As shown in Fig. 7 (a), on printed base plate 30, form the through hole 31 running through to lower surface 30b from upper surface 30a.As shown in Fig. 7 (a), on the inwall 31a of through hole 31, by electroplating to wait, be formed with conductive part 32.Conductive part 32 extends to upper surface 30a and the lower surface 30b of printed base plate 30, is formed with respectively pad.Through hole 31 is arranged at the position corresponding with the splicing ear portion 17,18 that forms rotary electric component 1.As shown in Figure 8, the hole shape of through hole 31 is curved surface shape, particularly, is circular shape or substantially elliptical shape.The aperture of through hole 31 (diameter) is 1.0～1.1mm left and right.The aperture of through hole 31 is for example certain from the upper surface 30a side of printed base plate 30 to lower surface 30b side.In addition the conductive part (pad) 32 exposing at upper surface 30a and the lower surface 30b of printed base plate 30, be shaped as ring-type.On this conductive part 32, be integrally formed wiring pattern 40.
In the operation shown in Fig. 7 (b), in the setting of the upper surface 30a of printed base plate 30 side, possesses the guide plate (guide plate) 33 of the through hole 33a in the aperture larger than the aperture of through hole 31.Secondly, in the operation of Fig. 7 (c), in the through hole 33a of guide plate 33, apply paste scolder 34.And, squeegee 41 is moved to the direction of arrow, paste scolder 34 is filled to (Fig. 7 (d)) from the through hole 33a of guide plate 33 to the through hole 31 of printed base plate 30.And, remove guide plate 33.
Secondly, in the operation of Fig. 7 (e), the splicing ear portion 17,18 that forms rotary electric component 1 is inserted and is filled with in the through hole 31 of paste scolder 34.Like this, as shown in Fig. 7 (f), a part for paste scolder 34 is extruded downwards by the insertion of splicing ear portion 17,18.
Then,, in the operation of Fig. 7 (g), under the state that splicing ear portion 17,18 is inserted in through hole 31, implement reflow soldering operation.The heating-up temperature that reflow ovens produces is 240～260 ℃ of left and right.Here, by heating the scolder 35 melting, because capillarity attracted between splicing ear portion 17,18 and the inwall 31a of through hole 31, as shown in Fig. 7 (h), between the upper surface 30a of printed base plate 30 and the conductive part (pad) 32 of lower surface 30b and the side in the splicing ear portion 17,18 at the place, top and the bottom of through hole 31, can form good solder fillet 36.
The splicing ear portion 17,18 that forms the rotary electric component 1 of present embodiment is the shape that makes metallic plate 3,6 distortion, has: for the portion that extrudes 37 that the paste scolder 34 that is filled into through hole 31 is extruded in right amount from through hole 31; With for the scolder of heat fused 35 being attracted and forming the suction unit 38 between the inwall 31a of through hole 31 of conductive part 32.
As shown in Figure 3, Figure 4, splicing ear portion the 17, the 18th, by metallic plate 3,6 bending machining and by the shape of its outer peripheral face of Surface forming 17a, 18a, extrude portion 37 and consist of the front end 17b of splicing ear portion 17,18, the front end of 18b, suction unit 38 consists of outer peripheral face 17a, the 18a of splicing ear portion 17,18.
