Abstract
The utility model discloses a two-phase composite metal anode bar which belongs to the technical field of electroplating auxiliary equipment of printed circuit boards. The two-phase composite metal anode bar is technically characterized by comprising a bar body made of pure copper, wherein a protection cover which does not react with a plating solution and is made of a pure metal material is wrapped on the outer wall of the bar body along the length direction. The two-phase composite metal anode bar has the advantages of simple structure and long service life, and is capable of resisting the corrosion and the oxidization, and is used for electroplating printed circuit boards.
Description
Technical field
The utility model relates to a kind of anode used for electroplating bar, more particularly, relates in particular to a kind of two-phase composition metal anode rod.
Background technology
Can use anode rod in printed electronic circuit board industry electroplating process, the main purpose of anode rod is at the edge of coating bath, anode to be hung, thereby holding anode makes the distribution of electric current when electroplating the most even on the optimum position of reserving in advance.and in prior art, general PCB producer is all that pure copper tube or brass are as anode rod, horizontal edge at coating bath facilitates fixed anode, the anode rod of this routine is not only perishable, and easily crystallization of surface, increased contact resistance, the consume electric current, work-ing life is limited, the cost waste is larger, also be unfavorable for environmental protection, the more important thing is that this conventional anode rod placement location also can be subject to certain restrictions, for example: can not be too near near plating solution, otherwise crystallization, material after being corroded can pollute plating solution, make coating produce projection, burr, coarse grade has a strong impact on the problem of quality of coating.So this traditional anode rod needs the segment distance place of frame above plating solution.This segment distance makes anode, and some exposes plating solution, can not play a role, and the waste resource makes anode can not be fixed on the optimum position simultaneously, also can affect the problems such as distribution of current in coating bath and coating uniformity.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, can be anticorrosive, the two-phase composition metal anode rod of anti-oxidant, long service life.
The technical solution of the utility model is achieved in that a kind of two-phase composition metal anode rod; comprise the bar body of being made by fine copper, be enclosed with the protective sleeve of being made by the pure metal material that does not react with plating solution on wherein said bar body outer wall along its length.
In above-mentioned a kind of two-phase composition metal anode rod, described protective sleeve is the pure metallic titanium protective sleeve.
In above-mentioned a kind of two-phase composition metal anode rod, described protective sleeve is pure metal pick protective sleeve.
In above-mentioned a kind of two-phase composition metal anode rod, the internal diameter of described protective sleeve is identical with the external diameter size of bar body.
In above-mentioned a kind of two-phase composition metal anode rod,, described bar body is cylindrical, described bar body diameter is 25mm～35mm.
In above-mentioned a kind of two-phase composition metal anode rod, the jacket wall thickness of described protective sleeve is 3～10mm.
After the utility model adopts said structure, by the tight protective sleeve made by the pure metal material that does not react with plating solution of parcel on bar body outer side wall.Compared with prior art, have following beneficial effect:
(1) intensity and bending resistance are good, and the reliability of two-phase composition metal anode rod supporting anodes is higher;
(2) adopt the rolling production technique to make two kinds of pure metal combine closely, can not produce the good conductivity of delamination so tool
(3) corrosion-resistant, anti-oxidant, it is good anticorrosive that the protective sleeve material is that pure metallic titanium or pick have, and antioxidant property is good, long service life, and can put into plating solution, and segment anode can not exposed plating solution, avoid waste, can economical with materials.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in accompanying drawing, but do not consist of any restriction of the present utility model.
Fig. 1 is the structural representation of the utility model embodiment 1.
In figure: bar body 1, protective sleeve 2.
Embodiment
Embodiment 1
Consult shown in Figure 1, a kind of two-phase composition metal anode rod of the present utility model, two-phase is compound namely refers to the material that two kinds of different metals form, and does not react each other or generates new material.The utility model comprises the bar body 1 of being made by fine copper, and bar body 1 is cylindrical, and described bar body 1 diameter is 25mm～35mm.Simultaneously, the length of bar body 1 is unrestricted, can produce according to the length of the different model coating bath of production use.Be enclosed with the protective sleeve 2 of being made by the pure metal material that does not react with plating solution on described bar body 1 outer wall along its length, particularly, in the present embodiment, described protective sleeve 2 is the pure metallic titanium protective sleeve, is applicable to copper facing, nickel plating and gold plating solution.The internal diameter of protective sleeve 2 is identical with the external diameter size of bar body 1, adopts the rolling production technique to make two kinds of metals can be fully closely in succession compound.Further, the jacket wall thickness of described protective sleeve 2 is 3～10mm.So that having, protective sleeve protects preferably intensity, simultaneously longer service life.
A kind of two-phase composition metal anode rod of the present utility model, its structure is identical with embodiment 1, and difference is, and described protective sleeve 2 is pure metal pick protective sleeve, is applicable to Tin plating electrolyte.
Above-described embodiment is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other different size specification composition metal anode rod is so similar; and other any do not deviate from change, the modification done under spirit of the present utility model and principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.
