Description

Conductive rubber member package and method for supplying conductive rubber member

The present invention relates to an electrical component and a circuit board that are assembled inside an electronic device such as a mobile phone device or a digital camera, and are disposed between circuit boards, between a circuit board and an electronic component, or in an exterior member of the device. A mounting technique of a conductive rubber member that electrically connects between various components such as the other or between the electrodes of the electronic component.

It is known that a conductive rubber member is sandwiched and fixed between face-to-face circuit boards or between a circuit board and an electronic component, and is electrically connected between electrodes of the circuit board or between electrodes of the circuit board and the electronic component. . As an example of the related art, the conductive rubber member 1 which is the same as the anisotropic conductive connector disclosed in WO2010/082616 (Patent Document 1) is insulative as shown in Figs. 12 and 13 . The bottom surface of the elastic sheet 2 made of a rubber-like elastic body is formed with a metal plate 4, and the magnetic conductive body 3a is disposed in a direction in which the particle-shaped magnetic conductor 3a is oriented as a conductive medium in the height direction, and the conductive portion 3 is formed to have conductivity in the height direction of the elastic sheet 2. On the other hand, the anisotropy of conductivity is not exhibited in the planar direction of the elastic sheet 2.

In this case, the conductive rubber member is on a circuit substrate or an electron The mounting on the member or the like is performed by being placed on a solder-coated circuit board or an electronic component or the like, and then heated by a reflow furnace to be soldered and fixed to a circuit board, an electronic component, or the like. Since the conductive rubber member 1 has the conductive portion 3 and has a flat plate shape as a whole, it can be stably placed on a circuit board, an electronic member, or the like in such a mounting process.

However, for the purpose of reducing the installation space of the conductive rubber member or reducing the connection area of the circuit board or the like to be connected, it is desirable to provide a conductive rubber member having one conductive portion and having a small width in the planar direction. When the width in the planar direction is small, a conductive rubber member having an elongated columnar shape in the height direction (conduction direction or vertical direction) is formed, so that the conductive rubber member is likely to fall over and tilt in the mounting process. The settings you set are abnormal. Further, in order to mount the conductive rubber member on a circuit board or an electronic component or the like, it is also desirable to achieve automatic mounting by picking up the nozzle.

Therefore, an object of the present invention is to provide a technique capable of stably supplying a conductive rubber member during a process of attaching a conductive rubber member to a circuit board or the like via a pick-up and reflow soldering process.

The present invention provides a conductive rubber member package having a conductive rubber member and an embossed tape, and is placed in a receiving portion of the embossed tape Conductive rubber member. The conductive rubber member has a base portion made of an insulating rubber-like elastic body, a conductive portion formed of a magnetic conductor that is disposed in a bead-like direction through the base portion in the height direction, and a metal portion that is fixed to the bottom surface. And the connecting object members are electrically connected to each other by pressing contact between the connected connecting member members and via the conducting portion. The embossed tape includes a base film having a accommodating portion for accommodating the conductive rubber member, a cover film for closing the accommodating portion, and a bottom surface of the conductive rubber member on the inner bottom surface of the accommodating portion, thereby being A conductive rubber member is housed.

Since it has a conductive rubber member, it can be utilized as a connector for electrically connecting a conductor having a base portion made of an insulating rubber-like elastic body and penetrating the base portion in the height direction. The conductive portion formed by the magnetic conductors arranged in a beaded shape, the metal portion fixed to the bottom surface, and the contact member members are electrically connected to each other through the conductive portion between the conductive connecting member members.

Further, since the embossed tape is provided, the conductive rubber member can be protected and stored, and the embossed tape includes a base film having a accommodating portion for accommodating the conductive rubber member, and a cover film for closing the accommodating portion. The bottom surface of the conductive rubber member is placed on the inner bottom surface of the accommodating portion to accommodate the conductive rubber member. Further, a plurality of conductive rubber members as small members can be integrated and disposed. Further, by automatically carrying the embossed tape, it is possible to advance the process of picking up the conductive rubber member and loading the circuit board or the like.

In the conductive rubber member, the periphery of the conductive portion made of the magnetic conductor is made of an insulating rubber-like elastic body. Since the parts are covered, the conductive contact between the conductors can be reliably performed.

