Abstract
The invention discloses a loudspeaker voice coil wire welding soldering flux and a preparation method thereof, and aims to solve the problems that a rosin water soldering flux for welding the voice coil wire has low soldering performance, extremely low welding productivity and dark and lusterless welding spots and that phenomena of loose welded voice coil wire, insufficient welding and cold solder easily occur after welding so as to cause a soundless loudspeaker or intermittent sound of the loudspeaker. The soldering flux comprises soldering fluid consisting of the following components: 3.8 to 4.8 weight percent of ammonium chloride, 0.07 to 0.12 weight percent of anhydrous sodium carbonate, 38 to 46 weight percent of glycerol and 50 to 58 weight percent of absolute ethyl alcohol; and the soldering flux also comprises rosin water which accounts for 70 to 80 percent of the total weight of the soldering flux. The soldering flux has good soldering performance, high welding productivity and saturated and bright welding spots, so that the voice coil wire is welded firmly. Therefore, the stable acoustical property of a loudspeaker is guaranteed.
Description
Technical field
The present invention relates to a kind of scaling powder, particularly a kind of loudspeaker voice coil line welding is with scaling powder and preparation method thereof.
Background technology
Voice coil loudspeaker voice coil is the core component of loudspeaker, and the quality of voice coil loudspeaker voice coil assembling has considerable influence to the acoustical behavior of loudspeaker.Voice coil loudspeaker voice coil comprises sound ring frame and is wound in the continuous voice coil line on the sound ring frame, needs the voice coil line welding fixing in the voice coil loudspeaker voice coil assembling process.Scaling powder is as loudspeaker welding auxiliary material commonly used; Be widely used in the loudspeaker welding field; During the voice coil line welding, as scaling powder, this scaling powder helps the weldering poor performance generally to adopt rosin (being the mixture of rosin and absolute ethyl alcohol); Welding sequence welding production capacity is extremely low; Welding back solder joint is gloomy, matt, and this scaling powder uses and causes very easily after welding on the voice coil line that the voice coil line welding is insecure, rosin joint, dry joint phenomenon, and then causes the noiseless or voice coil line loose contact of loudspeaker to cause the loudspeaker pronunciation phenomenon that cuts in and out.
Notification number is CN100493817C, and the day for announcing is the Chinese invention patent on June 3rd, 2009, has announced a kind of no-clean scaling powder and preparation method thereof; This scaling powder mainly is the improvement of making in order to reach the purpose of exempting to clean, and when voice coil line is welded, because solder joint is very little; Scaling powder postwelding residual quantity seldom; Do not need to clean, therefore this no-clean scaling powder welds voice coil line and does not have a specific aim, can't solve the problem that original voice coil line welding exists with scaling powder.
Summary of the invention
The objective of the invention is to solve the rosin scaling powder that the voice coil line welding uses and help the weldering poor performance, welding sequence welding production capacity is extremely low, and welding back solder joint is gloomy, matt; Cause very easily after the welding that voice coil line welding is insecure, rosin joint, dry joint phenomenon; And then cause the problem that loudspeaker is noiseless or the loudspeaker pronunciation cuts in and out, and provide a kind of loudspeaker voice coil line welding to use scaling powder, it helps the weldering performance good; The welding sequence production capacity is higher; Welding back solder joint is full, bright, makes the voice coil line firm welding, thereby the acoustical behavior that guarantees loudspeaker is stable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of loudspeaker voice coil line welding is used scaling powder, this scaling powder to comprise and is helped welding fluid, and the said welding fluid that helps is grouped into by following one-tenth: ammonium chloride 3.8
Wt% ~ 4.8
Wt%, natrium carbonicum calcinatum 0.07
Wt% ~ 0.12
Wt%, glycerine 38
Wt% ~ 46
Wt%, absolute ethyl alcohol 50
Wt% ~ 58
Wt%.There are many defectives in original rosin scaling powder after the welding, as the welding production capacity low, solder joint is gloomy, matt; Cause very easily that voice coil line welding is insecure, rosin joint, dry joint phenomenon, in order to overcome these defectives, the inventor has made technological improvement; Developed the above-mentioned welding fluid that helps, this helps the welding fluid can be directly as the welding of flux application in voice coil line, and it helps the weldering performance good; The welding sequence production capacity is higher; Welding back solder joint is full, bright, makes the voice coil line firm welding, thereby the acoustical behavior that guarantees loudspeaker is stable; Ammonium chloride, natrium carbonicum calcinatum play the effect of activating agent, and it is active to provide enough helping to weld, and welding effect is good; Glycerine plays the effect of film forming agent; Make and carry activating agent even film forming on solder joint after the solvent evaporates of scaling powder, obtain to go up the tin ability preferably, prevent that soldering from splashing; Tin is even in the assurance, and absolute ethyl alcohol then is the effect of playing solvent.
