Abstract

In the figure there is shown a dispense nozzle holder 1 for a pick and place machine containing a nozzle 2 which, upon becoming in contact with a substrate surface 3, will dispense adhesive thereon. This arrangement of the nozzle 2 contacting the substrate 3 generally damages the nozzle 2 causing inaccu adhesive placement. In addition, the dispensed adhesive tends to stick to the nozzle 2 instead of the substrate 3. These problems were eliminated through the use of a set screw 4 threaded into the bottom of the nozzle holder 1. The set screw 4 is adjustable to permit an optimum offset between the tip of the nozzle 2 and the substrate surface 3. Thus, the set screw 4 now becomes the point of contact with the substrate surface thereby minimizing the above problems.
