Description

  The present invention manufactures an electric wire composite printed wiring board including an electric wire component having terminals extended from a resin sealing portion and connected to a wiring pattern of the wiring board via a conduction hole conductor, and such an electric wire composite printed wiring board. Electric wire composite printed wiring board manufacturing method, electric wire component applied to such electric wire composite printed wiring board, electric wire component manufacturing method for manufacturing such electric wire part, and electronic device equipped with such electric wire composite printed wiring board About.

  In electronic devices that support high-frequency wireless signals such as mobile phones, wire components that can be electromagnetically shielded and compatible with high frequency by wiring three-dimensionally between printed circuit boards in order to reduce size and weight and achieve high-density mounting. The application of has increased.

  Conventionally, an electric wire component having a connector such as an electric wire with a connector, a coaxial electric wire with a connector, or a flexible substrate with a connector has been applied to the connection between the printed board and the printed board. In addition, as a device to which a connector is not applied, a flexible rigid multilayer printed wiring board in which a flexible substrate and a rigid substrate are combined is used.

  FIG. 21 is an explanatory view of a flexible rigid multilayer printed wiring board according to Conventional Example 1, (A) is a plan view, and (B) is an end view showing an end face of a cross section taken along arrows BB of (A). It is. It should be noted that hatching in the cross section is omitted in view of easy viewing of the drawing.

  The flexible rigid multilayer printed wiring board 101 according to Conventional Example 1 manufactured as a four-layer structure is manufactured generally by the following process.

  First, a double-sided flexible substrate (first insulating base 110 and first conductor layer 115) as an inner layer substrate is prepared, and an inner layer pattern (first conductor layer pattern 115p) is formed. That is, the first conductor layer pattern 115p is formed on the first insulating base 110. The first conductor layer pattern 115p is configured as a flexible lead pattern 115pf in the flexible region Af.

  Next, a film coverlay is pressure-bonded to the surface of the first conductor layer pattern 115p. That is, the protective insulating film (film cover lay) 130 (the protective film 131 and the protective adhesive 132) is formed.

  Further, a copper foil with resin from which a portion corresponding to the flexible region Af is removed as an outer layer substrate is prepared, and the inner layer substrate and the outer layer substrate are laminated and laminated (adhered). That is, the second insulating base 140 and the second conductor layer 141 are stacked and formed.

  In some cases, a single-sided rigid board from which a portion corresponding to the flexible region Af is removed as an outer layer board instead of the resin-coated copper foil may be prepared. At this time, an adhesive member corresponding to the single-sided rigid substrate is prepared, and the single-sided rigid substrate, the adhesive member, the double-sided flexible substrate, the adhesive member, and the single-sided rigid substrate are superposed in order and stacked and stacked.

  After the second insulating substrate 140 and the second conductor layer 141 are formed, a conduction hole 143 that conducts the second conductor layer 141 and the first conductor layer pattern 115p is opened. Thereafter, the whole is plated with copper to form a conductive hole conductor 144, and the second conductor layer 141 and the first conductor layer pattern 115p are connected.

  Next, the conduction hole conductor 144 and the second conductor layer 141 are patterned to form an outer layer pattern. That is, the second conductor layer pattern 145 is formed. Further, a solder resist 150 is formed and an appropriate surface treatment is performed.

  Thereafter, the outer shape of the flexible region Af and the outer shape of the rigid region Ar are formed.

  Inspection of the flexible rigid multilayer printed wiring board 101 whose outer shape is completed is performed.

  As described above, the flexible rigid multilayer printed wiring board 101 according to Conventional Example 1 uses a flexible substrate as the entire inner substrate.

  Many components are mounted in the rigid region Ar of the flexible rigid multilayer printed wiring board 101. That is, there are many circuit wirings (second conductor layer pattern 145), conduction holes 143, etc., high smoothing accuracy (for example, surface unevenness), high connection performance (for example, roughness of the inner wall of the conduction hole. The smaller the value, the smaller the metal fatigue of the through hole conductor due to temperature shock and the higher the reliability. Further, high electrical performance (for example, conduction resistance, insulation resistance), high heat resistance (for example, solder melting heat resistance), and the like are also required.

  That is, in the rigid region Ar, the conductor is preferably a material having a certain thickness, and the insulator is preferably a material having a certain hardness and a certain insulating property, and is preferably a homogeneous material. Therefore, in general, an epoxy resin containing glass fiber is often used.

  Further, the flexible region Af of the flexible rigid multilayer printed wiring board 101 has many circuit wirings (flexible lead patterns 115pf) functioning as lead wires, and high bending performance (for example, assembly bending, open / close bending) is required.

  That is, in the flexible region Af, it is preferable that the conductor is a material that can be processed to a certain thickness and has a certain flexibility, and the insulator is a material that has a certain flexibility. Therefore, in general, a polyimide resin film excellent in flexibility and insulation is often used.

  However, since the flexible rigid multilayer printed wiring board 101 according to Conventional Example 1 uses a flexible substrate as an inner layer substrate, the insulator is a rigid insulating base (second insulating base 140) in the rigid region Ar. Since it is formed as a composite material of a flexible insulating base material (first insulating base material 110), there is a problem that lamination processing is difficult.

  Further, since the rigid region Ar is formed of a composite material, there is a problem that it is difficult to open the conduction hole 143 and plating for forming the conduction hole conductor is difficult. Since a rigid insulating base (for example, a polyimide resin film) is included in the rigid region Ar, there is a problem that the hygroscopic property is high and the heat resistance performance is inferior.

