Abstract: This invention aims to provide a package of a terminal series strip which can make full use of the last terminal metal fixture 11 on a leading end of a terminal series strip 10 wound around a bobbin 14 as a package. The leading end of the terminal series strip 10 is connected through an auxiliary strap 17 to the bobbin 14. Even if the leading end is paid out from the bobbin 14 after the terminal series strip 10 has been almost paid out from the bobbin 14, the auxiliary strap 17 is maintained to be connected to the bobbin 14. Thus, the terminal series strip 10 can be maintained to be hung between the bobbin 14 and a crimping apparatus until the last terminal metal fixture 11 on the terminal series strip 10 is press-worked.
Abstract: In order to properly hold a number of miniaturized electronic component chips so that processing such as formation of external electrodes can be efficiently performed, a holder having an adhesive face to be stuck to first end surfaces of a number of electronic component chips for holding the electronic component chips is employed. The number of electronic component chips being held by the holder are dipped in electrode paste, so that external electrodes are formed on second end surfaces thereof. Then, an adhesive face of another holder having stronger adhesion than the adhesive face of the first holder is stuck to the electronic component chips, whereby the number of electronic component chips are simultaneously transferred to this holder. The first end surfaces are then also dipped in electrode paste to form external electrodes thereon.
Abstract: A flexible carrier tape for storage and delivery of electronic components by an advancement mechanism comprises: (a) a strip portion having a top surface, a bottom surface opposite the top surface, and means for engagingly receiving the advancement mechanism; and (b) a plurality of aligned pockets for carrying the electronic components. The pockets are spaced along the strip portion and open through the top surface. The means for engagingly receiving the advancement mechanism comprises a plurality of hollow protuberances that are spaced equally along the strip portion, open through the strip portion, and extend outwardly from the strip portion. The protuberances are adapted to receive the advancement mechanism within the hollow portion. Methods for manufacturing such carrier tapes are also disclosed.

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: A lifting mechanism is arranged between a cartridge main body and a reel support member. With the cartridge main body set in a parts mounter, the lifting mechanism allows the reel support member to be supported by the cartridge main body so that the reel support member can be pivoted upward at a predetermined pivoting angle (set position PA.fwdarw.bar code read position PB). While cartridges are kept placed in the parts mounter, a parts supply reel attached to a given cartridge is made to project from other reels. This enables a bar code reader to read the parts code of a label adhered on one side surface of that reel.
Abstract: A transparent static dissipative adhesive tape is disclosed. The tape comprises a transparent polymer substrate having opposed first and second surfaces, a transparent static dissipative coating on the first surface of the substrate, and a transparent static dissipative adhesive coating on the second surface of the substrate. The adhesive coating comprises a transparent conductive layer on the second surface formed of conductive particles in a polymer matrix, and a transparent adhesive layer without any conductive particles over the conductive layer. The exposed surface of the adhesive layer exhibits conductivity substantially the same as the conductivity of the underlying conductive layer.

Abstract: A BGA carrier for storing and shipping of BGA packages in a side-by-side arrangement adapted for dispensing of the same in a one-by-one fashion under gravity includes a flat elongated tubular body member (22), a lower end plug member (24), and an upper end plug member (26). The tubular body member has a first end and a second end. The tubular body member has a bore of a rectangular cross-section extending therethrough between the first end and the second end. The tubular body member includes a flat top wall portion (29), a flat bottom wall portion (30), and a pair of vertically extending side walls (32, 34) all formed integrally together. Opposed overhanging slot means (36) are formed in the pair of vertically extending side walls for supporting only two side edges of a plurality of BGA packages (12) so that top and bottom surfaces thereof are suspended freely between the top and bottom wall portions of the tubular body member.
