<<<<<<<< Details of the embodiment >>>>>>>
In the conventional method for manufacturing an electronic device using a printed wiring board, when the printed wiring board is housed in the housing of the electronic device, a dead space is generated between the printed wiring board and the housing. Since the dead space is not the same as the space inside the housing of the electronic device and the shape of the printed wiring board housed in the housing, the generation of dead space is unavoidable. However, the existence of dead space has made it difficult to miniaturize electronic devices.

Further, the electronic components mounted on the wiring board have different sizes, and in recent years, the number of electronic components mounted has increased. For this reason, the component mounting area of the printed wiring board is becoming insufficient.

The conventional method of producing and combining small printed wiring boards according to the above-mentioned functions has a possibility of cost advantage. However, in order to combine the wiring boards with each other, a separate fixing component is required. Furthermore, dead space and heat generation processing from electronic components cannot be solved.

For these reasons, there has been a demand for a structure that does not form a dead space, can be miniaturized in an electronic device, and can cope with heat generation from an electronic component.

<<<<<< Connectable three-dimensional structure block body 10 >>>>>>
<<< Direction, etc. >>>
As the direction with respect to the connectable three-dimensional structure block body 10, the axial direction and the extending direction are used. In addition, the extension means that it exists in an extended manner.

<Axial CD (Cylindrical CD)>
The axial direction CD is a direction along the cylinder axis CA of the cylinder portion 110 of the connectable three-dimensional structure block body 10. The connectable three-dimensional structure block body 10 and the tubular portion 110 will be described in detail later.

<Extended direction ED>
The extending direction ED is a direction perpendicular to the axial direction CD. The directions perpendicular to the axial direction CD are the first extending direction ED1 and the second extending direction ED2. The extending direction ED has a first extending direction ED1 and a second extending direction ED2. The second extending direction ED2 is a direction perpendicular to the first extending direction ED1.

The first extending direction ED1 is a direction along the long side surface portions 132 and 134, which will be described later. That is, the first extending direction ED1 is a direction perpendicular to the axial direction CD and a direction along the long side surface portions 132 and 134.

The second extending direction ED2 is a direction along the short side surface portions 136 and 138, which will be described later. That is, the second extending direction ED2 is a direction perpendicular to the axial direction CD and a direction along the short side surface portions 136 and 138.

When the side surface portion cannot distinguish between long and short, any direction may be used as the extending direction ED.

<Inside and outside>
The inside refers to a space or region surrounded by a cylinder portion 110 (side surface portions 132, 134, 136, 138) of the housing 100, which will be described later, and a direction toward the space or region. The inside also includes a region of the surface (inner surface, inner surface) of the side surface portions 132, 134, 136, 138.

The outside refers to a space or region extending in a direction away from the tubular portion 110 (side surface portions 132, 134, 136, 138) of the housing 100, or a direction toward the space or region. The outside also includes a region of the surface (outer surface, outer surface) of the side surface portions 132, 134, 136, 138.

<<<< Overview of the configuration of the connectable three-dimensional structure block 10 >>>>>
One connectable three-dimensional structure block body 10 functions as one electronic circuit block (unit electronic circuit) for forming an electronic circuit. A conductor pattern 200 (wiring pattern) is formed on the surface of the housing 100 (described later) of the connectable three-dimensional structure block body 10. The conductor pattern 200 and the wiring pattern will be described later. By electrically connecting and mounting the electronic component to the conductor pattern 200, one connectable three-dimensional structure block body 10 can function as a unit electronic circuit. By integrally forming the conductor pattern 200 on the surface of the housing 100 and further fixing and electrically connecting the electronic component to the conductor pattern 200, both the conductor pattern 200 and the electronic component are integrated with the housing 100.

Various desired conductor patterns 200 can be formed on the connectable three-dimensional structure block body 10. The connectable three-dimensional structure block body 10 can function as a unit electronic circuit. A plurality of various types of connectable three-dimensional structure block bodies 10 can be structurally connected to each other. Along with the structural connection, it also connects electrically. By structurally connecting a plurality of connectable three-dimensional structure blocks 10, a plurality of unit electronic circuits can be electrically connected. By combining and connecting a plurality of unit electronic circuits, it is possible to configure an electronic circuit that functions in an integrated manner.

Only the housing 100 can have the role of the conventional printed wiring board. For wiring, component mounting, etc., the front surface and the back surface of each constituent surface (for example, a side surface) constituting the housing 100 can be used. Dead space can be reduced by utilizing the entire configuration surface of the housing 100. Further, heat generated from the electronic components mounted on the housing 100 can also be discharged to the outside through the housing.

<<<< Specific configuration of the connectable three-dimensional structure block body >>>>>
Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a perspective view from the outer lid surface 182 showing the appearance of the connectable three-dimensional structure block body 10 according to the present embodiment. FIG. 2 is a perspective view from the outer lid surface 182 showing the appearance of the connectable three-dimensional structure block body 10 according to the present embodiment.

FIG. 4 is a perspective view from the inner lid surface 184 showing the appearance of the connectable three-dimensional structure block body 10 according to the present embodiment. FIG. 5 is a cross-sectional view taken along the line AA of FIG.