  Further, it is difficult to adjust the thickness of the conductor (second conductor layer 141) in the rigid region Ar and the conductor (first conductor layer 115) in the flexible region Af, and the material of the conductor in the rigid region Ar and the conductor in the flexible region Af is difficult. There is a problem that it is difficult to optimize.

  In other words, the laminated structure characteristics required for each of the flexible region Af and the rigid region Ar (rigidity in the rigid region, flexibility in the flexible region, processability and reliability of the laminated structure, conductor layer properties, rigid region and There is a problem that it is difficult to satisfy the bonding strength between the flexible regions.

  In addition, the technique which applies a different insulating base material to a rigid area | region and a flexible area | region is proposed (for example, refer patent document 1).

  However, in the technique described in Patent Document 1, since the inner layer pattern (first layer conductor pattern) is formed separately in the rigid region and the flexible region, it is difficult to align the inner layer pattern with high accuracy and miniaturization. There is a problem that it is difficult to increase the density. In addition, since a flexible substrate is used, impedance matching is difficult, and if a shield layer is provided, there is a problem that the substrate becomes hard and bending becomes difficult, and bending performance is lowered.

  Next, the application status of conventional electric wire components will be described with reference to FIGS.

  22A and 22B are explanatory diagrams for explaining a printed circuit board according to Conventional Example 2. FIG. 22A is a plan view, FIG. 22B is a side view taken along arrow B in FIG. It is a side view in the state where electric wire parts were bent according to arrow mark Rot.

  The printed circuit boards 210 are connected to each other by an electric wire component 220 to form a printed circuit board unit (assembled printed circuit board unit). The electric wire component 220 includes a connector-equipped electric wire provided with a connector 225 and a connector-equipped coaxial electric wire.

  23A and 23B are explanatory diagrams for explaining a printed circuit board according to Conventional Example 3. FIG. 23A is a plan view, FIG. 23B is a side view taken along arrow B in FIG. It is a side view in the state where electric wire parts were bent according to arrow mark Rot.

  A printed circuit board unit (assembled printed circuit board unit) is formed by connecting the printed circuit boards 310 to each other with an electric wire component 320. The electric wire component 320 is constituted by a flexible substrate with a connector provided with a connector 325.

  24A and 24B are explanatory diagrams for explaining a printed circuit board according to Conventional Example 4. FIG. 24A is a plan view, FIG. 24B is a side view taken along arrow B in FIG. It is a side view in the state where electric wire parts were bent according to arrow mark Rot.

  A printed circuit board unit (assembled printed circuit board unit) is formed by connecting the printed circuit boards 410 to each other with a wire component 420. The printed circuit board 410 is formed of a rigid printed circuit board (rigid portion). ). That is, the printed circuit board unit is composed of a flexible rigid multilayer printed wiring board.

  When connecting with a connector-attached cable, a connector-equipped coaxial cable (conventional example 2), or a connector-equipped flexible board (conventional example 3), the electrical connection is made by contact of the connector, so the electrical connection becomes unstable. Therefore, there was a problem in reliability. Further, since the connectors are mechanically fitted and connected, there is a problem that the connection strength becomes unstable. Furthermore, since the connector is mounted on the printed circuit board, an occupied area is required on the printed circuit board, so that the surface area of the printed circuit board cannot be fully utilized.

  When connecting with a flexible board with a connector or a flex part of a rigid rigid multilayer printed wiring board (conventional example 4), variations in pattern width and pattern spacing occur due to the etching process that forms the flexible board. There was a problem that became unstable. Further, since the entire periphery of the signal pattern cannot be surrounded by the shielding pattern structurally, unnecessary radiation cannot be blocked, and there is a problem in electromagnetic shielding performance. Moreover, since the inner layer structure of the rigid part and the structure of the flex part are formed of an integral conductor or insulator, there is a problem that the electrical performance and mechanical performance at the flex part cannot be given the highest priority. Further, since the connection is made by a planar flexible member, there is a problem that the arrangement by the parallel movement or the arrangement by the torsion movement cannot be performed.

In addition, although the technique which incorporated the coaxial cable as an electric wire component in a wiring board is proposed (for example, refer patent document 2, patent document 3), it does not connect between wiring boards with an electric wire, but mentioned above. It does not solve the problem.

The present invention is applied to an electric wire composite printed wiring board 1 (see Embodiment 2 and FIG. 18) provided with an electric wire component 30 (see FIGS. 5A and 5B) having a resin sealing portion 39 (see FIGS. 4A to 4D). .

  FIG. 1 is a flowchart showing a schematic process flow of a wire component manufacturing method for manufacturing a wire component according to Embodiment 1 of the present invention.

  Hereinafter, although each process (S1 thru | or S4) is demonstrated, FIG. 2A thru | or FIG. 5B corresponding to each process is also demonstrated collectively.

Step S1:
2A and 2B are explanatory views schematically showing the structure of the electric wire provided in the electric wire component according to Embodiment 1 of the present invention, in which (A) is a front view and (B) is a side view showing the tip side, respectively. FIG.

  The electric wire 31 which comprises the electric wire component 30 is prepared (electric wire preparation process).

  The electric wire 31 has a conductor 31c constituting a signal line and a covering portion 31h that insulates and covers the conductor 31c. The electric wire 31 is preferably a coaxial cable (coaxial electric wire) further including an outer conductor 31s disposed on the outer periphery of the sheath 31h and an outer sheath 31f that insulates and coats the outer conductor 31s.

