In particular, a pin that can be easily set on a pin setting jig, a pin setting method that can easily set a pin on a pin setting jig, and a pin setting board that can be easily set and can be manufactured at low cost. It relates to a manufacturing method.

[0002]

2. Description of the Related Art Heretofore, there has been known a pin standing board in which a large number of pins as input / output terminals are erected on a board body.
In manufacturing such a pin standing board, the pins are usually set up on the board body as follows. That is, first, a pin setting jig for setting the pins in a protruding state is prepared. As shown in FIG. 14A, the pin setting jig 101
Has a substantially plate shape having an upper surface 101A and a lower surface 101B, and a large number of through holes 104 penetrating between upper and lower surfaces are formed. The through hole 104 includes a chamfered portion 103 which is chamfered so that a pin can be easily inserted, and a distal end portion insertion hole 102 which is located at the back thereof.

Next, the upper surface 10 of this pin setting jig 101
A large number of pins 111 are placed on 1A. This pin 111
Is composed of an engaging portion 112 and a distal end portion 113 and a proximal end portion 114 extending in opposite directions from the engaging portion. Tip 113
And the diameter of the proximal end 114 is substantially the same,
Has been smaller than. The distal end 113 is longer in the axial direction than the proximal end 114.

[0004] Next, by vibrating or swinging the pin setting jig 101, the pin 111 is moved on the pin setting jig 101.
To move. At the same time, the air in the through hole 104 is sucked from the lower surface 101B side of the pin setting jig 101, and FIG.
As shown in FIG. 4B, the pin 11 is inserted into the distal end insertion hole 102.
1 is inserted. At this time, the pin 111
In order for the base end 114 of the pin 111 to be inserted into the substrate main body, it is necessary to insert the front end 113 of the pin 111 into the front end insertion hole 102 of the pin stand jig 101.

Next, a substrate body 121 having a substantially plate shape having an upper surface 121A and a lower surface 121B and having a large number of pin connection holes 122 is prepared at a position corresponding to the tip insertion hole 102 of the pin setting jig 101. . And FIG.
As shown in (c), the pin setting jig 101 on which the pins 111 are set is aligned with the substrate main body 121, and the substrate main body 1 is positioned.
The base end 114 of the pin 111 protruding from the pin stand jig 101 is inserted into the pin connection hole 122 of the pin 21. afterwards,
When the pins 111 and the board body 121 are soldered, the pins 111 are erected on the board body 121.

[0006]

However, when the pin 111 is inserted into the tip insertion hole 102 of the pin stand jig 101, the tip 113 of the pin 111 should be inserted. As shown in the figure, the base end 114 side of the pin 111 is actually inserted at a considerable rate. In particular, like the pin 111, the tip 113
When the difference between the shape and the length of the base end 114 is small,
At a ratio close to half, the base end 114 side of the pin 111 is inserted into the distal end insertion hole 102 of the pin setting jig 111. When the pin 111 is inserted in the opposite direction as described above, it is necessary to pull out the pin 111 by hand or the like, change the direction, and then reinsert the pin 111, which requires a lot of time and labor. For this reason, the cost of the pin standing substrate has been increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is a pin which can be easily set in a fixed direction with a pin setting jig, and a pin which is set in a pin setting jig with a fixed direction of the pin. Easy to set up and set up pins,
It is an object of the present invention to provide a method for manufacturing a pin standing substrate which can be manufactured at low cost.

[0008]

Means for Solving the Problems, operation and effect] The solutions are erected form fitting Yu the pin stand jig having a large number of open tip insertion hole of the main surface on the main surface side of the perforated Sico, Pins which stand upright on the board body as input / output terminals, the engaging portion and the distal end portion and the base end portion which extend in the opposite directions from the engaging portion, and which stand upright on the board body. The above group
The base end portion inserted into the pin connection hole of the plate body, the substrate
The above-mentioned engaging portion which engages with the pin connection hole of the main body;
The distal end portion protruding from the plate body, the maximum dimension in the direction orthogonal to the axis of the engagement portion is larger than the maximum dimension in the direction orthogonal to the axis of the distal end portion and the base end portion, The maximum dimension of the proximal end is greater than the maximum dimension of the distal end, the distal end can be inserted into a distal end insertion hole of the pin setting jig, and the proximal end can The pin is not insertable into the insertion hole at the tip of the tool.

[0009] When this pin is set up on a pin setting jig provided with a large number of distal end insertion holes, when a distal end of the pin that can be inserted into the pin is inserted into the distal end insertion hole, the base end of the pin is inserted. The pin is loosely set on the pin setting jig with the part side protruding. On the other hand, the proximal end of the pin cannot be inserted into the distal end insertion hole, so that the pin does not stand on the pin standing jig with the distal end of the pin protruding. For this reason, when a large number of pins are placed on the pin setting jig and the pins are moved on the pin setting jig, the pins are inserted from the distal end side but not from the base end side. Therefore, it can be easily inserted into all the tip insertion holes of the pin stand jig.
The tip can be correctly inserted to allow the pin to stand.

