Description
The present invention relates to a resin-sealing apparatus (resin mold apparatus), and more particularly to a resin-sealing apparatus (resin mold apparatus) which uses a granular resin (referred to as granular resin in the present application) To an effective technique applied to a sealing device.
Japanese Patent Application Laid-Open No. 2009-234000 (Patent Document 1) discloses a technique capable of supplying a granular resin to a resin supply source. This technique is to supply a granular resin using a shooter that extends in the vertical direction and a diffuser that is located in the shooter and diffuses the resin (diffusion method).
One of the resin-sealing apparatuses provided with a resin supply unit is a system in which a granular resin is fed and supplied to one surface of a work (supplied portion) in a resin supply unit and the work is conveyed to the press unit, And a resin sealing portion is formed on the work.
As one method of supplying the resin to the resin supplying portion, there is a method of opening the shutter to open the granular resin held in a cylindrical holder whose bottom portion is closed by a shutter, and feeding the granular resin to the work (open method). Another resin supplying method is a method in which a resin-loaded portion or a table on which a work is mounted is moved in the X and Y directions by feeding a granular resin through a resin dropping portion to the work, A granule resin is fed and fed (writing method). There is also a method of manually feeding the granular resin to the work.
Even if the granular resin is fed by dropping on one side of the work so as to be evenly spread by using an open system, a lighting system, a diffusion system, or the like, unevenness is actually formed on the deposition surface because of the discharge of the granular resin. Specifically, for example, even if the granular resin is supplied in a uniform thickness to the workpiece on which the electronic components are mounted in a matrix form, irregularities arise in the surface of the supplied resin due to the arrangement of the electronic components. When the resin-fed workpiece is compression-molded as described above, an air pocket is generated between the mold and the workpiece, and air can not be sufficiently discharged. As a result, molding defects such as unfilled You can also think of.
An object of the present invention is to provide a technique capable of reducing defective molding of a molded product. These and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.
Outline of representative ones of inventions disclosed in the present application will be briefly described as follows.
A resin-sealing apparatus according to an embodiment of the present invention is provided with a resin supply portion for supplying and supplying a granular resin to a work, and a press portion having a pair of molds for clamping and hardening the work supplied with the granular resin . Wherein the resin supply portion includes a resin dropping portion for dropping the granular resin into the workpiece, a workpiece mounting portion on which the workpiece is mounted and disposed immediately below the resin dropping portion, and at least one of the resin dropping portion and the workpiece mounting portion is moved And a drive mechanism for driving the motor.
Here, the resin supply section may include: a first storage section for storing the granular resin; a second storage section for temporarily storing the granular resin from the first storage section in a smaller size than the first storage section; And a weighing machine mounted on the workpiece mounting part for measuring the amount of the granular resin to be discharged in a state in which the workpiece is mounted on the workpiece mounting part. The resin supply portion is configured such that the first storage portion is fixed and the resin discharge portion is moved by the drive mechanism together with the second storage portion and the workpiece mount portion is fixed.
According to this, the movable portion including the resin drop portion can be made lighter and smaller, and the movement of the resin drop portion is smooth. In addition, it is possible to correct an error between a delivery amount measured by the weighing scale and a delivery scheduled amount. These are connected to reducing defective molding such as uncharged.
Alternatively, the resin supply portion is configured such that the resin receiving portion is fixed, and the workpiece mounting portion is moved by the drive mechanism.
According to this, it is possible to accurately supply the granular resin to the predetermined position in the horizontal plane of the work W at a predetermined position. This leads to reduction of defective molding such as non-filling.
Further, in the resin-sealing apparatus, the base resin portion is formed by lighting by continuously blowing the granular resin onto the work from the resin supply portion while moving the workpiece mount portion relative to the resin supply portion by the drive mechanism, The resin is supplied to the central portion of the base resin portion so as to form a middle (high) resin portion having a height higher than that of the base resin portion.
According to this, even when the surface of the base resin part has irregularities, the resin melted from the used resin part can flow on the surface of the base resin part to fill the irregularities. Therefore, defective molding such as unfilled can be reduced.
The resin-sealing apparatus further includes a preheating section which is provided in a conveyance path of the work from the resin supply section to the press section and preheats the workpiece supplied with the granular resin to a temperature lower than the molding temperature.
According to this, air between the granular resin can be reduced by the melted resin. That is, it is possible to prevent air from being entrained inside the resin sealing portion at the time of molding. This leads to reduction of defective molding such as non-filling.
And a cooling section which is provided in the conveyance path of the work from the preheating section to the press section and cools the preheated work.