Here, the splicing ear portion the 17, the 18th that does not make metallic plate shifting ground be formed by the thickness of one piece of metallic plate, tabular, mechanical strength is low.Have again, because thickness T 1 (with reference to Fig. 4) is as thin as 0.15～0.2mm left and right, so can not will extrude fully at the paste scolder 34 of through hole 31 interior fillings by the insertion of splicing ear portion.Therefore, in the present embodiment, as described above by metallic plate 3,6 bending machining, improve the mechanical strength of splicing ear portion 17,18, and can come effectively paste scolder 34 to be extruded in right amount from through hole 31Nei Xiang foreign side by making front end 17b, the 18b of circular or substantially elliptical become the portion of extruding 37.Especially, in the splicing ear portion 17,18 in present embodiment, in the inner side of outside curve portion 51 with outer peripheral face 17a, the 18a of curved surface, possesses inside bend portion 50, thereby only form small space part 50b, 50c at front end 17b, the 18b of splicing ear portion 17,18, and as the portion that extrudes 37 of paste scolder 34 is played a role effectively.In addition, in the present embodiment, the front end 50d of inside bend portion 50 is more outstanding than the front end 51d of outside curve portion 51, and the front end 50d of inside bend portion 50 plays a role as the portion that extrudes 37 that contacts at first paste scolder 34.And, at the front end 50d of inside bend portion 50, only there is small space part 50b, when the front end 50d with inside bend portion 50 extrudes paste scolder 34, paste scolder 34 is difficult to enter in space part 50b, and the front end 50d of available inside bend portion 50 extrudes paste scolder 34 effectively.
And, between the inwall 31a of the through hole 31 that is circular shape due to curved outer peripheral face 17a, 18a as suction unit 38 in splicing ear portion 17,18 and hole shape, can in broad range, form the roughly minim gap of certain intervals (0.1～0.2mm left and right), so the scolder having melted 35 of extruding under state is effectively attracted by capillarity between outer peripheral face 17a, 18a as suction unit 38 and the inwall 31a of through hole 31, can form well solder fillet 36 such shown in Fig. 7 (h).
Especially, in the present embodiment, as shown in Figure 3, Figure 4, can be with the cylindric shape that forms outer peripheral face 17a, 18a roughly, like this, can make and inwall 31a that hole shape is the through hole 31 of round shape roughly between gap more effectively form small roughly certain intervals, therefore, can more effectively form good solder fillet 36.
In the present embodiment, more than 60% (area ratio) of surrounding's integral body that accounts for splicing ear portion 17,18 by outer peripheral face 17a, the 18a of Surface forming, is preferably more than 80%.
In addition, as shown in Fig. 3, Fig. 5, in inside bend portion 50, from the front end 50d of inside bend portion 50 laterally the front end 51d direction of bend 51 be formed with inclined plane 51e, 50f, like this, paste scolder 34 can be expressed into effectively to outside (outer peripheral face 17a, 18a direction), form the solder fillet 36 of better and modest size.
As mentioned above, by using the rotary electric component 1 of present embodiment, reflow soldering securely in the through hole 31 that can form on printed base plate 30, can improve installation reliability.
In addition in the present embodiment, the rotary electric component shown in Fig. 11 and the parts beyond rotary electric component 1 together can be arranged on printed base plate 30 with reflow soldering.Therefore, commonization of reflow process can be realized, simple installation method can be realized.In addition,, by commonization of reflow process, can suppress deteriorated etc. for the rotary electric component 1 of present embodiment and the installation strength of other element.
Have, the machining shape of the splicing ear portion 17,18 shown in Fig. 3 is compared with the machining shape of other execution mode illustrating below, is more suitable for forming good solder fillet 36, becomes more preferably shape again.
In addition, outer peripheral face 17a, 18a can be also the shapes in addition of shape shown in Fig. 3～Fig. 5 by the shape of the splicing ear portion 17,18 of Surface forming.For example, though by metallic plate 3,6 from coiling center laterally whirlpool shape ground bending machining also outer peripheral face 17a, 18a can be formed to roughly cylindric or substantially elliptical shape.But, in this case, need the plate part of bending machining to become the shape that mind-set folk prescription stretches out more longways from reel.Although be the figure describing for alternate manner, the part that need to become the mark 22 making shown in Figure 11 is further extended more longways such shape on directions X.Therefore, can think to compare with the processing method shown in Fig. 6 and be difficult to use mould etc. to carry out accurately bending machining.In addition, by a plurality of splicing ear portion 17 shown in Fig. 1, Fig. 2, after in each metallic plate being inlayed under with flat state be formed into matrix 8, in the situation that each metallic plate bending machining is formed, as mentioned above, under the mode of metallic plate that is wound on the form of extending more longways along a direction under flat state by bending machining, must make the interval of each metallic plate larger.In contrast, if the shape of Fig. 3 splicing ear extremely illustrated in fig. 5 portion 17, can with mind-set both sides from the stretching out of metallic plate 3,6 shorter the metallic plate 3,6 of the writing board shape given prominence to by the bending machining shown in Fig. 6, come simply and suitably to form the splicing ear portion 17,18 that outer peripheral face 17a, 18a are curved surface, so become the shape of the splicing ear portion 17,18 shown in Fig. 3 to Fig. 5, be easy to make 17,18 thin spaces of each splicing ear portion, can realize the miniaturization of electric component.
