Abstract: A carrier tape system for receiving, retaining and quickly releasing small components, such as singulated bare die or integrated circuit (IC) chips for automated assembly processing. The carrier tape system is comprised of a longitudinally elongated flexible carrier tape frame with a plurality of spaced apart aperture cavities and a pair of pressure sensitive adhesive tape rails affixed to one surface of the carrier tape frame with the adhesive surfaces facing into the aperture cavities of the carrier tape frame. Each PSA tape rail has a longitudinal linear side edge and a configured side edge, where the linear side edge is affixed to the surface of the of the carrier tape frame and the configured side edge extends into and overlaps the aperture cavities for adhesioning the back side of the small components. With the configured side edges of PSA tape rails, a range or adhesion levels can be achieved with the PSA tape rails in one fixed gap width location.

Abstract: An apparatus for feeding a carrier tape with successive sprocket holes and indexed pockets for carrying small components, and used in conjunction with various pick and place assembly machines for surface-mounting of the small components onto a printed circuit board or other assembly substrate. The apparatus has an interchangeable electronic feeder adaptable to various surface mount assembly machines and a set of height support adapters. The feeder has both a flip-chip and non flip-chip capabilities. The interchangeable electronic feeder further has a tape guiding assembly, an indexing assembly, an adjustable push-up tool assembly, and a flipping-converting assembly.

Abstract: A carrier tape system for receiving, retaining and quickly releasing small components, such as singulated bare die, integrated circuit (IC) chips, or other small components for automated assembly processing. The carrier tape system is comprised of a longitudinal elongated flexible punched carrier tape frame and a solid width of pressure sensitive adhesive (PSA) tape affixed to one side of the carrier tape frame. The punched carrier tape frame has a plurality of spaced apart aperture cavities therethrough. The solid width of PSA tape also has a plurality of spaced apart configured apertures which are smaller than the plurality of aperture cavities of the punched carrier tape frame. These configured apertures of the PSA tape are centrally aligned and respectively located within the aperture cavities of the carrier tape frame.

Abstract: An adjuvant is described which comprises an iron compound in colloidal form as well as a pharmaceutical composition which comprises this adjuvant together with at least a protein and/or peptide and/or polysaccharide and/or a nucleic acid derived from a virus, bacterium and/or a parasite.The adjuvant according to the invention and the pharmaceutical composition comprising this adjuvant are suitable for prophylactic or therapeutic treatment of illnesses caused by various pathogens.

Abstract: A carrier tape which includes a punched tape with a plurality of aperture cavities, and a backing tape having a thin flexible gel material between a pair of strips of parallel pressure sensitive adhesive material. The flexible gel material covers all of the aperture cavities of the punched tape, so that singulated die and other components with a single flat surface can be placed on the surface of the flexible gel layer to hold the die or other component precisely in place, even during handling or shipping. The gel layer has high resistance to shear forces (movements in X, Y and theta) yet minor resistance to peel forces (removal in the Z-axis). The die is retained within an aperture cavity and it is adhered to the thin flexible gel layer such that the small component is unable to move in the X, Y or theta directions. The gel layer holds the die in place securely while the carrier tape is moving during processing and prevents fallout or dislocation of the die during high speed automated processing.

Abstract: The present invention utilizes multiple and split pressure sensitive adhesive (PSA) tape stratums for carrier tape packaging systems to receive, retain and release small components in automated assembly processing. A carrier tape includes many small apertures which extend through the thickness of the carrier tape. Each aperture is designed to carry a small component. The present invention utilizes a pair of parallel lengths of pressure sensitive tape which are separated by a gap to retain each component within its respective aperture.

Abstract: An improved apparatus incorporated in a cast metal frame of circular configuration to allow one frame to accommodate similar objects of slightly different sizes and retain them therein to prevent rotation of the object within the cast frame. Further improvements are designed in the retaining means which rigidly hold the object in cast frames of circular, rectangular and oval configurations while at the same time allowing the retaining means to be easily removed.

Abstract: An improved frame design for retaining a coin, medallion and other jewelry objects wherein a frame of one standard size can accommodate similarly shaped objects within a range of differing thicknesses. An improved shim which allows a standard size frame to accommodate similarly shaped objects whose perimeter dimensions are small enough so that the object can move inside the frame. An improved retaining ring which serves to impede the rotation of a circular object inside a cylindrical frame.

Abstract: A method of casting metal so that the finished casting will hold a precise dimension in certain critical areas in order to enable the finished casting to be used as a frame for objects such as coins and medallions which are die struck to precise dimensions. Means of and apparatus for rigidly maintaining the object inside the cast frame by inexpensive means which will not damage the object and which will allow the object to be easily removed from the frame if necessary.
