ABSTRACT:
Latent heat of fusion is used to store and extract a relatively large quantity of temperature controlled heat from the small volume of a soldering iron tip. This is accomplished by fabricating the tip from a composite material comprised of a porous metal matrix, the interstices of which have been filled with an element or alloy having a melting temperature at or near a desired working point. The latent heat of fusion associated with the change of state of this working substance provides a constant temperature reservoir of heat immediately adjacent to a heat consuming operation such as solder joint formation. This proximity of heat source and sink allows the formation of a series of solder joints with only minor tool temperature variation from one to the next, thereby contributing to a uniformity among them that is considered desirable. Also disclosed are appurtenances, fashioned from the same composite materials, that when appended to conducively shaped conventional tools invest them with much of the advantage just described.