Further, in the embossed tape, since the base film having the accommodating portion is covered with the cover film, the conductive rubber member housed in the accommodating portion can be easily taken out by opening the cover film. Furthermore, it is also possible to form a roll so that even a long embossed tape can be compactly integrated.

The shape of the conductive rubber member may be an elongated shape in the height direction thereof. Since the conductive rubber member having an elongated shape in the height direction is accommodated in the accommodating portion of the embossed tape, it can be kept in an upright state, and can be picked up even in an elongate shape that is easy to fall over.

The shape of the conductive rubber member may be a shape that is tapered toward the upper side. Since the shape of the conductive rubber member is tapered toward the upper side, the center of gravity is lowered, so that it is easy to stabilize its posture on the inner bottom surface of the accommodating portion or the connecting member member.

It is possible to produce a conductive rubber member package in which the inner bottom surface shape of the embossed tape accommodating portion is a shape corresponding to the bottom surface of the conductive rubber member. Since the shape of the inner bottom surface of the embossed tape accommodating portion is a relative shape corresponding to the bottom surface of the conductive rubber member, the conductive rubber member is apt to be stably carried in the accommodating portion. Further, when the conductive rubber member is inserted into the accommodating portion, the conductive rubber member is easily accommodated by the accommodating portion.

It is possible to produce a conductive rubber member package in which the opening of the embossed tape accommodating portion is larger than the inner bottom surface of the accommodating portion. When the opening of the embossed tape accommodating portion is larger than the width of the inner bottom surface of the accommodating portion, when the conductive rubber member is inserted into the accommodating portion, the conductive rubber member is easily accommodated by the accommodating portion.

A projection may be provided at an angle of the inner bottom surface of the embossed tape receiving portion. Since the convex portion is provided at the corner of the inner bottom surface of the embossed tape accommodating portion, when the conductive rubber member is inserted into the accommodating portion, the corners of the conductive rubber member are less likely to touch the accommodating portion. One of the preferred shapes of the projection is an arc shape.

Further, the method of supplying the conductive rubber member that is taken out after the conductive rubber member accommodated in the embossed tape is taken out from the embossed tape, the method for supplying the conductive rubber member according to the present invention is characterized in that In the conductive rubber member package, a magnetic force is applied from the bottom surface side of the conductive rubber member, and the conductive rubber member is swung in the embossed tape accommodating portion, and then the top surface of the conductive rubber member is sucked by the suction nozzle, thereby further pressing The strip is taken out and supplied.

Since the magnetic force is applied from the bottom surface side of the conductive rubber member, the longitudinal direction of the conductive portion (the direction in which the magnetic conductors are arranged) is parallel with respect to the direction of the magnetic flux. As a result, the conductive rubber member that is placed obliquely in the accommodating portion of the embossed tape is rotated in the upright direction in the accommodating portion, thereby facilitating formation of the conductive rubber member carried on the inner bottom surface of the accommodating portion. The erect state of the bottom surface. Thereby, the conductive rubber member can be aligned in the accommodating portion. Subsequently, since the top surface of the conductive rubber member is sucked by the suction nozzle and taken out from the embossed tape, the suction nozzle can be brought closer to the conductive rubber member at a position suitable for adsorption, thereby making the conductive rubber in the mounting process. The setting of the member upset and skew setting is extremely difficult to occur. That is, by arranging the conductive rubber member in the accommodating portion, it is possible to reduce the adsorption error of the nozzle.

In the supply process of such a conductive rubber member, after the embossed tape is automatically conveyed and the conductive rubber member is passed over the magnet as the permanent magnet, the conductive rubber member can be adsorbed by the suction nozzle. By passing the conductive rubber member over the magnet, the conductive rubber member can be aligned, and then the magnetic force is weakened by moving away from the magnet, so that the suction of the nozzle can be facilitated.

Alternatively, when the embossed tape is automatically conveyed and the conductive rubber member is placed on the magnet as the permanent magnet, the conductive rubber member may be adsorbed by the suction nozzle. When the conductive rubber member is adsorbed on the magnet, the suction force of the nozzle is slightly increased. However, since the posture of the conductive rubber member can be surely ensured, the picking error can be reduced.

