Abstract
The utility model provides a high-temperature-resistant rubber suction nozzle, wherein a surface of the rubber suction nozzle has granular projections; the rubber suction nozzle is provided with a groove and vacuum holes; the groove and the vacuum holes are connected; the groove is disposed in the center of the rubber suction nozzle; and the granular projections are positioned at edges of the rubber suction nozzle. Compared with the prior art, according to the provided high-temperature-resistant rubber suction nozzle, the granular projections are utilized, a contact area of the rubber suction nozzle and a high-temperature chip is reduced, use period and service life of the suction nozzle are prolonged, and production cost is reduced.
Description
Technical field
The utility model relates to the semiconductor die package field, relates in particular to a kind of encapsulation high-temperature resistant rubber suction nozzle.
Background technology
In chip encapsulating manufacturing procedure, the high-temperature resistant rubber suction nozzle holds the chips wire road surface, deliver to the high temperature hot pressing head after upset, and the thermal head temperature is more than 400 ℃, the rubber suction nozzle is also smooth mostly, therefore in the course of the work, rubber suction nozzle surface all contacts with chip, after frequent contact of long period, rubber suction nozzle surface is subjected to temperatures involved to have the existing picture such as melting, be full of cracks, can pollute the chip circuit, and absorption chip stability descends also, the problems such as the generation suction is askew, drop, the suction nozzle that need to more renew.
Therefore be necessary to provide a kind of new high-temperature resistant rubber suction nozzle to solve the problems referred to above.
The utility model content
The utility model relates to a kind of improved high-temperature resistant rubber suction nozzle.
For reaching above-mentioned utility model purpose, the utility model provides a kind of high-temperature resistant rubber suction nozzle, and described rubber suction nozzle surface has the graininess projection, and described rubber suction nozzle is provided with groove and is connected with vacuum hole.
As further improvement of the utility model, described groove is located at described rubber suction nozzle center, and described graininess projection is positioned at described groove periphery.
As further improvement of the utility model, described rubber suction nozzle is rectangle.
As further improvement of the utility model, described vacuum hole is circular hole or square hole.
As further improvement of the utility model, described vacuum hole quantity is a plurality of.
Compared with prior art, high temperature resistant suction nozzle provided by the utility model utilizes the graininess projection, has reduced the contact area of rubber suction nozzle and high temperature chip, has extended service time and the life-span of suction nozzle, has reduced production cost.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the profile of high-temperature resistant rubber suction nozzle one embodiment of the utility model;
Fig. 2 is the upward view of high-temperature resistant rubber suction nozzle one embodiment of the utility model;
Fig. 3 is the upward view of another embodiment of high-temperature resistant rubber suction nozzle of the utility model.
Wherein, Reference numeral is:
The rubber suction nozzle, 1; The graininess projection, 2; Groove, 3; Vacuum hole, 4; The graininess projection, 5; Groove, 6; The rubber suction nozzle, 7; Vacuum hole, 8.
Embodiment
Below with reference to each embodiment shown in the drawings, the utility model is described in detail.But these embodiment do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiment, method or function all is included in protection range of the present utility model.
Join illustrated in figures 1 and 2ly, be the high-temperature resistant rubber suction nozzle 1 of the utility model one embodiment, rubber suction nozzle 1 is designed to rectangle, be provided with graininess projection 2 on its surface, be provided with groove 3 in the middle of rubber suction nozzle 1, groove 3 is connected with vacuum hole 4, and vacuum hole 4 is circular hole or square hole.When 1 work of rubber suction nozzle, effect by 4 pairs of grooves 3 of vacuum hole, form pull of vacuum, chip to be packaged is picked up, contact with rubber suction nozzle 1, due to the existence of graininess projection 2, make the contact area of high temperature chip and rubber suction nozzle 1 reduce, thereby reduce distortion and improve pollution situation, extending the useful life of rubber suction nozzle 1.
As shown in Figure 3, in another embodiment of the utility model, in order to guarantee rubber suction nozzle 7, enough pulls of vacuum are arranged, be designed to 2 vacuum holes 8 in groove 6, certainly, also more vacuum hole can be set, form fast enough large absorption affinity, graininess projection 5 is distributed in the edge of rubber suction nozzle 7.
Described graininess projection can be by roughening treatment, or utilizes mould to realize, this is those of ordinary skills' technology known, and therefore not to repeat here.
High-temperature resistant rubber suction nozzle provided by the utility model, surperficial by special roughening treatment to the rubber suction nozzle, utilize the graininess projection, reduced the contact area of rubber suction nozzle and high temperature chip, extend service time and the life-span of suction nozzle, reduced production cost.
Be to be understood that, although this specification is described according to execution mode, but be not that each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, technical scheme in each execution mode also can through appropriate combination, form other execution modes that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description is only illustrating for feasibility execution mode of the present utility model; they are not to limit protection range of the present utility model, all disengaging within equivalent execution mode that the utility model skill spirit does or change all should be included in protection range of the present utility model.
