ABSTRACT:
An apparatus for selectively tinning a zone of a plurality of leads overhanging a window of a substrate for a very large scale integrated circuit is provided, which employs a vise made up of a pair of hollow jaws forming a shaft when the jaws are in clamping position, wherein the shaft communicates with a supply of tin, a wave of tin being provided through the shaft to bathe the zone of the leads to be tinned, the apparatus further being adapted to send a jet of gas to the tinned zone of the leads.
