Abstract
The utility model discloses a cleanser coating support in electronic element encapsulation. The cleanser coating support is characterized by comprising a bottom plate, wherein a coating component which can adsorb cleanser and effuse the cleanser under pressure is arranged on the bottom plate. When the cleanser coating support is used, an operator does not need to hold a brush in hand for painting so that labor intensity is low and efficiency is high. At the time of coating, the cleanser can be coated on the lower surface of a pin without the need of turning over a mold and an electronic element so that the labor intensity is further lowered, and the labor efficiency is further improved. A support column is arranged on the bottom plate, a fixture is placed on the support column at the coating time, and the support column supports the fixture so that not only can the labor intensity be lowered, but also accurate positioning can be realized, and bending of the pin due to over large pressure is avoided. A limiting column is arranged to enable the fixture to be accurately placed at a position where the cleanser can be coated, and therefore coating work is simpler and more convenient. By utilization of the cleanser coating support, the time needed for coating the electronic element in a set of fixture is only one tenth that of an original painting method, and the efficiency can be improved by more than ten times.
Description
Technical field
The utility model relates to the cleaning agent drug delivery medical device in the electronic package.
Background technology
Be illustrated in figure 1 as a kind of electronic component structure schematic diagram.Fig. 2 is the structure chart after the electronic package.As shown in Figure 1 and Figure 2, during electronic component 30 encapsulation, two pins 33 are welded as a whole with chip 31 by the weld tabs 32 of end respectively, and then utilize resin material that chip 31 and weld tabs 32 are encapsulated in the resin material 34.Adopt in the electronic package operation of resin material encapsulation, adopt encapsulating mould to realize.Electronic component to be packaged is positioned in the encapsulating mould, injects encapsulating mould after the resin material fusing, and encapsulation is finished in parcel chip 31 and weld tabs 32 rear curing after the depanning.
The usage quantity of electronic component is huge, all needs to use a lot of electronic components in each integrated circuit.Therefore, the production scale of electronic component is very large.This just requires can encapsulate simultaneously a plurality of electronic components in the per pass operation.View when being illustrated in figure 3 as a kind of a plurality of electronic package, 5 electronic components are arranged and are neatly put into respectively an encapsulation die cavity, and resin material flows into successively and respectively encapsulates encapsulation in the die cavity.Because each electronic component is individual packages respectively, so a resin material total runner that circulates need to be set, through this total runner, resin material injects respectively respectively and encapsulates in the die cavity.Because total runner is set, after encapsulation was finished, the resin material that is retained in total runner solidified.As shown in Figure 3, because total runner need to be arranged on the below of at least one pin 33, form a cull bar 35 after the resin material in therefore total runner solidifies, and this cull bar 35 sticks on row's electronic component pin 33.
In order to remove easily cull bar 35, cleaning agent is coated at the position that need to adhere to easily cull bar 35 on pin 33.Cleaning agent can prevent that the cull bar from sticking on the pin 33, even it sticks on the pin 33, also can remove at an easy rate.In the prior art, the brushing working procedure of cleaning agent is loaded down with trivial details, needs operating personnel to take brush to dip in cleaning agent with hand and brushes at pin 33, and labour intensity is large.Because the cull bar sticks to pin 33 belows, therefore need to will brush behind the electronic element overturning that arrange, after finishing, brushing turns back again, so that cleaning agent is positioned at the lower surface of pin 33.Often turning over electronic components has increased labour intensity, has prolonged the operating time.Especially electronic component is and is arranged in first on the anchor clamps, puts into mould again and encapsulates.Anchor clamps adopt stainless steel and other metal materials to make, and weight is heavier.Can only come turning over electronic components by turnover fixture, labour intensity is very large.When using brush to brush, because electronic component 30 volumes are little, pin 33 Length Ratios are shorter, therefore can be easy to cleaning agent is brushed on weld tabs even chip, affect packaging effect, operation easier is large.

First purpose of the present utility model is in order to overcome deficiency of the prior art, the cleaning agent drug delivery medical device in the electronic package of on the electronic component pin brushing cleaning agent of providing convenience.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Cleaning agent drug delivery medical device in the electronic package is characterized in that, comprises base plate, and described base plate is provided with the application member that can adsorb cleaning agent and ooze out cleaning agent when pressurized.
Preferably, described base plate is provided with support member, and described application member is arranged on the support member, and protrudes from the upper surface of support member.
Preferably, described support member is boss.
Preferably, described boss is provided with storage tank, and described application member is arranged in the storage tank and protrudes from the support member upper surface.
Preferably, the cell wall of described storage tank is provided with the fixed bar that runs through described storage tank and application member.
Preferably, described boss is shaped as cuboid.
Preferably, also comprise limited post, described limited post is around described application member setting.
Preferably, also comprise pillar, described pillar is arranged on the base plate and centers on described application member setting.
Preferably, described application member is sponge, cotton, fiber or filter paper.
Cleaning agent drug delivery medical device in the electronic package in the utility model, the adsorbable cleaning agent of application member that arranges, when needing to apply cleaning agent, electronic component is placed on the application member top makes pin compressing application member, the cleaning agent of application member absorption oozes out and sticks on the pin, finishes coating work.Therefore, when using the utility model, need not to use hand-held brush brushing by operating personnel again, labour intensity is low, and efficient is high.During brushing, directly electronic component is placed on the application member and gets final product, need not turnover fixture and electronic component again and cleaning agent can be coated in the pin lower surface, labour intensity further reduces, and efficiency further improves.Be provided with pillar on the base plate, during coating anchor clamps be placed on the pillar, by the shore supports anchor clamps, both can reduce labour intensity, the excessive and bending of pin pressure is avoided in accurate location.Limited post is set, can makes anchor clamps accurately be placed on the position that can apply, coating work is easier.Use the cleaning agent drug delivery medical device in the electronic package in the utility model, the electronic component required time that applies in the sub-folder tool only is 1/10th of former brushing method, and efficient can improve more than ten times.
