Description

Receiving jig, manufacturing method of receiving jig, and resin

INDUSTRIAL APPLICABILITY The present invention is a receiving jig for supporting an object having a convex shape (an electronic board on which a component is mounted or various industrial products) on a convex surface having the convex shape, a manufacturing method thereof, and these. It relates to resin.

In creating a substrate (hereinafter also referred to as a substrate) on which electronic components are mounted, generally, electronic components (hereinafter also referred to as components) are mounted on both sides of a substrate in a substrate used in a high-performance electronic device. Has been. In a board on which components are mounted on both sides, the component is mounted on one side of the both sides, and then the component is mounted on the opposite side. When the component is mounted on the opposite surface, the mounted surface is supported by the receiving jig.

FIG. 1A is a diagram illustrating an example of a substrate 100 on which a component 112 is mounted on one side.

As shown in FIG. 1A, the object (substrate 100) having a convex shape (the convex shape of the component 112) is supported by the receiving jig on the convex surface having the convex shape (the mounting surface 110 on which the component 112 is mounted). Is done. Thereby, the component 112 is mounted on the opposite surface 120 while the opposite surface 120 on which the component 112 is not yet mounted is kept horizontal.

At this time, it is necessary to prevent unnecessary stress (pressure or scratches) from being applied to the mounted component 112 on the substrate 100. For example, a metal jig or a hard resin containing carbon cut is used as the receiving jig so that the mounted component 112 does not contact the metal or the like constituting the receiving jig. For example, when a support jig that supports the substrate 100 with a support pin is used, the tip of the support pin may be a cushion such as a spring or rubber, or the tip of the tip disclosed in Patent Document 1 may be used. In this way, unnecessary stress is not applied to the mounted component 112.

Japanese Patent No. 5746763

By the way, many objects such as the substrate 100 or various industrial products are absorbed by static electricity, for example, destruction of the component 112 due to leakage current to the component 112 mounted on the static electricity substrate 100 or static electricity. It is affected by static electricity such as contamination of the object by the attached garbage. Therefore, the receiving jig needs to have antistatic performance.

Also, when the object is supported by the receiving jig, it is necessary to prevent the object from being destroyed by unnecessary contact with the object by the receiving jig. For this purpose, the receiving jig needs to be configured to receive the object at a portion other than the portion where the object is easily damaged, or to be flexible so that the object is not subjected to stress even if it hits the receiving jig. Thus, there is a demand for a receiving jig that is unlikely to generate stress that may cause pressure or damage to an object. Here, a demerit of a commonly used receiving jig will be described.

For example, a method of supporting an object with support pins is a method often used as an object in mounting or inspection on the substrate 100.

FIG. 1B is a side view showing a state where the receiving jig 200 including the support pins 202 supports the substrate 100. In FIG. 1B, only three components 112 among the components 112 mounted on the substrate 100 are shown.

As shown in FIG. 1B, the substrate 100 is supported by the support pins 202 of the receiving jig 200 in the dead space between the adjacent components 112. In order to support the substrate 100 with the support pins 202, it is necessary to support the substrate 100 in many points, and it is necessary to provide a lot of dead space in the substrate 100. However, as a highly functional electronic device in recent years, for example, in a smartphone or the like, the support pins 202 in the substrate 100 are supported by increasing the density of mounting of the component 112 on the substrate 100 by making the smartphone light and thin. There is a tendency for dead space to disappear. In addition, efforts have been made to reduce the area of the substrate 100 in order to reduce costs for low-functional electronic devices, and there is a tendency for dead space to be eliminated as with high-functional electronic devices.

Further, when the object is supported by the support pins 202, the object is likely to be distorted, tilted, or vibrated because it is supported by a point, and an error is likely to occur in the work performed on the object (such as mounting or inspection).

Also, when the substrate 100 or the like is supported by the support pins 202, warpage or the like occurs in the substrate 100, and an electronic component mounted by the pressure due to this may malfunction.

Further, when the object is supported by the support pins 202, the support pins 202 must be erected in accordance with the convex shape of the object (for example, the mounting position of the component 112 on the board 100). If a mistake is made, the object becomes defective in the manufacturing process of the object, resulting in a loss. Moreover, since the manufacturing process is operating every day, it is difficult to visually manage the deterioration of the support pins 202. Therefore, the quality such as mounting failure due to deterioration of parts constituting the support pin 202 (for example, parts such as a spring or rubber at the tip of the support pin 202 to prevent the object from being damaged by impact or pressure). It is difficult to suppress loss in advance.

