Abstract
The utility model discloses an improved tin welding wire, which comprises a welding core and a medicine coating coated outside the welding core, wherein the welding core is in a hollow structure, and a welding-supporting and fire-resistance insulation layer is coated outside the medicine coating. The utility model has the advantages that a cavity of the welding core can realize the welding resistance effect, the insulation layer outside the medicine coating can realize the welding-supporting and fire-resistance effect, and can prevent the occurrence of conditions such as insufficient welding, short circuit and the like. At the same time, the utility model has the advantage that welded welding points are full, round and lustrous.
Description
Technical field
The utility model relates to a kind of welding wire, particularly a kind of soldering silk.
Background technology
At present, often need to use scaling powder when using the soldering wire bond to connect, scaling powder can dissolve the oxide on surface on the one hand, and when weld heating, surround metallic surface, make it isolated with air, place metal oxidation when heating, can reduce the surface tension of fusion scolding tin, help the moistening of scolding tin, but too much use scaling powder, the impulse ratio that the result is subjected to when making welded plate carry welding more greatly, easily bubbles even causes situations such as drawing point, short circuit, rosin joint, corrodes components and parts or makes circuit board insulating properties variation.
Summary of the invention
The purpose of this utility model is to overcome above defective, and a kind of modified soldering silk simple in structure, easy to use is provided.
For achieving the above object, technical solutions of the utility model are as follows:
A kind of soldering silk comprises core wire and is wrapped in the outer coating of core wire that described core wire is a hollow-core construction, and coating scribbles the fluxing and fire-retarding insulating barrier outward.
Preferably, described fluxing and fire-retarding insulating barrier by the solderability resin, help weldering monomer, fire retardant and diluent to be polymerized; The cross-sectional diameter of described core wire internal cavity is 0.05mm-0.5mm.
The beneficial effects of the utility model are: the cavity of core wire can play the welding resistance effect, and the outer insulating barrier of coating can fluxing and fire-retarding prevents the generation of situations such as rosin joint, short circuit, and the solder joint that welds out of the utility model is full, mellow and full, glossy simultaneously.
Description of drawings
Accompanying drawing 1 is the utility model cross-sectional structure schematic diagram.
Among the figure: 1, core wire; 2, coating; 3, insulating barrier.
The specific embodiment:
For the utility model be should be readily appreciated that, further set forth the utility model below in conjunction with accompanying drawing.
In conjunction with the accompanying drawings 1, modified soldering silk of the present utility model comprises core wire 1 and is wrapped in the outer coating 2 of core wire 1, and core wire 1 is a hollow-core construction, and the cross-sectional diameter of core wire 1 internal cavity is 0.05mm-0.5mm.The coating 2 outer fluxing and fire-retarding insulating barriers 3 that scribble.Fluxing and fire-retarding insulating barrier 3 by the solderability resin, help weldering monomer, fire retardant and diluent to be polymerized.According to the welding needs, add scaling powder in some welding wire simultaneously, scaling powder can dissolve the oxide of metal surface, place to go, and surrounds metallic surface when weld heating, makes it isolated with air, prevents metal oxidation when heating; Can reduce the surface tension of fusion scolding tin, help the moistening of scolding tin.Some welding wire needs solder resist, and it is little to add the thermal shock that the welding wire of solder resist can protect panel that it is subjected to when welding, is difficult for bubbling, and also plays simultaneously and prevents bridge joint, draws point, situations such as short circuit, rosin joint.In the practical application, seldom there are both gather use,
Contain scaling powder in the utility model fluxing and fire-retarding insulating barrier, the hollow structure of core wire 1 has the welding resistance effect simultaneously, can determine the size of core wire 1 cavity diameter as required, thereby be applied to different components and parts welding aspects.The outer insulating barrier 3 of coating 2 can fluxing and fire-retarding prevents the generation of situations such as rosin joint, short circuit, and the solder joint that welds out is full, mellow and full, glossy.
Description in the foregoing description and the specification has just illustrated principle of the present utility model, and under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope.
