Description
Technical field
This utility model relate to a kind of improve electroplating evenness accompany plating edge strip, belong to technical field of plating equipment.
Background technology
Plating utilizes electrolysis principle to plate the process of other metal or alloy of a thin layer on some metal surface exactly, is
Utilize electrolysis to make the technique of surface attachment layer of metal film of metal or other material thus play and prevent metal oxygen
Change (such as corrosion), improve the effects such as wearability, electric conductivity, reflective, corrosion resistance (copper sulfate etc.) and having improved aesthetic appearance.Much
The outer layer of coin is also for plating.
Coating is single metal or alloy mostly, such as titanium palladium, zinc, cadmium, gold or pyrite, bronze etc.；Also there is diffusion layer, as
Nickel-carborundum, nickel-fluorographite etc.；Also has laminating layer, such as the copper-nickel-layers of chrome on steel, the silver-indium on steel
Layer etc..Plating matrix material in addition to cast iron, steel and the rustless steel of iron-based, also nonferrous metal, or ABS plastics, poly-third
Alkene, polysulfones and bakelite, but before plastic electroplating, it is necessary to through special activation and sensitized treatment.
SMD LED base plate for packaging process for treating surface requires the highest, and concrete surface to meet in product encapsulation beats gold thread
The pulling force of (Wire Bonding) and thrust requirements.The best surface treatment mode meeting dozen gold thread is exactly electric thick gold
(Au >=0.2um) or thick silver (Ag >=2.5um).The good surface treatment mode done of going together both at home and abroad at present is two-sided mostly
Electric thick gold or the thick silver of electricity, or nickel plating.
In electroplating process, in electroplating bath, the electric current density in each region can be because minus plate is different with the distance of positive plate or places
Processing workpiece how much the most different with position and change, electric current density difference can cause electroplating uneven.
The electroplating evenness of existing electroplating device is poor, and the result of its electroplating evenness shows, the thick overproof region of copper is main
Being distributed in and fly bar two ends, this is the main cause causing overall uniformity on the low side；If electroplating evenness is poor, it will affect circuit
The quality problem such as etching, finished product aperture, folder film, also can increase copper facing, stannum cost.
Utility model content
In order to improve electroplating evenness, this utility model provides one and accompanies plating edge strip, accompanies plating edge strip to be suspended on plating sun
Extremely go up, thus regulate the distance of galvanic anode and the workpiece to be plated of negative electrode, improve electroplating evenness.
This utility model is achieved through the following technical solutions above-mentioned purpose.
A kind of improve electroplating evenness accompany plating edge strip, including main edge strip and secondary bar, the upper end of described main edge strip is provided with
Hook, hook is provided with the first fixed knob, and the upper end of described secondary bar is provided with slip cap, and slip cap is enclosed within main edge strip also
Can move along main edge strip, described slip cap is equipped with the second fixed knob.
More preferably improvement project is, described hook is provided with rebate, and rebate is installed the first fixed knob, described roundabout
Portion is also connected with shell fragment, and shell fragment bends inside rebate, and the end of thread of the first fixed knob is against on shell fragment.
Further preferably, connected by one section of kink between main edge strip and hook.
Further preferably, the bottom of described secondary bar is provided with welding gasket.
Technique effect of the present utility model: regulation secondary bar changes the length accompanying plating edge strip with the relative position of main edge strip
Degree, uses this to accompany plating edge strip can regulate the electric current density in each region during plating, improves electroplating evenness.And this utility model
Plating edge strip of accompanying employ elastic piece structure, it is easy for installation with galvanic anode, and contact is well.
Accompanying drawing explanation
Fig. 1 is the front view accompanying plating edge strip.
Fig. 2 is the side view accompanying plating edge strip.
In figure: the most main edge strip, 2. slip cap, 3. hook, 4. welding gasket, 5. secondary bar, 6. rebate, 7. shell fragment, 8.
First fixed knob, 9. the second fixed knob, 10. kink.
Detailed description of the invention
In order to make it easy to understand, below in conjunction with the accompanying drawings this utility model is elaborated.
As depicted in figs. 1 and 2, described in the utility model accompany plating edge strip include main edge strip 1 and secondary bar 5, described main edge strip
The upper end of 1 is provided with hook 3, and hook 3 is provided with the first fixed knob 8, and the upper end of described secondary bar 5 is provided with slip cap 2, slides
Set 2 is enclosed within main edge strip 1 and can move along main edge strip 1, and described slip cap 2 is equipped with the second fixed knob 9, regulates secondary bar 5 He
The relative position of main edge strip 1 changes the length accompanying plating edge strip, accompanies the length of plating edge strip to determine according to the position of electroplating parts,
After regulating the position of secondary bar 5, fix the second fixed knob 9, then accompanying plating edge strip to hang on galvanic anode, tighten first
Fixed knob 8 is fixing accompanies plating edge strip.
As it is shown in figure 1, described hook 3 is provided with rebate 6, rebate 6 is installed the first fixed knob 8, described rebate
Being also connected with shell fragment 7, shell fragment 7 bends inside rebate 6, and the end of thread of the first fixed knob 8 is against on shell fragment 7, accompanies plating edge strip
When hanging on galvanic anode, shell fragment 7 is in close contact with galvanic anode, so accompanies plating edge strip contact effect more preferable, and electric conductivity is more steady
Fixed.
More preferably embodiment, is connected by one section of kink 10 between main edge strip 1 and hook 3, so makes to accompany plating limit
When bar hangs on galvanic anode, main edge strip 1 can align galvanic anode, advantageously ensures that electroplating effect.
Further, the bottom of described secondary bar 5 is provided with welding gasket 4, in order to extending accompanies the length of plating edge strip,
Or the convenient miscellaneous part with electroplating bath is fixed and is connected.
More particularly, described slip cap 2 is a loop members.
Do not use before accompanying plating edge strip, copper thickness 30um, edges of boards 1 ~ 2cm copper thickness 45um in the plate of copper facing plate, increase this practicality new
Type with accompany plating edge strip after, copper thickness 30um in the plate of LED-baseplate, edges of boards about 30um, the plating reaching to improve copper facing plate is equal
Even property.
Of the present utility model accompany plating edge strip can stretch, various sizes of copper facing plate can be used to accompany plating.
The above is only preferred implementation of the present utility model, it should be pointed out that: for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve
Also protection domain of the present utility model is should be regarded as with retouching.