Further, the magnet may be an electromagnet, so that the application, the disappearance, and the strength of the magnetic force can be appropriately adjusted. Since an electromagnet can be used to adjust the presence or absence of a magnetic force, after the conductive rubber member is swung, for example, de-energization can be performed to make the magnetic force disappear, thereby making the suction of the nozzle easy, or the positive conductivity. The rubber member adopts a strong magnetic force, and various operations for keeping it in a positive state under a weak magnetic force at the time of picking up.

Further, the conductive rubber member is housed in the embossed tape, whereby a conductive rubber member package can be obtained. Further, the embossed tape houses the conductive rubber member, whereby a conductive rubber member package can be obtained.

According to the conductive rubber member package and the method for supplying the conductive rubber member of the present invention, the conductive rubber member is mounted In the middle, it is possible to make the picking up of the nozzle difficult to occur.

Hereinafter, the present invention will be further described in detail based on the embodiments. The configurations that are common to the following embodiments are denoted by the same reference numerals, and the description thereof will not be repeated. In addition, the description of the common materials, manufacturing methods, effects, and the like will be omitted.

First embodiment

As shown in FIG. 1, the conductive rubber member package 10 of the present embodiment is formed by accommodating the conductive rubber member 20 in the embossed tape 30 and forming the conductive rubber member 20 and the embossed tape 30 as a packaging material. One product.

As shown in FIG. 2 and FIG. 3, the conductive rubber member 20 includes a base portion 21 made of an insulating rubber-like elastic body, and the base portion 21 is in the height direction by a magnetic conductor 22a arranged in a bead shape in the height direction. The conductive portion 22 that penetrates and the metal portion 23 that is fixed to the bottom surface 20a are formed.

The base portion 21 is formed of an insulating rubber-like elastic body and wraps around the conduction portion 22 of the substantially central region thereof. The base portion 21 shown in Fig. 2 has a quadrangular frustum-shaped base portion 21a having a slightly larger width on the bottom surface 20a side, and has a quadrangular frustum-shaped inclined tube portion which is tapered upward on the upper side of the base portion 21a. 21b.

The hardness of the base portion 21 is preferably JIS K6253 A10-A80. If the hardness is less than A10, the compression set becomes large and the physical strength is also weak, which may make the conduction performance after mounting unstable. If the hardness is greater than A80, the compression load becomes large. As the material of the base portion 21, an insulating rubber-like elasticity obtained by curing a liquid rubber can be used. The body or the insulating rubbery elastomer that can be heated and melted. Examples of the liquid rubber include ruthenium rubber, natural rubber, isoprene rubber, butadiene rubber, acrylonitrile butadiene rubber, 1,2-polybutadiene, styrene butadiene rubber, chloroprene rubber, and butyl. Nitrile rubber, butyl rubber, ethylene propylene rubber, chlorosulfonated rubber, polyethylene rubber, acrylic rubber, epichlorohydrin rubber, fluororubber, urethane rubber, etc. Examples of the rubber-like elastomer that can be heated and melted include a styrene-based thermoplastic elastomer, an olefin-based thermoplastic elastomer, an ester-based thermoplastic elastomer, a polyurethane-based thermoplastic elastomer, an amide-based thermoplastic elastomer, and a vinyl chloride-based thermoplastic elastomer. Body, fluoride-based thermoplastic elastomer, ion-crosslinked thermoplastic elastomer, and the like. From the viewpoint of moldability, electrical insulation, and weather resistance, it is preferred to use a liquid ruthenium rubber. The viscosity of the liquid rubber or the melting of the heating should be such that the contained magnetic conductor 22a can move in a magnetic field, preferably 1 Pa. s-250Pa. s, more preferably 10Pa. s-100Pa. s.

In the conduction portion 22, the particulate magnetic conductors 22a are formed by being oriented in a bead shape in accordance with the magnetic field orientation described later. The distal end of the conductive portion 22 is exposed from the surface of the electrical rubber member 20, and the lower end is in conductive contact with the metal portion 23.

As the material of the magnetic conductor 22a constituting the conduction portion 22, particles exhibiting ferromagnetism and having conductivity can be used. For example, a ferromagnetic metal such as nickel, cobalt or iron or alloy particles containing the same may be mentioned. In addition, particles in which a ferromagnetic metal such as nickel, cobalt, iron, or ferrite is coated with a metal having excellent conductivity, and a surface of the conductive or insulating particles may be made of nickel, cobalt, iron, or the like. Wrapped particles. Among them, the preferred one is to use A ferromagnetic body is a metal-coated particle having excellent electrical conductivity. As the metal having excellent conductivity, metals such as gold, silver, platinum, aluminum, copper, palladium, and chromium, or alloys such as stainless steel may be used.