Here, the shape of the pin is such that the maximum dimension of the engaging portion is larger than the maximum size of the distal end portion and the proximal end portion, and the maximum size of the proximal end portion is larger than the maximum size of the distal end portion. The shape of the distal end portion, the engaging portion, and the proximal end portion can be appropriately selected. For example, the distal end, the engaging portion, and the base end may be substantially cylindrical, and their cross-sections may be substantially elliptical, substantially elliptical, quadrangular, hexagonal, or other polygonal or other shapes. . Further, the shape of the distal end portion, the engagement portion, and the proximal end portion may be different from each other.

Further, in the above pin, the distal end has a diameter smaller than the diameter of the distal end insertion hole, and the base end has the maximum dimension larger than the diameter of the distal end insertion hole. It is good to make it the pin which is also large.

The tip of the pin is often substantially circular in cross section. In accordance with this, the tip insertion hole of the pin setting jig often has a substantially circular cross section. When the distal end portion and the distal end insertion hole have such shapes, the distal end portion of the pin is easily inserted into the distal end insertion hole. Further, the processing of the pin and the distal end insertion hole is also facilitated. According to the present invention, the diameter of the distal end of the pin is smaller than the diameter of the distal end insertion hole of the pin stand jig, and the maximum dimension of the base end of the pin is larger than the diameter of the distal end insertion hole. Therefore, when a large number of pins are placed on the pin setting jig and the pins are moved on the pin setting jig, the pins are easily inserted into the distal end insertion holes from the distal end side. However, it is not inserted from the proximal end side of the pin. Therefore, it can be easily inserted into all the tip insertion holes of the pin stand jig.
The tip can be correctly inserted to allow the pin to stand.

[0013] In the above-mentioned pin, it is preferable that the vicinity of the proximal end of the proximal end has a dimension larger than the diameter of the distal end insertion hole.

According to the present invention, the dimension of the proximal end of the pin near the proximal end is larger than the diameter of the distal end insertion hole of the pin setting jig. For this reason, it is possible to prevent a part of the proximal end of the pin (the proximal end) from being inserted into the distal end insertion hole of the pin stand jig. Therefore, when a large number of pins are placed on the pin setting jig and the pins are moved on the pin setting jig, the tips are more securely inserted into all the tip insertion holes of the pin setting jig. Pins can be made to stand.

[0015] Other solutions, the pin stand jig comprises a number of tip insertion hole having an open main surface on the main surface side of the perforated Sico, many erected on the substrate main body as input and output terminals a pin stand method to make a pin loosely shape, at the tip and a proximal end extending in opposite directions from the engaging portion between the engaging portion
And, when standing on the board body, the board
The base end inserted into the pin connection hole of the body, the substrate body
The engagement portion engaging with the pin connection hole of
The distal end protruding from the body, the maximum dimension in the direction orthogonal to the axis of the engagement portion is greater than the maximum dimension in the direction orthogonal to the axis of the distal end and the proximal end, the proximal end The maximum dimension of the part is larger than the maximum dimension of the distal end, the distal end is insertable into the distal end insertion hole, and the base end is the pin that cannot be inserted into the distal end insertion hole, A pin disposing step of disposing a large number of pins on the main surface of the pin stand jig, and moving the pins placed on the main surface to loosely fit the tips of the pins into the many tip insertion holes. And a pin setting step of setting the pin in a state where the base end portion protrudes.

According to the present invention, in the pin arranging step,
A large number of pins having different sizes of the distal end portion and the proximal end portion and capable of inserting only the distal end portion are provided on the main surface of the pin setting jig. Then, in the pin setting step, the pins are set on a pin setting jig. In the pin setting step, when the tip of the pin is inserted into the tip insertion hole by moving the pin on the pin setting jig, the pin is set in a state where the base end side of the pin protrudes. The jig is loosely set on the jig.
On the other hand, the proximal end of the pin cannot be inserted into the distal end insertion hole, so that the pin does not stand on the pin standing jig with the distal end of the pin protruding. Therefore, the pins can be easily and correctly set up in all the insertion holes at the tip end of the pin setting jig. Therefore, unlike the related art, it is not necessary to once pull out the pin whose base end side is erroneously inserted into the distal end insertion hole from the distal end insertion hole and reinsert it again in the correct direction, that is, from the front end side.

Here, as a method of moving the pin,
For example, in addition to swinging or vibrating the pin setting jig, a method of blowing air to the pin or directly moving the pin with a brush can be used. The material of the pin setting jig may be appropriately selected in consideration of the subsequent processing method of the pin (such as soldering, brazing, or press-fitting), the coefficient of thermal expansion, and the strength. Highly easy to process, carbon, machinable ceramics such as boron nitride, ceramics such as alumina and silicon nitride,
Examples of the material include metals such as steel and stainless steel.

It is sufficient that the distal end insertion hole of the pin stand jig is opened at least on the main surface side, and may be a bottomed hole or a through hole. Further, for example, in order to facilitate insertion of the pin, a chamfered portion or the like which is tapered toward the main surface side may be provided on the main surface side of the distal end insertion hole. Further, for example, a large-diameter portion having a larger diameter than the distal-end insertion hole can be provided on the back surface (the surface opposite to the main surface) of the distal-end insertion hole.

Further, in the above pin setting method, the pin setting step may include, among the plurality of pins on the main surface of the pin setting jig, removing the pins that have not been inserted into the distal end insertion holes. It is preferable to use a pin setting method characterized by including a pin removing step for removing.