As preferably, this scaling powder also comprises rosin, and rosin accounts for 70% ~ 80% of scaling powder gross weight, and surplus is for helping welding fluid.Scaling powder of the present invention can only use help welding fluid, in order to be helped the weldering effect better, has also added rosin outside the welding fluid helping, and has formed and has helped weldering better effects if ground scaling powder, has further promoted the weldering performance that helps of the present invention.
As preferably, described rosin is grouped into by following one-tenth: absolute ethyl alcohol 50
Wt% ~ 60
Wt%, rosin 50
Wt% ~ 40
Wt%.Absolute ethyl alcohol is a solvent, and what rosin adopted is common rosin, non-modified rosin.
As preferably, the content that helps ammonium chloride in the welding fluid is 4.2
Wt% ~ 4.4
Wt%, Carbon Dioxide sodium content are 0.09
Wt% ~ 0.1
Wt%, glycerine content are 40
Wt% ~ 44
Wt%, absolute ethyl alcohol content are 52
Wt% ~ 56
Wt%.Amount to helping each composition of welding fluid is optimized, and helps the weldering effect with raising.
The welding of loudspeaker voice coil line is with the preparation method of scaling powder, and described preparation method may further comprise the steps:
1. the preparation of rosin: it is 200 orders ~ 300 purpose particles that rosin is processed into size, successively absolute ethyl alcohol and rosin particle is poured in the container by weight proportion, evenly stirs, and is dissolved in the absolute ethyl alcohol fully until the rosin particle;
2. help the preparation of welding fluid: successively glycerine, absolute ethyl alcohol, natrium carbonicum calcinatum, ammonium chloride are poured in the container by weight proportion, evenly stirred, natrium carbonicum calcinatum, ammonium chloride are dissolved fully;
3. rosin with help mixing of welding fluid: with the rosin for preparing with help welding fluid to pour into by weight proportion in the container, promptly rosin 70
Wt% ~ 80
Wt% helps welding fluid 30
Wt% ~ 20
Wt%, stirring gets final product;
Rosin need be processed into graininess, is beneficial to rosin and is dissolved in the absolute ethyl alcohol better, quickly, and choose reasonable rosin and the proportioning that helps welding fluid are to obtain to help better the weldering performance.
As preferably, step 1. in, after the rosin particle is poured in the absolute ethyl alcohol, every at a distance from stirring in 8 ~ 12 minutes once, be dissolved in the absolute ethyl alcohol fully until the rosin particle.After the rosin particle is poured in the absolute ethyl alcohol, be difficult for dissolving at once, need to stir again behind the immersion certain hour, could let the rosin particle be dissolved in the absolute ethyl alcohol fully like this.
The present invention has the following advantages:
1, cost of material is low, and the scaling powder of production is economical and practical;
2, help the weldering performance good, the welding sequence production capacity is higher, and welding back solder joint is full, bright, makes the voice coil line firm welding, thereby the acoustical behavior that guarantees loudspeaker is stable.
