A soldering apparatus for selectively soldering designated areas on the surface of a printed circuit (PC) board for mounting multi-pin, through hole circuit components thereto includes a wave solder pot, a fixture for receiving and positioning the PC board over the solder pot, and a plurality of spaced nozzles disposed adjacent a lower surface, i.e., solder side, of the PC board. When actuated, the apparatus directs a solder flow through the nozzles to designated areas corresponding to the location of various components on the PC board. Each nozzle is configured and positioned to match the location and pin pattern of components to be soldered on the PC board for applying solder only to the local area, not affecting adjacent parts, and minimizing the amount of solder applied as well as limiting the temperatures to which the PC board is subjected. The apparatus may be used with either a foam or wave flux application to selected areas of the PC board. A preheater may be included to warm the PC board prior to selective soldering to inhibit board damage. A slide conveyor may be used to transport the PC board on the "X" axis and also permit controlled movement on the "Z" axis to a predetermined height.
Apparatus for mounting a plurality of electronic circuit elements on a printed circuit (PC) board wherein said circuit elements are disposed in a spaced manner on a first surface of said PC board and each circuit element includes a plurality of conductive pins inserted through apertures in said PC board and arranged in a given pattern, said apparatus comprising:
The apparatus of claim I further comprising elevation means for raising said plurality of nozzle means for applying molten solder to a lower surface of a PC board in a elevated position.
Apparatus for mounting and electrically coupling a plurality of electronic components in a spaced manner to a PC board, wherein each of said electronic components includes an array of conductive pins, said apparatus comprising:
The apparatus of claim further comprising control means for controlling the application of flux and solder to the PC board.