When the pins on the pin holder are moved to insert the pins into the distal end insertion holes, some of the pins are caught in the distal end insertion holes or a plurality of pins are combined to form the distal end insertion holes. In a state where vibrations and swings cannot solve these problems. In such a state, the pin is not correctly inserted into the distal end insertion hole at that portion. On the other hand, according to the present invention, in the pin removing step included in the pin setting step, the pin caught in the distal end insertion hole can be reliably removed and the clogged pin can be reliably removed. Can be correctly inserted from the tip end side. Therefore, the pin can be more reliably inserted from the front end into all the front end insertion holes of the pin stand jig. Here, as a method of paying the pins, there are a method of blowing off the pins by blowing air, and a method of directly removing the pins with a brush.

As another solution, a large number of pins as input / output terminals are erected on a substrate body having a substrate main surface and having a large number of pin connection holes opened on the substrate main surface side. A method of manufacturing a pin standing substrate, having a main surface,
Among the pin stand jigs provided with a large number of distal end insertion holes opened on the main surface side, an engaging portion and a distal end portion and a proximal end portion extending in opposite directions from the engaging portion on the main surface. The maximum dimension in the direction orthogonal to the axis of the engaging portion is larger than the maximum dimension in the direction orthogonal to the axis of the distal end and the proximal end, and the maximum dimension of the proximal end is the distal end. A pin arrangement step of arranging a large number of the pins, the number of which is larger than the maximum dimension of the pin, the tip portion is insertable into the tip portion insertion hole, and the base end portion is not insertable into the tip portion insertion hole, A pin stand for moving the pins placed on the main surface, loosely inserting the tips of the pins into the large number of tip insertion holes, and setting the pins in a state in which the base end protrudes. Step, align the pin stand jig with the pins up, and the substrate body, A plurality of pin connection holes of the substrate body,
Preferably, a method of manufacturing a pin-standing substrate, comprising: inserting a base end of the pin protruding from the pin-standing jig and engaging an engaging portion.

According to the present invention, in the pin arranging step,
A large number of pins are arranged on the main surface of the pin setting jig. Then, in the pin setting step, the pins are set on a pin setting jig. In the pin setting step, when the tip of the pin is inserted into the tip insertion hole by moving the pin on the pin setting jig, the pin is inserted with the base end side protruding. The jig is loosely set on the jig. On the other hand, the proximal end of the pin cannot be inserted into the distal end insertion hole, so that the pin does not stand on the pin standing jig with the distal end of the pin protruding. Therefore, the pins can be easily and correctly set up in all the insertion holes at the tip end of the pin setting jig.

Then, in the pin insertion step, when inserting the pins into the pin connection holes of the substrate main body, the pins set on the pin setting jig are all protruded from the base end side, so that Only the ends can be inserted into the pin connection holes. As described above, in the present invention, the pins are easily erected on the substrate body with the direction thereof fixed, so that the pins inserted into the pin stand jig in the opposite direction are manually removed as in the related art. There is no need to change the orientation and reinsert. Therefore, it is possible to greatly reduce the time and labor, and it is possible to manufacture the pin standing board at a lower cost as compared with the conventional method of manufacturing the pin standing board.

The substrate body may be made of a resin such as an epoxy resin or an insulating material made of a composite material of these resins and glass fiber, or may be made of alumina, aluminum nitride, mullite or glass. A ceramic material using an insulating material made of a ceramic such as a ceramic may be used. In addition, a wiring layer formed on the surface or inside thereof, an integrated circuit chip, a wiring board on which the integrated circuit chip is mounted, connection pads for connecting chip components, other electronic components, etc., a solder resist layer, etc. Is also included.

The shape of the pin connection hole of the substrate body may be appropriately changed in consideration of the shape of the base end of the pin inserted into the pin connection hole, the securing of the bonding strength between the pin and the substrate body, and the like. it can. For example, there are a bottomed hole that opens only on the main surface side of the substrate main body, a through hole that penetrates the substrate main body, and the like. In addition, as a method of fixing the pin to the substrate main body, the shape of the base end of the pin and the pin connection hole is adjusted, and the base end of the pin is pressed into the pin connection hole and fixed, or the pin is fixed to the substrate main body. For example, by soldering. Also, a through hole is provided in the substrate body as a pin connection hole,
A method of inserting a pin having a base end longer than the thickness of the substrate main body, crushing a portion protruding from the substrate main body with a press, and fixing the same is also included.

Further, in the above-mentioned method of manufacturing a pin standing board, the pin setting step may include, among the plurality of pins on the main surface of the pin setting jig, the pin not yet inserted into the tip portion insertion hole. It is preferable to provide a method for manufacturing a pin standing substrate, which includes a pin removing step of removing the pins.

[0027] If such a pin removing step is included in the pin setting step, the pin stuck or clogged in the tip end insertion hole can be reliably removed.
The pin can be correctly inserted into the distal end insertion hole from the distal end side. For this reason, the pin can be more reliably inserted from the front end side into all the front end insertion holes of the pin stand jig. Therefore, in the pin insertion step, only the base end of the pin protruding from the pin stand jig can be reliably inserted into all the pin connection holes of the substrate body.

It has a substantially cylindrical shape of 08 mm. The base end 4 has a cross section of a short diameter of 0.4 mm and a long diameter of 0.5 mm.
With a height (length in the axial direction) of 1.05
mm.

