Preferred embodiments of the handheld circuit board according to the present invention will be described below with reference to the accompanying drawings, in which like elements will be described with like reference numerals.

Referring to fig. 1A to fig. 1F, fig. 1A is a schematic diagram of a handheld circuit board according to an embodiment of the invention.

Referring to fig. 1A and fig. 1B, the handheld circuit board 1 includes a substrate 11 and a medium layer 12. In addition, the manual circuit board 1 of the present embodiment further includes a battery 13, a switch element 14 and two electrochromic elements 15. It should be noted that the manual circuit board 1 of the present embodiment can be applied in the field of education for non-professional and younger ordinary users to arrange circuits by themselves according to the guidance of the medium layer 12 of the manual circuit board 1 so as to conduct the circuits and make the desired manual circuit board by DIY. Of course, in other embodiments, the manual circuit board 1 may be applied to other fields, such as scientific research, and the invention is not limited in particular.

In the present embodiment, the substrate 11 includes a coating layer (not shown), the coating layer is disposed on the surface of the substrate 11, and the medium layer 12 is disposed on a surface of the substrate 11 (i.e., disposed on the coating layer). That is, the coating layer is disposed between the substrate 11 and the medium layer 12. In addition, unlike the substrate of the general printed circuit board, the substrate 11 of the manual circuit board 1 of the embodiment can be selected from the following aspects, and the material can include: one or the combination of a wood substrate, a bamboo substrate, a paper substrate, a cotton substrate, a high-density fiber substrate and a resin substrate, and is mainly an insulating substrate. And substrate materials commonly used for printed circuit boards, such as aluminum substrates, iron substrates, paper phenol (phenol) copper laminated boards, paper Epoxy (Epoxy) copper laminated boards, Glass Epoxy (Glass-Epoxy) copper laminated boards, Glass Composite (Glass Composite) copper laminated boards, Glass Epoxy (Glass-Epoxy) or Glass benzene resin substrates, are not selected.

The medium layer 12 is disposed on the surface (coating) of the substrate 11 and forms a pattern, and the medium layer 12 includes a non-conductive section 121 having a plurality of blocks P (the blocks P are shown in fig. 1C). The electrical block P may be a conductive block, a conductive filament, a conductive sheet, a conductive ink, a conductive tape, a semiconductive material, or a combination thereof, and may include graphite, graphene, silver, copper, gold, aluminum, tungsten, or an alloy thereof, or a conductive metal oxide thereof. In a more ideal situation, the conductive blocks P in the non-conductive section 121 can be silver nanoparticle conductive blocks, so as to make the handheld circuit board 1 have better conductivity, or in other considerations, the conductive blocks P can also be different types of metals or non-metals, such as copper with lower cost or thinned graphene conductive blocks, as the conductive blocks P, so as to reduce the cost expenditure of the handheld circuit board 1 or make the handheld circuit board 1 thinner.

In this embodiment, the coating of the substrate 11 may be formed by a polymer coating, which can make the coating have better surface roughness. Because the substrate 11 has a coating with a better surface roughness, the manual circuit board 1 of the embodiment can facilitate a user to subsequently dispose the conductive material of the conductive ink pen 4 on the medium layer 12, and can make the circuit drawing and the circuit characteristics after the circuit drawing more stable. That is, by the design of the polymer coating, the conductive material of the conductive ink pen 4, such as silver paste, silver nanoparticles 41, etc., can be attached to the non-conductive section 121 of the medium layer 12, and will not fall off soon after attachment to affect the circuit stability of the handheld circuit board 1 (see fig. 1E). In addition, the substrate 11 in this embodiment is made of a photo paper with a better surface roughness. In another embodiment, the substrate 11 may not include a coating layer, and the medium layer 12 may be directly disposed on the substrate 11.

With continued reference to fig. 1A, the dielectric layer 12 in fig. 1A has a pattern of "y" shape, and therefore the electrical blocks P of the dielectric layer 12 are also defined by the dielectric layer 12 as the pattern of "y" shape, in other words, the handheld circuit board 1 of the present embodiment has circuit layout of "y" shape. Alternatively, in other embodiments, the medium layer 12 may be formed into a plurality of different patterns, such as polygons, concentric circles, spirals, stars, or irregularities, wherein the irregularities may be formed into more specific or preferred patterns, such as animals, fruits, stars, etc., to attract users of a shorter age and enhance the enjoyment of the use.