According to this, even when the granular resin is heated by the preheating portion, shortening of the gel time until molding can be suppressed. That is, the fluidity of the resin can be ensured at the time of molding. Therefore, even if there is unevenness on the surface of the basic resin part, the resin melted from the used resin part flows over the surface of the base resin part to fill the unevenness. This can reduce defective molding such as non-filling.
Effects obtained by the representative ones of the inventions disclosed in the present application will be briefly described as follows. According to the resin sealing apparatus according to the embodiment of the present invention, defective molding of a molded product can be reduced.

While the present invention has been described in detail with reference to the embodiment thereof, it is needless to say that the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the present invention.
For example, in the first embodiment, the case where the first and second resin delivering operations are performed by the lighting method using the resin delivering section has been described. However, the present invention is not limited thereto, and the first and second resin discharging operations may be performed by an opening method using a holder and a shutter, or a diffusion method using a shooter and a diffusion body. That is, in the resin supplying section, if the base resin section made of the granular resin is formed on the workpiece by the first resin feeding and the used resin section made of the granular resin can be formed on the base resin section by the second resin delivery , The method of resin release is not considered. Therefore, the first and second resin deliveries may be combined with a lighting method, an open method, and a diffusion method.
Even in such a case, defective molding of the molded article can be reduced in the same way. However, in the case of using the diffusion method or the open method, two sets of members such as a shooter and a holder are required to match the first and second resin dropping areas (that is, the area of the basic resin part and the area of the used resin part) do. In this respect, in the lighting method, even when the first and second resin discharging operations are performed, one resin discharging portion can be used, so that the number of components of the resin sealing apparatus (resin supplying portion) can be suppressed.
For example, in the first embodiment, the second resin discharge for forming the used resin portion is applied to one portion (central portion) of the portion to be fed with respect to the portion to be fed (workpiece) As shown in Fig. However, the present invention is not limited thereto, and the second resin may be discharged at a plurality of locations (for example, at two locations in the longitudinal direction of the portion to be fed) with respect to a rectangular work in plan view.
It is conceivable that the resin may not even reach the corner of the portion to be fed at the time of molding even if the second feeding of the resin is performed at one place of the central portion in a rectangular shape (in particular, a monolithic shape) viewed from the plane. On the other hand, by performing the second resin discharge at a plurality of locations, the resin can be evenly distributed from the top to the corner of the rectangular-shaped portion to be fed in plan view. Therefore, defective molding of a molded product such as unfilled can be reduced.
For example, in the first embodiment, the case where the shape viewed from the plane of the portion to be fed (work) has a rectangular shape has been described. However, the present invention is not limited to this, and may be a polygonal shape including a rectangular shape as viewed from a plane, or a circular shape. Even if a part to be fed is different in shape from a plane, if the first resin part is formed by the first resin feeding and the second resin part is formed by the second resin feeding, the defective molding of the molded article can be reduced likewise .
For example, in the first embodiment, a case where a substrate on which an electronic component is mounted is used as a part to be supplied (work). However, the present invention is not limited thereto, and a wafer, a carrier stage, a single-roll type film or a roll-type film may be applied as a fed portion. Even if the object to be supplied is different, if the first resin discharge is performed to form the basic resin portion and the second resin discharge is performed to form the second resin portion, the defective molding of the molded article can be similarly reduced.
For example, in the first embodiment, all of the electronic components on the heat-resistant side among the plurality of electronic components mounted in the form of a matrix on the substrate are covered with the granular resin, and the electronic components on the outside- The case of covering with the resin has been described. The present invention is not limited to this, and all the electronic parts on the outside heat side may be covered with the granular resin. This is because all the electronic parts are finally covered with the granular resin as a molded product.
For example, in the first embodiment, the case where the preheating section and the cooling section are provided in the preliminary processing section has been described. The present invention is not limited to this, and a cooling unit may not be provided in the preliminary processing unit. Thus, by preheating the work, it is possible to reduce the temperature at which the temperature should be raised to the molding temperature when the resin sealing portion is formed by heating and curing the granular resin in the cavity of the press portion. Further, by preheating the work, the whole work is heated, so that heat conduction is easy at the time of molding. Therefore, in the processing performed by the resin-sealing apparatus, the processing time by the press section that takes the longest time can be shortened, and the manufacturing cost of the molded article can be reduced.
