lower ends 29 of the plates 26 so providing an adjustable sluice gap. Horizontal perforated plates 9, 24 are provided in the nozzle and vertical perforated plates (17) in the sump body, the latter plates providing for a back pressure to allow for a uniform wave across the nozzle.