  The outer covering portion 31f, the outer conducting wire 31s, and the covering portion 31h are sequentially removed at the tip of the electric wire 31, and the end portion of the conducting wire 31c is exposed to prepare the electric wire 31. In addition, in the electric wire preparation process, the outer covering portion 31f is further removed to expose the end portion of the outer conductive wire 31s. Further, the outer conductive wire 31s is partially removed to expose the end portion of the covering portion 31h. The outer conducting wire 31s can be applied as a signal line or a shielding line.

  The electric wire 31 shown in FIG. 2A is a coaxial electric wire in which the conducting wire 31c is a single wire, and the outer conducting wire 31s arranged coaxially and insulated from the conducting wire 31c by the covering portion 31h is a braided wire. By configuring the outer conductor 31s with a braided wire, the flexibility of the electric wire 31 can be ensured.

  Since the electric wire 31 shown in FIG. 2B is basically the same as the electric wire 31 shown in FIG. 2A, different points will be mainly described. This is a coaxial electric wire in which the conducting wire 31c is a braided wire. In addition to the outer conductor 31s, the conductor 31c is also formed of a braided wire, whereby the flexibility of the electric wire 31 can be further improved.

  In addition, in the electric wire 31 shown in FIG. 2B, the conducting wire 31c is formed of a braided wire that is disposed around the insulating core material 31b and has a cylindrical shape. With this configuration, the shape of the braided wire constituting the conducting wire 31c can be held in a cylindrical shape, and the electric wire 31 can be secured with flexibility and formability.

  Since the conducting wire 31c is a signal wire, it is preferable that the conducting resistance is low, that the conducting wire 31c is flexible, and that the conducting wire 31c is not easily deteriorated. For example, a copper or copper alloy that is tin-plated can be used. As described above, either a single wire or a braided wire may be used.

  The covering portion 31h preferably has heat resistance, low hygroscopicity, flexibility, and excellent electrical characteristics (insulating properties). For example, a fluorine resin or the like can be applied.

  The outer conductor 31s preferably has a low conduction resistance, is flexible, and is hardly deteriorated. For example, a copper or copper alloy that is tin-plated can be used. Moreover, it becomes possible to further improve a softness | flexibility and an intensity | strength compared with a normal strand wire by comprising the outer side conducting wire 31s with a braided wire.

  The outer covering portion 31f, like the covering portion 31h, preferably has heat resistance, low hygroscopicity, flexibility, and excellent electrical characteristics (insulating properties). For example, a fluorine resin or the like can be applied.

  It is preferable to form the coaxial electric wire 31 so that air does not remain inside. For example, it is preferable to fill a gap between the lead wire 31c and the outer lead wire 31s with the covering portion 31h and the outer covering portion 31f.

  The conducting wire 31c and the outer conducting wire 31s can be applied to a linear body (or a strip-like body) in which a linear conductor is formed by vapor deposition or plating instead of the metal wire itself.

Step S2:
FIG. 3A is an explanatory view schematically showing an example as an intermediate product of the electric wire component according to Embodiment 1 of the present invention, where (A) is a plan view, (B) is a front view, and (C) is a front view. It is a side view which shows the front end side. 3B is an explanatory view showing an embodiment of an extension terminal for conducting wire in the intermediate product of the electric wire part shown in FIG. 3A, (A) is an exploded perspective view, and (B) is a connection of the extension terminal for conducting wire to the conducting wire. It is a perspective view which shows the state which carried out.

  The conductor extension terminal 32 is connected to the prepared electric wire 31 (conductor 31c) (conductor extension terminal connecting step). The electric wire 31 will be described by applying, for example, the one shown in FIG. 2B (the same applies below).

  The conducting wire 31c is connected to the conducting wire extension terminal 32 having a conducting wire extension plate portion 32f extending from the resin sealing portion 39 (see FIGS. 4A to 4D) and facing the first conductor layer pattern 12p. The conducting wire extension terminal 32 includes a conducting wire extension plate portion 32f and a conducting wire connection portion 32c which are connected to each other. In this embodiment, the conductive wire extension plate portion 32f and the conductive wire connection portion 32c are integrally formed by sheet metal processing. The conductor connecting portion 32c is bent in the direction of the arrow Fc (FIG. 3B (A)) and sandwiches the electric wire 31 (conductor 31c). Therefore, the extension terminal 32 for conducting wire is connected to the conducting wire 31c by the connection part 32c for conducting wire.

  The conductive wire extension plate portion 32f is connected to the first conductor layer pattern 12p via a conduction hole conductor 41 (see FIG. 14) formed in the interlayer conduction hole 40 (see FIG. 13) of the second insulating base material 21. It has a connection hole 32h. The conductive wire extension plate 32f is also connected to the second conductor layer pattern 22p by the conduction hole conductor 41 (see FIG. 14).

  The electric wire component 30 includes a conductive wire extension plate portion 32f laminated in a planar manner facing the first conductor layer pattern 12p, and the conductive wire extension plate portion 32f is highly accurate with respect to the first conductor layer pattern 12p. It has a connection hole 32h that can be aligned. Therefore, the electric wire component 30 can be applied to the electric wire composite printed wiring board 1 and can easily and firmly connect the conductive wire 31c to the first layer conductor layer pattern 12p (first wiring board 10).

