Abstract
The utility model discloses a kind of improvement braid cover plate, belong to leadframe package technical field.It improves on original braid cover plate basis, it comprises suction nozzle, for calibrating the plastic-sealed body braid cover plate of product space on suction nozzle, braid cover plate is axially made up of three sections of braid cover plates of different-diameter size along suction nozzle, wherein the braid cover plate diameter at two ends is identical, the diameter of interlude braid cover plate is greater than the diameter of two ends braid cover plate, interlude braid cover plate and two ends braid cover plate are installed interface and are oblique surface, two oblique surface chamfering angle sizes are identical, form positioning chamber between two oblique surfaces.Its advantage is: adopt plastic-sealed body to come calibration product position, product is made to carry out the position of calibration product on suction nozzle when entering braid by braid cover plate and then enter braid, greatly reduce product pin encounter carrier band and stick up the probability of pin, improve the quality of product, reduce client sticks up pin complaint and complaint to product.
Description
Technical field
The utility model relates to leadframe package technical field, is specially a kind of improvement braid cover plate.
Background technology
Lead frame is as the chip carrier of integrated circuit, it realizes the electrical connection of chip internal circuits exit and outer lead by means of bonding material (spun gold, aluminium wire, copper wire), form the key structure part of electric loop, it serves the function served as bridge be connected with outer lead, all needing in the semiconductor integrated block of the overwhelming majority to use lead frame, is basic material important in electronics and information industry.
Existing braid cover plate is larger, and due to the reason such as product design and material, non-calibrating position when braid place product presses down, the position of product on suction nozzle is rocked larger, and due to the limit deviation of the width dimensions of carrier band and the overall dimension of encapsulating products little, as fruit product some deviation a little when to enter, enter position place product pin in braid and be easy to encounter carrier band and cause and stick up pin, client easily causes rosin joint when upper plank, causes complaint and the complaint of client.
Utility model content
The utility model improves braid cover plate for the technical problem solved for providing a kind of, it designs braid cover plate according to the profile of product, plastic-sealed body is adopted to come the position of calibration product on suction nozzle, product is made to carry out the position of calibration product on suction nozzle when entering braid by braid cover plate and then enter braid, thus can farthest avoid product pin encounter carrier band and stick up pin, improve the quality of product.
The utility model technical solution problem adopts following technical scheme:
There is provided a kind of and improve braid cover plate, it improves on original braid cover plate basis, it comprises suction nozzle, for calibrating the plastic-sealed body braid cover plate of product space on suction nozzle, it is characterized in that: described braid cover plate is axially made up of three sections of braid cover plates of different-diameter size along suction nozzle, wherein the braid cover plate diameter at two ends is identical, and the diameter of interlude braid cover plate is greater than the diameter of two ends braid cover plate.
As preferred embodiment, described interlude braid cover plate and two ends braid cover plate are installed interface and are oblique surface, and two oblique surface chamfering angle sizes are identical, form positioning chamber between two described oblique surfaces.
The utility model compared with prior art, its beneficial effect is: it designs braid cover plate according to the profile of product, plastic-sealed body is adopted to come calibration product position, product is made to carry out the position of calibration product on suction nozzle when entering braid by braid cover plate and then enter braid, greatly reduce product pin encounter carrier band and stick up the probability of pin, improve the quality of product, reduce client sticks up pin complaint and complaint to product.
Accompanying drawing explanation
Fig. 1 is the structural representation of original braid cover plate described in the utility model.
Fig. 2 is the structural representation of improvement braid cover plate described in the utility model.
Number in the figure: 1 is braid cover plate, and 2 is suction nozzle, and 11 is two ends braid cover plate, and 12 is interlude braid cover plate, and 13 is positioning chamber.
Embodiment
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
A kind of improvement braid cover plate, it improves on original braid cover plate basis, it comprises suction nozzle 2, for calibrating the plastic-sealed body braid cover plate 1 of product space on suction nozzle 2, braid cover plate 1 is axially made up of three sections of braid cover plates of different-diameter size along suction nozzle 2, wherein braid cover plate 11 diameter at two ends is identical, and the diameter of interlude braid cover plate 12 is greater than the diameter of two ends braid cover plate 11.
Interlude braid cover plate 12 and two ends braid cover plate 11 are installed interface and are oblique surface, and two oblique surface chamfering angle sizes are identical, form positioning chamber 13 between two oblique surfaces.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
