[Modes for carrying out the invention]

[0011] In the following explanation, the directions indicated by arrows U, D, L, R, F, and B in the diagram will be defined as upward, downward, left, right, forward, and backward, respectively.

[0012] <Supply Jig 10> The configuration of the supply jig 10 according to one embodiment of the present invention will be described below.

[0013] The supply jig 10 shown in Fig. 1 is for collectively supplying the release film F and the resin material R to a resin molding apparatus 50 (see Fig. 10). In particular, the supply jig 10 according to the present embodiment can supply the release film F and the resin material R to the resin molding apparatus 50 by manual operation of an operator. The supply jig 10 mainly includes a film holder 100 and a resin material holder 200. The film holder 100 and the resin material holder 200 are configured to be detachable from each other. Hereinafter, the configurations of the film holder 100 and the resin material holder 200 will be described.

[0014] <Film holder 100> The film holder 100 shown in Fig. 2 is capable of holding the release film F. The film holder 100 mainly includes a main body portion 110, a first pressing portion 120, a compression spring 130, a mounting pin 140, a second pressing portion 150, and a bolt 160.

[0015] The main body portion 110 is a portion that forms the main structure of the film holder 100. The main body portion 110 is formed in a rectangular shape in plan view having a long side extending in the left - right direction and a short side extending in the front - rear direction. The main body portion 110 mainly includes an opening 111, a positioning recess 112, a fixing recess 113, a first recess 114, and a second recess 115.

[0016] The opening 111 is formed at the central portion of the main body portion 110 and is a portion that opens in the up - down direction. The opening 111 is formed in a rectangular shape in plan view. By forming the opening 111, the main body portion 110 is formed in an annular (frame - like) shape in plan view. The opening 111 is formed in a shape corresponding to the outer shape of the upper portion of the lower mold 52 (see Fig. 10) of the resin molding apparatus 50 described later. Thereby, the film holder 100 can be fitted onto the upper portion of the lower mold 52.

[0017] The positioning recesses 112 are for relative positioning of the film holder 100 and the resin material holder 200, which will be described later. The positioning recesses 112 are formed by recessing the rear side surface of the main body 110 toward the front. One positioning recess 112 is formed on the left side and one on the right side of the rear side surface of the main body 110. The position and number of positioning recesses 112 are not particularly limited.

[0018] The fixing recesses 113 shown in Figures 2 and 3 are used to fix the resin material holder 200 to the film holder 100. The fixing recesses 113 are formed by recessing the lower part of the left and right sides of the main body 110 inwards. One fixing recess 113 is formed on the front and one on the rear of the left and right sides of the main body 110. Note that the fixing recess 113 formed on the left side of the main body 110 is not shown. Furthermore, the position and number of fixing recesses 113 are not particularly limited.

[0019] The first recesses 114 shown in Figures 2 to 4 are for accommodating the first retaining portion 120. The first recesses 114 are formed near both the left and right ends of the main body portion 110. The first recesses 114 are formed in a longitudinal shape extending from the front end to the rear end of the main body portion 110. The first recesses 114 are formed by recessing the upper surface of the main body portion 110 downwards.

[0020] The film holder 100 is formed to be generally symmetrical in the front-to-back and left-to-right directions. Therefore, in the following explanation, we will focus on the right rear part of the film holder 100, as shown in Figures 3 and 4, and will omit illustrations and explanations of other parts as appropriate.

[0021] The second recess 115 shown in Figures 3 and 4 is for housing the compression spring 130. The second recess 115 is formed near both the front and rear ends of the first recess 114. The second recess 115 is formed by further recessing the bottom surface of the first recess 114 downwards. The second recess 115 is formed in a circular shape in plan view. The diameter of the second recess 115 is formed to be smaller than the width of the first recess 114 in the left-right direction.

[0022] The first pressing portion 120 shown in Figures 2 to 4 is for pressing the release film F from below. The first pressing portion 120 is formed in a plate shape. The first pressing portion 120 is formed in a rectangular shape in plan view with its longitudinal direction oriented in the front-to-back direction. The width of the first pressing portion 120 in the left-to-right direction is formed to be slightly smaller than the width of the first recess 114 in the left-to-right direction. The width (thickness) of the first pressing portion 120 in the up-to-down direction is formed to be smaller than the depth (width in the up-to-down direction) of the first recess 114. The first pressing portion 120 is positioned inside the first recess 114.

