  • Method and apparatus for mass soldering with subsequent reflow soldering
    Patent number: 4600137
    Abstract: An improved apparatus and method for mass soldering electrical and electronic components populating both the top and bottom surfaces of substrate circuit boards or the like in a single pass is described. The circuit boards pass through a mass soldering station first, and after a timed interval the circuit boards pass through a solder reflow station. The timed interval allows heat transfer through the circuit boards to reach its maximum.

  • Wave soldering system
    Patent number: 4208002
    Abstract: A mass wave soldering apparatus is described. The apparatus comprises a sump having upwardly diagonally extending front and rear walls, and a pair of vertical end walls which cooperate to form an upwardly extending open ended nozzle chamber of increasing plan area. A Z-shaped baffle screen is positioned within the nozzle chamber and distributes the molten solder pumped upwardly in the sump as a wide, smooth substantially unidirectional solder wave ideally contoured for high-speed production soldering.
