Description of the Invention: [Technical Field of the Invention] The present invention relates to a method of manufacturing a soft and hard composite board. In particular, the present invention relates to a method of making soft and hard composite panels in a more economical manner to meet the requirements of environmental protection. [Prior Art] In the process of manufacturing a circuit board, in order to accommodate more circuit structures in a limited space, a technique of alternately stacking soft and hard boards is often used. Hard boards provide the basic circuit architecture, while flexible boards with flexing characteristics can shuttle, bend, or overlap between hard boards, and accommodate the most circuit structures in a limited space as designed. The traditional soft and hard composite board is manufactured by pressing the soft board and the hard board in the inner layer. Fig. 1 is a schematic view showing a method of fabricating a conventional soft and hard composite board. In order to coordinate the spatially overlapping stacking of the hard board 111 and the soft board 121, the hard board layer 110 is partially evacuated to form a hard board waste 112 μ with the upper and lower layers of the soft board 120. Similarly, the soft board layer 120 will also partially form a soft board waste 122 to match the upper and lower hard boards 110. In the same board, the number of layers is the same. In the case of a single hard or soft layer, such a manufacturing method actually cuts off many useful parts, such as hard board waste 112 and soft board waste 122. These cut-out parts, because they cannot be recycled and reused, are similar to the waste of 4 1377893 resources. Such a manufacturing process not only bears the cost of discarding materials, but also does not cherish the example of the limited resources of the earth. It cannot meet the mainstream concept of green production. Obviously, the traditional soft and hard composite board manufacturing method can not meet the mainstream of the industry to cooperate with green production. Therefore, it is urgent to create a new method to maximize the hardness of the hard layer or the soft layer. The typesetting utilization rate can meet the mainstream concept of industrial green production. SUMMARY OF THE INVENTION The present invention is directed to a novel method of making a soft and hard composite panel. In the case of a single hard or soft layer, the use of typesetting can be maximized, so that a large number of useful hard or soft layers are not discarded. This method of production not only saves the cost of production, but also meets the mainstream concept of industrial production with green production. Lu's invention proposes a method for manufacturing a soft and hard composite panel. First, a pre-cut inner panel, a pre-cut soft panel 'fixing member and a whole outer panel are provided. These pre-cut inner panels have a multi-layered structure of hard plates. - The entire outer panel can contain copper and semi-cured film. The fixing member can accommodate at least a sheet pre-cut inner panel and a piece of pre-cut soft board to be placed therein. Secondly, the whole outer panel, the pre-cut inner panel and the pre-cut soft board are placed in the fixing member according to a predetermined layout, so that the pre-cut soft board will be separately prepared from the pre-cut inner panel and the whole. The outer sheet is in direct contact. Then, after the entire outer panel, the pre-cut inner panel and the pre-cut soft panel are combined, the fixing member can be removed. 1377893 In one embodiment of the invention, the fixture includes a jig hole to assist in combining the outer panel, the pre-cut inner panel, and the pre-cut soft panel. In another preferred embodiment of the present invention, after the fixing member is removed, the entire outer panel is also cut in accordance with a predetermined layout. [Embodiment] The present invention proposes a novel method of manufacturing a soft and hard composite panel. Figures 2-12 illustrate schematic views of a method of making a soft and hard composite panel of the present invention. Please refer to Figure 2. First, the pre-cut inner plates 211/215 are provided. The pre-cut inner plates 211/215 are obtained from a whole piece of hard plate 21 having a multi-layer structure, and are cut according to a predetermined size, and the sizes thereof may be different, for example, the pre-cut inner plate 211 and the pre-cut The good inner panel 215 is different in size. The desired multilayer structure 214 can have a stacked structure of two or more layers in accordance with the circuit design of the product. In a preferred embodiment of the present invention, 'when the pre-cut inner panel 211 is made, the best row board can be cut from the one-piece hard board 210 having a multi-layer structure according to the optimum board utilization rate. The utilization rate can be cut to the least amount of waste Μ] : as a reference target. In general, the lowest typographic utilization rate that is generally acceptable in the industry is 60-80%, and the use of the production method of the present invention can be improved to 7〇-9〇〇/. . The size and shape of the pre-cut inner plate 211 may be the same as or different from each other 211/215, as shown in Fig. 2. 