In practical applications, the conductive material, such as conductive ink, can be printed or transferred on the substrate 11 by a printing unit or a transfer printing unit to form a coating layer thereon, so as to form the medium layer 12 with the electrical blocks P. Generally, the conductive ink is water-based or alcohol-based, and comprises silver nanoparticles, a solvent (water or alcohol), a surfactant, a dispersion stabilizer, and other additives, and can be used to jet print the medium layer 12 with different patterns on the substrate 11 by digital ink-jet or 3D printing.

As shown in fig. 1A, the medium layer 12 and the non-conductive section 121 formed on the substrate 11 in the present embodiment are a light gray block. However, in other embodiments, the medium layer 12 may further include a plurality of sub-patterns, and at least some of the sub-patterns are not connected to each other. The sub-patterns may be, for example, dot, zebra or twill (see fig. 2A), dotted line, arrow or mosaic, so that the handheld circuit board 1 has a characteristic sub-pattern formed by the medium layer 12, which is more attractive to the user.

In fig. 1A, the battery 13 and the switch element 14 can be used as a control element set for controlling the manual circuit board 1 to be turned on and off, the battery 13 is disposed on the surface of the substrate 11, one end of the battery 13 is electrically connected to the medium layer 12, and the switch element 14 is electrically connected between the battery 13 and the medium layer 12. In practical application of the handheld circuit board 1 of the present embodiment, the battery 13 may be a button battery with a thinner thickness as a power source of the handheld circuit board 1, so as to further match the thinning of the handheld circuit board 1 and the substrate 11. In addition, the switch element 14 can be made of silver foil paper or copper foil paper folded by the user, not only using a metal switch, thereby increasing the user's sense of participation and creating the fun of DIY making the manual circuit board 1. After the silver paper and the copper paper are folded, the battery 13 and the medium layer 12 can be electrically connected by simply pressing the switch element 14.

In addition to the above elements, the handheld circuit board 1 further includes at least one electrochromic element 15, and the electrochromic element 15 is disposed on the substrate 11 and electrically connected to the medium layer 12. The electrochromic element 15 may include at least one of: for example, the light emitting unit, the heat generating unit, the sound generating unit, the electrochromic unit, the magnetic unit, or a combination thereof may be an LED, an electric heating sheet, a horn, a buzzer, a color changing sheet, an electromagnet, or a combination thereof, and the electrochromic element 15 may be energized to generate light, heat, sound, color change, magnetic force, or the like on the manual circuit board 1. The electrogenerated variable element 15 of the present embodiment uses two light emitting units, wherein the light emitting units are LEDs, and the two LEDs are connected in parallel to the "japanese" -shaped medium layer 12, when the electrical block P has electrical conductivity due to electrical connection, and the battery 13 and the switch element 14 are connected, the two LEDs can emit light, so that when the manual circuit board 1 of the present embodiment is used in combination with other construction components or teaching materials, the manual circuit board 1 can be directly used as a light emitting component of the construction components, for example, as a roof of an assembled house, and the roof (i.e., the manual circuit board 1) can emit light.

In addition, the electrochromic element 15 can be selected with the above mentioned media layer 12 according to the requirements of different teaching materials, for example, in other implementation manners, the electrochromic element 15 can also select a light emitting unit to match with a sound emitting unit, for example, an LED can be used with a speaker, so that the manual circuit board 1 can emit light and sound at the same time after the electrical blocks P are electrically connected, or a plurality of LEDs with different colors can be selected, so that the light emitted by the manual circuit board 1 is more colorful, and therefore, when the manual circuit board is used with other construction assemblies or teaching materials, the product satisfaction of users can be improved.

In practical applications of the manual circuit board 1 of the present embodiment, the dielectric layer 12 and the non-conductive section 121 included therein are equivalent to the circuit layout or circuit configuration of the manual circuit board 1, however, it should be noted that the electrical blocks P in the non-conductive section 121 are electrically connected only under specific conditions or conditions, so that the dielectric layer 12 has a conductive state, and the conductive state is related to the operation performed by the user.