Thus, since the receiving jig 200 provided with the support pins 202 has the disadvantages described above, the method using the receiving jig 200 provided with the support pins 202 is not used.

On the other hand, when supporting an object using a NC (Numerical Control) machine tool with a metal (for example, aluminum) or a carbon kneading resin (a resin in which carbon is kneaded in ABS or the like), it does not hit the convex shape of the object. There is a receiving jig having a machined hole that is machined to a large depth.

FIG. 1C is a cross-sectional view showing a state in which the receiving jig 300 having the processing hole 302 supports the substrate 100 as an object. In FIG. 1C, a cross section of a portion where the three components 112 of the substrate 100 are fitted in the processing hole 302 is shown.

The receiving jig 300 is made of metal or carbon-containing hard resin, and is not flexible and hard. Therefore, if the object is displaced when the object is mounted on the receiving jig 300, there is a high possibility that the object is damaged or damaged. Therefore, the processing range of the processing hole 302 of the receiving jig 300 is widened. Therefore, the processing time becomes long, which causes an increase in processing cost and an increase in cost for responding to short delivery date production. At the time of prototyping an object such as the substrate 100, the receiving jig 300 may be changed due to, for example, an increase in the number of components 112 or a change in the mounting position of the components 112, but each change requires cost and lead time.

Also, a special processing machine is required for cutting. Since it is difficult in terms of cost and know-how to install the cutting machine in its own factory, production is outsourced to an outside contractor, and costs and lead time are required.

As described above, since the receiving jig 300 is costly, it is more costly to create the receiving jig 300 for each production of the object. Therefore, it is necessary to store the created receiving jig 300 for a long period of time. For example, a large storage space is required in a factory.

Also, when the receiving jig 300 is made of metal, it is heavy and difficult to handle. On the other hand, when the receiving jig 300 is made of a hard resin containing carbon in order to make the receiving jig 300 lighter, the carbon is easily peeled off, and the carbon adheres to an object such as the substrate 100, resulting in a market failure such as a short circuit. Sometimes.

As described above, the receiving jig 300 cut by using a hard resin containing metal or carbon has a demerit that it cannot be easily formed as described above and is expensive.

Therefore, an object of the present invention is to provide a receiving jig, a manufacturing method of the receiving jig, and a resin that can be easily created and can suppress the influence and stress due to static electricity on the object to be supported.

Note that each of the embodiments described below shows a preferred specific example of the present invention. Therefore, the numerical values, shapes, materials, components, arrangement and connection forms of components, and steps (processes) and order of steps shown in the following embodiments are examples, and the present invention is limited. is not. Therefore, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims showing the highest concept of the present invention are described as optional constituent elements.

Each figure is a schematic diagram and is not necessarily shown strictly. Moreover, in each figure, the same code | symbol is attached | subjected about the same component.

(Embodiment)
Hereinafter, embodiments will be described with reference to FIGS. 2 to 10B. In the following description, the object supported by the receiving jig is often described as the substrate 100. However, the object is not limited to the substrate 100, and may be a workpiece used in general manufacturing processes such as various industrial products. There may be.

[Receiving jig]
First, the configuration of the receiving jig will be described with reference to FIGS.

FIG. 2 is a diagram illustrating an example of the receiving jig 10 according to the embodiment. FIG. 2 also shows a substrate 100 supported by the receiving jig 10 in addition to the receiving jig 10. Although six components 112 are mounted on the substrate 100 shown in FIG. 2, 1 to 5 components 112 may be mounted, or seven or more components 112 may be mounted.

The receiving jig 10 is a receiving jig for supporting an object having a convex shape on a convex surface having the convex shape. In the present embodiment, the object is a substrate on which at least one component 112 is mounted, and the convex shape is the shape of the component 112 mounted on the substrate 100. Therefore, the receiving jig 10 supports the substrate 100 on the mounting surface 110 on which the component 112 is mounted. The object is not limited to the substrate 100 but may be a workpiece used in general manufacturing processes such as various industrial products.