[0023] The compression spring 130 shown in Figure 4 is for applying an upward force to the first retaining portion 120 (hereinafter also referred to as "biasing"). The compression spring 130 is one embodiment of the second biasing portion according to the present invention. The compression spring 130 is positioned inside the second recess 115 in a partially contracted state, with its expansion and contraction direction oriented vertically. The upper end of the compression spring 130 contacts the first retaining portion 120 from below. This allows the compression spring 130 to apply an upward force to the first retaining portion 120.

[0024] The mounting pin 140 shown in Figures 2 and 4 is for attaching the first retaining portion 120 to the main body portion 110. The mounting pin 140 is formed in a substantially cylindrical shape with its axis oriented in the vertical direction. The upper end of the mounting pin 140 is formed to have a larger diameter than the lower end. The mounting pin 140 is positioned to penetrate near both the front and rear ends of the first retaining portion 120. The lower end of the mounting pin 140 is fixed to the bottom of the second recess 115. By fixing the mounting pin 140 in this way, the first retaining portion 120 is supported so as to be movable along the longitudinal direction (vertical direction) of the mounting pin 140 inside the first recess 114. Furthermore, upward movement of the first retaining portion 120 (outside the first recess 114) is restricted by the upper end of the mounting pin 140.

[0025] The second pressing portion 150 shown in Figures 2 to 4 is for pressing the release film F from above. The second pressing portion 150 is formed in a plate shape. In plan view, the second pressing portion 150 is formed in a substantially rectangular shape with its longitudinal direction oriented in the front-to-back direction. Both the front and rear ends of the second pressing portion 150 are formed to spread out to the left and right, and bolts 160 are provided therein. In plan view, the second pressing portion 150 is formed to overlap with the first pressing portion 120. The second pressing portion 150 mainly comprises a projection 151, an opening 152, and a tapered surface 153.

[0026] The projection 151 is a portion formed to protrude downward from the bottom surface of the second pressing portion 150. The projection 151 is formed on the portion facing the first pressing portion 120 in the vertical direction. In other words, the projection 151 is formed in a rectangular shape when viewed from the bottom, with its longitudinal direction oriented in the front-to-back direction, similar to the first pressing portion 120.

[0027] The opening 152 is a through hole formed to penetrate the second retaining portion 150 vertically. The opening 152 is formed in a position opposite the mounting pin 140 in the vertical direction. This prevents interference between the second retaining portion 150 and the upper end of the mounting pin 140.

[0028] The tapered surfaces 153 shown in Figures 2 and 3 are for guiding the claw portion 250 of the resin material holder 200, which will be described later. The tapered surfaces 153 are one embodiment of the second guide surface according to the present invention. The tapered surfaces 153 are formed by obliquely cutting out the left and right outer ends of the upper surface of the second pressing portion 150. As a result, the tapered surfaces 153 are formed in an inclined surface shape that slopes downward toward the left and right outer sides of the second pressing portion 150. One tapered surface 153 is formed on the front and one on the rear of the second pressing portion 150.

[0029] The bolt 160 shown in Figures 2 to 4 is for fixing the second retaining portion 150 to the main body portion 110. By inserting the bolt 160 into the second retaining portion 150 from above and fastening its lower end to the main body portion 110, the second retaining portion 150 can be fixed to the main body portion 110.

[0030] When the release film F is held by the film holder 100 configured in this way, with the second pressing portion 150 removed from the main body portion 110, the release film F is placed over the entire area of ​​the main body portion 110 so as to cover the opening 111 of the main body portion 110 from above. At this time, as shown in Figure 4(a), the release film F is placed on the main body portion 110 and the first pressing portion 120. In this state, the second pressing portion 150 is placed on the release film F and fixed to the main body portion 110 by bolts 160.