Therefore, the pin 1 is connected to the shaft A-
Maximum dimension in the direction orthogonal to A '(diameter of engaging portion 2 = 0.7
mm) is the maximum dimension of the distal end 3 in the direction orthogonal to the axis AA ′ (diameter of the distal end 3 = 0.45 mm), and the maximum dimension of the proximal end 4 in the direction orthogonal to the axis AA ′. (0.5 mm). Further, the maximum dimension (0.5 mm) of the base end 4 is larger than the diameter (0.45 mm) of the distal end 3.

Next, FIG. 2 shows a state where the pin 1 is set up on the pin setting jig 11. The pin stand jig 11 used in the present embodiment is made of carbon, has a main surface 11A (upper in the figure) and a back surface 11B (lower in the figure), and has a size of 53.3 ×.

However, when viewed from the main surface 11A side, they are formed side by side in a substantially lattice shape (not shown). The through-hole 14 is formed by a chamfered portion 13 that is tapered toward the main surface 11A and a tip insertion hole 12 that is located deeper (downward in the drawing) than the chamfered portion 13 and that opens toward the main surface 11A. Become.

The tip insertion hole 12 has a substantially cylindrical shape with a maximum dimension in the direction perpendicular to the axis (diameter of the tip insertion hole 12) of 0.48 mm in diameter.

The engaging portion 2 of the pin 1 engages with the chamfered portion 13. In this state, even when an external force is applied in a direction perpendicular to the axis of the distal end insertion hole 12 (the left-right direction in the figure), the pin 1 maintains the state of standing in the axial direction of the distal end insertion hole 12.

On the other hand, as shown in FIG. 2B, the base 1 side of the pin 1 is
, That is, when inserting the pin 1 in the reverse direction, the base end 4 is not
The base end portion 4 is not inserted into the distal end portion insertion hole 12 only by inserting a part of the base end portion 4 into the end portion 3. As shown in FIG. 2B, the state in which the base end portion 4 of the pin 1 is slightly inserted into the chamfered portion 13 is very unstable, so that the pin 1 can be easily applied only by a slight external force. To fall.

Next, FIG. 3 (a) shows a front view and FIG. 3 (b) shows a partially enlarged sectional view of the pin standing board 20 manufactured in this embodiment. The pin standing substrate 20 has a substantially square shape of 49.3 × 49.3 mm in plan view and is shown in FIG.

There are many standing.

As shown in FIG. 3B, the substrate body 21 has a resin insulating layer 22 made of epoxy resin, and the resin insulating layer 22 has a main surface 22A (a lower part in the figure). A large number of pin connection holes 23 penetrating between the back surface 22B (upper side in the figure) are formed. The inner wall surface 23A of the pin connection hole 23, the pin connection hole periphery 22AR of the main surface 22A of the resin insulating layer 22, and the pin connection hole periphery 22 of the back surface 22B.
The conductor layer 25 made of copper is formed on the BR. Note that, due to the conductor layer 25 formed on the inner wall surface 23A of the pin connection hole 23, the opening of the pin connection hole 23 has a diameter of 0.3 mm.
55 mm.

On the back surface 22B of the resin insulating layer 22,
In order to mount an integrated circuit chip, a wiring board on which the integrated circuit chip is mounted, chip components, and other electronic components (not shown) on the substrate body 21, a large number of connection pads 27 are formed. A solder bump 29 made of eutectic solder is formed. The connection pads 27 are electrically connected to the conductor layer 25 via the wiring layers 26, respectively. Further, a solder resist layer 28 made of epoxy resin is provided on the periphery of the connection pad 27 and the conductor layer 25.
Of the resin insulating layer 22 and the wiring layer 26 so as to slightly overlap the periphery of the portion formed on the pin connection hole periphery 22BR of the back surface 22B.

The pin 1 has the base end 4 inserted into the pin connection hole 23 of the substrate body 21 and the engaging portion 2 engaged with the pin connection hole 23. And the tip 3 of the pin 1
It protrudes downward from the main surface 21A of the substrate body 21 in the figure. The base 1 and the engaging portion 2 of the pin 1 are fixed to the conductor layer 25 of the board main body 21 with a solder material 30, so that the pin 1 stands upright on the board main body 21.

Next, a pin 1 and a pin setting jig 11
A method of setting the pins upright and a method of manufacturing the pin upright board 20 will be described with reference to FIGS. FIG. 4 shows a method for manufacturing the pin 1. First, FIG.
As shown in (1), a Kovar wire MT having a substantially circular cross section is prepared. Next, as shown in FIG. 4B, by a known press working, a substantially cylindrical base end portion 4P having substantially the same diameter as the Kovar wire MT, and a substantially disk-shaped base end 4P having a larger diameter than the Kovar wire MT. The engaging portion 2 is formed.

Next, as shown in FIG. 4 (c), the substantially cylindrical base end portion 4P is sandwiched between press dies P1 and P2 whose press surfaces P1A and P2A are substantially flat, respectively (FIG. 4 (c)). Press in between). When pressed, the base end 4 has a substantially elliptical cross section. Next, as shown in FIG. 4D, the Kovar wire MT is cut at a predetermined position,
The tip 3 is formed. After that, barrel polishing,
In order to prevent oxidation, the surface is plated with Ni-Au (not shown). Thus, the pin 1 is manufactured. Therefore, the proximal end 3
Since it is sufficient only to add a pressing step for forming the pin 1, the pin 1 can be easily manufactured.