In the rotary electric component 1 of present embodiment, metallic plate 3,6 is inlayed to shaping in matrix 4,8.In the present embodiment, the metallic plate 3,6 of inlaying the part of shaping is that one piece of Boping is tabular, so can securely metallic plate 3,6 be inlayed to shaping in matrix 4,8.And although a part for metallic plate 3,6 is stretched out and becomes splicing ear portion 17,18 to the foreign side of matrix 4,8, splicing ear portion 17,18 forms in free end side by the bend forming on metallic plate 3,6.Therefore, the part of bend is also one piece of metal sheet 3,6, so can in the part of bend, by metallic plate 3,6, suitably downward direction is crooked.
In the present embodiment, splicing ear portion 17,18 forms continuously in the whole regional extent of reflow soldering.That is length dimension L2 from reflow soldering region to the length dimension L1 (with reference to Fig. 5) that stretches out direction (diagram Y-direction), L3 (Fig. 7 (g) (h)) that, splicing ear portion 17,18 forms than are long.Therefore, do not hinder the movement of the scolder 35 of fusing, can carry out more reliably soldering.
In addition, in the present embodiment, whole splicing ear portions 17,18 are preferably formed by same configuration.
In addition, in the execution mode shown in Fig. 3, at the central portion that stretches out direction of the metallic plate 3,6 except splicing ear portion 17,18, be formed with rib 3c, the 6c of reinforcement use.But the formation of rib 3c, 6c not necessarily.
In Fig. 9, represent the shape of the splicing ear portion 70 of other execution mode (the second execution mode).As shown in Figure 9, in the present embodiment, splicing ear portion 70, flat metallic plate 71 stretches out direction (diagram Y-direction) bending along it, and as shown in Fig. 9 (c), forming its front end face and section is circinate clavate shape.
Figure 11 represents the state before metallic plate 71 bendings of formation splicing ear portion 70.As shown in figure 11, metallic plate 71 consists of with the first curved tabs portion 21 and the second curved tabs portion 22 that are positioned at Width (diagram directions X) both sides central board 20.First, the A line that extend in the Y direction on edge between central board 20 and the first curved tabs portion 21, by the first recessed folding of curved tabs portion 21 (arrow C direction), is overlapped in the first curved tabs portion 21 on central board 20.Then, the B line that extend in the Y direction on edge between central board 20 and the second curved tabs portion 22, by the second recessed folding of curved tabs portion 22 (arrow D direction), is overlapped in the second curved tabs portion 22 in the first curved tabs portion 21.Like this, central board 20, the first curved tabs portion 21, the second 22 threes of curved tabs portion is overlapping on thickness direction.Now, between the central board 20 of thickness direction and the first curved tabs portion 21 and do not form as far as possible the situation in gap between the first curved tabs portion 21 and the second curved tabs portion 22, more satisfactory in the mechanical strength of guaranteeing splicing ear portion 17.Have again, making front end face and the section of splicing ear portion 17, be in circinate situation, as mentioned above, by making to be positioned at the first curved tabs portion 21 of central board 20 both sides and second curved tabs portion 22 is overlapping while forming, due to the second curved tabs portion 22, play the effect of the first curved tabs portion 21 of pressing initial bending, so can guarantee that gap and the gap between the first curved tabs portion 21 and the second curved tabs portion 22 between central board 20 and the first curved tabs portion 21 are less.