The receiving jig 10 is made of a resin having a concave portion 12 corresponding to the contour of the convex shape (the convex shape of the component 112). That is, the receiving jig 10 itself is a resin. The resin will be described in detail with reference to FIGS. 10A and 10B, which will be described later. The hardness measured by the Asker C-type hardness meter is 60 degrees to 90 degrees, and the volume resistivity is 10 ² Ω · cm to 10 ⁷ Ω · It is a resin that is cm. In other words, this resin is a resin having high conductivity and flexibility. The concave portion 12 has a concave shape obtained when a mold having a convex shape (the convex shape of the component 112) is taken. The recess 12 is not formed by cutting, but is formed by taking the mold of the component 112 mounted on the mounting surface 110. Therefore, as shown in FIG. 2, the concave portion 12 has a concave shape corresponding to the contour of the component 112. Thus, when the substrate 100 is set on the receiving jig 10 with the mounting surface 110 facing the receiving jig 10, the receiving jig 10 has the component 112 on the mounting surface 110 fitted in the recess 12. In this state, the substrate 100 is supported.

FIG. 3 is a diagram illustrating a state in which the receiving jig 10 according to the embodiment supports the substrate 100.

As shown in FIG. 3, the receiving jig 10 supports the substrate 100 on the mounting surface 110, so that the component 112 is mounted on the opposite surface 120 of the mounting surface 110 or the substrate 100 is inspected on the opposite surface 120. Etc. Further, since the receiving jig 10 supports the multi-sided substrate, the multi-sided substrate can be divided.

FIG. 4 is a cross-sectional view illustrating a state where the receiving jig 10 according to the embodiment supports the substrate 100. FIG. 4 shows a cross section taken along the IV-IV plane shown in FIG.

Since the recess 12 is formed by taking the mold of the component 112, the receiving jig 10 supports the substrate 100 while wrapping the component 112 in the recess 12, as shown in FIG. As shown in FIGS. 2 and 4, the recess 12 has a bottom surface smaller than the opening of the recess 12 and has a wall surface inclined from the opening toward the bottom. That is, the recess 12 has an inverted frustum shape. The recess 12 may have an inverted truncated pyramid shape or an inverted truncated cone shape depending on the shape of the component 112. For example, the bottom surface of the recess 12 is the same size as the top surface of the component 112 (the lower surface of the component 112 in FIGS. 2 and 4) fitted in the recess 12, and the recess 12 is directed from the bottom surface toward the opening. It has an expanding shape.

Thus, the receiving jig 10 has a hardness of 60 to 90 degrees as measured by an Asker C-type hardness meter, and is made of a resin having a volume resistivity of 10 ² Ω · cm to 10 ⁷ Ω · cm. It is a tool and is not obtained by cutting, but has a concave recess 12 obtained by taking a convex mold of the object.

[Manufacturing method of receiving jig]
Next, a method for manufacturing the receiving jig 10 having the concave portion 12 having the convex shape of the object, particularly a method for taking the convex shape of the object will be described with reference to FIGS.

FIG. 5 is a flowchart showing an example of a method for manufacturing the receiving jig 10 according to the embodiment. In the following, for example, a person performs a method for manufacturing the receiving jig 10, but a machine for manufacturing the receiving jig 10 may be used. Details of step S11 to step S15 will be described with reference to FIGS. 6A to 6E. In FIGS. 6A to 6E, the object 100, the convex surface, and the convex shape portion are mounted on the substrate 100 shown in FIG. A surface 110 and a part 112 are provided.

First, the object is placed on the base so that the convex surface of the object faces upward (step S11). Step S11 will be described with reference to FIG. 6A.

FIG. 6A is a diagram for explaining the placing step according to the embodiment.

6A, the base 50 has, for example, a substantially rectangular parallelepiped shape, and the substrate 100 is placed on the surface of the base 50. At this time, the substrate 100 is placed on the base 50 so that the mounting surface 110, which is the surface supported by the receiving jig 10, faces upward.

Next, at least one of the release film and the cloth is put on the convex surface side of the object placed on the base 50 (step S12). Step S12 will be described with reference to FIG. 6B.

FIG. 6B is a diagram for explaining the steps to be covered according to the embodiment. FIG. 6B shows a state where the release film 20 is placed on the substrate 100.