Next, the pin setting method and the pin setting board 20
A method of manufacturing the device will be described. As shown in FIG. 5A, the pin setting jig 11 is manufactured in advance. The pin setting jig 11 is manufactured by drilling a large number of distal end insertion holes 12 in a substantially square plate made of carbon by a known method, and further forming a chamfered portion 13 on the main surface 11A side. You. First, in the pin arrangement step, FIG.
As shown in (a), a large number of pins 1 are placed on the main surface 11A of the pin setting jig 11.

Thereafter, in a pin setting step, FIG.
As shown in (b), the pin stand jig 11 is vibrated or rocked to move the pin 1 on its main surface 11A. At the same time, the back surface 11 of the pin setting jig 11
From the side B, the air in each through hole 14 is sucked,
The pin 1 is inserted into the (tip insertion hole 12). By doing so, the pins 1 are inserted into some of the many distal end insertion holes 12.

At this time, the distal end 3 of the pin 1 is easily inserted into the distal end insertion hole 12, and the pin 1 is loosely fitted in the state that the base end 4 is projected. (See FIG. 2A). On the other hand, the pin 1 is not inserted from the base end 4 side. This is because the dimensions of the proximal end 4 of the pin 1 and the vicinity of the proximal end 4A are larger than the diameter of the distal end insertion hole 12 of the pin stand jig 11. In addition, the base end 4
May be inserted into the chamfered portion 13 of the through hole 14. However, as described above, since this state is very unstable, the pin 1 easily falls down due to the vibration or swing of the pin setting jig 11 (see FIG. 2B). In addition,
In the present embodiment, the distal end 3 of the pin 1 has a substantially cylindrical shape, and the distal end insertion hole 12 of the pin stand jig 11 has a substantially cylindrical shape. 1
Inserted into 2.

Next, in the pin removing step of the pin setting step, as shown in FIG. 6A, using the brush BR, the pin 1 on the pin setting jig 11 which is not inserted into the through hole 14 is used. Can be removed. At this time, at the same time, the pin 1 stuck or clogged in the through hole 14 is removed together. On the other hand, the pin 1 having the distal end portion 3 inserted into the distal end insertion hole 12 is not pulled out while standing in the axial direction of the distal end insertion hole 12 even when the brush BR hits. Therefore, in this step, only the pin 1 into which the tip 3 has been correctly inserted remains in the pin setting jig 11.

Next, a large number of pins 11 are placed on the main surface 11A of the pin setting jig 1 again, and the pin setting jig 11 is vibrated.
The pin 1 is moved while being swung, sucked, and inserted into the distal end insertion hole 12 (see FIG. 5). Thereafter, the pins 1 and the like that have not been inserted into the distal end insertion holes 12 can be removed again with the brush BR (see FIG. 6A). This operation is repeated a plurality of times, and the pins 1 are inserted into all of the tip end insertion holes 12 of the pin setting jig 11 as shown in FIG. When the pin 1 is set on the pin setting jig 11 by such a pin setting method, the pin 1 is correctly inserted into the front end insertion hole 12 only from the front end 3 side. There is no need to re-insert the inserted pin 1, and the work efficiency of temporarily setting the pin 1 can be greatly improved.

Next, in the pin insertion step, FIG.
As shown in FIG. 7B, the pin setting jig 11 on which the pins 1 are set and the substrate body 21 are aligned, and as shown in FIG.
The base ends 4 of the pins 1 protruding from the pin stand 11 are inserted into the pin connection holes 23 opened on the board main surface 21A side of the board body 21. Further, the engaging portions 2 of the pins 11 are respectively engaged with the pin connecting holes 23 of the substrate body 21.
A solder paste 30P for soldering the pins 1 to the substrate main body 21 is provided on the pin connection hole 23 and its peripheral edge (upper side in the drawing) of the substrate back surface 21B of the substrate main body 21.
Print. In this step, since the pins 1 erected on the pin erection jig 11 project from the base end 4 side, the base end 4 side of the pin 1 is inserted into the pin connection hole 23 of the substrate body 21. Is done.

Thereafter, the substrate main body 2 stacked via the pins 1
1 and the pin setting jig 11 are put into a reflow furnace and reflowed, and the pins 11 and the substrate main body 21 are fixed to each other with a solder material 30. At the time of reflow, the melted solder spreads along the conductor layer 25 of the substrate main body 21 and the base end 4 of the pin 1 and the like, and the conductor layer 25 and the base end 4 of the pin 1 and the engagement part 2
(See FIG. 3B). Thus, each pin 1 is erected on the substrate main body 21, and the pin erected substrate 20 is completed.

As described above, when the pin 1 of the present embodiment is inserted into the pin insertion hole 12 from the tip 3 side when the pin 1 is set on the pin setting jig 11, the pin 1 loosens in the pin setting jig 11. The pin 1 is set up, but is not inserted from the base end 4 side of the pin 1. Therefore, the tip 1 can be easily and correctly inserted into the pin setting jig 11 and the pin 1 can be set up.
In the pin setting method of the present embodiment, the pin setting jig 1 is used.
1 is moved so that the pin 1 is inserted into the distal end insertion hole 12.
, The pin 1 is inserted from the distal end 3 side, but not from the proximal end 4 side. Therefore, unlike the related art, there is no need to once remove the pin 11 erroneously inserted from the base end portion 4 side through the distal end insertion hole 12 and reinsert it from the distal end portion 3 side.