[0031] When the bolt 160 is fastened to the main body 110, the protrusion 151 of the second pressing portion 150 pushes the first pressing portion 120 downward, as shown in Figure 4(b). This pulls the release film F so that it enters the inside of the first recess 114, thereby applying tension to the release film F and smoothing out wrinkles. Furthermore, the release film F can be firmly held between the second pressing portion 150 fastened by the bolt 160 and the first pressing portion 120 which is subjected to upward force by the compression spring 130. In particular, in this embodiment, since the release film F is bent so that it enters the inside of the first recess 114, the release film F can be held even more firmly.

[0032] In this embodiment, the main body portion 110 is provided with a first pressing portion 120 and a second pressing portion 150 at both ends in the longitudinal direction (left-right direction). This allows tension to be applied along the longitudinal direction of the long release film F placed on the main body portion 110, and wrinkles can be efficiently smoothed out.

[0033] <Resin material holder 200> The resin material holder 200 shown in Figure 5 is capable of holding the resin material R when attached to the film holder 100. The resin material holder 200 mainly comprises a main body 210, a regulating part 220, a first handle 230, a second handle 240, a claw part 250, and a torsion spring 260.

[0034] The main body portion 210 shown in Figures 5 and 6 forms the main structure of the resin material holder 200. The main body portion 210 is formed in a rectangular shape in plan view, having long sides extending in the left-right direction and short sides extending in the front-back direction. An opening is formed in the center of the main body portion 210, into which a regulating portion 220, which will be described later, can be placed. The main body portion 210 mainly comprises a bearing portion 211, a second regulating portion 212, a first positioning portion 213, and a second positioning portion 214.

[0035] The main body 210 is formed to be generally symmetrical in the front-to-back and left-to-right directions. Therefore, in the following explanation, we will focus on the right rear part of the main body 210, as shown in Figure 6, and will omit illustrations and explanations of other parts as appropriate.

[0036] The bearing portion 211 rotatably supports the second handle 240. The bearing portions 211 are provided at each of the four corners of the upper surface of the main body portion 210. The bearing portions 211 are positioned to protrude upward from the main body portion 210. The bearing portion 211 is provided with a first regulating portion 211a.

[0037] The first restricting portion 211a shown in Figure 6 is for restricting the rotation of the second handle 240 to a predetermined position. The first restricting portion 211a is formed in a cylindrical shape with its axis oriented in the front-rear direction. The first restricting portion 211a is positioned to protrude rearward from the rear side surface of the bearing portion 211.

[0038] The second restricting portion 212 is for restricting the rotation of the claw portion 250 at a predetermined position. The second restricting portion 212 is provided on the left and right sides of the main body portion 210. The second restricting portion 212 is positioned to protrude outward from the left and right sides of the main body portion 210. The second restricting portion 212 is positioned on the inside of the claw portion 250 in the left-right direction, facing the claw portion 250.

[0039] The first positioning section 213 shown in Figure 5 is for relative positioning of the resin material holder 200 and the lower mold 52 of the resin molding apparatus 50, which will be described later. The first positioning section 213 is formed on the front, rear, left, and right sides of the main body 210. The first positioning section 213 is formed in a concave shape by recessing the lower surface of the main body 210 upwards. Positioning projections (not shown) formed on the lower mold 52 of the resin molding apparatus 50 can be inserted into the first positioning section 213, thereby positioning the lower mold 52 of the resin molding apparatus 50 and the resin material holder 200. The position and number of first positioning sections 213 are not particularly limited.

[0040] The second positioning portion 214 is for relative positioning of the resin material holder 200 and the film holder 100. The second positioning portion 214 is formed at a position corresponding to the positioning recess 112 of the film holder 100. Specifically, the second positioning portion 214 is formed on the rear side surface of the main body portion 210. The second positioning portion 214 is formed on the left and right sides of the rear side surface of the main body portion 210, respectively. The second positioning portion 214 is formed to protrude downward from the main body portion 210. By inserting the second positioning portion 214 into the positioning recess 112 (see Figure 2) formed in the film holder 100, relative positioning of the resin material holder 200 and the film holder 100 can be achieved.

[0041] The defining portion 220 is for defining the area in which the resin material R will be contained. The defining portion 220 is formed in a rectangular frame shape in plan view, corresponding to the opening of the main body portion 210. The defining portion 220 is attached to the main body portion 210 in a state where it is fitted into the opening of the main body portion 210. An opening 221 is formed in the defining portion 220.