In addition,, in the execution mode shown in Fig. 9, at the central portion that stretches out direction (Y-direction) of the metallic plate 71 except splicing ear portion 70, be formed with the rib 71c of reinforcement use.But the formation of rib 71c not necessarily.
The front end face of splicing ear portion 70 in the execution mode of Fig. 9 and the shape of section are not limited to Fig. 9 (c).For example, can be also the front end face shown in Figure 10 and section shape.For example, when the shape becoming shown in Figure 10, if the first curved tabs portion 21 shown in Figure 11 is crooked from the protruding folding of A line ground, the second curved tabs portion 22 is crooked from the recessed folding of B line ground.But, the width dimensions (towards the length of directions X) of central board 20, the first curved tabs portion 21 and the second curved tabs portion 22 shown in Figure 11, by being that circinate size is stipulated for making front end face and section that Fig. 9 (c) illustrates, so meet the suitable Rack size of front end face and section shape ground.As shown in figure 10, splicing ear portion 70 is roughly S shape, if but make the bending direction of A line, B line contrary to the above, be zigzag roughly.
In the present embodiment, the thickness T 1 of metallic plate 71 is 0.15～0.2mm left and right.Therefore, metallic plate 71 is crooked overlapping so that its aggregate thickness T2 while becoming whirlpool shape as Fig. 9 (c) is 0.5～0.7mm left and right.In addition, the width dimensions T3 of splicing ear portion 70 is 0.8～0.9mm left and right.The ratio of T2/T3 preferably approaches 1.In the present embodiment, as mentioned above, the aggregate thickness T2 that be applicable to form splicing ear portion 17 is 0.5～0.7mm, and the ratio of the T2/T3 bar-shaped splicing ear portion 70 that is 0.8～0.9mm.
By as Fig. 9 (c) and make as shown in Figure 7 the front end face of splicing ear portion 70 form whirlpool shape, and it is bar-shaped to make splicing ear portion 17 become rightly, can improve mechanical strength.And, can increase the aggregate thickness T2 (with reference to Fig. 9 (c)) of the portion that extrudes 37 of thickness direction (Z direction).Its result, by the portion that extrudes 37 of the front end as splicing ear portion 17, can extrude the paste scolder 34 of filling in through hole 31 from through hole 31 effectively in right amount.
In addition the bight that, becomes suction unit 38 is four angles of splicing ear portion 70 peripheries.But, according to bending direction of metallic plate 71 etc., sometimes can not form bight yet.For example, as shown in Fig. 9 (c), between central board 20 and the first curved tabs portion 21, form the protuberance (position of symbol 39) more outstanding than bight (position of symbol 38).This type of protuberance also make and the inwall 31a of through hole 31 between interval narrow down, and suitably play a role as suction unit 39.
In the situation that the front end face shown in Fig. 9 (c) and section be whirlpool shape form, can make the front end face of splicing ear portion 70 and the hole shape that section is close to rounded through hole, can attract more reliably fusing scolder 35.In addition, and to become the mode of the front end face shown in Figure 10 and section shape, metallic plate 71 bendings are compared, crooked by become whirlpool shape ground as Fig. 9 (c), the seam that can make the periphery in splicing ear portion 70 occur is only a place.Near seam, and the inwall 31a of through hole 31 between the attraction of the scolder 35 that melts be easy to decline, so the seam preferably occurring in periphery is more few better.
As shown in Fig. 9 (c) and Figure 10, splicing ear portion 70 forms in the mode of overlapping three pieces of metallic plates on thickness direction.Preferably the mode with overlapping more than three pieces metallic plate on thickness direction forms bar-shaped.In two pieces, even if the metallic plate that the thickness with 0.15～0.2mm left and right is formed is overlapping, can not obtain enough mechanical strengths, paste scolder 34 can not be extruded from through hole 31 fully.
