Abstract:
1. An apparatus for applying adhesive material to one or more underside surfaces of at least one semiconductor component, comprising: an adhesive reservoir configured to provide an exposed surface of an adhesive material contained therein to each of one or more underside surfaces of at least one semiconductor component positioned thereover and to avoid contacting the exposed surface of the adhesive material with a bond wire surface of the at least one semiconductor component, the adhesive reservoir comprising at least one pool chamber for receiving the adhesive material and defined an upwardly facing opening, the adhesive reservoir shaped such that the exposed surface of the adhesive material may be supplied to a precise location above the upwardly facing opening, the adhesive material having a surface tension; at least one mechanism associated with the adhesive reservoir, the at least one first mechanism configured to level the exposed surface of the adhesive material at the precise location above the upwardly facing opening and to maintain the exposed surface of the adhesive material at a substantially constant height; a coating stencil configured to manipulate a difference in pressure between the adhesive material and ambient air to be equal to twice the surface tension of the adhesive material divided by a radius of curvature of the adhesive material as the adhesive material is extruded through the coating stencil; and at least another mechanism configured to bring a defined portion of the at least one semiconductor component in contact with the exposed surface of the adhesive material.
