Compared with the prior art, the lead-free gold spraying material has the advantages of dramatically improving rate of fine variety of aluminium film capacitor.
Description
Technical field:
The present invention relates to a kind of welding material.
Background technology:
The aluminium film capacitor generally is to be made of fuse, the lead-in wire that is fixed on the fuse two ends, the protective layer that fuse is wrapped up; fuse is to be formed by the aluminium winding film; lead-in wire between lead-in wire and fuse end face, also is coated with no-lead gold spraying material, so that can stably link together with fuse.Wherein, no-lead gold spraying material is a kind of important material in the stable electric capacity of the quality of production, is subjected to the restriction of the environment for use of electric capacity, requires the acceptance rate of the electric capacity of manufacturing will reach very high level.Existing no-lead gold spraying material mainly is made of Sn, Zn, Cu, Sb, the aluminium film capacitor that the no-lead gold spraying material of employing prior art is made, and its acceptance rate is the highest also can only to reach 95%, and it is just extremely difficult further to promote acceptance rate.Because in electronic circuit, the rate of utilization of electric capacity is very high, even the acceptance rate of the electric capacity of being produced reaches 95%, but, still not enough for electronic circuit, because a plurality of 95% lump together, the acceptance rate of electronic circuit will sharply descend.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of leadless metal spraying material for capacitor that can significantly promote aluminium film capacitor acceptance rate.
The present invention realizes like this, mainly constitute by Sn, Zn, Cu, Sb, Ni, Al, lanthanum cerium mischmetal, wherein the weight content ratio of Sn is 82%-48%, the weight content ratio of Cu is 0.065%-0.050%, the weight content ratio of Sb is 1.2%-0.7%, and the weight content ratio of Ni is 0.13%-0.04%, and the weight content ratio of Al is 0.025%-0.013%, the weight content ratio of lanthanum cerium mischmetal is 0.08%-0.03%, other be Zn.The those skilled in the art of same domain know, if contain Al, will seriously influence the quality of product in Sn, Zn, Cu, Sb system.Breakthrough employing Ni, the lanthanum cerium mischmetal of the present invention cooperates with Al, add in Sn, Zn, Cu, the Sb system, not only do not influence the quality of product, promote the performance of product on the contrary significantly, the acceptance rate of the electric capacity that has adopted the technology of the present invention product can be reached more than 98%.
In order to satisfy the high quality requirement of small dimension aluminium film capacitor, the weight content ratio of Sn is 68-72% or 58-62% preferably.
Compared with the prior art the present invention has the advantage that can significantly promote aluminium film capacitor acceptance rate.
Embodiment:
Now in conjunction with the embodiments the present invention is described in further detail:
The present invention is mainly being made of Sn, Zn, Cu, Sb, Ni, Al, lanthanum cerium mischmetal of realizing like this.Following table is the various components contents of different embodiment and made aluminium film capacitor acceptance rate.
From the above embodiments as can be seen, the aluminium film capacitor that adopts leadless metal spraying material for capacitor of the present invention to produce, its acceptance rate can reach more than 98%, significantly the highest 95% taller than prior art.
