Abstract
The utility model discloses a dispensing device with a supporting rod. The dispensing device consists of a dispensing rod and a dispensing needle in sequence from top to bottom, wherein the dispensing needle is in contact with a lead framework; the supporting rod is arranged at one end, which is connected with the dispensing needle, of the dispensing rod; the supporting rod is located on the both sides of the dispensing needle; the supporting rod is 0.15mm longer than the dispensing needle in a vertical direction. The dispensing device with the supporting rod has the advantages of simple structure, convenience in manufacturing, low cost and facilitating of popularization; meanwhile, the technical difficult problem that the lead framework cannot keep horizontal due to various reasons in a dispensing process in prior art, so that a dispensed forming face is irregular after the dispensing process can be effectively solved. Therefore, the good foundation can be provided for the follow-up package process.
Description
Technical field
The utility model semiconductor packages field, is specifically related to a kind of point glue equipment with support bar.
Background technology
The die bonder that semiconductor chip is attached on lead frame or mainboard is to be generally stored in the storage sebific duct of Glue dripping head in connection with material (glue), utilize air pressure to extrude and be applied on lead frame in connection with material (glue), then place the method for semiconductor chip in the above, semiconductor chip is attached on lead frame.Along with the development of technology, the size of the semiconductor chip adhering to by die bonder like this presents more and more less trend.
Because size is more and more less, when carrying out a some glue operation, because can making some lead frame, a variety of causes can not maintain an equal level with horizontal direction, further cause that to put gum forming face after the inhomogeneous or appearance point glue of a glue time point glue irregular, this can bring a lot of negative shadow problems for semi-conductive follow-up packaging technology, affects follow-up semiconductor packages.
In prior art point glue equipment when work as shown in Figure 1, point glue equipment consists of a glue bar 11, some plastic pin 12 from top to bottom successively, described some plastic pin 12 contact lead-wire frameworks 13, because lead frame 13 can not maintain an equal level with horizontal plane, can cause that to put gum forming face after the inhomogeneous or appearance point glue of a glue time point glue 14 irregular.
In Chinese invention patent description CN102476089A, disclose a kind of dispensing apparatus for chip welding machine, described dispensing apparatus for chip welding machine comprises: base, container member, rotary module, extruded member, supporting member and some rubber moulding piece.Wherein container member has outer member and inner member, the profile of outer member is cylindrical, and be formed with box thread portion at medial surface, inner member has the male screw portion of being combined with screw fashion with outer member box thread portion on lateral surface, and there is dipping face, for viscose coating and above it.Extruded member has the press section staggered relatively with dipping face.Although described some glue supervisor brain can guarantee the glue amount of both having fixed a point, make bothering very much and can not effectively guarantee that lead frame is in horizontal direction when welding.
Utility model content
For solve existing point glue equipment structure too complicated and solve lead frame when the glue can be in horizontal direction, the quality of guarantee point glue, the utility model provides a kind of point glue equipment with support bar.
Described a kind of point glue equipment with support bar, consists of a glue bar, some plastic pin from top to bottom successively, described some plastic pin contact lead-wire framework, and described some glue bar tie point plastic pin one end is provided with support bar, and described support bar is positioned at a plastic pin both sides.
Wherein, in order better to flatten lead frame, described support bar vertical-direction length is greater than a plastic pin vertical-direction length.
Preferably, described support bar Length Ratio point plastic pin length is large 0.15 millimeter in vertical direction
The beneficial effects of the utility model are that it is simple in structure, and it is convenient to make, and cost is low, is beneficial to popularization; Simultaneously the beneficial effects of the utility model are that it has effectively solved in prior art after causing the inhomogeneous or appearance point glue of a glue in the time of can not maintaining an equal level horizontal plane due to a variety of causes lead frame when glue and puts the irregular technical barrier of gum forming face, for follow-up packaging technology provides good basis.
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 prior art structural representation;
Fig. 2 is structural representation of the present utility model;
Schematic diagram when Fig. 3 is the utility model point glue.
Point glue bar: 11,21; Point plastic pin: 12,22; Lead frame: 13,23;
Support bar: 24.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
With reference to figure 2 and Fig. 3, the described point glue equipment with support bar is when glue, because point glue equipment contains large 0.15 millimeter in vertical direction of support bar 24 and described support bar 24 Length Ratio point plastic pin 22 length, support bar 24 just can be pressed lead frame 23 to cause horizontal parallel direction when fitting tightly with lead frame 23 so, because described lead frame 23 maintains an equal level in the horizontal direction, so it is even that point glue equipment can be realized a glue, produces a desired effect.
Known by above description, the beneficial effects of the utility model are that it is simple in structure, and it is convenient to make, and cost is low, is beneficial to popularization; Simultaneously the beneficial effects of the utility model are that it has effectively solved in prior art after causing the inhomogeneous or appearance point glue of a glue in the time of can not maintaining an equal level horizontal plane due to a variety of causes lead frame when glue and puts the irregular technical barrier of gum forming face, for follow-up packaging technology provides good basis.
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.