  In the conductor extension terminal connection step, the outer conductor intersection terminal 35 and the outer conductor 31s can be connected together. The outer conducting wire 31 s is connected to the outer conducting wire intersecting terminal 35 having the outer conducting wire intersecting end portion 35 p that is arranged to be exposed on the surface of the resin sealing portion 39 so as to intersect the electric wire 31. The outer conductor crossing end 35p is configured to be connected to the second conductor layer pattern 22p via a conduction hole conductor 41 formed in the interlayer conduction hole 40 of the second insulating base 21 (see FIG. 15A). ).

  Since the second conductor layer pattern 22p laminated on each surface of the first wiring board 10 having a double-sided wiring structure can be connected to each other by the outer conductive wire crossing terminal 35, the electric wire having a multilayer (four-layer) structure It becomes possible to improve the degree of freedom of wiring of the second conductor layer pattern 22p on the composite printed wiring board 1.

  Further, by supplying (applying) a signal (potential) of the electric wire 31 (outer conductor 31s) to the second conductor layer pattern 22p located at a position that covers the conductor 31c away from the conductor 31c, an electric signal from the outside to the conductor 31c is supplied. It can be set as the electric wire component 30 which can exclude an influence.

  The outer conductor crossing end portion 35p has a planar shape facing the second conductor layer pattern 22p in order to easily and accurately connect the second conductor layer pattern 22p. That is, the outer conductor crossing terminal 35 has an outer shape configured as a rectangular parallelepiped, and is configured to be connected to the outer conductor 31s through the electric wire 31 in the center. The outer conductor crossing terminal 35 is not limited to a rectangular parallelepiped as long as it has a shape that can be connected to the second conductor layer pattern 22p by the outer conductor crossing end 35p.

  3C is an explanatory view schematically showing another example as an intermediate product of the electric wire component according to Embodiment 1 of the present invention, in which (A) is a plan view, (B) is a front view, and (C ) Is a side view showing the tip side.

  The outer conductor crossing terminal 35 has the same configuration as in FIG. 3A. The conducting wire extension terminal 32 is configured differently from the case of FIGS. 3A and 3B. Hereinafter, mainly different points will be described.

  The conductor extension terminal 32f has a height Hf in the stacking direction of the wiring boards (the first wiring board 10 and the second wiring board 20) with respect to the conductor connecting portion 32c. The conductive wire extension plate portion 32f extends from the connection portion 32c and protrudes from the resin sealing portion 39 (see FIG. 4A). By projecting the conductive wire extension plate portion 32f from the resin sealing portion 39, it is possible to easily align the first wiring substrate 10 (the first conductor layer pattern 12p). Further, even when the thickness of the first wiring board 10 is thick, it is possible to easily connect.

  Moreover, the connection part 32c for conducting wires has a configuration in which the outer shape is configured as a rectangular parallelepiped or a cylinder, and is connected to the outer conducting wire 31s by passing the electric wire 31 through the center. With this configuration, it is not necessary to bend the conductive wire connection portion 32c, and the process can be simplified. The conducting wire connection portion 32c and the conducting wire extension plate portion 32f are integrally formed as a conducting wire extension terminal 32 by appropriately connecting individually formed members by welding or the like.

  3D is an explanatory view schematically showing another example as an intermediate product of the electric wire component according to Embodiment 1 of the present invention, in which (A) is a plan view, (B) is a front view, and (C ) Is a side view showing the tip side.

  The outer conductor crossing terminal 35 has the same configuration as in FIG. 3A. The conducting wire extension terminal 32 is configured differently from the case of FIG. 3C. Hereinafter, mainly different points will be described.

  The conducting wire extension terminal 32 is configured not to set the height Hf provided in the case of FIG. 3C. That is, in the wiring board stacking direction (stacking direction of the second wiring board 20 with respect to the first wiring board 10), the conductive wire extension plate portion 32f is connected to the resin sealing portion 39 in the thickness direction of the conductive wire extension plate portion 32f. It becomes possible to set it as the embedded form (refer FIG. 4B thru | or FIG. 4D). The conductive wire extension plate portion 32f extends from the resin sealing portion 39 and faces the first conductor layer pattern 12p.

  In addition, the conductive wire extension terminals 32 (conductive wire connection portion 32c, conductive wire extension plate portion 32f) are disposed symmetrically with respect to the electric wire 31 (conductive wire 31c) in the stacking direction of the wiring board. That is, the electric wires 31 (conductive wire extension terminals 32) are configured to be symmetrically connected in the stacking direction of the second wiring board 20, and the first conductor layer patterns 12p formed on both surfaces of the first wiring board 10, respectively. The second conductor layer pattern 22p stacked on each first conductor layer pattern 12p is connected to each other symmetrically. In addition, the symmetry of the electric wire component 30 in the stacking direction of the second wiring board 20 can be the same for each configuration described below.

  It becomes possible to arrange the first wiring board 10 between the conductive wire extension plate portions 32f arranged symmetrically in the wiring board stacking direction (see FIGS. 10 and 11), and the electric wire 31 is made stronger. It can be connected to the electric wire composite printed wiring board 1. Further, in the stacking direction with respect to each conductor layer pattern (first conductor layer pattern 12p and second conductor layer pattern 22p) of the multilayer (four-layer) structure wiring substrate (first wiring substrate 10 and second wiring substrate 20). It becomes possible to set it as the electric wire composite printed wiring board 1 which has the electric wire components 30 connected symmetrically.