[0042] The opening 221 is formed in the central part of the defining portion 220 and is a portion that opens in the vertical direction. The opening 221 is formed in a shape corresponding to the cavity of the resin molding apparatus 50. In this embodiment, the opening 221 is formed in a rectangular shape in plan view, but the shape of the opening 221 can be arbitrarily changed according to the shape of the cavity or the object to be molded. In this embodiment, the main body portion 210 and the defining portion 220 form a frame in a rectangular shape in plan view, and the resin material R can be held inside it. The main body portion 210 and the defining portion 220 are one embodiment of the resin holding portion according to the present invention.

[0043] The first handle 230 is capable of being gripped by an operator. The first handle 230 is one embodiment of the first gripping part according to the present invention. The first handle 230 is provided on the left and right sides of the main body 210, respectively. The first handle 230 is formed in an inverted U-shape when viewed from the side. Both ends of the first handle 230 are fixed to the front and rear of the upper surface of the main body 210, respectively. As a result, the first handle 230 is provided to protrude upward from the upper surface of the main body 210.

[0044] The second handle 240 shown in Figures 5 and 6 can be gripped by an operator and can operate the claw portion 250, which will be described later. The second handle 240 is one embodiment of the operating portion and second gripping portion according to the present invention. The second handle 240 is provided on the left and right portions of the main body portion 210, respectively. The second handle 240 mainly comprises a shaft portion 241 and a grip 242.

[0045] The shaft portion 241 is a substantially cylindrical part with its axis oriented in the front-rear direction. The shaft portion 241 is rotatably supported by bearing portions 211 provided at the front and rear of the main body portion 210. The shaft portion 241 is positioned to extend further rearward from the rear bearing portion 211. In this way, the shaft portion 241 is provided so as to protrude laterally (rearward) from the main body portion 210. A grip 242 made of a material that is easy for an operator to grasp (for example, rubber) is provided at the rear end of the shaft portion 241. The shaft portion 241 is provided with a mounting portion 241a and a regulating pin 241b.

[0046] The mounting portion 241a shown in Figure 6 is for attaching the regulating pin 241b to the shaft portion 241. The mounting portion 241a is formed in an annular shape and is fixed to the shaft portion 241 immediately behind the bearing portion 211. This allows the mounting portion 241a to rotate integrally with the second handle 240.

[0047] The regulating pin 241b is for restricting the rotation of the second handle 240 to a predetermined position. The regulating pin 241b is formed in a substantially cylindrical shape. The regulating pin 241b is provided so as to protrude radially outward from the outer circumferential surface of the mounting portion 241a. When the right-hand second handle 240 shown in Figure 6 rotates to a certain extent counterclockwise when viewed from the rear, the regulating pin 241b comes into contact with the first regulating portion 211a. This restricts the rotation of the second handle 240 in the clockwise direction when viewed from the rear.

[0048] The claw portion 250 shown in Figures 5 and 6 is for fixing the resin material holder 200 to the film holder 100. The claw portion 250 is one embodiment of the fixing part according to the present invention. Two claw portions 250 are provided along the longitudinal direction of the second handle 240. The claw portion 250 is fixed to the second handle 240 and can rotate integrally with the second handle 240. The claw portion 250 is formed to extend generally downward from the second handle 240. The lower part of the claw portion 250 is formed to protrude inward in the left-right direction. By hooking the lower part of the claw portion 250 (the inwardly protruding portion) into the fixing recess 113 of the film holder 100, the resin material holder 200 can be fixed to the film holder 100 (see Figure 7).

[0049] In the following, among the rotational positions of the claw portion 250, the position in which the claw portion 250 can be hooked onto the fixing recess 113 of the film holder 100 and fixed to the film holder 100 will be referred to as the "fixed position." Also, among the rotational positions of the claw portion 250, the position in which the fixing of the claw portion 250 to the film holder 100 is released will be referred to as the "released position."

[0050] As shown in Figure 6, a tapered surface 251 is formed on the claw portion 250. The tapered surface 251 is one embodiment of the first guide surface according to the present invention. The tapered surface 251 is formed by obliquely cutting out the bottom surface of the claw portion 250. The tapered surface 251 is formed in an inclined surface shape that slopes downward toward the left and right outer sides.

