Embodiment
Hereinafter with reference to correlative type, coil and manufacture method thereof according to a kind of tool pin of preferred embodiment of the present invention are described, wherein components identical will be illustrated with identical reference marks.
Please refer to shown in Fig. 1, Fig. 2 A to Fig. 2 F, a kind of manufacture method with coil of pin of preferred embodiment of the present invention comprises the following steps:
In step S11, on substrate 1, form at least one conductive projection S (shown in Fig. 2 B) with at least one paired pin 11.Particularly, on substrate 1, cover template 2 (shown in Fig. 2 A), those holes 21 respectively corresponding those pin 11 ends with at least one or a plurality of hole 21.The shape of those holes 21 can be circle, polygon, ellipse, regular shape or irregularly shaped.Then, conductive material in modes such as print process, completion method or screening methods, form conductive projection S in those holes 21, and this conductive projection S is contacted with this pin.This conductive projection S preferably sticks together, is attached at those pin 11 ends.
In addition, in the present embodiment, this substrate 1 can utilize one-body molded making with this each paired pin 11, and this substrate 1 is also unrestricted with the material of this each paired pin 11, be a metal or an alloy, and this substrate 1 more can be a steel plate.The material of this template 2 then can be a metal or an alloy, is example with a steel plate then at this.But this conductive projection S material can be tin cream, tin ball thermal deformation material or easy moulding material etc.
In step S12, at least one coil body C two ends are placed respectively on those pin 11 ends, and this coil body C two ends are contacted with corresponding this conductive projection S respectively.More very it also can place substrate 1 one to have on the tool 3 of a plurality of grooves 31 (shown in Fig. 2 C) earlier, coil body C is placed those grooves 31 (shown in Fig. 2 D) again, so that coil body C two ends can be accurately and rapidly to being positioned on the pin 11.So, can increase substantially reliability and the qualification rate that coil body C engages with pin 11.In addition, the spacing of this each paired pin 11 is preferably the coiling diameter greater than this coil body C.
In step S13, change this conductive projection S shape in modes such as heating, ultrasonic waves methods, this coil body C and this pin 11 are linked together by this conductive projection S.Particularly, the aforementioned tool 3 that is mounted with coil body C, conductive projection S and pin 11 is delivered to heating in the heater 4,, and engage this coil body C end and this each pin 11 simultaneously so that deformation (as changing molten condition into) takes place this conductive projection S.After treating that conductive projection S after this deformation solidifies, promptly finish engaging of this coil body C end and this each pin 11.Aforementioned heater 4 can be baking box, heat gun, heater or infrared furnace (IR stove).At this moment, this coil body C is fixed on this substrate 1.
In addition, when this conductive projection S is in molten condition, this conductive projection S can only be adsorbed near this coil body C and this each pin 11 contacts site because of the capillarity effect, and then this conductive projection S of fusion can not overflow or pollute this each pin 11, this coil body C or other parts, also can improve the bond strength and the reliability of this coil body C and this each pin 11, further can obtain to have the coil of the tool pin of good homogeneity and qualification rate, and be beneficial to the back segment assembling.
Afterwards in step S14, with pin 11 not the end of connecting coil body C on substrate 1, separate, can obtain the coil (please refer to Fig. 2 F) of tool pin.When substrate 1 is provided with many group pins 11, can be a large amount of, stable and produce the coil of tool pin exactly.
In addition, because formed conductive projection S can be subjected to hole 21 size restrictions of template 2, and the use amount that makes each conductive projection S is fixed and is moderate, therefore when conductive projection S fusion deformation, do not have excessive, problem such as overflow, more can not pollute the other parts of elements such as this pin 11, this substrate 1 or this coil body C.And this coil can be used as the coil that built-in inductor is used or non-built-in inductor is used.
Also have, please refer to Fig. 1, in the aforementioned tool lead-foot-line circle manufacturing method, abovementioned steps S11 and S12 also can change to step S15 and S16.In step S15, on substrate 1, at least one coil body C two ends are stacked and placed on respectively on those pin 11 ends with at least one paired pin 11.In step S16,, form at least one conductive projection S again at coil body C end and pin 11 mutual stacked places.Afterwards, carry out abovementioned steps S13 and S14 again, and finish the manufacturing of tool pin coil.
In sum, because of forming a conductive materials in this coil body or this pin junction by mode of printing, change this conductive materials shape again, to engage this coil body and this pin according to a kind of coil and manufacture method thereof of the present invention with pin.Compared with prior art, the present invention need not use extra spot welding machine or special installation, only use this template, this tool and device (as heater) in order to change this conductive materials shape, can engage this coil body and this pin easily and accurately, and can be fit to a large amount of productions, and further reduce manufacturing cost.Because this template thickness and this bore hole size can be accurately and are controlled each conductive materials size equably, so can be easy to the effect of management and control production quality.In addition, when this conductive materials changes shape in heating, meeting only is adsorbed near this coil body and this pin contact site because of capillarity, not only can not overflow or pollute this pin, this coil body or other parts, also can improve the bond strength and the reliability of this coil body and this pin, further can obtain to have the tool pin coil of good homogeneity and qualification rate, and be beneficial to the back segment assembling.
