The installation method of installing to printed base plate 30 (two-sided through hole printed base plate) for rotary type electric element 1 shown in Figure 1 describes.
Shown in Fig. 7 (a), on printed base plate 30, form the through hole 31 that runs through to lower surface 30b from upper surface 30a.Shown in Fig. 7 (a), on the inwall 31a of through hole 31, be formed with conductive part 32 by electroplating to wait.Conductive part 32 extends to the upper surface 30a and the lower surface 30b of printed base plate 30, is formed with pad respectively.Through hole 31 is arranged at the position corresponding with the splicing ear portion 17,18 that constitutes rotary type electric element 1.As shown in Figure 8, the hole shape of through hole 31 is the curved surface shape, particularly, is circular shape or substantially elliptical shape.The aperture of through hole 31 (diameter) is about 1.0～1.1mm.The aperture of through hole 31 is certain from the upper surface 30a side of printed base plate 30 to lower surface 30b side for example.In addition, the conductive part (pad) 32 that exposes at the upper surface 30a and the lower surface 30b of printed base plate 30 is shaped as ring-type.Integrally formed wiring pattern 40 on this conductive part 32.
In the operation shown in Fig. 7 (b), possesses the guide plate (guide plate) 33 of the through hole 33a in the aperture bigger in the setting of the upper surface 30a of printed base plate 30 side than the aperture of through hole 31.Secondly, in the operation of Fig. 7 (c), coating paste scolder 34 in the through hole 33a of guide plate 33.And, squeegee 41 is moved to the direction of arrow, paste scolder 34 is filled (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), splicing ear portion 17,18 insertions that constitute rotary type electric element 1 are filled with in the through hole 31 of paste scolder 34.Like this, shown in Fig. 7 (f), the part of 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 the through hole 31, implement the reflow soldering operation.The heating-up temperature that reflow ovens produced is about 240～260 ℃.Here, the scolder 35 that melts by heating, attracted to because of capillarity between the inwall 31a of splicing ear portion 17,18 and through hole 31, shown in Fig. 7 (h), between the conductive part (pad) 32 of the upper surface 30a of printed base plate 30 and lower surface 30b and side, can form good solder fillet 36 in the splicing ear portion 17,18 at the place, top and the bottom of through hole 31.
The splicing ear portion 17,18 of rotary type electric element 1 that constitutes present embodiment has for making the shape of metallic plate 3,6 distortion: the paste scolder 34 that is used for being filled into through hole 31 is from the portion that extrudes 37 that through hole 31 is extruded in right amount; And be used for attraction portion 38 between the inwall 31a of through hole 31 that scolder 35 with heat fused was attracted to and formed conductive part 32.
As shown in Figure 3, Figure 4, splicing ear portion the 17, the 18th is formed metallic plate 3,6 bending machining the shape of its outer peripheral face 17a, 18a by curved surface, extrude portion 37 and be made of the front end 17b of splicing ear portion 17,18, the front end of 18b, attraction portion 38 is made of outer peripheral face 17a, the 18a of splicing ear portion 17,18.
Here, the splicing ear portion the 17, the 18th that the metallic plate shifting ground is formed by the thickness of one piece of metallic plate, tabular, mechanical strength is low.Have again, owing to thickness T 1 (with reference to Fig. 4) is as thin as about 0.15～0.2mm, so the paste scolder 34 that can not will fill in through hole 31 by the insertion of splicing ear portion is extruded fully.Therefore, in the present embodiment, as mentioned above like that with metallic plate 3,6 bending machining, improve the mechanical strength of splicing ear portion 17,18, and can become the portion of extruding 37 by front end 17b, the 18b that makes circular or substantially elliptical and come effectively paste scolder 34 to be extruded in right amount to foreign side in through hole 31.Especially, by in the splicing ear portion 17,18 of present embodiment, inboard in the outside curve portion 51 of outer peripheral face 17a, 18a with curved surface possesses inside bend portion 50, thereby only form small space part 50b, 50c, and as the portion that extrudes 37 of paste scolder 34 is played a role effectively at front end 17b, the 18b of splicing ear portion 17,18.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 paste scolder 34 at first.And, only has small space part 50b at the front end 50d of inside bend portion 50, when the front end 50d with inside bend portion 50 extruded paste scolder 34, paste scolder 34 was difficult to enter in the space part 50b, and the front end 50d of available inside bend portion 50 extrudes paste scolder 34 effectively.
