Description

Magnetic coil welding method
Technical field
The present invention relates to a kind of electronic component soldering method, more particularly to a kind of magnetic coil welding method.
Background technology
The patent of invention of existing Patent No. ZL201110162314.8 discloses a kind of welding method of magnetic coil, Include the following steps:Magnetic coil with several the end of a thread is provided;Electric connecting part equipped with several conduction regions is provided;There is provided one Radium-shine laser equipment;One welding equipment is provided;The end of a thread is aligned one by one with conduction region, the end of a thread one section of definition corresponding with conduction region For welding section, the coat of paint of the radium-shine laser equipment removal welding section;The welding section of the end of a thread is welded in using welding equipment and is led In electric area.Due in advance removing welding section coat of paint, in final welding process, welding section is not susceptible to deformation, to ensure The end of a thread good tensile strength.But surface labeling type electronic element need to usually be heated through reflow soldering, therefore this method In the presence of the unreliable hidden danger of welding:After welding need in further brush tin on solder joint, if soldered magnetic coil is heated again, After tin can be heated to melt to be flowed around, there is even tin short circuit hidden danger between adjacent welds, also, tin is lost in, it is welded on conduction region The end of a thread be easy detached with conduction region due to own tension, so as to cause product open a way;If after welding, brush tin, solder joint be not reliable Property it is low, the end of a thread be easy from conduction region be detached from.
Invention content
For overcome the deficiencies in the prior art, it is high, still reliable through solder joint when high temperature to provide a kind of production efficiency by the present invention Magnetic coil welding method.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of magnetic coil welding method, includes the following steps:(a)An insulating base is provided, the insulating base includes Several side walls and a bottom wall, several side walls and bottom wall form a storage tank, and insulating base is provided with several mutual in side wall The solder bath separated, further includes several conducting terminals for being fixed on side wall, and the conducting terminal has the weldering for being exposed to solder bath Connect plane;(b)Holder with an at least fixing groove is provided, the insulating base is fixed on fixing groove;(c)If providing has The magnetic coil of dry lead, the magnetic coil are contained in storage tank;(d)Lead is placed in solder bath, lead is made to be located at weldering It connects above plane, it is further comprising the steps of:(e)Lead and welding plane welding are integrated by a plumb joint;(f )Removal Positioned at the insulating layer of solder bath wire surface;(g)Solder is added in solder bath, and so that solder is fixed on welding by heating and puts down Face.
Magnetic coil lead and conducting terminal welding are integrated by the present invention by plumb joint, and can effectively improve solder joint can By property, melting even if solder joint is heated again, lead will not occur to detach with conducting terminal because of own tension, simultaneously as Solder is placed in solder bath spaced apart from each other, will not be lost in after the heated thawing of solder, after temperature reduces, be melted around Solder can solidify again, to ensure that the reliability of solder joint, prevented short circuit and open circuit phenomenon generation, in addition, solder Curing mode can be used high temperature furnace and be cured, and such as reflow soldering or oven, product can in high volume carry out heating simultaneously makes solder Admittedly being fixed on welding plane, production efficiency is efficient.

Specific implementation mode
Shown in Fig. 6, a kind of 4 welding method of magnetic coil includes the following steps:One insulating base 1 is provided, The insulating base 1 includes several side walls 11 and a bottom wall 12, and several side walls 11 and bottom wall 12 form a storage tank 13, absolutely Edge pedestal 1 is provided with several solder baths spaced apart from each other 14 in side wall 11, and solder bath 14 is spaced from each other by jube 16, further includes Several conducting terminals 2 of side wall 11 are fixed on, the conducting terminal 2 has the welding plane 21 for being exposed to solder bath 14;It provides The insulating base 1 is fixed on fixing groove 31 by the holder 3 with an at least fixing groove 31, and a fixation can be arranged in holder 3 Slot 31(Such as Fig. 4), or multiple fixing grooves 31 are set(Such as Fig. 5), with improving production efficiency;Magnetism with several leads 41 is provided Coil 4, the magnetic coil 4 are contained in storage tank 13;Lead 41 is placed in solder bath 14, lead 41 is made to be located at welding plane 21 tops, lead 41 can be fixed by holder 3, or be fixed on external auxiliary jig, further comprising the steps of:Pass through a plumb joint (It is not shown)Lead 41 and 21 welding of welding plane are integrated, the plumb joint uses high-frequency welder principle, plumb joint tool There is the tip less than solder bath 14 to heat up by moment when tip is contacted with lead 41, lead 41 is made to be fused to welding plane 21;Insulating layer of the removal positioned at 14 lead of solder bath, 41 surface(Lead 41 is enameled wire, and internal is metallic conductor, surface packet It has been covered with the coat of paint of insulated barriers effect, insulating layer has been constituted, the insulation can be removed by existing common laser or wicking mode Layer);Solder is added in solder bath 14, and so that solder is fixed on welding plane 21 by heating.
The trunking 15 for running through solder bath 14 from storage tank 13 is provided on side wall 11, the lead 41 penetrates trunking 15 It is placed in 21 top of welding plane.
The solder is solid tin ball.
Certainly, the solder can also be thick tin cream, technique effect having the same.
In this case, to make solder be fixed on welding plane 21, solder mode of heating can be heated by laser equipment.
So that solder is fixed on the mode of welding plane 21 as another kind, can be carried out by the way that product is directly placed into high temperature furnace Heating, the high temperature furnace are reflow soldering or oven.
Embodiment one, the insulating base 1 are provided in side wall 11 and cut line groove 112 for cut off excess lead 41, Tangent line can be carried out by blade or laser beam, after solder is added in solder bath 14, further include excision excess lead 41, will insulate Pedestal 1 is acted from 3 taking-up of holder, and due in advance taking out insulating base 1 from holder 3, then when being heated to solder, holder 3 is not It need to be heated together with solder, therefore, reduce the requirement to 3 heat resistance of holder.
Embodiment two, the insulating base 1 are additionally provided in side wall 11 for cutting off cutting line groove for excess lead 41 112, tangent line can be carried out by blade or laser beam, solder is heating and curing after in welding plane 21, further includes step:Excision is more Remaining lead 41 takes out insulating base 1 from holder 3, this embodiment and embodiment one difference lies in:Holder 3 need to be together with weldering Material heats together, relatively high to 3 heat resistant requirements of holder.
The holder 3 is in being provided with several support rims 32 in fixing groove 31, if 1 side wall 11 of the insulating base is provided with The dry assembling grove 111 coordinated with support rim 32.
The above, only better embodiment of the invention, but the present invention is not limited to above-described embodiments, as long as It reaches the technique effect of the present invention with any same or similar means, should all fall into protection scope of the present invention.