  The outer conductor crossing terminal 35 (outer conductor crossing end 35p) is arranged symmetrically with respect to the electric wire 31 (conductor 31c) in the wiring board stacking direction, like the conductor extension terminal 32. That is, the electric wires 31 (outer conducting wire intersection terminals 35) are configured to be symmetrically connected in the stacking direction of the second wiring board 20, and the outer conducting wire intersection ends 35p are formed on both surfaces of the first wiring board 10. It becomes possible to connect symmetrically to each of the stacked second conductor layer patterns 22p.

  FIG. 3E is explanatory drawing which shows typically the other Example as an intermediate product of the electric wire component which concerns on Embodiment 1 of this invention, (A) is a top view, (B) is a front view, (C ) Is a side view showing the tip side.

  The conductive wire extension terminal 32 (conductive wire extension plate portion 32f, conductive wire connection portion 32c) has the same configuration as in FIG. 3D. The outer conductor crossing terminal 35 shown in FIG. 3A is different in that an outer conductor extension terminal 34 having an outer conductor extension plate part 34f and an outer conductor connection part 34c is connected to the outer conductor 31s. Hereinafter, mainly different points will be described.

  The outer conductor 31s is connected to an outer conductor extension terminal 34 that has an outer conductor extension plate 34f that extends from the resin sealing portion 39 (see FIG. 4B) and faces the first conductor layer pattern 12p. The outer conductor extension terminal 34 includes an outer conductor extension plate part 34f and an outer conductor connection part 34c connected to each other. The outer conductive wire connecting portion 34c is configured to have a rectangular parallelepiped shape or a cylindrical outer shape and to be connected to the outer conductive wire 31s through the electric wire 31 in the central portion. The outer conductor connecting portion 34c and the outer conductor extension plate portion 34f are individually formed and appropriately connected by welding or the like and integrated as an outer conductor extension terminal 34. The outer conductor connecting portion 34c and the outer conductor extension plate 34f can be integrally formed by sheet metal processing.

  In the lead wire extension terminal connecting step, the lead wire extension terminal 34 and the lead wire 31c are connected together with the lead wire extension terminal 32 and the lead wire 31c.

  The outer conductive wire extension plate portion 34 f has a connection hole 34 h connected to the first conductor layer pattern 12 p via a conduction hole conductor 41 formed in the interlayer conduction hole 40 of the second insulating base material 21. Further, the outer conductive wire extension plate part 34f is configured to be connected to the second conductor layer pattern 22p by the conduction hole conductor 41 (see FIG. 14).

  Therefore, the electric wire component 30 can be applied to the electric wire composite printed wiring board 1, and the outer conductive wire 31s (electric wire component 31) can be easily and firmly connected to the first conductor layer pattern 12p (first wiring substrate 10). It becomes possible.

  The outer conductive wire extension plate portions 34f extend in opposite directions from the outer conductive wire connection portions 34c, respectively, and are opposed to the first wiring board 10 on both sides of the conductive wire extension plate portions 32f in the same manner as the conductive wire extension plate portions 32f. Symmetrically juxtaposed. With this configuration, each of the first conductor layer patterns 12p located at positions separated from each other in the opposite direction from the electric wire 31 is connected to the electric wire 31 by crossing the outer conductive wire extension terminal 34, and the outer conductive wire extension terminal 34 is used as a relay portion. The electric wire component 30 that improves the degree of freedom of wiring of the first conductor layer pattern 12p disposed around the conductive wire extension terminal 32 can be obtained.

  The outer conductor extension terminal 34 (outer conductor connection portion 34c, outer conductor extension plate portion 34f) is connected to the electric wire 31 (conductor 31c, outer conductor 31s) in the wiring board stacking direction, like the conductor extension terminal 32. They are symmetrically arranged and connected. That is, the electric wires 31 (external conductor extension terminals 34) are configured to be symmetrically connected in the stacking direction of the second wiring board 20, and the outer conductor extension plates 34f are provided on both surfaces of the first wiring board 10. Each of the first conductor layer patterns 12p formed and the second conductor layer pattern 22p stacked on each first conductor layer pattern 12p are connected symmetrically.

  Therefore, in the stacking direction with respect to each conductor layer pattern (first conductor layer pattern 12p and second conductor layer pattern 22p) of the multilayer (four-layer) structure wiring board (first wiring board 10 and second wiring board 20). It becomes possible to set it as the electric wire composite printed wiring board 1 which has the electric wire components 30 connected symmetrically.

  3F is an explanatory view schematically showing another example as an intermediate product of the electric wire component according to Embodiment 1 of the present invention, in which (A) is a plan view, (B) is a front view, (C ) Is a side view showing the tip side.

  The conductive wire extension terminal 32 (conductive wire extension plate portion 32f, conductive wire connection portion 32c) has the same configuration as in FIG. 3D.

  Accordingly, the electric wire component 30 can be connected with a high degree of freedom according to the arrangement state of the first conductor layer pattern 12p (and the second conductor layer pattern 22p). In addition, when the connection by the connection holes 34h at a plurality of locations is performed on the same first conductor layer pattern 12p (and the second conductor layer pattern 22p), the plurality of connections are different for the same wiring pattern. Since it is performed at the position, it is possible to improve the reliability of interconnection and to suppress the influence of the resistance of the first conductor layer pattern 12p and the second conductor layer pattern 22p.

  For example, as shown in the present embodiment, when the outer conductive wire extension plate portion 34f is extended with respect to the extending direction of the electric wire 31, and a plurality of connection holes 34h are arranged in the extending direction of the outer conductive wire extension plate portion 34f, It is possible to arrange the wire component placement opening 10w corresponding to the extending direction of the outer conductive wire extension plate portion 34f and make the first conductor layer pattern 12p a wiring pattern along the wire component placement opening 10w.