Referring to fig. 1C and fig. 1D, the region a' of fig. 1C and the region a of fig. 1D have a plurality of electrical blocks P, and in the region a of fig. 1D, the electrical blocks P in the non-conductive section 121 occupy a lower distribution state in the non-conductive section 121. In addition, as shown in fig. 1D, the electrical blocks P are discontinuously distributed (zigzag) above the surface of the substrate 11, so that the electrical blocks P on the section line B-B of fig. 1A of the non-conductive section 121 are not electrically connected. In addition, the present embodiment is described with reference to the cross-sectional area a' of the cross-section formed by the areas a and B-B cross-sectional lines in fig. 1A, but the electrical blocks P also have substantially the same discontinuous distribution in other areas and different cross-sections of the non-conductive section 121 in fig. 1A, and are not limited to the areas a and B-B cross-sectional lines. In other words, when the electrical blocks P on the cross section of the non-conductive section 121 are not distributed continuously, the electrical blocks P will not be electrically connected. In short, the conductivity of the dielectric layer 12 is related to whether the electrical blocks P are continuously distributed on the cross section of the non-conductive section 121.

However, when the medium layer 12 is to be made conductive, a conductive layer may be disposed on the non-conductive section 121 of the present embodiment, such that the non-conductive section 121 is coated with the conductive layer, and the electric blocks P on the non-conductive section 121 are electrically connected to make the medium layer 12 conductive. The arrangement is as shown in fig. 1E, the user can draw a conductive layer on the medium layer 12 through the conductive ink pen 4 or the conductive mark pen. Since the conductive ink pen 4 contains the silver nanoparticles 41 or the silver paste ink, and in this embodiment, the silver nanoparticles 41 have the same material composition as the electrical block P, after the conductive layer or the silver nanoparticles 41 are drawn, the electrical block P can have a continuous distribution state on the cross section of the non-conductive section 121, and can be electrically connected, so that the dielectric layer 12 can have conductivity.

Referring to fig. 1F, fig. 1F shows a region a of the medium layer 12 after the conductive layer is drawn by the conductive ink pen 4, and a partially enlarged view thereof shows that the distribution state of the electrical blocks P in the non-conductive section 121 is significantly improved compared to fig. 1D. Meanwhile, as the distribution state of the electrical blocks P is increased, the electrical blocks P on the cross section are changed from the original discontinuous distribution state to the continuous distribution state, so that the electrical blocks P are electrically connected. In short, when the user applies the silver nanoparticles 41 on the electrical block P through the conductive ink pen 4 to fill the medium layer 12 after following the guidance of the medium layer 12, the electrical block P in fig. 1E can be electrically connected and has conductivity due to the continuous distribution state on the cross section of the non-conductive section 121, so that the manual circuit board 1 in fig. 1E can be conducted.

Therefore, the user can draw a circuit on the medium layer 12 by using the conductive ink pen 4 according to the guidance of the medium layer 12, so that the medium layer 12 has conductivity. In addition, the conductive ink pen 4 can draw different circuit distances according to the material of the substrate 11 and the writing speed of the user. The usable distance may also be different according to the surface roughness of the substrate 11, for example, the distance that the substrate 11 with poor surface roughness can be drawn is shorter, and the manual circuit board 1 of the embodiment may be drawn for a longer distance due to the design that the photo paper with better surface roughness is used as the substrate 11 and has a coating, so that the use efficiency of the conductive ink pen 4 can be greatly improved and the use time can be prolonged. In addition, the photo paper is used as the substrate 11, which can not only wipe and remove the circuit which is carelessly scratched, but also make the electrical block P have better conductivity.

It should be noted that, as shown in fig. 1A and 1E, the medium layer 12 of the present embodiment may include a conductive section 122 opposite to the non-conductive section 121 in addition to the non-conductive section 121, and the conductive section 122 may also be coated with a conductive layer by a user. The conductive segment 122 also includes a plurality of electrical blocks P, and the difference from the non-conductive segment 121 is that the electrical blocks P in the conductive segment 122 are distributed continuously, rather than discontinuously, so that the electrical blocks P on at least one cross section of the conductive segment 122 are electrically connected. Specifically, the conductive segment 122 is a low resistance region, and the conductive segment 122 can be autonomously controlled by a user according to different requirements. Moreover, due to the arrangement of the conductive section 122, the user can draw the conductive layer on the medium layer 12 through the conductive ink pen 4 or the conductive mark pen more smoothly, thereby preventing the medium layer 12 from being broken. Alternatively, in other embodiments, the non-conductive section 121 is a high resistance region, and the user can independently adjust and control the resistance of the non-conductive section 121 according to different requirements of the user. For example, the user can repeatedly use the conductive ink pen 4 or the conductive marker pen to form a conductive layer on the medium layer 12, so that the more densely the electrical blocks P are distributed, the resistance of the conductive section 122 is reduced. On the contrary, the user can reduce the number of times of repeatedly setting the conductive layer, so that the resistance value of the conductive section 122 is maintained at a higher level, thereby achieving the purpose that the user autonomously controls the resistance value of the conductive section or the non-conductive section and operates in the regulation and switching of the conduction or the non-conduction. In addition, the medium layer 12 of the handheld circuit board 1 of the present invention may include only the non-conductive section 121, the conductive section 122, or both the conductive section 122 and the non-conductive section 121, and the present invention is not limited thereto.