The connectable three-dimensional structure block body 10 includes a housing 100 and a conductor pattern 200.

<<< Housing 100 >>
After molding the three-dimensional substrate, the housing 100 can form a circuit on the surface of the housing 100, and then, if necessary, form a solder resist so that the component mounting portion opens. Examples of the molding material of the housing 100 include an inorganic material such as ceramic and an organic material using a resin.

Inorganic materials include silica, Neuburg silica soil, aluminum hydroxide, magnesium hydroxide, talc, clay, magnesium carbonate, calcium carbonate, natural mica, synthetic mica, barium sulfate, barium titanate, iron oxide, titanium oxide, and oxidation. Aluminum, glass powder, non-fibrous glass, glass fiber, carbon, carbon fiber, hydrotalcite, mineral wool, aluminum silicate, calcium silicate, zinc flower, silicon nitride, sialon, silicon carbide, aluminum hydroxide, etc. can be preferably used. can. As the organic material, a thermosetting resin and a thermoplastic resin can be preferably used.

The housing 100 is preferably made of a resin molded product, and a circuit formed in the resin molded product is preferable. It is desirable to use a thermoplastic resin or a thermosetting resin for the housing 100, which is light in weight and easy to mold. A known and commonly used resin can be used, but in particular, since the electronic component is mounted by solder in the housing 100, a fluororesin having excellent heat resistance, a polycarbonate polyacetal, a polyamide, a polyphenylene ether, an amorphous polyallylate, a polysulfon, etc. Thermal curing of engineering plastics such as polyether sulfone, polyphenylen sulphide, polyether ether ketone, polyimide, polyetherimide, liquid crystal polymer, phenol resin, epoxy resin, melamine resin, urea resin, unsaturated polyester, silicon resin, etc. Sexual resin is suitable.

There are a plurality of types of the housing 100. For example, some types of housings 100 have different shapes, sizes, structures, and the like. As will be described later, the conductor pattern 200 is integrally formed on the surface of the housing 100. By integrally forming the conductor pattern 200 on the surface, the housing 100 functions as a printed wiring board (printed wiring body). As will be described later, the conductor pattern 200 has a wiring pattern and a non-wiring pattern.

Even if the electronic circuits are different and the conductor patterns 200 are different, the housing 100 having the same shape, size, and structure may be diverted. By diverting the housing 100, the types of the housing 100 to be prepared can be suppressed.

The housing 100 is manufactured by mold molding, cutting molding, 3D printing with a 3D printer, or the like. Among them, mold molding is common, but the cost tends to be high in the manufacture of molds, and it is not profitable in the production of small lots and medium lots. Cost reduction can be achieved by manufacturing several types of common molds instead of dedicated molds. Further, by reducing the types of the housing 100, it is possible to simplify the management in the manufacturing process. The conductor pattern 200 will be described in detail later.

The housing 100 includes a tubular portion 110 and a protruding portion 170.

The side surface thickness ST is the shortest distance between the outer side surface 122 of the cylinder and the inner side surface 124 of the cylinder. The side surface thickness ST may be appropriately determined according to the strength required for the connectable three-dimensional structure block body and the like.

Further, the thickness ST1 of the long side surface portions 132 and 134 and the thickness ST2 of the short side surface portions 136 and 138 may be the same or different. If they are the same, the thicknesses ST1 and ST2 are equal to the side surface thickness ST. The thicknesses ST1, ST1 and ST2 may be determined according to the strength required for the connectable three-dimensional structure block body 10. Hereinafter, the thickness ST1 of the long side surface portions 132 and 134 and the thickness ST2 of the short side surface portions 136 and 138 are collectively referred to as the side surface portion thickness ST.

<<< Conductor pattern 200 (wiring pattern) >>>
The conductor pattern 200 is formed by a conductor. The type of conductor can be appropriately determined according to the type of resin, conductivity, durability, and the like.

The conductor pattern 200 is integrally formed on the surface of the housing 100. The conductor pattern 200 may be any as long as it can adhere to the surface of the housing 100 and maintain conductivity.

As a method for forming the conductor pattern 200 on the surface of the housing 100, a known method can be used and may be appropriately selected depending on the intended purpose. In particular, in the connectable three-dimensional structure block body 10, a non-conductive metal complex is dispersed in a molding resin which is a material of the housing 100, a three-dimensional substrate is molded using this molding resin, and then a laser beam is used as a conductor pattern.

The housing in which electronic components are attached to the wiring pattern functions as a printed circuit board (PCB). The electronic component may be either a passive component or an active component. The type, number, and arrangement of electronic components are determined according to the electronic circuit to be functioned.

The wiring pattern has a predetermined thickness (wiring pattern thickness) and a width (conductor width).

<Non-wiring pattern>
The non-wiring pattern is a pattern that does not form an electrical connection and does not form an electronic circuit. The non-wiring pattern is formed to improve the thickness and strength of the housing 100, or is formed as an alignment mark for determining the position of the housing 100.