For example, various types of patterns as shown in Figs. 23 (a) to 23 (f) can be considered as the lighting for discharging the granular resin from the resin discharge portion into the work surface. Figs. 23 (a) to 23 (c) show a pattern for a rectangular work in plan view, and Figs. 23 (d) to 23 (f) show patterns for circular work in plan view. 23 (a) and 23 (d) are patterns obtained by repeating one-directional scanning and scanning the entire surface. 23 (b) and 23 (e) are patterns in which the entire surface is scanned so as to concentrically form a scan similar to the work shape at the center of the work. 23 (c) and 23 (f) are patterns obtained by scanning the entire surface so as to form a whirl with the center of the work as the center so as to conform to the work shape.
23 (b), 23 (c), 23 (e), and 23 (f), when it is desired to uniformly supply a predetermined amount of the granular resin into the work surface, for example, The granular resin may be supplied to the outer peripheral portion at a constant delivery rate and the constant scanning rate and the granular resin may be supplied at the central portion by adjusting the delivery amount and the scanning speed with respect to the central portion. 23 (b), 23 (c), 23 (e), and 23 (f), in a case where it is desired to supply a used resin portion in the central portion of the work, The granular resin may be supplied to the outer peripheral portion at a constant delivery rate and at a constant scanning rate and the granular resin may be supplied at the central portion by adjusting the delivery amount and the scanning speed with respect to the central portion.
For example, as a work to be applied to the resin-sealing apparatus according to the present invention, various kinds of work (shown by broken lines shows an outer shape after sealing) as shown in Figs. 24 (a) to 24 (g) can be considered. 24 (a) is a work in which a plurality of bumps are mounted on a wafer. 24 (b) is a work in which a plurality of semiconductor chips or a laminated chip of TSV (Through Silicon Via) is mounted on a wafer. 24 (c) is a work in which a plurality of water-receiving chips (semiconductor chips) are mounted on a wafer (substrate). 24 (d) is a work in which a plurality of MEMS (Micro Electro Mechanical Systems) chips are mounted on a wafer. 24 (e) is a work in which a plurality of semiconductor chips and bumps or vias are mounted on an interposer substrate. 24 (f) is a work in which a plurality of laminated chips and vias are mounted on a substrate. Fig. 24 (g) is a work in which a plurality of semiconductor chips are fixed to a carrier (e.g., stainless steel, glass, or wafer) with a release sheet such as a heat peeling sheet interposed therebetween. The resin may be supplied to these in a shape similar to that of the package shown by the broken line in the same drawing.
For example, as the operation control system of the resin supply unit, a configuration as shown in Fig. 25 can be considered. In this configuration, a resin sealing device including a PC (Personal Computer) having an input section, a control section, a transmitting section and a display section, and a receiver section, a control section, a storage section, and a table (stage) driver is communicably connected. A drive control pattern is created on the PC side for each pattern ID, and is transmitted to the resin sealing apparatus and stored. On the resin sealing apparatus side, a pattern ID is set for each product (work), and the pattern ID is read to supply the resin so as to be a desired pattern (actual supply pattern). Since the speed is not stable at the time of starting the table, a dummy pattern may be included in the drive control pattern, and the resin may be supplied after the movement speed of the table becomes constant.
For example, in the first embodiment, the case where the resin receiving section is fixed and the workpiece mounting section is moved (scanned) has been described. However, the present invention is not limited to this case, and the case where the resin delivery portion is moved (scanned) and the workpiece mounting portion is fixed may be used. In this case, when the granular resin is supplied with good accuracy, the resin dropping portion and the movable portion around the resin dropping portion are enlarged, and the resin dropping portion is scanned in the XY directions with respect to the workpiece loading portion, .
Hereinafter, a description will be given with reference to Fig. 26 of a technique capable of supplying granular resin with good accuracy even when the workpiece mounting portion is fixed and the resin discharge portion is moved. Fig. 26 is a view for explaining a modification of the resin supply unit 12 (hereinafter referred to as a

Next, the resin supplying step (resin delivering step) using the
Specifically, the granular resin is fed back and forth in the longitudinal direction of the
As a result, the granular resin is fed to the strip-shaped region of one row by one discharging operation, so that the granular resin is uniformly supplied to the region where the strip-shaped regions are arranged. In this case, the supply amount per one line of the area is measured by the weighing
Further, a single strip-shaped area formed by one discharging operation may be partially or wholly overlapped. For example, when the granular resin is dropped between the semiconductor chips mounted in a matrix on the work W, the strip-shaped regions are dropped so as to form repeatedly, whereby compared with the case where the granular resin is dropped onto the chip You can also increase the supply. Therefore, it is possible to reduce the unevenness of the upper surface of the granular resin dropped on the work W, thereby reducing the resin flow in the compression molding, thereby improving the molding quality.