And, owing between the inwall 31a of curved outer peripheral face 17a, the 18a of the conduct attraction portion 38 of splicing ear portion 17,18 and the through hole 31 that hole shape is the circular shape, can in broad range, form the roughly minim gap of certain intervals (about 0.1～0.2mm), so the scolder of extruding under the state that has melted 35 is attracted effectively by capillarity between the inwall 31a of outer peripheral face 17a, the 18a of conduct attraction portion 38 and through hole 31, can form solder fillet 36 such shown in Fig. 7 (h) well.
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 hole shape for the gap between the inwall 31a of the through hole 31 of round shape roughly more effectively forms small roughly certain intervals, therefore, can more effectively form good solder fillet 36.
In the present embodiment, outer peripheral face 17a, the 18a that forms by curved surface account for splicing ear portion 17,18 around whole more than 60% (area ratio), be preferably more than 80%.
In addition, as Fig. 3, shown in Figure 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 the outside (outer peripheral face 17a, 18a direction), form the solder fillet 36 of better and modest size.
As mentioned above, by using the rotary type electric element 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, rotary type electric element shown in Figure 11 and rotary type electric element 1 parts in addition together can be installed on the 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 for the deterioration of the installation strength of the rotary type electric element 1 of present embodiment and other element etc.
Have, the machining shape of splicing ear portion 17,18 shown in Figure 3 is compared with the machining shape of other execution mode that illustrates later, is more suitable for forming good solder fillet 36, becomes better shape again.
In addition, the shape of the splicing ear portion 17,18 that formed by curved surface of outer peripheral face 17a, 18a also can be the shape beyond Fig. 3～shape shown in Figure 5.For example, though with metallic plate 3,6 from the coiling center laterally whirlpool shape ground bending machining also can form roughly cylindric outer peripheral face 17a, 18a or the substantially elliptical shape.But, in this case, need the plate part of bending machining to become the shape that the mind-set folk prescription stretches out more longways from reel.Though be the figure that describes for alternate manner, need become the part that makes mark shown in Figure 11 22 and further on directions X, extend such shape more longways.Therefore, can think to compare and be difficult to use mould etc. to carry out bending machining accurately with processing method shown in Figure 6.In addition, with Fig. 1, shown in Figure 2 a plurality of splicing ear portion 17, after each metallic plate being inlayed under with flat state be formed in the matrix 8, under the situation that each metallic plate bending machining is formed, as mentioned above, under the mode of the metallic plate that is wound on the form that the direction in flat state lower edge extends more longways with bending machining, must make the interval of each metallic plate bigger.Relative with it, if the shape of Fig. 3 splicing ear extremely illustrated in fig. 5 portion 17, then can use the metallic plate 3,6 of the writing board shape that give prominence to shortly the mind-set both sides from the stretching out of metallic plate 3,6 to come simply and suitably to form outer peripheral face 17a, 18a splicing ear portion 17,18 as curved surface by bending machining shown in Figure 6, be easy to make 17,18 thin spaceizations of each splicing ear portion so become the shape of Fig. 3 splicing ear portion 17,18 extremely shown in Figure 5, can realize the miniaturization of electric component.
In the rotary type electric element 1 of present embodiment, metallic plate 3,6 is inlayed 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 shaping in matrix 4,8.And though the part of metallic plate 3,6 is stretched out and become 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 that forms on metallic plate 3,6.Therefore, the part of bend also is one piece of metal sheet 3,6, so can be in the part of bend with metallic plate 3,6 suitably downward direction bendings.
In the present embodiment, splicing ear portion 17,18 forms in the whole regional extent of reflow soldering continuously.That is, splicing ear portion 17,18 is long to length dimension L2, L3 (Fig. 7 (g) (h)) that the length dimension L1 (with reference to Fig. 5) that stretches out direction (diagram Y direction) forms than reflow soldering zone.Therefore, do not hinder the moving of scolder 35 of fusing, can carry out soldering more reliably.
In addition, in the present embodiment, whole splicing ear portions 17,18 are preferably formed by same configuration.
In addition, in execution mode shown in Figure 3, be formed with rib 3c, the 6c of reinforcement usefulness at the central portion that stretches out direction of the metallic plate except that splicing ear portion 17,18 3,6.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 (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 forming its front end face and section shown in Fig. 9 (c) like that is circinate rod shape.