Thus, the manual circuit board 1 of the embodiment includes the substrate 11 and the medium layer 12, the medium layer 12 is disposed on a surface of the substrate 11 and forms a pattern, the medium layer 12 includes a non-conductive section 121 having a plurality of electrical blocks P, wherein the electrical blocks P in the non-conductive section 121 are discontinuously distributed, so that the electrical blocks P on at least one cross section of the non-conductive section 121 are not electrically connected. Alternatively, the medium layer 12 may include both the non-conductive section 121 and a conductive section 122 having a plurality of blocks P, wherein the blocks P in the conductive section 122 are continuously distributed, so that the blocks P on at least one cross section of the conductive section 122 are electrically connected. Moreover, since the substrate 11 has a coating with a better surface roughness, the hand-made circuit board 1 can easily dispose the silver nanoparticles 41 of the conductive ink pen 4 on the medium layer 12, so that the circuit drawing and the circuit characteristic after the circuit drawing are more stable. In addition, the user can draw a circuit on the medium layer 12 according to the guidance of the medium layer 12, so that the blocks P are continuously distributed and electrically connected. By means of the design of the medium layer 12, a general user who never contacts the circuit or the manual circuit board can arrange the circuit automatically according to the guidance of the medium layer 12 of the manual circuit board 1 to make the circuit conductive and DIY manufacture the desired manual circuit board, thereby achieving the purposes of reducing the manufacturing difficulty of the manual circuit board and enabling the user to intuitively and easily operate the manual circuit board without only needing to manufacture the manual circuit board through a professional, and improving the flexibility and the elasticity of manufacturing the manual circuit board. Meanwhile, the fun of drawing circuits and manufacturing manual circuit boards is improved.

In addition, the manual circuit board 1 of the present invention may have different media layer patterns and be used with the substrate 11 provided above.

Referring to fig. 2A and 2B, fig. 2A is a schematic diagram of another embodiment of a handheld circuit board according to the invention. Fig. 2B is a partially enlarged schematic view of the medium layer region B in fig. 2A.

The handheld circuit board 1a of fig. 2A has most of the same elements and element relationships as the handheld circuit board 1 of the previous embodiment. The handheld circuit board 1a of the present embodiment has a circuit layout in a shape of "ri" as in the handheld circuit board 1 of the previous embodiment, except that the medium layer 12a formed on the substrate 11 in the present embodiment is not shown in a light gray block, but is shown in a sub-pattern of a zebra stripe or a twill stripe by using the electrical blocks P. As shown in fig. 2B, the area B of fig. 2A also has a plurality of electrical blocks P, and the electrical blocks P can be arranged in the above-mentioned zebra or twill-shaped sub-pattern, and by means of the zebra or twill-shaped sub-pattern, a user can draw a circuit (i.e. coating silver nanoparticles 41 with conductive ink pen 4) on the medium layer 12A according to the guidance of the medium layer 12A, so that the area percentage of the electrical blocks P in the non-conductive section 121a is increased, and the electrical blocks P can be electrically connected and the medium layer 12A has conductivity because of having a continuous distribution state on the cross section of the non-conductive section 121 a.

Due to the design of the zebra or twill-shaped sub-patterns, the manual circuit board 1a of the present embodiment can generate a greater attraction for the user because the medium layer 12a has the sub-patterns with a distinctive style. In addition, in the present embodiment, the

electrochromic elements

15 and 15a respectively select a light emitting unit to match with a sound emitting unit, that is, an LED is used in combination with a speaker, so that after the medium layer 12a has conductivity, the manual circuit board 1a can emit light and sound at the same time, and the manual circuit board 1a can provide sound output in addition to light emission, thereby further improving the product satisfaction of users when used in combination with a constructed component or a teaching material.

In addition, other technical features of the manual circuit board 1a of the present embodiment can refer to the related description of the manual circuit board 1 of the previous embodiment, and are not described herein again.

