ABSTRACT:
One and two piece surface mount pin constructions include excess solder receiving channels. In the one piece construction an elongate channel is provided through a tubular pin which is flared or swaged at the lower end to form a base. In the two piece construction a solid pin is provided at a lower end with a uniform cross section in the form of a regular polygon, such as a square, hexagon or octagon. The resulting edges are press-fit against an internal surface of a sleeve which is also swaged at a lower end to form a base. The spaces between the sleeve and the flat or convex surfaces on the captured end of the pin provide the solder-receiving channels. A bead or shoulder on the pins can provide a stop for a vacuum nozzle. When a flared upper lip is used for this purpose it can also serve as a reservoir or well to receive excess solder beyond the amount that can be received in the channels.