  The conductive wire extension terminal 32 (conductive wire extension plate portion 32f, conductive wire connection portion 32c) has the same configuration as in FIG. 3D. Further, the outer conductor crossing terminal 35 has the same configuration as in FIG. 3A. 3D is different from the case of FIG. 3D in that a covering portion extension terminal 33 having a covering portion extension plate portion 33f and a covering portion coupling portion 33c is coupled to the covering portion 31h.

The extended covering end portion 37p for the outer covering portion is configured to be connected to the second conductor layer pattern 22p via the conduction hole conductor 41 formed in the interlayer conduction hole 40 of the second insulating base material 21.

  With this configuration, each of the second conductor layer patterns 22p located away from each other in the opposite direction from the electric wire 31 is connected to the electric wire 31 by being crossed by the outer covering portion extension crossing terminal 37 (see FIG. 15A). It becomes possible to make the electric wire component 30 that improves the degree of freedom of wiring of the second conductor layer pattern 22p disposed around the conductive wire extension terminal 32f by causing the extended cross terminal 37 to act as a relay portion.

  The outer covering extended extension terminal 37 (outer covering extension extended end 37p) is symmetrical with respect to the electric wire 31 (outer covering 31f) in the wiring board stacking direction, like the conductive wire extension terminal 32. Arranged and abutted. That is, the electric wires 31 (extended covering terminals 37 for the outer covering portion) are configured to abut symmetrically in the stacking direction of the second wiring board 20, and the extended covering end portions 37 p for the outer covering portions are connected to the first wiring. It becomes possible to connect symmetrically to the respective second conductor layer patterns 22p laminated on both surfaces of the substrate 10.

  The extended covering terminal 37 for the outer covering portion can be easily positioned by contacting the electric wire 31 (outer covering portion 31f), so that the resin sealing by the resin sealing portion 39 is performed with high accuracy. Is possible.

  In the lead wire extension terminal connecting step, the outer covering extension extension terminal 37 and the outer covering portion 31f are brought into contact with the connection of the lead extension terminal 32 and the lead wire 31c. When the resin sealing portion 39 is formed, the outer covering portion extended intersection terminal 37 (outer covering portion extended intersection end portion 37p) needs to be resin-sealed in contact with the outer covering portion 31f. For example, the length of the outer covering portion extension crossing terminal 37 is increased and fixed from the outside.

  The intermediate product of the electric wire component 30 shown in FIG. 3A to FIG. 3H and FIG. 3J described above can be combined with the configuration of the other embodiment to make another different embodiment.

  Conductive wire extension terminal 32 (conductive wire connection portion 32c, conductive wire extension plate portion 32f), outer conductive wire extension terminal 34 (outer conductive wire connection portion 34c, outer conductive wire extension plate portion 34f), outer conductive wire intersection terminal 35 ( The outer conductor crossing end portion 35p and the outer conductor extension crossing terminal 36 (outer conductor extension crossing end portion 36p) are made of a material that can be connected to the conductor 31c and the outer conductor 31s. In addition, when connecting by crimping, it is preferable to use soldering together. It is preferable to connect so that air does not remain in a connection part.

Is preferred. It is preferable that the connection with the conduction hole conductor 41 and the conductivity are good. For example, if the conduction hole conductor 41 is copper-plated, it is preferable to apply, for example, copper or a copper alloy that is tin-plated. With this configuration, it is possible to easily connect the conducting wire 31c and the outer conducting wire 31s to the first conductor layer pattern 12p and the second conductor layer pattern 22p.

For example, copper or a copper alloy is preferable. The outer covering portion extended intersection terminal 37 (outer covering portion extended intersection end 37p) is preferably configured in the same manner as the covering portion extension terminal 33.

  The conductor extension terminal 32, the covering extension terminal 33, and the outer conductor extension terminal 34 have a plate thickness of, for example, about 0.1 to 0.3 mm, and a width in the extension direction of the electric wire 31, for example, 0.4 to 1. The length in the extending direction of the electric wire 31 from the resin sealing portion 39 can be about 1.0 to 3.0 mm, for example. By setting the size to this level, it is possible to ensure sufficient mechanical strength and stackability.

  Further, the outer conductor crossing terminal 35 can be sized so as to be housed in the resin sealing portion 39, and the outer conductor extension crossing terminal 36 and the outer covering extension crossing terminal 37 are conductor extensions. It is possible to make the thickness about the same as that of the terminal 32, and to have a size that can fit on both surfaces of the resin sealing portion 39 facing the second wiring board 20.

Is a front view, (C) is a side view showing the tip side.

  4A shows a state of the resin sealing portion 39 formed by resin sealing the end portion of the electric wire 31 shown in FIG. 3C. As described with reference to FIG. 3C, the conductive wire extension terminal 32 (conductive wire extension plate portion 32 f) protrudes from the resin sealing portion 39 in the stacking direction of the wiring substrate at a height Hfs, and the first wiring substrate 10 (first conductor). The layer pattern 12p) is opposed to the layer pattern 12p).

  The connection hole 32h formed in the conductive wire extension plate portion 32f is resin-sealed in a form that is exposed from the resin sealing portion 39. With this configuration, the interlayer conduction hole 40 formed in the second insulating base 21 can easily face the first conductor layer pattern 12p through the connection hole 32h.