The release film 20 used in step S12 needs to be a film that satisfies a plurality of conditions shown below. Although details will be described later, since the receiving jig 10 is formed by taking a mold through the release film 20, when the release film 20 expands and contracts, the surface of the receiving jig 10 becomes the release film 20. It becomes a wavy shape due to the expansion and contraction of. Therefore, the release film 20 needs to be a film with a small amount of expansion and contraction due to heat and pressure. Moreover, when the resin put in step S14 described later adheres to the release film 20, the shape of the receiving jig 10 such as the recess 12 may be collapsed when the release film 20 and the resin are peeled off. The mold film 20 needs to be a film that is difficult to adhere. Further, when the resin penetrates into the release film 20, the object is contaminated. Therefore, the release film 20 needs to be a film in which the resin does not easily penetrate. Further, the release film 20 needs to be a film that can withstand the heating of the resin in step S16 described later. The heat resistant temperature of the release film 20 is preferably about 100 to 400 degrees, and more preferably 200 degrees or more. Further, the release film 20 needs to be a film that can clearly mold the part 112 on the mounting surface 110 even through the release film 20. In addition, the cloth which satisfy | fills the conditions mentioned above may be used instead of the release film 20 by step S12.

As the release film 20 that satisfies these conditions, a fluororesin film, a silicon resin film, a heat-resistant film coated with a release agent, or the like is used. When the resin is put without the release film 20 being placed on the substrate 100, the substrate 100 is contaminated by the resin, and adheres to the substrate 100 when the resin is cured. In order to prevent these, the release film 20 is placed on the substrate 100. Step S12 will be described in more detail with reference to FIG.

Next, a frame-shaped outer portion whose height relative to the base 50 is higher than the height of the convex portion of the convex surface so as to surround the target object covered with at least one of the release film 20 and the cloth in a top view of the target object. The mold is installed on the base 50 (step S13). Step S13 will be described with reference to FIG. 6C.

FIG. 6C is a diagram for explaining the installation steps according to the embodiment.

In step S13, the outer mold 60, which is a frame-shaped mold, is used to copy the shape of the component 112 mounted on the mounting surface 110 of the substrate 100 with the resin put in step S14. The outer mold 60 has, for example, a rectangular tube shape, and the size in the frame of the outer mold 60 in a top view is substantially the same as or slightly larger than the size of the substrate 100, so that the substrate 100 can be surrounded by the outer mold 60. . As shown in FIG. 6C, the outer mold 60 is installed on the base 50 while surrounding the substrate 100. The height of the outer mold 60 from the base 50 when the outer mold 60 is installed on the base 50 is higher than the height of the component 112 from the base 50 when the substrate 100 is placed on the base 50. Thereby, when resin is put in the frame of the outer mold 60, the top surface of the component 112 can be immersed in the resin.

Next, resin is put in the frame of the outer mold 60 installed on the base 50 (step S14). Step S14 will be described with reference to FIG. 6D.

FIG. 6D is a diagram for explaining the steps to be performed according to the embodiment.

As shown in FIG. 6D, the resin 40 is put on the release film 20 in the frame of the outer mold 60. The resin 40 is a resin having a hardness of 60 degrees to 90 degrees as measured by an Asker C-type hardness meter and a volume resistivity of 10 ² Ω · cm to 10 ⁷ Ω · cm after curing. The resin 40 is, for example, a liquid resin. The amount in which the resin 40 is put is an amount corresponding to 20% to 95% of the volume in the frame of the outer mold 60. The resin 40 may be a plate-like, particle-like (particle size is not particularly limited), pellet-like, or gel-like resin. In the case where the resin 40 is in the form of particles, a larger amount of the resin 40 is added than in the case where the resin 40 is in the form of gel. Although details will be described later, the resin 40 is cured in a state in which the concave portion 12 corresponding to the convex contour of the object is formed when the receiving jig 10 is formed.

Next, an inner mold having an outer diameter corresponding to the inner diameter of the outer mold 60 is pressed against the resin 40 within the frame of the outer mold 60 in which the resin 40 is placed (step S15). Step S15 will be described with reference to FIG. 6E.

FIG. 6E is a diagram for explaining the pressing step according to the embodiment.