[0051] Second restricting portions 212 are positioned on the left and right inner sides of the claw portion 250. When the right-side second handle 240 shown in Figure 6 rotates to a certain extent clockwise when viewed from the rear, the claw portion 250 comes into contact with the second restricting portion 212. This restricts the rotation of the second handle 240 in the clockwise direction when viewed from the rear.

[0052] Furthermore, the specific shape of the claw portion 250 is not particularly limited, and it can be formed into any shape that can fix the film holder 100 and the resin material holder 200.

[0053] The torsion spring 260 applies force to the second handle 240 so that it rotates in a predetermined direction. The torsion spring 260 is one embodiment of the first force-applying part according to the present invention. The torsion spring 260 is provided on the second handle 240 behind the front bearing portion 211 and immediately in front of the rear bearing portion 211. The torsion spring 260 constantly biases the second handle 240 so that the lower part of the claw portion 250 faces inward to the left and right. Taking the second handle 240 shown in Figure 6 as an example, the torsion spring 260 constantly biases the second handle 240 in a clockwise direction when viewed from the rear.

[0054] <Outline of the method for holding the release film F and resin material R using the supply jig 10> The following describes how to hold the release film F and resin material R using the supply jig 10 (film holder 100 and resin material holder 200) configured as described above, with reference to Figures 8 and 9. The following procedure is performed manually by an operator. Note that Figures 8 and 9 use schematic diagrams that simplify the configuration of each part for explanatory purposes.

[0055] First, as shown in Figure 8(a), the release film F is held in the film holder 100 with the film holder 100 and the resin material holder 200 separated. At this time, the second pressing part 150 is not attached to the film holder 100.

[0056] When holding the release film F in the film holder 100, a film setting device 30 as shown in Figure 9 can be used. The film setting device 30 has a box-shaped body 31 with a recess 31b on its upper surface that corresponds to the film holder 100. When the release film F is held in the film holder 100, the film holder 100 is pre-placed in the recess 31b.

[0057] Inside the main body 31 is a roll holder 32 that holds the release film F wound in a roll. The release film F wound on the roll holder 32 is guided by a guide roller 33 and supplied to the upper side of the main body 31 through a slit 31a formed on the upper surface of the main body 31.

[0058] The release film F supplied to the upper side of the main body 31 is positioned above the film holder 100, and is held by the film holder 100 by the second pressing part 150 being fixed to the film holder 100 with bolts 160. The method of holding the release film F by the film holder 100 has been described above, so the explanation will be omitted.

[0059] Subsequently, the release film F is cut at an appropriate position, separating the release film F wound around the roll holding section 32 from the release film F held by the film holder 100. In this way, the release film F required for one resin molding can be held by the film holder 100.

[0060] Although a detailed explanation will be omitted, the film setting device 30 may also be equipped with appropriate mechanisms such as a tension-applying mechanism for applying tension to the release film F, a holding mechanism for holding the release film F, and a cutting mechanism for cutting the release film F.

[0061] Next, as shown in Figure 8(b), the resin material holder 200 is moved downward from above the film holder 100. This operation can be performed while the film holder 100 is held in the film setting device 30 (main body 31).

[0062] When moving the resin material holder 200 downwards, the operator can easily align the resin material holder 200 with the film holder 100 by gripping the first handle 230 (see Figure 5).

[0063] When the resin material holder 200 approaches the film holder 100 to a certain extent, the tapered surface 251 of the claw portion 250, which is being forced toward the fixed position, comes into contact with the film holder 100 (more specifically, the tapered surface 153 formed on the second pressing portion 150 (see Figure 3)). If the resin material holder 200 is moved further downward in this state, the claw portion 250 is pushed open by the film holder 100 and rotates to the release position. This allows the resin material holder 200 to move further downward.

