Abstract
The utility model provides a novel dispensing head structure which comprises a dispensing head, a dispensing needle is connected below the dispensing head, a glue barrier wall is arranged around the dispensing needle, the upper end of the glue barrier wall is connected with the dispensing head, the height of the glue barrier wall is greater than that of the dispensing needle, and the glue barrier wall is a cylinder surrounding the dispensing needle. According to the novel dispensing head structure provided by the utility model, the phenomenon that the combined material is easy to overflow to exceed the predetermined coverage range so as to influence the subsequent package process when the existing soling flake is in dispensing job, and the quality of the soldering flake dispensing is improved.
Description
Technical field
The utility model relates to semiconductor packages field, is specifically related to a kind of novel spot gluing header structure.
Background technology
When existing semiconductor packages needs the operation of weld tabs point glue, its Glue dripping head point glue operation is as Fig. 1, comprise Glue dripping head 10, it is in conjunction with material that 10 times connections of described Glue dripping head have a plastic pin 11,12, and 13 is lead frame, during normal work, described combination material 12 out arrives described lead frame 13 through some plastic pins from Glue dripping head 10, due to the not stationarity in conjunction with material, can cause overflowing area in conjunction with material 12 excessive and affect weld tabs and follow-up encapsulation process.
Application number is that 200820146882.2 Chinese patent discloses the utility model patent that name is called " Glue dripping head ", it comprises syringe needle and rubber-storing cylinder, described rubber-storing cylinder comprises a cylindrical sleeve and the inverted conical sleeve being connected thereunder, and the top of the sidewall of the gum outlet of its lower end is provided with a vee; In its patent, due to the not stationarity of glue, in gluing process, easily overflow glue and affect a glue, thereby make troubles for a some glue process.
Utility model content
The purpose of this utility model is to provide a kind of novel spot gluing header structure, while solving existing weld tabs point glue operation, exceeds predetermined coverage, thereby affect the phenomenon of follow-up packaging technology in conjunction with material easily overflows, and improves the quality of weld tabs point glue.
In order to overcome the above problems, the utility model provides a kind of novel spot gluing structure, comprises Glue dripping head, under described Glue dripping head, connect and have a plastic pin, improvements of the present utility model are, the surrounding of described some plastic pin is provided with a gear Jiao Bi, and the upper end of described gear Jiao Bi is connected in described Glue dripping head.
Further, the height of described gear Jiao Bi is greater than the height of described some plastic pin.
Further, described gear Jiao Bi is the cylinder around described some plastic pin.
The utility model provides a kind of novel spot gluing structure, by connect a cylindrical gear Jiao Bi outside a plastic pin, while having solved existing weld tabs point glue operation, in conjunction with easily overflowing, material exceeds predetermined coverage, thereby affect the phenomenon of follow-up packaging technology, improved the efficiency of welding quality and weld tabs thereof simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of existing weld tabs point glue operation;
The structural representation of a kind of novel spot gluing header structure that Fig. 2 provides for the utility model;
The structural representation of the weld tabs point glue operation that Fig. 3 provides for the utility model.
The specific embodiment
A kind of novel spot gluing header structure that the utility model provides, while having solved existing weld tabs point glue operation, exceeds predetermined coverage in conjunction with material easily overflows, thereby affects the phenomenon of follow-up packaging technology, has improved the quality of weld tabs point glue.
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described, obviously, described is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
Referring to Fig. 2, a kind of novel spot gluing header structure, comprise Glue dripping head 1, described Glue dripping head connects for 1 time a plastic pin 2, the surrounding of described some plastic pin 2 is provided with a gear glue wall 3, and the upper end of described gear glue wall 3 is connected in described Glue dripping head 1, and the height of described gear glue wall 3 is greater than the height of described some plastic pin 2, described gear glue wall 3 is the cylinder around described some plastic pin, plays the effect of overflowing in conjunction with material of preventing.
Referring to Fig. 3, during normal work, in conjunction with material 4, from described some plastic pin of the interior process of Glue dripping head 12, arrive described lead frame 5, owing to thering is not stationarity in conjunction with material, so easily overflow predetermined coverage when weld tabs point glue, thereby the glue operation of impact point and follow-up packaging process, thus in the periphery of a plastic pin around a columniform gear glue wall 3, thereby well solved the phenomenon of overflowing in conjunction with material in existing weld tabs point glue process.
Known by above description, the utility model provides a kind of novel spot gluing structure, by connect a cylindrical gear Jiao Bi outside a plastic pin, while having solved existing weld tabs point glue operation, in conjunction with easily overflowing, material exceeds predetermined coverage, thereby affect the phenomenon of follow-up packaging technology, improved the efficiency of welding quality and weld tabs thereof simultaneously.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
Claims (3)
