where it is connected to feed air duct 22 which provides air from a source exterior to the containment hood the containment hood 18 could have any configuration as long as the adhesive application process can be suitably focused and contained the containment hood 18 has an adhesive port 24 through which a delivery tube 26 extends the delivery tube 26 communicates with an adhesive reservoir 28 at its first end 30 and a nozzle 32 at its second end 34 the nozzle 32 is preferably an atomizer nozzle capable of dispersing adhesive 36 supplied by the adhesive reservoir 28 at a particle size of 50 100 u03bcm adhesive may be supplied under pressure by use of a pressurized gas as a propellant a positive displacement pump or by other means known in the art air feed duct 22 above containment hood 18 is connected to a positive or ambient pressure clean filtered and of controlled humidity air supply as known in the art so that air 40 can enter the containment hood 18 and carry the atomized adhesive 38 downward the air 40 and atomized adhesive 38 mix in a mixing chamber 42 formed by the containment hood 18 an aperture panel or mask 44 covers portions of the leadframe 12 such as the leadfingers 16 in fig1 where atomized adhesive 38 is not desired below the leadframe 12 the vacuum system 20 provides a negative pressure zone such that atomized adhesive 38 is quickly drawn downward onto leadframe 12 with the excess pulled into the vacuum system 20 so that only the upper side of the leadframe is coated with adhesive by reduction of backspatter and to reduce lateral overspray potential the vacuum system 20 is shown to have a plenum 21 similar in shape to the.
