NOZZLE, SYSTEM AND METHOD

Abstract:

A nozzle for directing a stream of solder during a soldering operation is disclosed. The nozzle comprising a body portion having an inlet for receiving a supply of solder; an outlet portion having one or more outlets for dispensing solder therefrom; and at least one channel fluidly coupling the inlet to the one or more outlets. Therein the outlet portion is adapted to be arranged above the inlet, such that, in use, solder flows from the inlet to the outlet portion along the at least one channel in a generally upward direction. The outlet portion has first and second over-flow sections, each over-flow section being integral with, or connected to, a peripheral edge of an outlet of the one or more outlets, such that in use, the solder is dispensed from an outlet of the one or more outlets and flows over the first and/or second over-flow section. At least a portion of the first over-flow section has a first width, such that in use, solder flowing over the first over-flow section produces a stream of solder with a width substantially corresponding to the first width. At least a portion of the second over-flow section has a second width, different to the first width, such that in use, solder flowing over the second over-flow section produces a stream of solder with a width substantially corresponding to the second width. A method of manufacturing a nozzle of this type and a method of soldering a component with a nozzle of this type are also disclosed.
