First specific embodiment
See also Figure 1A to Fig. 1 E, be the cutaway view of an embodiment of alloy fled rheostat method for making of the present invention.
Shown in Figure 1A, prepare an alloy sheet material 1, can be for example the flat lamellar body or the strip material of alloy materials such as nickel, chromium, manganese, aluminium or copper, this alloy sheet material 1 comprises: a plurality of each intervals and run through the opening 10 of this alloy sheet material 1; And a plurality of resistance alloys unit 12 that are positioned at 10 of this adjacent apertures, respectively this resistance alloys unit 12 has an insulating coating district 121 and is positioned at the electrode tip 123 of these 121 both sides, insulating coating district.Usually, the opening 10 of aforementioned alloy sheet material 1 is formed by impact style.
Shown in Figure 1B, application in 121 surfaces, insulating coating district of this resistance alloys unit 12 by electricity and form insulating barrier 16.Particularly, the method for making of this covering insulating barrier 16 comprises: form one on this alloy sheet material 1 surface and expose the plating resistance layer 18 in the insulating coating district 121 of this resistance alloys unit 12; With this alloy sheet material 1 place one accommodate band cation or anion coating cell body (not shown) and switch on, the coating of following by band cation in the cell body or anion is attached to 121 surfaces, insulating coating district to form this insulating barrier 16; And remove this plating resistance layer 18, shown in Fig. 1 C.Since electricity application techniques the coating of band cation or anion is formed at treat attaching surface, therefore, do not have print process to have the shortcoming of directivity also do not have the uneven problem of spraying process rete.In addition,, can change the pattern of plating resistance layer 18, for example, also expose the part of two electrode tips 123 of resistance alloys unit 12, make coating be able to cover part electrode tip 123 according to different demands.That is to say that the formed insulating barrier 16 overlay film district 121 of can insulating certainly extends to partial electrode end 123.
Consult Fig. 1 C and Fig. 1 D again, along defiber 15 these alloy sheet materials 1 of cutting, to obtain separated resistance alloys unit 12.
At last, on the electrode tip 123 of this resistance alloys unit 12, form then material 19 of conduction, can obtain alloy fled rheostat of the present invention; Wherein, This conduction then material 19 is selected from the material that comprises nickel or tin, and this conduction follows material 19 and coat this electrode tip 123 surfaces fully like Fig. 1 E, also can only be formed on the single side; Connect for this alloy fled rheostat and to place on other electric device, for example on the circuit board.
In addition, the method for making of aforementioned alloy fled rheostat forms the conductive layer like copper in this electrode tip after also can being included in and covering this insulating barrier.
In addition, aforementioned in the formation of electrode tip copper conductive layer, also can, the resistance alloys unit form after separating with the barrel plating mode.
In being formed with the embodiment of conductive layer, this conductive layer is to follow between the material between this electrode tip and conduction.
Second specific embodiment
Shown in Fig. 2 A to Fig. 2 C; The sketch map that shows second embodiment of alloy fled rheostat method for making of the present invention, in the present embodiment, resistance alloys unit 12 arrays of this alloy sheet material 1 ' are arranged alternately; And also comprise connecting portion 14; For one connects the electrode tip 123 of adjacent two resistance alloys unit 12, in detail, this connecting portion 14 is connected in the rear electrode end 123 of a resistance alloys unit 12 and the preceding electrode tip 123 of another resistance alloys unit 12.In addition, in separating resistance alloys unit 12, as long as the resistance alloys unit 12 that this connecting portion 14 of cutting can obtain separating.
The present invention is by on the alloy sheet material, forming a plurality of each intervals and running through the opening of this alloy sheet material; And the alloy sheet material of this open side edges application techniques by electricity and is coated an annular insulating barrier; The insulating barrier of gained is formed by the coating of band plus or minus ion; The insulating barrier that therefore, can obtain having an even surface.It is electricity coating be scattered in the water that this electricity application mechanism, and coating will be deposited on the surface, insulating coating district during energising, and form even non-water-soluble insulating barrier.Electricity the advantage of application be can obtain to film uniformly by the adjustment of energising voltage; Add and be coated with water content of membrane and quantity of solvent is less; So can form and good be coated with face and can not produce bubble or cavity; And because the high penetration of liquid coating, adopt electricity application can promote the corrosion resistance of whole workpiece with coated to the general inaccessible position of spraying method.Moreover, electricity the afterwards contained quantity of solvent of coating and the water dilution of application extremely low, so be difficult for catching fire.Moreover, adopt electricity during the application processing work paint loss little, Dust Capacity is therefore rare, and the pollution level of environment is relatively also greatly reduced.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of claim of the present invention.