The metal portion 23 is fixed to the bottom surface 20a in a size corresponding to the shape of the periphery of the base portion 21a, and is in conductive contact with the lower end of the conduction portion 22.

The metal portion 22 is formed of a conductive metal foil, and examples of the material thereof include copper, silver, gold, platinum, nickel, titanium, chromium, aluminum, and the like. The metal portion 22 may have a thickness of 5 μm to 400 μm. If it is thinner than 5 μm, the workability is deteriorated, so that it is difficult to fix it to the bottom surface 20a. Moreover, if it is thicker than 400 μm, the price becomes expensive.

The metal portion 23 may be formed by forming a film made of the above-described metal by a vapor deposition method, an ion plating method, a sputtering method, or the like, in addition to the metal foil.

Although the overall shape of the conductive rubber member 20 mainly depends on the outer shape of the base portion 21, it is preferable that the bottom surface 20a and the top surface 20b are horizontal. The bottom surface 20a is horizontally formed so that the conductive rubber member 20 is aligned in the accommodating portion 31a, and the top surface 20b is horizontally formed in order to facilitate the suction of the nozzle, thereby avoiding pick-up and omission. Further, since the width of the upper portion is narrowed, the problem that the wall surface of the accommodating portion 31a comes into contact with the side surface of the conductive rubber member 20 is prevented from being too tight.

In the production of the conductive rubber member 20, first, a mold for molding is prepared. The mold is formed of a non-magnetic body, and is embedded with a positioning pin for forming the conduction portion 22 and composed of a ferromagnetic body. One end of the locating pin The cavity surface at the position where the conduction portion 22 is formed is exposed. A liquid rubber mixed with a magnetic conductor is injected into the mold, followed by application of a magnetic force. At this time, the magnetic conductors are gathered at the portion sandwiched by the positioning pins, so that the magnetic conductors are arranged in a beaded orientation between the positioning pins. Subsequently, the liquid rubber is solidified to obtain a structure having the conduction portion 22 in the base portion 21. Finally, the metal portion 23 made of a metal thin film is fixed to the bottom surface of the base portion 21 and the conductive portion 22 with a conductive adhesive to obtain the conductive rubber member 20.

Further, instead of fixing with a conductive adhesive, the metal portion 23 may be disposed in advance in the mold to be integrally formed with the base portion 21 or the conductive portion 22.

As shown in FIGS. 4 and 5, the embossed tape 30 includes a base film 31 having a accommodating portion 31a for accommodating the conductive rubber member 20, and a cover film 32 for closing the accommodating portion 31a. Further, the guide holes 33 for conveyance are provided at regular intervals, so that the embossed tape 30 can be automatically conveyed.

The accommodating portion 31a is a recessed portion that is disposed at an appropriate interval in the longitudinal direction of the base film 31, and is formed to carry the bottom surface 20a of the conductive rubber member 20 on the inner bottom surface 31b of the accommodating portion 31a, and can accommodate the conductive portion. The size of the rubber member 20. In other words, when the depth of the accommodating portion 31a is substantially equal to the height of the conductive rubber member 20, the conductive rubber member 20 is easily aligned when the accommodating portion 31a is covered with the cover film 31, and the electric rubber member is placed during transportation or the like. 20 is not easy to fall over in the accommodating portion 31a.

Further, in the shape of the accommodating portion 31a, the space of the concave portion in FIG. 4 and FIG. 5 has a rectangular parallelepiped shape, but the opening width of the concave portion is slightly larger than the width of the inner surface 31b of the concave portion. Conductivity due to large opening width The rubber member 20 easily enters the accommodating portion 31a, and since the inner bottom surface 31b is narrower than the opening width, it is easy to accommodate the conductive rubber member 20 in the accommodating portion 31a.

The shape of the inner bottom surface 31b of the accommodating portion 31a is substantially the same shape (relative shape) as the bottom surface 20a of the conductive rubber member 20, but it is preferable that the inner bottom surface 31b of the accommodating portion 31a is formed with a gap. The extent is greater than the bottom surface 20a of the conductive rubber member 20. Thereby, it is easy to align the conductive rubber member 20 in the accommodating portion 31a.

