However, the substrate of the hard board material, or even the packaging process of the hard board substrate, still limits the sheet-type board until now, and the two reasons are that firstly, when the hard board is used for collecting and releasing the board, a large-diameter cylindrical cassette is needed to be used for collecting and storing the board so as to avoid damage caused by bending the board, and the product area needs to be kept in a non-contact manner, and secondly, strong rolling force is needed to roll the hard board into a cylinder.

The insulating layer 128c extends from one layer 129c and covers the side of the first copper foil layer 124a, the side of the glass fiber resin substrate 122a, and the side of the second copper foil layer 126a onto the other layer 129 c. Here, the recess structure C1 is suitable for placing the electronic component 10 therein, and then manufacturing the package product of the build-up board.

In another embodiment, please refer to fig. 2B and fig. 2D simultaneously, the hard board 120D of the present embodiment is similar to the hard board 120B of fig. 2B, and the difference is that: the hard plate 120d of the present embodiment is a package carrier plate using a stainless steel plate 122b with a groove structure C2 as a temporary substrate, and preferably, the thickness of the stainless steel plate 122b is, for example, 0.1 mm to 0.4 mm.

The insulating layer 128d extends from one layer 129d and covers the side of the stainless steel plate 122b to the other layer 129 d.

Referring to fig. 1A and fig. 1B again, a coating 140 is sprayed on the spiral grooves 112a of the upper cover plate 112, the spiral grooves 114a of the lower cover plate 114, and the spiral grooves 116a of the interposer 116, wherein the coating 140 is, for example, a teflon lubricant, but not limited thereto.

Finally, referring to fig. 1A and fig. 1C, the driving component 130 is fixed at one end of the hard board 120 to drive the hard board 120 to enter the spiral clamping grooves 112a, 114a, 116a from the opening of the cylindrical barrel 117 and the openings 112b, 114b, 116b of the corresponding spiral clamping grooves 112a, 114a, 116a, and the driving component 130 winds the rotating shaft 118 to drive the rotating shaft 118 to rotate to drive the hard board 120 to wind into a roll shape. At this time, the opposite sides of the hard board 120 are located in the spiral clamping groove 112a and the spiral clamping groove 114 a. Preferably, at least two of the interposer 116, the upper cover 112, and the lower cover 114 of the cassette 110 are in direct contact with the stiffener 120, wherein the contact between the stiffener 120 and the driving component 130 is a non-product area. Here, the driving component 130 is, for example, a cable or a flexible steel belt, and is fixed to the hard board 120 by means of clamping the hard board 120. The outer diameter of the hard sheet 120 wound into a roll is preferably between 800 mm and 1000 mm.

It should be noted that the tensile force applied by the driving assembly 130 to the stiffener 120 is determined by the sum of the friction force between the stiffener 120 and the upper cover 112, the lower cover 114 and the interposer 116, and the bending force for bending the stiffener 120 into a rolled sheet. Since the coating 140 of the teflon lubricant is coated on the spiral clamping grooves 112a of the upper cover plate 112, the spiral clamping grooves 114a of the lower cover plate 114, and the spiral clamping grooves 116a of the interposer 116, the friction coefficient thereof can be maintained at 0.1.

For example, if the size of the hard board 120 is 1.0 mm x610 mm x8000 mm, and the Young's modulus of the hard board 120 is 2500kg/mm ² The total pressure between the hard plate 120 and each slot is proportional to the length of the hard plate 120 entering the slot, and the maximum pressure of the hard plate 120 when it completely enters the slot is 132 kg. If calculated as a friction force of 0.1, the pulling force is 13.2 kg. In addition, the total pulling force is 15.2 kg when the folded plate force is 2 kg. If the size of the hard plate 120 is 1.75 mm x610 mm x8000 mm, and the Young's modulus of the hard plate 120 is 2500kg/mm ² The drum was rolled up to a diameter of 1000 mm and a maximum pressure of 443 kg. If calculated as a friction force of 0.1, the pulling force is 44.3 kg. In addition, the total pulling force is 51.46 kg when the folded plate force is 7.16 kg.

Fig. 3 is a schematic view illustrating a partial step of a method for manufacturing a roll hard sheet according to another embodiment of the invention. Referring to fig. 3 again, in application, two cassettes 110a, 110b may be provided as a plate feeding mechanism and a plate receiving mechanism, respectively, wherein the cassettes 110a, 110b are connected with the continuous production apparatus 10, and the hard plate 120 may be output from the side of the cassette 110a and be received into a roll from the side of the cassette 110b through the production of the continuous production apparatus 10. That is, the hard sheet 120 can be changed from a rolled shape to a flat shape when being discharged from the cassette 110a side, and the hard sheet 120 can be changed from a flat shape to a rolled shape when being received from the cassette 110b side.

For example, as the hard board 120a in fig. 2A is output from the cassette 110a side, the build-up structure is made by the continuous production apparatus 10, and then when the roll is received from the cassette 110b side, the hard board 120a may be a part of the product, and the thickness of the total structure of the product may be greater than 2.0 mm. At this time, the length of the accommodating roll type hard plate may be from 1.0 meter to more than 100 meters, and the width may be 125 mm to 1000 mm.

In another embodiment, as shown in fig. 2B, the hard board 120B is output from the side of the cassette 110a, and the build-up structure is manufactured by the continuous production apparatus 10, then the hard board 120B is separated from the two build-up products, and then the products are stored in rolls from the side of the cassette 110B. At this time, the thickness of the total structure of the product may be greater than 2.0 mm.

In summary, in the method for manufacturing a roll-type hard board of the present invention, the driving component is fixed at one end of the hard board to drive the hard board to enter the spiral clamping groove from the opening of the spiral clamping groove of the cassette, and the driving component (i.e. the cable or the flexible steel strip) winds the rotating shaft to drive the rotating shaft to rotate to drive the hard board to roll into a roll shape. Thus, the hard board with the thickness of 0.1 mm to 2.0 mm can form a coiled hard board. In short, the manufacturing method of the roll-type hard board has the advantages of simple and rapid manufacturing process. In addition, the manufacturing method of the roll hard board can also be used for folding and unfolding the hard board when the cassette is connected with the processing equipment.