[0064] As shown in Figure 8(c), when the defining portion 220 of the resin material holder 200 descends to the point where it contacts the release film F held by the film holder 100 from above, the biasing force of the torsion spring 260 causes the claw portion 250 to rotate inward again to the fixed position (more specifically, to the position where it catches in the fixed recess 113 (see Figure 7)). This fixes the resin material holder 200 to the film holder 100. In this state, the opening 221 of the defining portion 220 is positioned to face the release film F held by the film holder 100 from above. The defining portion 220 (opening 221) positioned on the release film F defines a space capable of accommodating the resin material R. At this time, the second positioning portion 214 of the resin material holder 200 is fitted into the positioning recess 112 of the film holder 100, thereby enabling relative positioning of the film holder 100 and the resin material holder 200.

[0065] Next, as shown in Figure 8(d), the resin material R is contained inside the specified section 220. At this time, the operator can grasp the first handle 230 or the second handle 240 and shake the resin material holder 200 back and forth and side to side to distribute the resin material R uniformly inside the specified section 220. It is also possible to ensure uniformity of the resin material R by supplying it to the resin material holder 200 using an appropriate jig. For example, the resin material R can be placed on a mesh-like plate and dropped from above the specified section 220 so that it passes through the mesh, thereby dispersing the resin material R and distributing it uniformly inside the specified section 220. Any resin material R can be used as the resin material R, such as granular or liquid.

[0066] In this way, the release film F and the resin material R can be held together by the film holder 100 and the resin material holder 200 (supply jig 10), which are fixed to each other.

[0067] <Resin molding method> The following describes a method for supplying release film F and resin material R to a resin molding apparatus 50 using a supply jig 10, primarily using Figure 10, and performing resin molding. The supply of release film F and resin material R using the supply jig 10 is performed manually by an operator. In Figure 10, a schematic diagram is used to show the configuration of each part in a simplified manner for explanatory purposes. Also, in Figure 10, only the cross-sectional end views of each part are shown, but for the sake of explanation, the hatching indicating the cross-section of each part has been omitted except for the resin material R.

[0068] First, in the release film and resin material holding process, the release film F and resin material R are held using the supply jig 10 as described above (see Figure 8).

[0069] Next, in the substrate supply process, the substrate W, which is the object to be molded, is supplied to the upper mold 51 of the resin molding apparatus 50 (see Figure 10(a)). The substrate W is held by adsorption to the lower surface of the upper mold 51 with the electronic elements such as semiconductor chips that are to be resin-encapsulated facing downwards.

[0070] The substrate W can be a semiconductor substrate such as a silicon wafer, a metal substrate, a glass substrate, a ceramic substrate, or a resin substrate. The substrate W may or may not have wiring. While this embodiment uses a rectangular substrate W, the shape of the substrate W is not particularly limited; for example, a circular substrate W can also be used.

[0071] Next, in the release film and resin material supply process, the release film F and resin material R held in the supply jig 10 are supplied to the lower mold 52 of the resin molding apparatus 50 (see Figure 10(b)). At this time, the upper part of the lower mold 52 (side member 55) is fitted into the opening 111 of the film holder 100. The first positioning part 213 of the resin material holder 200 (see Figure 5) is fitted into a positioning projection (not shown) formed on the lower mold 52, thereby enabling relative positioning of the supply jig 10 and the lower mold 52.

[0072] In this case, the worker can grasp the second handle 240 and move the supply jig 10 to the resin molding device 50. This allows the worker to perform the work from a position away from the lower mold 52, even if the lower mold 52 has been preheated, thereby improving work efficiency.

[0073] In this state, the upper surface of the film holder 100 and the upper surface of the lower mold 52 are roughly aligned vertically. The release film F held by the film holder 100 is positioned to be in contact with the upper surface of the lower mold 52. The resin material R held by the resin material holder 200 is positioned above the cavity 53 of the lower mold 52. The release film and resin material supply process is one embodiment of the supply process according to the present invention.

[0074] Next, in the adsorption process, the release film F is adsorbed onto the lower mold 52 (see Figure 10(c)). As a result, the release film F is adsorbed so as to follow the cavity 53 of the lower mold 52. Consequently, the resin material R placed on top of the release film F is contained within the cavity 53.