In the method of manufacturing the pin standing substrate 20 according to the present embodiment, in the pin setting step, the pin setting jig 11 is easily and correctly inserted from all the tip end insertion holes 12 from the tip end 3 side. , Pin 1 can be set up. Furthermore, only the base end 4 side of the pin 1 can be inserted into the pin connection hole 12 of the board main body 21 in the pin insertion step. For this reason, the pin 1 inserted in the opposite direction is pulled out by hand or the like,
There is no need to change the direction and reinsert, so that time and labor can be greatly reduced. Therefore, the pin standing substrate 20 can be manufactured at a lower cost than in the past.

In this embodiment, in the pin setting step, the through holes 14 are formed from the back surface 11B side of the pin setting jig 11.
The pin 1 is easily inserted into the distal end portion insertion hole 12 by sucking the air inside. However, only by vibrating or swinging the pin setting jig 1 without performing such suctioning,
The pin 1 can be set on the pin setting jig 11. In addition, instead of or together with the vibration and swinging of the pin setting jig 11, air can be blown to the pin 1,
The pin 1 can also be set on the pin setting jig 11 by directly paying with a brush.

In the pin setting step of the present embodiment, in order to set the pins 1 more efficiently on the pin setting jig 11, the pins 1 and the like that have not been inserted into the tip end insertion holes 12 in the pin removing step. I'm paying off. However, even without such a step, the pin 1 can be set up on the pin setting jig 11 only by moving the pin 1 on the pin setting jig 11 by vibration or swing.

(Modification 1) Next, a modification 1 of the first embodiment will be described with reference to FIGS.
This will be described with reference to FIG. In this modification, the shape of the pin, particularly the shape of the base end of the pin, is different from the pin 1 of the first embodiment. Therefore, the description of the same parts as those in the first embodiment will be omitted or simplified.

FIG. 8 shows a pin 41 according to this modification.
8A shows a view from the base end portion 44 side, FIG. 8B shows a front view, and FIG. 8C shows a view from the distal end portion 43 side. The pin 41 includes an engaging portion 42, and a distal end portion 43 and a proximal end portion 44 extending from the engaging portion 42 in a reverse manner. The engaging portion 42 and the distal end portion 43 have the same shape as the pin 1 of the first embodiment. On the other hand, the base end 44
Is located on the distal end side, that is, on the side of the engaging portion 42 (the lower part in FIG. 8B), and has a substantially cylindrical shape having substantially the same diameter (0.45 mm in diameter) as the distal end portion 43; 8 (b), and comprises a portion which is tapered toward the base end. Therefore, the vicinity of the proximal end 44A of the proximal end portion 44 has the maximum dimension (0.5 mm) in the direction orthogonal to the axis AA ′. In addition, a substantially mortar-shaped punch hole 45 that is open to the base end side is formed in the tapered portion.

Therefore, this pin 41 is also used in the first embodiment.
Similarly, the maximum dimension of the engaging portion 42 (the diameter of the engaging portion 42 =
0.7 mm) is the maximum dimension of the distal end 43 (diameter of the distal end 43 = 0.45 mm) and the maximum dimension of the proximal end 44 (0.
5 mm). The maximum dimension (0.5 mm) of the base end portion 44 is the diameter (0.45
mm). Note that this pin 41
Similarly, the pin 1 is made of Kovar, similarly to the pin 1 of the first embodiment, and has a Ni-Au plating layer (not shown) on its surface.
Are formed.

Next, FIG. 9 shows a state in which the pin 41 of this modified embodiment is set up on the pin setting jig 11. The pin stand jig 11 is the same as in the first embodiment.
That is, as in the case of the first embodiment, the diameter (0.45 mm in diameter) of the distal end portion 43 of the pin 41 is
Is smaller than the diameter of the distal end insertion hole 12 (0.48 mm in diameter), the distal end 43 can be inserted into the distal end insertion hole 12. On the other hand, the maximum dimension (diameter 0.5 mm) of the base end 44 of the pin 41 is the diameter of the tip end insertion hole 12 (diameter 0.48).
mm) and the vicinity of the proximal end 44A has the maximum dimension, so that the proximal end 44 cannot be inserted into the distal end insertion hole 12.

Therefore, as shown in FIG.
1 is provided with the through hole 14 of the pin stand jig 11
Is inserted into the distal end portion 43 as in the first embodiment.
Is loosely inserted into the distal end insertion hole 12, and the engaging portion 42 of the pin 41 is engaged with the chamfered portion 13. In this state, even when an external force is applied in a direction perpendicular to the axis of the distal end insertion hole 12 (left-right direction in the figure), the pin 41 maintains the state of being set up in the axial direction of the distal end insertion hole 12.

On the other hand, as shown in FIG. 9B, when the base end 44 side of the pin 41 is to be inserted into the through hole 14 of the pin stand jig 11, as in the first embodiment. ,
The base end 44 is only partially inserted into the chamfered portion 13. In this manner, the proximal end portion 44 is inserted into the distal end insertion hole 12.
Therefore, as shown in FIG. 9 (b), the pin in the state where the distal end insertion hole 12 stands upright in the axial direction is very unstable. Therefore, the pin 41 can easily fall down even when a slight external force is applied.