As shown in FIG. 6E, an inner mold 70 having an outer diameter matching the inner diameter of the outer mold 60 is used, and in order to clarify the convex shape of the component 112 of the substrate 100 when the resin 40 is cured, Within the frame of the mold 60, pressure is applied to the resin 40 from above by the inner mold 70. For example, a lid 80 is provided on the upper part of the inner mold 70. The size of the lid 80 when viewed from above is, for example, a size corresponding to the outer diameter of the outer mold 60. Step S15 will be described in more detail with reference to FIG.

The base 50, the outer mold 60, and the inner mold 70 (also collectively referred to as a mold) are less deformed even in a temperature environment of 80 ° C. or higher, such as metal or wood, and do not burn, burn, or produce contaminants. The material is used. In addition, the mold is subjected to non-adhesive surface treatment so that the resin 40 put in step S14 does not stick to the mold when cured. Non-adhesive surface treatment is, for example, fluorine resin coating treatment, silicon resin coating treatment, non-adhesive composite coating treatment, or the like. The thickness of the non-adhesive surface treatment is, for example, 200 μm or less.

Next, the resin 40 is heated in a state where the inner mold 70 is pressed against the resin 40 (step S16). When the resin 40 is, for example, a liquid resin that is a thermosetting resin, the resin 40 is cured by being heated. The resin 40 is heated at a temperature of 70 to 360 degrees, for example, according to the heat-resistant temperature of the substrate 100 or the like. Moreover, it heats for 10 minutes to 70 minutes according to heating temperature, for example. The relationship between the heating time and the heating temperature is, for example, 100 to 120 degrees for 60 minutes and 200 to 260 degrees for about 30 minutes, but there are variations in the environment around the furnace body. Further, the heating temperature and the heating time are controlled by the type of the curing agent included in the resin 40.

In addition, in the case where the resin 40 is a resin having thermoplasticity, for example, a resin in a plate shape, a particle shape, or a pellet shape, the resin 40 is heated and semi-molten (including softening) in a state where the inner mold 70 is pressed against the resin 40. For example, it is cooled at room temperature and cured.

The heating furnace for heating the resin 40 may be a reflow furnace for mounting electronic components. In addition, if a heating furnace is an apparatus which can heat the resin 40, it will not specifically limit.

In the case where the resin 40 is a resin having thermoplasticity, for example, in the case of a plate-like, particle-like, or pellet-like resin, the resin 40 is heated and semi-molten before the step of putting it into the frame of the outer mold 60. May be entered. In this case, instead of step S <b> 16, the resin 40 is cooled and cured at room temperature, for example, with the inner mold 70 pressed against the resin 40.

Then, the cured resin 40 is taken out from the mold, and the cured resin 40 becomes the receiving jig 10.

Here, the details of step S12 will be described with reference to FIG.

FIG. 7 is a cross-sectional view showing a state in which the release film 20 is covered on the substrate 100 in the covering step according to the embodiment. FIG. 7 shows a cross section at a location where three parts 112 on the near side in FIG. 6B are arranged. 7 and the subsequent drawings will be described using the substrate 100, the mounting surface 110, and the component 112 shown in FIG. 2 as the object, the convex surface, and the convex shape portion, respectively.

In order to make the mold of the component 112 on the mounting surface 110 clear even through the mold release film 20, the mold release film 20 placed on the substrate 100 enters between the components 112 as shown in FIG. There is a need. In order for the release film 20 to enter between the parts 112, the release film 20 should be thin and easy to bend. The thickness of the release film 20 is, for example, 25 μm to 500 μm. A cloth may be used instead of the release film 20. The thickness of the cloth is, for example, 500 μm to 1000 μm.

Further, as shown in FIG. 7, the release film 20 is placed on the substrate 100 while the space 22 is provided outside the side surface of the component 112. That is, the release film 20 is placed on the substrate 100 so that the side surface of the component 112 and the release film 20 do not adhere to each other. Thereby, the part which has wrapped the components 112 of the release film 20 becomes a frustum shape. Therefore, as described with reference to FIG. 4, the recess 12 has an inverted frustum shape formed by taking a frustum-shaped mold.

In addition, the release film 20 covered on the substrate 100 may be one sheet or a plurality of sheets. A plurality of types of films having different properties may be laminated on the substrate 100 in order to reduce expansion and contraction of the release film 20 due to heating in step S16. Moreover, the release film 20 having the same property may be laminated on the substrate 100. Even when a cloth is used instead of the release film 20, the cloth covered on the substrate 100 may be one sheet or plural sheets. In order to reduce the expansion and contraction of the cloth due to heating in step S16, a plurality of types of cloth having different properties may be laminated on the substrate 100. A cloth having the same property may be laminated on the substrate 100.