Figure 11 represents to constitute the metallic plate 71 crooked preceding states of splicing ear portion 70.As shown in figure 11, metallic plate 71 is made of with the first curved tabs portion 21 that is positioned at Width (diagram directions X) both sides and the second curved tabs portion 22 central board 20.At first, between the central board 20 and the first curved tabs portion 21 along upwardly extending A line is overlapped in the first curved tabs portion, 21 recessed foldings (arrow C direction) on the central board 20 with the first curved tabs portion 21 in Y side.Then, between the central board 20 and the second curved tabs portion 22 along upwardly extending B line is overlapped in the second curved tabs portion, 22 recessed foldings (arrow D direction) in the first curved tabs portion 21 with the second curved tabs portion 22 in Y side.Like this, central board 20, the first curved tabs portion 21,22 threes of the second curved tabs portion is overlapping on thickness direction.At this moment, between the central board 20 of thickness direction and the first curved tabs portion 21 and the situation that does not form the gap between the first curved tabs portion 21 and the second curved tabs portion 22 as far as possible, more satisfactory on the mechanical strength of guaranteeing splicing ear portion 17.Have again, at front end face that makes splicing ear portion 17 and section is under the circinate situation, as mentioned above, when making the first curved tabs portion 21 that is positioned at central board 20 both sides and the second curved tabs portion, 22 overlapping formation, then because the effect of the first curved tabs portion 21 of pushing initial bending is played by the second curved tabs portion 22, so can guarantee that gap and the gap between the first curved tabs portion 21 and the second curved tabs portion 22 between the central board 20 and the first curved tabs portion 21 are less.
In addition, in execution mode shown in Figure 9, be formed with the rib 71c of reinforcement usefulness at the central portion that stretches out direction (Y direction) of the metallic plate except splicing ear portion 70 71.But the formation of rib 71c not necessarily.
The front end face of the 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, also can be front end face and section shape shown in Figure 10.For example, when becoming shape shown in Figure 10,, the second curved tabs portion 22 is got final product from the ground bending of the recessed folding of B line as long as the first curved tabs portion 21 shown in Figure 11 is crooked from the protruding folding of A 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 the front end face and the section that are used for Fig. 9 (c) is illustrated is that circinate size is stipulated, 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 the bending direction that makes A line, B line with above-mentioned opposite, then be zigzag roughly.
In the present embodiment, the thickness T 1 of metallic plate 71 is about 0.15～0.2mm.Therefore, in that metallic plate 71 is crooked overlapping so that its aggregate thickness T2 when becoming the whirlpool shape as Fig. 9 (c) is about 0.5～0.7mm.In addition, the width dimensions T3 of splicing ear portion 70 is about 0.8～0.9mm.The ratio of T2/T3 is preferably near 1.In the present embodiment, as mentioned above, the aggregate thickness T2 that is fit to formation splicing ear portion 17 is 0.5～0.7mm, and the ratio of T2/T3 is the bar-shaped splicing ear portion 70 of 0.8～0.9mm.
Make the front end face of splicing ear portion 70 form the whirlpool shape as shown in Figure 7 by reaching, and it is bar-shaped that splicing ear portion 17 is become rightly, can improve mechanical strength as Fig. 9 (c).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 as the front end of splicing ear portion 17, can extrude the paste scolder 34 of filling from through hole 31 effectively in right amount in through hole 31.
In addition, the bight that becomes attraction portion 38 is four angles of splicing ear portion 70 peripheries.But, can not form the bight sometimes according to bending direction of metallic plate 71 etc. yet.For example, shown in Fig. 9 (c), between the 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 the interval narrow down, and suitably play a role as attraction portion 39.
At front end face shown in Fig. 9 (c) and section is under the situation of whirlpool shape ground formation, 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 the scolder 35 that melts more reliably.In addition, and in the mode that becomes 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 the periphery in splicing ear portion 70 is occurred only is a place.Near seam, and the inwall 31a of through hole 31 between the attraction of the scolder 35 that melts be easy to descend, so preferably the seam that occurs in periphery is few more good more.
As Fig. 9 (c) and shown in Figure 10, splicing ear portion 70 forms in the mode of overlapping three pieces of metallic plates on thickness direction.Preferably form bar-shaped in mode at overlapping metallic plate more than three pieces on the thickness direction.In two pieces,, paste scolder 34 can not be extruded from through hole 31 fully even will can not obtain enough mechanical strengths so that the metallic plate that the thickness about 0.15～0.2mm forms is overlapping.