Next, a method of manufacturing the pin 41 will be described with reference to FIG.
This will be described with reference to FIG. First, as shown in FIG. 10A, a Kovar wire rod MT having a substantially circular cross section is prepared in the same manner as the pin 1 of the first embodiment, and as shown in FIG. A substantially cylindrical base end portion 44P having a diameter substantially equal to that of the Kovar wire MT, and a substantially disk-shaped engaging portion 42 having a diameter larger than that of the Kovar wire MT are formed.

Next, as shown in FIG. 10 (c), the punch P is placed substantially at the center of the bottom surface on the base end side of the substantially cylindrical base end portion 44P.
T is pressed in the direction indicated by the arrow in the figure. The punch PT has a substantially conical tip portion and a central angle of about 50 degrees. When pressed with the punch PT, a substantially mortar-shaped punch hole 45 is formed in the base end 44 of the pin 41, and the base end 44 of the pin 41 is oriented in the base end direction (left side in FIG. 10C). ). For this reason, the dimension (maximum dimension) near the proximal end 44 </ b> A of the proximal end 44 is larger than the diameter of the distal end 43.

Next, as shown in FIG. 10D, the Kovar wire MT is cut at a predetermined position in the same manner as the pin of the first embodiment to form the tip 43. After that, processing such as barrel polishing and Ni-Au plating formation is performed,
1 is manufactured. Accordingly, the pin 41 of the present modification is also easy to manufacture because it is sufficient to simply add a pressing step of forming the base end portion 43 with the punch PT to the conventional series of pin manufacturing steps.

The pin setting method using the pins 41 according to the present modification is the same as that of the first embodiment. Also, a pin standing substrate using the pins 41 is manufactured in the same manner as in the first embodiment using the same substrate body 21 as in the first embodiment. Therefore, also in the present modification, the same effects as those of the first embodiment can be obtained with respect to the pins, the pin standing method, and the method of manufacturing the pin standing substrate.

(Modification 2) Next, Modification 2 of Embodiment 1 will be described. Also in this modification, the shape of the pin, particularly the shape of the base end portion of the pin, is different from the pins 1 and 41 of the first embodiment and the first modification.

FIG. 11 shows a pin 51 according to this modification.
11A shows a view from the base end portion 54 side, FIG. 11B shows a front view, and FIG. 11C shows a view from the tip end portion 53 side. The pin 51 also includes an engaging portion 52, and a distal end portion 53 and a proximal end portion 54 extending from the engaging portion 52 in the opposite manner. The engaging portion 52 and the distal end portion 53 are the same as those in the first embodiment.
It has the same shape as the pin 1. On the other hand, the base end portion 54 has a substantially elliptical cross section with a minor axis of 0.4 mm and a major axis of 0.5 mm, a height of 1.05 mm in the direction of the axis AA ′, and a proximal end thereof (FIG. 11 (b) is chamfered.

Therefore, this pin 51 is also used in the first embodiment.
Similarly, the maximum dimension of the engaging portion 52 (the diameter of the engaging portion 52 =
0.7 mm) is the maximum dimension of the distal end 53 (diameter of the distal end 53 = 0.45 mm) and the maximum dimension of the proximal end 54 (0.
5 mm). The maximum dimension (0.5 mm) of the base end portion 54 is equal to the diameter of the distal end portion 53 (0.45 mm).
mm).

A pin setting jig 11 similar to that of the first embodiment.
When the pin 51 of the present modification is set up using
When the tip 53 side is inserted into the through hole 14 of the pin setting jig 11, the diameter of the tip 53 (0.45 mm)
Is smaller than the diameter (0.48 mm) of the distal end insertion hole 12, so that the distal end portion 53 is loosely inserted into the distal end insertion hole 12 as in the first embodiment. Further, the engaging portion 52 of the pin 51 engages with the chamfered portion 13 (see FIG. 2A).

On the other hand, the maximum dimension (0.5 mm) of the proximal end portion 54 of the pin 51 is the diameter of the distal end insertion hole 12 (0.
48 mm), the proximal end portion 54 is not inserted into the distal end insertion hole 12 as in the first embodiment (see FIG. 2B). For this reason, if the pin 51 is used to set the pin 51 on the pin setting jig 11, the tip end insertion hole 12 of the pin setting jig 11 is used in the pin setting step.
The pin 51 is easily and correctly inserted from the tip 53 side. In the pin insertion step, the pin stand jig 1
Since the pins 51 set to 1 protrude from the base end 54 side, the pin connection holes 23 of the board main body 21 are
Only the base end 54 can be reliably inserted. Therefore, in the pin 51 of the present modified example, the pin standing method using the same, and the method of manufacturing the pin standing substrate, the first embodiment is used.
The same effect can be obtained.

Next, a method of manufacturing the pin 51 will be described. First, at the same time as forming the substantially disk-shaped engaging portion 52 from the Kovar wire MT by a known press working,
A substantially cylindrical base end 53 having a base end chamfered is formed (see FIG. 4B). After that, similarly to the first embodiment, the chamfered base ends are pressed into the pressing surfaces P1A, P2A.
Are sandwiched between press dies P1 and P2 each having a substantially flat surface, and pressed to form a base end portion 54 (see FIG. 4C).
Then, the Kovar wire MT is cut to form the tip 53 (see FIG. 4D). Further, if a Ni-Au plating process is performed, the pin 51 is completed.