In addition, the manual circuit board of the invention can also utilize the light-emitting unit which is manually operated by a user to be matched with the medium layer of the circuit board.

Referring to fig. 3A and 3B, fig. 3A is a schematic diagram of another embodiment of a handheld circuit board according to the invention. Fig. 3B is a schematic view of the electrical substrate disposed on the paper card in fig. 3A. Referring to fig. 3A and 3B together, the manual circuit board 1B of fig. 3A and the manual circuit board 1 of the previous embodiment have most of the same elements and relationships between the elements. Among them, the electrochromic element of the present embodiment is a light emitting unit 16. The difference from the aforementioned electrochromic element is that the light-emitting unit 16 in the manual circuit board 1b of the present embodiment is manually operated by the user.

Referring to fig. 3A, the light emitting unit 16 includes an electrical substrate 161, a light emitting diode 162 and a flexible patch 163. Specifically, the electrical substrate 161 has a similar electrical block structure as the medium layer 12, and when the user does not use the conductive ink pen 4 to coat the silver nanoparticles 41 or the conductive layer is not disposed on the electrical substrate 161, the electrical substrate 161 will not have conductivity. In addition, the base material of the electrical base material 161 may be selected from one of a wood base plate, a bamboo base plate, a paper base plate, a cotton base plate, a high-density fiber base plate, and a resin base plate, or a combination thereof. The electrical substrate 161 is made of a conductive material similar to the medium layer 12, and may include graphite, graphene, silver, copper, gold, aluminum, tungsten, or an alloy thereof, or a conductive metal oxide thereof, and the electrical substrate 161 is electrically connected to the medium layer 12.

In addition, the led 162 is electrically connected to the electrical substrate 161, and the flexible patch 163 can be flatly attached to or surround the electrical substrate 161 and the led 162, so that the electrical substrate 161 and the led 162 can be electrically connected and fixed to each other. In the embodiment, the flexible patch 163 is a tape for fixing the electrical substrate 161 and the light emitting diode 162, and in other embodiments, the electrical substrate 161 and the light emitting diode 162 may be a double-sided tape or a cloth.

As shown in fig. 3B, the electrical substrate 161 is pre-disposed in a paper card C, and on the paper card, the electrical substrates 161 at two sides can mark the positive terminal and the negative terminal. The paper card C may be provided with a plurality of sets of the electrical substrates 161, and the electrical substrates 161 between the sets may be spaced apart from each other by printing a dotted line through the paper card C. With the above design, the user can easily cut or tear one set of the electrical substrates 161 from the paper card C along the dotted line. In addition, in the embodiment, the paper card C is provided with four sets of the electrical substrates 161 as an example, and in other aspects, the paper card C may be provided with more or less sets of the electrical substrates 161. When the manual light emitting unit 16 is to be installed, the manual electrical substrate 161 is first contacted with the medium layer 12 in the circuit board 1b, the light emitting diode 162 is then installed between the two manual electrical substrates 161, the light emitting diode 162 is electrically connected to two ends (positive and negative) of the electrical substrate 161, and the light emitting diode 162 is then bonded or fixed to the electrical substrate 161 and the manual circuit board 1b by the flexible patch 163.

It should be noted that, during the manual operation of the electrical substrate 161, the user should cut off the excess paper card outside the electrical substrate 161 to facilitate the electrical substrate 161 to be electrically connected to the medium layer 12 in the circuit board 1 b. Moreover, the electrical substrate 161 may have a sub-pattern similar to the medium layer 12, for example, a sub-pattern in a zebra or twill shape may be used in addition to the light gray block. In the present embodiment, the hand-made electrical substrate 161 is also exemplified by a sub-pattern using a light gray block. By the guidance of the electrical substrate 161 and the medium layer 12 by the user, the area percentage of the electrical blocks P in the non-conductive section 121 and the electrical substrate 161 is increased by drawing the circuit arrangement conductive layer on the medium layer 12 and the electrical substrate 161, so that the electrical blocks P have a continuous distribution state on the cross section of the non-conductive section 121, and can be electrically connected, so that the medium layer 12 and the electrical substrate 161 are electrically conductive after contacting, and the manual light-emitting unit 16 can be conducted to emit light. Therefore, the light emitting diode 162 emits light through the electrical substrate 161 made by hand, so that the user can more increase the pleasure of installing the light emitting unit 16 and using the hand to make the circuit board 1 b.
