[Embodiment of the invention] Hereinafter, Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 4. Fig. 1 is a top view of the conveying sheet, Fig. 2 is a cross-sectional view along the sheet and the conveying direction, and Fig. 3 is along 580714

(4) A cross-sectional view of the sheet width direction. FIG. 4 is a schematic view of a manufacturing process. It should be noted that the magnification of the dimension in the thickness direction is much greater than that in the plane direction in the following figures. As shown in FIG. 1, the portion of the sheet body i with the contact plate is the same as the conventional example, that is, it is composed of the upper sheet 2, the spacer sheet 3 adhered to the lower sheet 2, and the contact plate 4. The above-mentioned contact plate 4 is adhered to the lower surface of the upper sheet 2 and is inserted into a through hole 5 provided in the spacer sheet 3. The upper sheet 2 is composed of an upper sheet 2 a and an upper adhesive layer 2 b, and is “bonded” to the spacer sheet 3 by the upper adhesive layer. The spacer sheet 3 is formed of the spacer film 3 a and the spacer adhesive layer 3 b. The sheet 1 has a through-hole 6 provided for assembling a component such as an LED. The sheet i having the above-mentioned structure is adhered to the belt-shaped conveying sheet 7 by the spacer adhesive layer 3 b, which is similar to the prior art so far. However, The conveying sheet 7 (shown in FIG. 2) is formed of a conveying sheet 7 a and a conveying adhesive layer 7 b. A strip-shaped protective sheet 8 is adhered to the lower part of the conveying sheet 7. However, the protective sheet 8 is not provided with an adhesive layer. The technology is different. Therefore, no adhesive is adhered to the outer peripheral part 下面 of the contact plate 4, and the two sides of the width direction of the transmission partition 7b remaining under the positioning hole 7c as shown in FIG. When the conveying sheet 7 ′ is rolled on the drum, there is no mutual connection. The following describes the manufacturing process of the above structure according to FIG. 4. First, the conveying sheet 7 a, the conveying point landing layer 7 b, and the conveying partition ^ are laminated. The sheet 7 is placed in a state of being wound on the drum 7R. It is then drawn into the processing line. On the other hand, the spacer sheet 3 laminated with the spacer film 3a, the spacer spacer layer 3b, and the spacer spacer 3C is placed in a state of being wound on the drum 311 and then Pulled out. When Yu Zhishan started to call Yang > ~ After pulling out 'spacer partition was peeled off immediately

580714 becomes debris and is rolled onto the drum 3S. After the conveyance sheet 7 and the spacer sheet 3 are adhered together, the positioning hole 7c and the through hole 5 of the contact board are processed by the punch 5P. At this time, since the transfer drilling layer 7b is formed of a weakly adhesive material, it is difficult to attach it to the processing device (the same applies to the following processing). After the upper sheet 2a laminated with the upper sheet 2a, the upper adhesive layer 2b, and the upper partition 2c is pulled out from the roller 2R, the upper partition 2c is immediately peeled off, and the residual sheet is rolled onto the roller 2S. The remaining upper sheet 2a and the upper adhesive layer 2b are adhered to the spacer sheet 3. A cutout is formed in the outer shape of the sheet 1 by a semicircular punch 1Η. At the same time, the through hole 6 is punched out by the punch 6P. Then, the useless portions of the upper sheet 2 and the spacer sheet 3 are peeled off together, and are wound onto the drum 2T as a residual sheet. The contact plate 4 is inserted into the through-hole 5 from the lower surface with respect to the residual sheet 1 by an inserter 41 and bonded to the lower surface of the upper adhesive layer 2b. Then, the conveying partition 7d with the through hole empty is taken up as a scrap, leaving only the portion on the lower side of the positioning hole 7c of the conveying sheet 7. And the lower surface of the conveyance sheet 7 (except the part on the lower side of the positioning hole 7c) is covered with the protective sheet 8 supplied from the roller 8R. Finally, the finished product is taken up in the drum 7T. Next, a second embodiment of the present invention will be described with reference to Figs. 5 to 8. Fig. 5 is a plan view of the conveyed sheet, Fig. 6 is a sectional view along the sheet conveying direction, Fig. 7 is a sectional view of the sheet width direction, and Fig. 8 is a schematic view of a manufacturing process. The description of the same parts as those of the first embodiment will be omitted. Compared with Example 1 to which the dot plate sheet is attached, the difference is that there is no spacer sheet 3. In this case, when the user connects on the product substrate, a part of the contact plate 4 of the upper sheet 2 projects in a convex shape. In addition, the transport sheet 7 and the protective sheet underneath 580714

(6) None of the sheets 8 had an adhesive layer. Therefore, in order to fix the protective sheet 8 to the conveying sheet 7, the fixing sheet 9 is adhered. The fixed sheet 9 is formed of a fixed sheet 9a and a fixed adhesive layer 9b, and its width is narrower than the transport sheet 7 and wider than the protective sheet 8. Therefore, the protective sheet 8 is held under the transport sheet 7. According to the above-mentioned structure, there is no need to worry about the lower peripheral portion 4c of the contact plate 4 coming into contact with the adhesive, as in the previous embodiment.

The manufacturing process of Example 2 will be described below. First, the conveyance sheet 7 is placed in a state wound on a drum 7R, and then pulled into a processing line. The conveyance sheet 7 is punched out of the positioning hole 7c and the through hole 5 of the contact board through the punch 5P. Then, the upper sheet 2 formed by laminating the upper sheet 2a, the upper adhesive layer 2b, and the upper partition 2c is pulled out from the roller 2R, and the upper partition 2c is immediately peeled into a residual sheet and rolled onto the roller 2S. And it is adhered to the conveyance sheet 7.

A semi-circular punch 1 is used to form a cutout in a part of the outer shape of the sheet body 1, and a punch hole 6P is punched out of the through hole 6 at the same time. Then, the useless part of the upper sheet 2 is peeled off, and it is rolled into the drum 2T as a scrap. The contact plate 4 is inserted into the through hole 5 from the lower surface of the residual sheet 1 by an inserter 41 and is bonded to the lower surface of the upper sheet 2a. The fixed sheet 9 formed of the fixed sheet 9a, the fixed adhesive layer 9b, and the fixed partition 9c and having a width smaller than the distance between the positioning holes 7c on both sides of the conveyance sheet 7 is pulled out from the roller 9R. Since the fixing sheet 9 does not cover the positioning holes 7c of the conveying sheet 7, the processing device-side positioning pins inserted into the positioning holes 7c are not contaminated by the adhesive. Therefore, product accuracy and yield are improved. And the fixed partition 9c is immediately rolled into the drum 9S as a residue; the fixed adhesive layer 9b is on one side, and a protective sheet 8 with a narrow width is bonded; and the above-mentioned 3 layers are processed from the above-mentioned conveying sheet 7 on the way of feeding The sides are glued. Finally, the finished product is rolled onto the drum 7T by -10- 580714 ⑺. In the above-mentioned embodiment, the conveying sheet 7 is continuous, and may be processed discretely. In addition, in this embodiment, only the contact board 4 is inserted at the through hole 5, but it is not limited to this method. Electronic components with electrodes can be installed together, and the effect is the same. Alternatively, a sheet-like material having various functions may be laminated on the upper sheet. The shape of the contact plate is not limited to a downward bowl-shaped structure, and may have various other applicable shapes.
