Abstract

This paper presents a method of detecting the presence of a solder paste deposit by a solder paste deposit dispensing machine using a reflective sen- sor. An advantage of this method is that it can also be used with dispensing needles that have a foot, unlike conductive or capacitive methods. Also with this method each solder paste deposit can be checked in accordance with a software program.