Further, since the inner bottom surface 31b of the accommodating portion 31a has a rectangular shape and the bottom surface 20a of the conductive rubber member 20 has a rectangular parallel shape, when the conductive rubber member 20 is slanted in the accommodating portion 31a, The bottom surface 20a of the conductive rubber member 20 can be aligned with the orientation of the inner bottom surface 31b of the accommodating portion 31a. Thus, when the automatic mounting of the conductive rubber member 20 by the nozzle is performed, the orientation of the bottom surface 20a of the conductive rubber member 20 supplied to the circuit board can be easily controlled to match.

The base film 31 can be obtained by molding a resin film having a shape, and it is preferable to use an antistatic resin containing an appropriate degree of carbon and having low electrostatic properties as a raw material. Examples of such a resin include polyethylene (PS), polycarbonate (PC), polyethylene terephthalate (PET), and polypropylene (PP).

The cover film 32 is a member that closes the accommodating portion 31 and prevents the conductive rubber member 20 housed in the accommodating portion 31 from coming off. The cover film 32 is peeled off from the base film 31 when the conductive rubber member 20 is picked up, and thus it is preferable that A thin and flexible resin film. Examples of such a resin include polyethylene (PS), polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), and polyvinyl chloride (PVC).

In addition, for the purpose of confirming the case where the conductive rubber member 20 is placed in the housing portion 21a, it is preferable to use a film having high transparency.

When the conductive rubber member package 10 is manufactured, the conductive rubber member 20 is placed one by one in such a manner that the bottom surface 20a of the conductive rubber member 20 is carried on the inner bottom surface 31b of the accommodating portion 31a of the base film 31, and then the surface thereof is placed. The cover film 32 is covered and fixed on the base film 31. Thereby, the conductive rubber member package 10 in which the conductive rubber member 20 is housed in the embossed tape 30 can be obtained.

The conductive rubber member package 10 is formed into a roll shape after being covered with the cover film 32, so that storage can be facilitated. Further, as shown in FIG. 6, it may be provided on the take-up roller to achieve automatic conveyance.

When the conductive rubber member 20 is mounted on a circuit board, it can be carried out as follows.

The embossed tape 30 is taken out from the roll from the roll-shaped conductive rubber member package 10 with the cover film 32 facing upward, and the cover film 31 is peeled off. Subsequently, as shown in FIG. 7, the accommodating portion 31a is placed on the magnet M, and the magnetic force mf is applied from the side of the bottom surface 20a of the conductive rubber member 20. At this time, for example, as shown in FIG. 8, the conductive rubber member 20 which is inclined in the accommodating portion 31a can attract the metal portion 23 to the inner bottom surface 31b due to the magnetic force, so that it can be accommodated in the accommodating portion as shown in FIG. Aligning conductive rubber in 31a Member 20.

Then, the top surface 20b of the conductive rubber member 20 is sucked by the suction nozzle, and the conductive rubber member 20 is sucked on the suction nozzle, and then the take-out operation (not shown) is performed from the accommodating portion 31a. Subsequently, it is supplied onto the solder which has been previously applied onto the substrate circuit, and the conductive rubber member 20 mounted on the circuit board is obtained by passing it through a reflow furnace.

Modification of embodiment

(conductive rubber member)

The conductive rubber member 20 has a shape in which the base portion 21a having a quadrangular shape on the bottom surface and a quadrangular pyramid shape, and the inclined tubular portion 21b having a quadrangular frustum shape connected thereto, but the shape thereof can be appropriately changed.

For example, the shape of the abutment portion may be a truncated cone shape having a circular bottom surface or a truncated cone shape having a polygonal bottom surface, and conversely, the oblique cylindrical portion may be a truncated cone shape or a truncated cone shape other than the four corners. . Alternatively, both may be in the shape of a truncated cone or a truncated cone. In the case of the conductive rubber member 20 having a truncated cone shape, the bottom surface 20a does not have directivity in the orientation. Therefore, when the automatic mounting by the nozzle is performed, the orientation of the bottom surface 20a of the conductive rubber member 20 can be ignored. Supply to the board.

