Fig. 2 is the structural representation of the terminal that the bonder terminal wire rod of employing the utility model embodiment is corresponding.
Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined with each other, and are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1, the utility model embodiment provides a kind of bonder terminal wire rod, comprise metal wire main body 10, insulating barrier 20 shaping successively and conductive coating 30, described insulating barrier 20 and conductive coating 30 respectively take shape in the outer surface of metal wire main body 10 along metal wire main body 10 length direction.Particularly, described conductive coating 30 is Gold plated Layer or plating palladium nickel dam.Thus metal wire main body 10 surface arranges insulating barrier 20 and conductive coating 30 spaced reciprocally, conductive coating 30 position is accurate, and manufacturing speed is fast, and effectively reduces the area coverage of conductive coating 30, greatly reduces costs, economizes on resources.
As a kind of execution mode, the length of each insulating barrier 20 is greater than the length of conductive coating 30.Particularly, such as: the length of insulating barrier 20 is 20mm to 25mm, the length of conductive coating 30 unit is 15 mm to 19mm.Conductive coating 30 position like this is accurate, and manufacturing speed is fast, and effectively reduces the area coverage of conductive coating 30, thus reduces manufacturing cost.Thus as required only in the exposed parcel plating of bonder terminal wire rod, and it does not plate gold or palladium nickel without the need to plating greatly yet, effectively reduces the area coverage of conductive coating 30, greatly reduces costs, economize on resources.Preferably, the material of the described plating also metal such as gold, silver, tin, nickel.
The circular in cross-section of described metal wire main body 10, its diameter is 0.3mm to 0.47mm.In other embodiments, the cross section of metal wire main body 10 also can be square.
Described metal wire main body 10 is preferably copper cash or copper covered steel circle line, adopts copper cash or the copper covered steel thread bonder terminal wire rod elasticity of circle and resistance to wear better.
The bonder terminal wire rod of the utility model embodiment is made by following electro-plating method, and described method comprises following step:
Pre-treatment step: degreasing, pickling and clean are carried out, to make its surface cleaning to the metal wire main body 10 of bonder terminal wire rod; Thus what pre-treatment step ensure that metal wire main body 10 cleans as subsequent treatment is laid a solid foundation;
Insulating barrier 20 forming step: the compartment of terrain spraying along its length of metal wire main body 10 surface or printing insulant, form evenly spaced insulating barrier 20;
Conductive coating 30 forming step: carry out continuous vertical to electrogilding or the process of palladium nickel, forms conductive coating 30 in non-insulated layer 20 region; And
Insulating barrier 20 removal step: adopt acid solution to be removed by described insulating barrier 20.Preferably, the formula of described acid solution is: phosphoric acid 500-600m1/L, glacial acetic acid 200-300mi/L, nitric acid 100-300m1/L, and corresponding removal temperature is room temperature, and the time of removing is 50s to 120s.Preferably, phosphoric acid 600m1/L, glacial acetic acid 300mi/L, nitric acid 100m1/L.In other execution modes, the mixed solution of red fuming nitric acid (RFNA) or chromic anhybride and hydrochloric acid is adopted to remove.Thus the removal of insulating barrier 20 avoids the terminal insulating barrier 20 of described bonder terminal wire rod making as occurring during conductive region that the situation of loose contact occurs.
As a kind of execution mode, between insulating barrier 20 forming step and conductive coating 30 forming step, also comprise hydrophobicity plating resist formable layer step: make hydrophobicity plating resist layer at insulating barrier 20 surface spraying or printing by hydrophobic material.Thus, at insulating barrier 20 surface forming hydrophobicity plating resist layer, reach good plating resist effect, ensure that the effect of plating on the one hand, on the other hand, avoid the waste of plated metal.Preferably, described hydrophobic material is a kind of hydrophobic resin, and this hydrophobic resin is selected from Merlon, dimethyl silicone polymer adipic acid diamide, polypropylene, and one of them of the combination of described material; Or described hydrophobic material is a kind of wax material, and this wax material comprises 50-95wt% wax and 10-40wt% inorganic oxide, and this inorganic oxide is selected from silicon dioxide, titanium dioxide, magnesium oxide, zirconia, and one of them of the combination of described material.Preferably, this wax material comprises 70wt% wax and 30wt% inorganic oxide.
Also comprise post-processing step after described insulating barrier 20 removal step, described post-processing step comprises cleaning, dries; Wherein, described cleaning is by deionized water rinsing or cleaned by ultrasonic vibration, and to remove the pollutant on surface, described oven dry carries out in an oven, temperature 750 DEG C, time 30min.Thus through cleaning, the bonder terminal wire rod of oven dry, surface cleaning is pollution-free, reliable in quality.
See also Fig. 2, the utility model embodiment bonder terminal wire rod can be used for manufacturing terminal, and corresponding terminal manufacturing method comprises:
Wire rod procedure of processing: adopt the electro-plating method of bonder terminal wire rod as above to make bonder terminal wire rod;
Cutting step: the terminal described bonder terminal wire rod being cut into Len req, each terminal comprises at least one conductive coating 30, and described conductive coating 30 is positioned at the end of terminal; And