Moreover, both the release film 20 and the cloth may be put on the substrate 100.

FIG. 8 is a cross-sectional view showing a state in which the release film 20 and the cloth 30 are covered with the substrate 100 in the covering step according to the embodiment. FIG. 8 shows a cross section at a position where three parts 112 on the near side in FIG. 6B are arranged when both the release film 20 and the cloth 30 are covered with the substrate 100.

Resin 40 may shrink after being cured. That is, the size of the recess 12 of the receiving jig 10 may be reduced. Therefore, a cloth 30 having a thickness corresponding to the shrinkage amount of the resin 40 is placed on the substrate 100. In addition, when both the release film 20 and the cloth 30 are covered on the substrate 100, the release film 20 may be covered after the cloth 30 is covered on the substrate 100. Thereby, it is not necessary to use a cloth having the property that the resin 40 is difficult to adhere as the cloth 30.

Details of step S15 will be described with reference to FIG.

FIG. 9 is a cross-sectional view showing a state where the resin 40 is pressed against the release film 20 and the cloth 30 in the pressing step according to the embodiment. In FIG. 9, a screw 90 and a spring 92 not shown in FIG. 6E are shown. For example, the screws 90 are provided through the lid 80 at four corners in the top view of the lid 80, and the spring 92 is provided between the lid 80 and the screw head of the screw 90. In FIG. 9, for the sake of explanation, a cross section of a part where three parts 112 are arranged and a part where a screw 90 and a spring 92 are provided is shown on one drawing.

When the inner mold 70 is pressed against the resin 40 in the frame of the outer mold 60, it is necessary to release the gas in the frame of the outer mold 60. As shown in FIG. A clearance a is provided between the outer peripheral surface of the mold 70. However, in order to prevent the resin 40 from entering the clearance a, the resin 40 is pressed against the inner mold 70 in a state where the clearance a is 50 μm to 300 μm. The size of the clearance a is selected from the above range depending on the viscosity of the resin 40 and the like.

Further, for example, mounting or inspection is performed on the substrate 100 while the substrate 100 is supported by the receiving jig 10, so that the surface that supports the mounting surface 110 of the receiving jig 10 and the opposite surface are horizontal. There must be. Therefore, when the receiving jig 10 is created, the resin 40 needs to be pressed against the inner mold 70 with the bottom surface of the inner mold 70 being horizontal with respect to the surface of the base 50 on which the substrate 100 is placed. Moreover, when the resin 40 is heated in a state where it is pressed against the inner mold 70, it is necessary to keep the respective surfaces horizontal.

The method of keeping each surface horizontal is not particularly limited, but for example, a screw, a ball screw, a belt, a weight, or a spring is used. In FIG. 9, screws 90 and springs 92 are used to keep the respective surfaces horizontal. A plurality of screws 90 (for example, screws 90 provided at the four corners of the lid 80) passing through the lid 80 are screwed into the outer mold 60 while adjusting the screwing amounts, so that each surface is kept horizontal. The resin 40 is pressed against the inner mold 70. At this time, a spiral spring 92 is used as a buffer between the screw head of the screw 90 and the lid 80. This further improves the horizontal accuracy.

As described above, the hardness of the Asker C-type hardness tester is 60 to 90 degrees and the volume resistivity is 10 ² Ω · cm to 10 ⁷ Ω · cm. As a result, a receiving jig 10 having a concave recess 12 obtained by taking a convex mold of the object is created. The receiving jig 10 can be cut by a router or the like, and the shape of the recess 12 can be easily corrected after the receiving jig 10 is formed.

The manufacturing method includes a step of placing an object such that the convex surface faces upward on the base 50, and at least one of the release film 20 and the cloth 30 from the convex surface side of the object placed on the base 50. Covering the step. Moreover, the said manufacturing method is higher than the said height of the convex-shaped part of a convex surface so that the target with which at least one of the release film 20 and the cloth 30 was covered may be enclosed in the top view of a target object. A step of installing a high frame-shaped outer mold 60 on the base 50. Further, in the manufacturing method, the hardness of the hardened Asker C-type hardness meter is 60 to 90 degrees and the volume resistivity is 10 ² Ω · cm in the frame of the outer mold 60 installed on the base 50.

