    Abstract: An apparatus for soldering printed circuit boards moving along a predetermined path of travel, comprises an upwardly extending nozzle member having an opening at its top end from which molten solder is caused to overflow to form an overflowing molten solder with which the underside surface of the printed circuit board is contacted, and an adjustable outlet member rotatably disposed in the opening to define an outlet extending in the direction transverse to the path of travel, so that by adjusting the angular position of the outlet member the orientation of the outlet may be varied for adjustment of the direction and height of the overflowing solder.

    Abstract: At least one chip type component is soldered to a printed circuit board by independent first and second nozzles which spout molten solder so as to form respective first and second solder waves, with the printed circuit board sequentially passed through the first and second nozzles. The first and second solder waves define therebetween a space and flow at least in a direction of movement of the printed circuit board and in a direction counter to the direction of movement of the printed circuit board, respectively. The second nozzle is disposed at a level higher than the first nozzle such that the printed circuit board is moved obliquely upwardly.

    Abstract: An improved method and apparatus restricts or limits dross formation in a soldering apparatus where liquid solder overflows such as wave soldering and the like. The improvement comprises a solder receiving tray positioned beneath at least a portion of liquid solder falling from an overflow or solder wave to a reservoir and a level control means limits the maximum solder level in the tray above a dynamic solder level in the reservoir, the solder level in the tray being a predetermined distance below the overflow to limit dross formation thus restricting dross recirculation.

    Abstract: A solder reflow machine for removing and replacing electronic components of the pin-grid array type having a large number of leads soldered into a very densely populated printed circuit board. The machine utilizes a heat-transfer liquid and a vacuum to remove the component from the board. The printed circuit board is positioned with the component facing downwardly. A tank containing the heat-transfer liquid is located below the printed circuit board. The apparatus includes a solder reflow head which has a component-engaging vacuum plate with a central opening that is in communication with a vacuum source through a pipe which is pulled downwardly to remove the component. The component is surrounded by a wall in combination with the bottom of the printed circuit board and seals off the liquid flow path. The heat-transfer liquid is pumped up through a pipe that extends into a storage tank so that it flows into, an input passageway in the solder reflow head over the component leads to reflow the solder and down an exit passageway.

    Abstract: The present invention is directed to a method for soldering each of a plurality of members (40), arranged in one or more parallel rows, to a separate one of a plurality of metallized pads (42) on a substrate (10), each pad being contiguous with a corresponding member. The method is initiated by tilting the substrate so that one end of each row of members and the metallized pads contiguous therewith are at a higher elevation than the other end. A stream (80) of molten solder and a dripping stream (88) of flux droplets are directed onto the substrate into the regions where the members are contiguous with the metallized pads. Simultaneously, the substrate is displaced relative to the streams along a path (96) inclined with respect to the horizontal and parallel to the rows of members so that the members and the metallized pads are successively coated with solder and then flux. The inclination of the substrate is such that the solder and flux flow downwardly, under gravity, past a successive one of the members and metallized pads. The force of gravity on the solder, together with the presence of the flux, is sufficient to break the surface tension of the solder between adjacent members to prevent a solder bridge therebetween.

    Abstract: A multi stage heater heats items on a conveyor so that they follow a predetermined temperature profile. The heater is used for printed circuit boards or the like when heated for soldering and avoids thermal gradients that can occur with heating different materials. The heater has a first heater for applying a first quantity of heat to items on the conveyor, a temperature sensing device for determining temperature of items leaving the first heater, a second heater downstream of the first heater and a control system which compares signals from the temperature sensing device with a predetermined temperataure profile to produce a first control output to control the first heater and a second control output to control the second heater so that items passing through the heater follow the predetermined temperature profile.