[0075] Next, in the separation process, the resin material holder 200 is removed from the film holder 100, and the resin material holder 200 is removed from the resin molding apparatus 50 (see Figure 10(d)). At this time, the operator can release the fixing of the resin material holder 200 to the film holder 100 by rotating the second handle 240 so that the claw portion 250 opens outward (to the release position). The operator can then take out the resin material holder 200 by holding the second handle 240. In this way, the second handle 240 for holding the resin material holder 200 also serves as an operating tool for manipulating the claw portion 250, allowing the operator to perform the work efficiently.

[0076] Next, during the mold clamping process, a mold clamping mechanism (not shown) is driven, causing the base plate 54 of the lower mold 52 to rise (see Figure 10(e)). As the base plate 54 rises, the side members 55 that form the sides of the cavity 53 come into contact with the bottom surface of the substrate W. As the base plate 54 rises further, the elastic member 56 positioned between the base plate 54 and the side members 55 contracts. This causes the bottom member 57 that forms the bottom surface of the cavity 53 to move relatively upward relative to the side members 55. This pressurizes the resin material R inside the cavity 53. When the bottom member 57 has risen to a certain extent, the mold clamping is completed.

[0077] Next, in the resin molding process, the resin material R is pressed and left for a predetermined time. This causes the temperature of the thermosetting resin material R to rise further, and the resin material R hardens. As a result, resin molding can be performed on the substrate W.

[0078] Next, in the mold opening process, the upper mold 51 and the lower mold 52 are opened. Specifically, the lower mold 52 moves downward so that it separates from the upper mold 51 by a mold clamping mechanism (not shown).

[0079] Next, in the unloading process, the resin-molded substrate W (resin-molded product) is unloaded from the resin molding apparatus 50. The film holder 100 is also unloaded from the resin molding apparatus 50. When unloading the film holder 100, the resin material holder 200 is reattached to the film holder 100 (see Figure 10(f)), and the film holder 100 can be removed from the resin molding apparatus 50 using the second handle 240.

[0080] By using the supply jig 10 in this way, the release film F and resin material R can be supplied to the resin molding apparatus 50 all at once, thereby improving work efficiency.

[0081] Although embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and appropriate modifications can be made within the scope of the technical idea of ​​the invention as described in the claims.

[0082] For example, in the above embodiment, an example was shown in which a film setting device 30 is used to hold the release film F and resin material R in the supply jig 10, but the present invention is not limited to this, and various other devices can be used.

[0083] Furthermore, although the above embodiment shows an example in which the film holder 100 and the resin material holder 200 are fixed using the claw portion 250, the present invention is not limited thereto, and the method of fixing the film holder 100 and the resin material holder 200 can be arbitrarily changed. For example, it is also possible to fix the two using fasteners such as bolts and nuts.

[0084] Furthermore, the force-applying components (compression spring 130 and torsion spring 260) exemplified in the above embodiment are merely examples, and various other force-applying members (leaf springs, tension springs, elastic members, etc.) can be used.

[0085] Furthermore, although the above embodiment shows an example in which the resin material R is held collectively in a rectangular opening 221 (see Figure 5), the present invention is not limited to this. For example, it is also possible to provide partitions that further divide the opening 221 into multiple regions, and to hold uniformly measured amounts of resin material R in each region. This makes it possible to equalize the resin material R within the opening 221 and further improve the quality of the resin molded product.

[0086] Furthermore, for example, the specified portion 220 of the resin material holder 200 shown in Figure 5 can be configured to move relative to the main body portion 210 within a predetermined range. As a result, when the film holder 100 and the resin material holder 200 are fixed together, as shown in Figure 8(c), the specified portion 220 is pressed against the release film F held by the film holder 100 by its own weight. By pressing the specified portion 220 against the release film F in this way, it is possible to prevent the resin material R from entering between the release film F and the specified portion 220 or spilling out.

Specifically, the release film F and resin material R can be supplied to the resin molding apparatus 50 together with the film holder 100 and the resin material holder 200 integrated. This makes it possible to efficiently supply the release film F and resin material R. Furthermore, since the release film F and resin material R can be supplied together, similar to when using a resin molding apparatus (automatic machine) that automatically supplies the release film F and resin material R to the resin molding apparatus 50 in one go, the molding conditions of an automatic machine can be reproduced even with manual operation.
