DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a tape having a series of recesses along its length for storage of electronic components.
An electronic flatpack is a relatively thin package containing numerous electronic components and which is rectilinear in shape (being either square or rectangular) provided on all four side faces with protruding, cranked or gull wing, connector pins, which are generally made of fine closely spaced wires for connection of the components to a printed circuit. The connector pins are numerous to convey signals to and from the numerous components contained within the flatpack and as the packing density of these components increases so the gauge of the pins and the spacing of the pins decreases so that in flatpacks which are currently available the pins are filigree in nature and highly vulnerable to damage or distortion prior to being secured to the printed circuit.
Conventionally, before assembly on a printed circuit these flatpacks are stored in trays of about thirty in respective recesses and the trays are stacked one on top of another. This does not provide for adequate security or protection against damage to the connector pins since the trays may be upset leading to a spillage of flatpacks. The flatpacks are relatively free to move within their respective recesses which leads to damaged pins during movement of the trays and the trays are open at the top leading to contamination of the flatpacks by dust and dirt.
Removal of the flatpack from the tray recess is often an automatic process in which a pick-up device such as a suction nozzle is placed in contact with and lifts the flatpack. Often, however, the lift is not vertical and the protruding cranked connector pins are deformed or broken off due to contact with the walls or floor of the recess making the flatpack difficult or impossible to fit to the printed circuit, or inoperative.
It is an object of the present invention to obviate or substantially mitigate the aforementioned problems.
According to one aspect of the present invention there is provided a tape for storage of electronic components, said tape comprising a series of recesses along its length which have been depressed out of the original plane of the tape and whose openings lie in the original plane of the tape, each recess comprising a floor and walls, the floor being disposed at a predetermined depth from the original plane of the tape, the series of recesses being spaced inwardly from the edges of the tape to define outer marginal edge portions on the tape characterised in that along each tape marginal edge portion is provided a row of sprocket holes and, inwardly of said holes, a continuous tape surface for reception of a line of adhesive releasably to secure a length of cover film over the series of recesses, and in that a portion of the floor of each recess is deformed to define within the recess an upstand extending in a generally rectilinear fashion around the floor, the upstand being profiled in cross-section to define a generally rectilinear support surface disposed at a first clearance from said floor and a ridge at the peripherally outer boundary of the support surface, the top of the ridge being disposed at a second clearance from said floor, the second clearance being greater than the first clearance, and the ridge being spaced by a third clearance from the adjacent wall of said recess, the arrangement being such that in use each recess is adapted to store an electronic flatpack having protruding connector pins, the body of the flatpack being carried by the support surface and held against the support surface by the cover film, and being restricted in lateral movements by the ridge, with the cranked connector pins being disposed over said ridge and extending into said third clearance.
Preferably said recess is square in outline and the upstand has four separated portions respectively aligned with the adjacent wall of said recess.
Preferably also said tape is made of a semi-rigid material so that the tape portions separating adjacent recesses are capable of