213 pre-cut inner plate 211 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ One of the structural multilayer structures 224 has a pre-cut soft plate 221/225 in a 1374893 piece of flexible sheet 220 that is cut by a minimum of scrap 222 according to a predetermined size. The size and shape of the pre-cut soft plates 221-225 may be the same or different from each other. Depending on the situation, the pre-cut soft plate 221 may additionally include a drill hole 223 for assisting the alignment. In addition, the multilayer structure 224 is provided with conductive traces. The conductive traces may be on one or both sides of each of the flexible layers in the multilayer structure 224. Further, please refer to Fig. 4 to provide a full outer panel 230. A full sheet of outer sheet 230 may be a composite structure' for example comprising copper foil 231 and prepreg 232. Or as needed for the target thickness or stack design of the board structure, it may additionally include one or more layers of blank core layer (not shown) or may be semi-cured of two or more layers. Film 232/233 multi-layer structure design. The prepreg 232/233 can be pre-cut 232V233' if needed. Next, referring to Fig. 5, a fixing member 240 is provided for accommodating at least one pre-cut inner plate 211/215 and a pre-cut soft plate 221 . The fixing member 240 is used to integrate the pre-cut inner plate 211/215, the pre-cut flexible plate 221 and the entire outer plate 230. For convenience of alignment, the fixing member 240 may include at least one jig hole 241, for example, a jig 241 arranged in a specific pattern according to a predetermined layout to assist in combining the whole outer plate 230, the pre-cut inner plate 211 and A combination of pre-cut soft boards 221. The fixing member 240 of the present invention may be in the form of a work frame, and may be reused after combining the complete outer sheet 230, the pre-cut inner panel 211 and the pre-cut soft board 221, and the resource recycling according to the green environmental protection production. The mainstream concept 'this is another feature of the invention. After the whole outer plate 230, the pre-cut inner plate 211, the pre-cut soft plate 221 and the fixed 1378993 piece 240 are all ready, next, referring to FIG. 6, the whole outer plate 230 and the pre-cut inner plate can be used. The 211 and the pre-cut flexible board 221 are placed in the fixing member 240 in accordance with a predetermined layout. Combining the entire outer panel pre-cut inner panel 211 and . pre-cutting the soft panel 221 depends on the specifications of the finished product, as shown in Fig. 7. Usually, the combined pre-cut soft plate 221 and the pre-cut inner plate 211 are alternately stacked and partially overlapped. For example, the pre-cut flexible board 221 is located between the pre-cut inner plates 211/215. Or a composite stack design 'for example, a plurality of pre-cut soft board stacks and a plurality of pre-cut inner panels' form a soft board/inner board staggered overlap or upper and lower (inside and outside) lusymmetric soft board/inner board overlap. For example, 'soft board / inner board staggered stack can be inner board - soft board - inner board, inner board _ soft board - inner board - soft board - inner board, soft board _ inner board - soft board, soft board - Inner plate-soft board-inner board-soft board' or inner board-inner board-soft board_inner board_ inner board, inner board-soft board-soft board-inner board, inner board_inner board-soft board- Soft board - inner board - inner board, soft board - inner board - inner board · soft board, soft board _ soft board inner board - soft board - soft board ... etc. 'Making the pre-cut soft board in the pre-cut inner board The pre-cut inner plate is located between the pre-cut soft plates, the two adjacent pre-cut soft plates are in direct contact or the two adjacent pre-cut inner plates are in direct contact. Then, referring to FIG. 8, it is also possible to add on the outer surface of the pre-cut flexible panel 221 and the pre-cut inner panel 211, for example, at least one of the lower surface or the upper surface, or both. The entire outer panel 230, such as the pre-cut inner panel 211, is positioned between the entire outer panel 230 such that the pre-cut flexible panel 221 will directly contact the pre-cut inner panel 211 and the outer outer panel 230, respectively. Further, when the entire outer panel 230, the pre-cut inner panel 211, and the pre-cut flexible panel 221 are combined, the pre-cut soft panel 221 can also be bent to produce a specific stacked structure. After the whole outer sheet 230 is combined, [S 18: 577 milk pre-cut inner panel 2 should be 5 and the pre-cut soft board 221 < further can be further carried out. A press-fitting process is as shown in Fig. 9 to Fix the whole piece of outer plate 230, pre-cut inside, board 2 brain 5 and pre-cut soft board milk. In particular, when a whole piece of outer panel is retracted, the semi-cured film 233 is included. It is also possible to assist the pre-cut inner panel 2U to make an electrical connection with the pre-cut flexible panel 221 during the pressing process. For example, after the conductive paste or the conductive paste is applied as an electrically-bonded adhesive material at the conductive position, the press-bonding is performed. Alternatively, after the pressing, the pre-cut inner plate 211/215 and the φ pre-cut soft plate 221 are placed corresponding to the position of the region which is formed as the via hole, and the subsequent through holes are used to form an electrical connection. Further, a dielectric layer may be present between the upper and lower pre-cut inner plates 211, for example, a prepreg or an insulative core layer. If the fixing member 240 includes the jig hole 241, the stylus 250 (pin) can be used to assist in assembling the entire outer plate 230, the pre-cut inner plate 211 and the pre-cut soft plate 221, as shown in Fig. 1. If the fixing member 240 does not include the jig hole 241, an optical alignment method may be used to assist in assembling the entire outer plate 230, the pre-cut inner plate 211/215 and the pre-cut soft plate 221, so as to be superposed. The alignment is improved. Referring to Fig. 11, after the entire outer sheet 230, the pre-cut inner panel 211/215 and the pre-cut soft sheet 221 are completed, the fixing member 240 can be removed and reused. Next, referring to Fig. 12, the completed outer sheet 230, the pre-cut inner plate 211/215 and the pre-cut flexible sheet 221' can be cut according to the previously predetermined layout, and the entire outer sheet 230' can be cut. The soft and hard composite plate 260 includes an outer plate 230, a pre-cut inner plate 211/215 and a pre-cut soft plate 221 . Since the present invention can produce a pre-cut inner plate or a pre-cut soft plate from a whole inner plate 1378893 or a soft plate according to an optimal arrangement utilization ratio, then the most economical square wire can be recorded. Hard composite board. Series - Come, no longer discard big! Useful hard or soft layer.