  The end portion of the electric wire 31 is resin-sealed, and the conductive wire extension terminal 32 is also resin-sealed in an appropriate shape (resin sealing step). The electric wire component 30 provided with the electric wire 31 and the resin sealing part 39 will be comprised by a resin sealing process. The resin sealing in the resin sealing step is appropriately performed by applying, for example, a transfer mold technique, an appropriate mold, an appropriate sealing resin (preferably a resin material similar to that of the wiring substrate), and the like. It is possible.

  The resin sealing portion 39 is preferably juxtaposed with the first wiring board 10 and formed in a rectangular parallelepiped so that the second wiring board 20 is laminated (see FIG. 10). The upper and lower surfaces (surface corresponding to the conductive wire extension plate portion 32f) of the rectangular parallelepiped face the second wiring board 20 (second insulating base material 21), and the tip surface (the surface opposite to the surface from which the electric wire 31 is led out) That is, the extending direction of the electric wires 31) is arranged in parallel to face the first wiring board 10.

  Further, the outer conductive wire intersection terminal 35 (outer conductive wire intersection end portion 35 p) is disposed so as to be exposed on the surface of the resin sealing portion 39 so as to face the second insulating substrate 21.

  The extension terminal 32 for conducting wire and the intersecting terminal 35 for outside conducting wire are both resin-sealed and held by the resin-sealing portion 39, so that a structurally stable terminal portion can be configured.

  4B to 4D are explanatory views schematically showing other examples in which the ends of the electric wires in the electric wire component according to Embodiment 1 of the present invention are resin-sealed. A top view, (B) is a front view, (C) is a side view which shows the front end side. Since the basic configuration is the same as that of the electric wire component shown in FIG.

  FIG. 4B shows a state of the resin sealing portion 39 formed by resin sealing the end portion of the electric wire 31 shown in FIG. 3E. The conductive wire extension terminal 32 (conductive wire extension plate portion 32f, connection hole 32h) is extended from the front end surface of the resin sealing portion 39, and the conductive wire extension plate portion 32f and connection hole 32h are opposed to the first conductor layer pattern 12p. As a form to do. With this configuration, it is possible to prevent peeling in the stacking direction of the conductive wire extension terminals 32 and improve the fixing strength.

  Further, the outer conductor extension terminal 34 (outer conductor extension plate portion 34f, connection hole 34h) is extended from the front end surface of the resin sealing portion 39 in the same manner as the conductor extension terminal 32 (conductor extension plate portion 32f). The outer conductive wire extension plate part 34f and the connection hole 34h are configured to face the first conductor layer pattern 12p. By extending the conductive wire extension plate portion 32f from the front end surface of the resin sealing portion 39, the resin sealing portion 39 can be reliably and firmly fixed.

  In addition, also in the case of the resin sealing part 39 formed by resin-sealing the edge part of the electric wire 31 shown in FIG. 3G, it will be in the same state as FIG. 4B.

  FIG. 4C shows a state of the resin sealing portion 39 formed by resin sealing the end portion of the electric wire 31 shown in FIG. 3F. As described in FIG. 3F, the conductor extension terminal 32 (conductor extension plate portion 32f, connection hole 32h) is the same as FIG. 3D (FIG. 3E). That is, the conductive wire extension terminal 32 (conductive wire extension plate portion 32f, connection hole 32h) is extended from the front end surface of the resin sealing portion 39 and faces the first conductor layer pattern 12p, as in FIG. 4B. .

  Further, the outer conductor extension terminal 34 (outer conductor extension plate 34f, connection hole 34h) is different from the case of FIG. 4B. That is, it protrudes from the resin sealing part 39 not only at the front end surface of the resin sealing part 39 but also in the side surface direction intersecting with the electric wire 31.

  As shown in FIG. 3F, a plurality of outer conductor extension plate portions 34f are formed in a distributed manner along the extension direction of the outer conductor extension plate portion 34f (the direction parallel to the extension direction of the conductor extension plate portion 32f). A connecting hole 34h. Since the plurality of connection holes 34h are resin-sealed in a state of protruding from the side surface (direction intersecting the electric wire 31) of the resin sealing portion 39, the corresponding first conductor layer is provided at a plurality of corresponding positions. It becomes possible to be connected to the pattern 12p (and the second conductor layer pattern 22p).

  In other words, the configuration (first wiring board 10 in FIG. 3F) is also opposed to the first wiring board 10 (first conductor layer pattern 12p) disposed on the side surface of the resin sealing portion 39 (direction intersecting the electric wires 31). The degree of freedom of wiring of the first conductor layer pattern 12p can be improved. Therefore, it is possible to provide the electric wire composite printed wiring board 1 having a high degree of freedom in wiring.

  FIG. 4D shows a state of the resin sealing portion 39 formed by resin sealing the end portion of the electric wire 31 shown in FIG. 3J. The conductive wire extension terminal 32 (conductive wire extension plate portion 32f, connection hole 32h) partially protrudes from both the upper and lower surfaces of the resin sealing portion 39 and extends from the front end surface of the resin sealing portion 39 to be a first conductor. The layer pattern 12p is opposed to the layer pattern 12p. Further, the covering portion extension terminal 33 (covering portion extension plate portion 33f, connection hole 33h) is disposed in the same manner as the conducting wire extension terminal 32 (conducting wire extension plate portion 32f). Accordingly, the difference in planar shape between the conductive wire extension plate portion 32f and the covering portion extension plate portion 33f appears on the surface of the resin sealing portion 39 as it is. Since the lead wire extension terminal 32 and the covering portion extension terminal 33 are partially fixed by the resin sealing portion 39, the mechanical strength can be secured.