And including.

As a result, the receiving jig 10 can be easily created simply by taking a mold as compared to the supporting pin or cutting receiving jig. Further, since the receiving jig 10 is made of a flexible resin having a hardness of 60 degrees to 90 degrees as measured by an Asker C type hardness tester, scratches or stress is given to the object supported by the receiving jig 10. Absent. Furthermore, since the receiving jig 10 has the recessed part 12 which took the type | mold of the target object, it supports a target object so that it may wrap including the convex shape of a target object. Therefore, for example, in component mounting when the object is the substrate 100 or the like, it is possible to increase the printing accuracy of solder or the like and the component mounting accuracy, and the substrate 100 can be of high quality. Further, receiving jig 10, the volume resistivity is a resin which is ^{^{10 2 Ω · cm ~ 10 7}} Ω · cm, even if the substrate 100 where the object is mounted in the component 112, the leakage current due to static electricity It is possible to suppress the contamination of the object due to dust.

Moreover, since the convex mold | type of a target object is taken through the mold release film 20 or the cloth 30, it can suppress that a target object is contaminated with the resin 40. FIG.

In the heating step, the resin 40 is heated in a state where the inner mold 70 is pressed against the resin 40 after the pressing step. Further, in the heating step, the resin 40 may be heated before the adding step, and in the adding step, the resin 40 heated in the heating step may be put in the frame of the outer mold 60.

Moreover, the release film 20 is a film in which a release agent is coated on a fluororesin film, a silicon resin film, or a heat-resistant film.

Thereby, since the amount of expansion and contraction due to the heat and pressure of the release film 20 is reduced, the surface of the receiving jig 10 is suppressed from being wavy due to the expansion and contraction of the release film 20. In addition, since the cured resin 40 is less likely to adhere to the release film 20, the shape of the receiving jig 10 such as the recess 12 is prevented from collapsing when the release film 20 and the cured resin are peeled off. Moreover, since it becomes difficult for the resin 40 to penetrate into the release film 20, the contamination of the object is further suppressed. Further, the release film 20 can withstand the heating temperature when the resin 40 is heated. In addition, a convex mold on the convex surface of the object can be clearly obtained even through the release film 20.

The outer mold 60 and the inner mold 70 are molds that have been subjected to fluorine resin coating treatment, silicon resin coating treatment, or non-adhesive composite coating treatment.

In the pressing step, the inner mold 70 is pressed in a state where the clearance a between the inner peripheral surface of the outer mold 60 and the outer peripheral surface of the inner mold 70 is 50 μm to 300 μm.

Thereby, it is possible to suppress the resin 40 from entering the clearance a while venting the gas when the inner mold 70 is pressed.

In the heating step, the resin 40 is heated at a temperature of 70 to 360 degrees.

Thus, the resin 40 is heated at a temperature of 70 to 360 degrees, so that the resin 40 is cured when the resin 40 is a thermosetting resin, and is semi-molten when the resin 40 is a thermoplastic resin. Then it is cooled and hardened. Then, the resin 40 is 90 degrees from the hardness of 60 degrees due to curing after the Asker-C hardness meter, and the volume resistivity is in the resin is ^{^{10 2 Ω · cm ~ 10 7}} Ω · cm.

The resin 40 is a resin in which a conductive material is blended with one of a thermosetting resin and a thermoplastic resin, and the weight part of the conductive material with respect to one of the thermosetting resin and the thermoplastic resin. Is 0.3 to 20 parts by weight.

Thereby, the volume resistivity of the resin 40 can be set to 10 ² Ω · cm to 10 ⁷ Ω · cm.

Thereby, the resin 40 can be selected and blended from the above materials. In addition, since the conductive material is a carbon allotrope such as carbon nanotube, graphene, or graphite, the strength against peeling is higher than when the resin constituting the receiving jig 10 is a carbon-containing resin. Therefore, it is difficult for dust due to carbon peeling to occur, and when the target is the substrate 100 or the like, it is possible to suppress the occurrence of a market defect such as an unnecessary short circuit on the substrate 100 due to dust.

The resin 40 is a resin in which an electrically conductive material, a curing agent, and a curing accelerator are blended with an epoxy resin as a thermosetting resin.