When a pin standing board is manufactured from the same board body 21 as in the first embodiment using the pins 51 of the present embodiment, the base ends of the base ends 54 of the pins 51 are chamfered. Therefore, it is easy to insert the base end portion 54 into the pin connection hole 23 of the board main body 21. That is, in the pin insertion step, the pin setting jig 11 on which the pins 51 are set is aligned with the substrate body 21, and the base end 54 of the pin 51 protruding from the pin setting jig 11 is inserted into the pin connection hole 23. In doing so (see FIG. 7), the base end portion 54 can be easily and reliably inserted into the pin connection hole 23 without damaging the pin connection hole 23.

(Modifications 3 and 4) Next, modifications 3 and 4 of the first embodiment will be described. Also in Modifications 3 and 4, the shape of the pin, particularly the shape of the base end of the pin, differs from the pins 1, 41, and 51 of Embodiment 1 and Modifications 1 and 2, respectively.

FIG. 12A shows a view from the base end portion 64 side in FIG.
FIG. 12B shows a front view, and FIG. 12C shows a view seen from the distal end portion 63 side. The pin 61 also includes an engaging portion 62 and a distal end portion 63 and a proximal end portion 64 extending from the engaging portion 62 in a reverse manner. The engaging portion 62 and the distal end portion 63 are the same as those of the first embodiment. It has the same shape as the pin 1. That is, the engaging portion 6
2 (0.7 mm) is equal to the diameter of the tip 63 (0.45 m
m). On the other hand, the base end portion 64 has a substantially cylindrical shape, and its diameter (diameter 0.5 mm) is equal to that of the distal end portion 6.
3 (0.45 mm in diameter) and the engagement portion 62
(0.7 mm in diameter).

Next, with respect to the pin 71 of the fourth modification,
FIG. 13 (a) is a view from the base end portion 74 side, and FIG.
FIG. 13B is a front view, and FIG. 13C is a view as viewed from the distal end portion 73 side. The pin 71 also includes an engaging portion 72, and a distal end portion 73 and a proximal end portion 74 that extend from the engaging portion 72 in the opposite manner, and the engaging portion 72 and the distal end portion 73 of the first embodiment. It has the same shape as the pin 1. On the other hand, the base end 7
4 has a substantially elliptical column shape with a minor axis of 0.45 mm and a major axis of 0.5 mm. That is, the maximum dimension (0.5 mm) of the base end 74 in the direction orthogonal to the axis AA ′ is the tip 73 (diameter 0.4).

mm) is smaller than the diameter (0.48 mm) of the distal end insertion hole 12, so that both the distal ends 63 and 73 are loosely inserted into the distal end insertion hole 12 as in the first embodiment.
Further, the engaging portions 62 of the pins 61 and 71 are both engaged with the chamfered portion 13 (see FIG. 2A).

On the other hand, the maximum size (0.5 mm) of the proximal ends 64 and 74 of these pins 61 and 71 is larger than the diameter (0.48 mm) of the distal end insertion hole 12. Furthermore, the dimension near the base end 64A, 74A is also the maximum dimension. Therefore, similarly to the first embodiment, neither the base end portion 64 nor 74 is inserted into the front end portion insertion hole 12 (see FIG. 2B). For this reason, when the pins 61 and the like are set up on the pin setting jig using the pins 61 and 71, the front end insertion holes 12 of the pin setting jig 11 are inserted from the front end 63 and the like of the pins 61 and the like. Easily and correctly pin 61
Etc. are inserted. When the pins 61 and the like are set up on the pin setting jig 11, only the base end 64 and the like protrude from the pins 61 and the like. Therefore, when the pins 61 and the like are inserted into the pin connection holes 23 of the substrate body 21, Only the base end 64 or the like can be reliably inserted.

Therefore, in the pins 61 and 71, the pin setting method using the pins 61 and 71, and the method of manufacturing the pin setting board, the same effects as those of the first embodiment can be obtained. In addition,
Each of these pins 61 and 71 is formed from a Kovar wire by a known press working. That is, unlike the case of manufacturing the pins 141 and 51 of the first embodiment and the first and second modifications, there is no need to press the mold separately or separately with a punch to form the base end. ,
Its manufacture is even easier.

As a method of fixing the pin to the substrate body, the base end of the pin and the shape of the pin connection hole may be adjusted, and the base end of the pin may be pressed into the pin connection hole and fixed. . Further, a method of providing a through hole as a pin connection hole in the substrate main body, inserting a pin having a base end longer than the thickness of the substrate main body, crushing a portion protruding from the substrate main body with a press, and fixing the same is also included. In addition to these methods, a solder material may be used for fixing. The pin connection hole is not limited to a through hole penetrating the substrate body, and may be a bottomed hole opened only on the main surface of the substrate.

Further, in the above embodiment, the shapes of the engaging portion 2 and the like and the tip portion 3 and the like are both substantially cylindrical, but these shapes are substantially elliptical, substantially elliptical, The shape can be appropriately changed to a polygon or other shapes. that time,