  Further, the outer conductor extended cross terminal 36 (outer conductor extended cross end portion 36p) and the outer covering portion extended cross terminal 37 (outer covering portion extended cross end portion 37p) are exposed on the surface of the resin sealing portion 39. The resin sealing portion 39 is disposed so as to be flush with the surface. The outer conductor extended crossing end portion 36p and the outer covering portion extended crossing end portion 37p are flush with the resin sealing portion 39, and therefore can face the second insulating substrate 21 with high precision flatness. It is possible to connect the second conductor layer pattern 22p with high accuracy.

  If the outer covering portion extension crossing terminal 37 is not fixed to the electric wire 31, as described above, the outer covering portion extension crossing terminal 37 is further extended and fixed on the mold side. After forming the resin sealing portion 39, it is possible to configure by cutting off an excess portion protruding from the resin sealing portion 39 to match the outer shape of the resin sealing portion 39.

  Since the connection hole 32h, the connection hole 33h, and the connection hole 34h are exposed to the outside of the resin sealing portion 39, the connection to the first conductor layer pattern 12p by the conduction hole conductor 41 is facilitated and the reliability is improved. be able to. Further, since the outer conductor crossing end 35p, the outer conductor extended crossing end 36p, and the outer covering extension extended crossing 37p are exposed on the surface of the resin sealing portion 39, the second conductor by the conduction hole conductor 41 is provided. The connection to the layer pattern 22p can be facilitated and the reliability can be improved.

  The resin sealing portion 39 has physical properties equivalent to or higher than those of the first insulating base material 11 and the second insulating base material 21 (for example, heat resistance characteristics, electrical characteristics, hardness) in order to prevent deformation due to thermal expansion. And the like. For example, an epoxy resin or the like can be applied.

Step S4:

That is, in order to improve the connectivity with the first wiring board 10 (first conductor layer pattern 12p) and the second wiring board 20 (second conductor layer pattern 22p), the first conductor layer pattern 12p and the second conductor layer. The surface to be connected to the pattern 22p is roughened.

  For example, the conductor extension terminal 32 (conductor extension plate part 32f), the covering part extension terminal 33 (covering part extension plate part 33f), and the outer conductor extension terminal 34 (outside conductor use) shown in FIGS. 4A to 4D.

That is, the case where both ends of the electric wire 31 are resin-sealed by the resin sealing portion 39 is shown. In addition, although the electric wire component 30 is made into the symmetrical form at both ends, it is not restricted to this, The other edge part may differ with respect to one edge part.

The second conductor layer patterns 22p are symmetrically connected to each other.

  Therefore, as described above, the electric wire composite printed wiring board 1 having the electric wire components 30 symmetrically connected on both sides to each conductor layer pattern of the wiring board having a multilayer (four layers) structure can be obtained.

For example, the interlayer conduction hole 40w and the interlayer conduction hole 40 can be formed by continuous laser processing.

  The second insulating base material 21 is filled between the connection hole 32h and the first conductor layer pattern 12p, but interlayer conduction is achieved by etching the second insulating base material 21 using the connection hole 32h as a mask. The hole 40 can be easily formed.

An example will be described. A second conductor layer pattern 22pi is formed for the connection hole 32h, and a second conductor layer pattern 22ph is formed for the connection hole 33h.

  Note that the second conductor layer patterns 22pa, 22pb, 22pc, 22pd, 22pe, 22pf, and 22pg are appropriately connected to the electric wire component 30 and the first wiring board 10 through the plurality of conductive hole conductors 41 included therein. If there is no need to distinguish the second conductor layer patterns 22pa, 22pb, 22pc, 22pd, 22pe, 22pf, 22pg, 22ph, and 22pi, they are simply referred to as the second conductor layer pattern 22p. 8 is applied to the arrangement state of the first conductor layer pattern 12p, and the arrangement state of each terminal of the electric wire component 30 is described with reference to FIG.

In addition, the second conductor layer patterns 22pb and 22pc connected to the outer covering portion extended intersection end portion 37p through the second conductor layer pattern 22pa are electrically connected to the interlayer conduction hole 40 of the second insulating base material 21. It is connected to the first conductor layer pattern 12p via the hole conductor 41.

  Accordingly, the second conductor layer pattern 22pb and the second conductor layer pattern 22pc cross the first conductor layer pattern 12p at a position away from the electric wire 31 in the opposite direction to the electric wire 31 by the outer covering portion extended intersection terminal 37. Can be connected. That is, the degree of freedom of wiring of the first conductor layer pattern 12p can be improved, and the first conductor layer pattern 12p surrounding the conductive wire extension terminal 32 can be obtained.

Since each of the second conductor layer patterns 22p located in the direction away from each other can be connected to the electric wire 31 by the covering extension terminal 33, the second conductor layer pattern 22p is arranged around the conducting wire extension terminal 32. It is possible to improve the degree of freedom of wiring of the two conductor layer pattern 22p.

  In the region corresponding to the second conductor layer pattern 22pi, the conductor extension plate portion 32f passes through the connection hole 32h of the conductor extension plate portion 32f and reaches the first conductor layer pattern 12p. It is connected to the first conductor layer pattern 12p through a conduction hole conductor 41 formed in the interlayer conduction hole 40.
