ABSTRACT:
In accordance with a preferred embodiment of the present invention, a concavity of an elliptical shape is formed in a chisel-shaped soldering tip to create a reservoir in which a quantity of molten solder is retained by surface tension. In a preferred method of use, the leads of an electronic component and the lands of a circuit board to which they are to be electrically connected are pretreated with flux. The tip, with a blob of solder in its concavity, is drawn along the lead/land region with the blob of molten solder making contact therewith, so that molten solder is wicked into the region, and joints are formed between the leads the lands.
