发明名称 Method and apparatus for applying adhesives to a lead frame
摘要 A method for applying a viscous material to a lead frame element. A method of the invention includes positioning the lead frame facing downward and bringing the lead fingers into contact with a pool of adhesive material. The contact of the lead fingers to the adhesive material results in a portion of the lead fingers receiving a portion of the adhesive material from the pool of adhesive material. The gravitational forces on the adhesive material on the downward facing lead frame maintain the shape and boundary definition of the adhesive material.