The shape of the conductive rubber member 20 may be formed only of an inclined cylindrical portion having a top thin shape that is tapered toward the upper side and having no base portion, and may be, for example, a truncated cone shape or a truncated cone shape. . By adopting such a shape, the conductive rubber member can be made finer It is long so that it can also be applied to a narrower part of the board.

Further, it is possible to adopt a columnar or angular column shape which is not uniform in thickness at the top and which is equal in thickness in the height direction. If it is cylindrical or angular, the molding becomes easy.

(embossed tape)

As shown in FIG. 10, the accommodating portion 31a of the embossed tape 30 can have a base corresponding to the shape of the outer peripheral wall of the base portion 21a corresponding to the base portion 21a provided on the conductive rubber member 20. The receiving portion 31d is provided on the inner bottom surface 31b side (bottom side) of the accommodating portion 31a. By providing such a base receiving portion 31d, the conductive rubber member 20 can be easily aligned in the accommodating portion 31a.

Further, as shown in FIG. 11, an arc-shaped projection 31c can be formed at the corner of the inner bottom surface 31b of the accommodating portion 31a. Since the convex portion 31c is provided on the inner bottom surface 31b of the accommodating portion 31a, when the conductive rubber member 20 is placed in the accommodating portion 31a, the corner of the bottom surface of the conductive rubber member 20 is less likely to be touched, thereby facilitating the pendulum. Positive conductive rubber member.

(magnet)

As the magnet to which the magnetic force is applied, a permanent magnet such as a neodymium magnet can be used. A stable magnetic force can be provided by using a permanent magnet. On the other hand, an electromagnet can also be used. By using an electromagnet, the presence or absence of the magnetic field and the strength can be adjusted, and the pickup of the conductive rubber member 20 by the nozzle can be facilitated.

(Method of supplying conductive rubber member)

The supply of the conductive rubber member can also be variously changed. For example, in terms of adsorption using a nozzle, the magnetic field of the magnet can be positive It is carried out when it reaches the conductive rubber member; if it is after the magnetic field is applied, it can be carried out without the magnetic field being affected. In the former case, since the magnetically driven conductive rubber member is in a pendulum state, the approach of the nozzle can make it difficult to tilt, and it is necessary to resist the magnetic force to perform the adsorption, so that the adsorption force required for pickup becomes large. On the other hand, in the latter case, since the magnetic force is not applied, a small adsorption force can be used. However, since the magnetic force is not used for the square, the conductive rubber member is easily inclined when vibration or impact is applied.

It is also possible to supply the conductive rubber member in a state where the embossed tape is slightly inclined. When the embossed tape is inclined, the conductive rubber member is easily inclined by gravity, but when the magnet is placed so that the magnetic force is parallel to the conductive portion, the bottom surface of the conductive rubber member can be pressed to the inner side of the accommodating portion by the magnetic force. Bottom surface. Therefore, it is also possible to adsorb the conductive rubber member by tilting the nozzle. As described above, the picking up process of the conductive rubber member can be made three-dimensional, and the space saving of the working space can be achieved.

Example

The conductive rubber member was produced, and the height of the base portion was 0.3 mm, the overall height was 5.0 mm, the diameter of the conduction portion was 1 mm, the diameter of the top surface was 2 mm, the diameter of the bottom surface was 2.5 mm, and the material of the base was 矽. The material of the rubber or the magnetic conductor is nickel particles, and the conductive rubber member is housed in the embossed tape having the accommodating portion having the gap after the conductive rubber member is housed. The base film of the embossed tape was made of a conductive polyethylene resin and had a thickness of 400 μm. A neodymium magnet having a surface magnetic flux of 1000 G to 5000 G is placed at a position 2 mm from the bottom of the accommodating portion, and is used from the top surface of the conductive rubber member. The nozzle having an inner diameter of 1 mm was attracted to the nozzle at a suction amount of at most 5 L/min for 0.1 second to adsorb the conductive rubber member. When the adsorption test was carried out 10 times, the conductive rubber members were properly adsorbed on the nozzles in 10 times.

The shapes, materials, and the like of the respective portions described in the above-described embodiments and examples can be appropriately changed without departing from the scope of the invention. For example, known materials other than the above may be used, and these modifications are also included in Within the scope of the technical idea of the present invention.
