Description
Technical field
The utility model is related to a kind of anodes, specifically, being related to a kind of group Heyang for different size whole plates to be electroplated
Pole.
Background technology
In electroplating industry, each system always has some typical components to implementing for electroplating technology to be essential.
Including the electroplating bath for containing electroplating solution, it is known that the material compatible with conventional Electroplating Solutions have polypropylene, polyethylene,
PVC, PVDF, stainless steel, titanium, lead or glass etc..Electroplating bath size depends on electroplating bath and accommodates component to be electroplated and complete electricity
The ability of ancillary equipment needed for plating.
Ancillary equipment can ensure that plating solution performance is kept uniform and stable in electroplating process, to ensure electroplating quality always such as
One.Heater and cooling device for keeping bath temperature, for ensuring air stirrer that homogeneous solution exchanges and molten
Alloy melt stirring device, the solution filtering device for removing hazardous particulate matter and the chemistry for keeping key chemical components concentration
Feeding system belongs to this row.
Another well-known key component of system is the anode used in electroplating process.Plating must be by sun
Pole could form the complete circuit that production solution is flowed through for electronics, to make the metal of reduction in deposition process appear in portion
On part, that is, so-called cathode.Electron stream follows effect electric field line and flows through electroplating solution, and electric field line is then by anode and cathode
Geometry or shape and anode and cathode present position determines relative to each other.
Quality of coating be heavily dependent on electric field line component or cathode surface distribution situation.Ideally,
Should try to form uniform current distribution on entire cathode or parts surface, to farthest improve quality of coating and
Uniformity.For there is the region of excessive electric field line, such as exterior angle and edge.High electron concentration may lead to the electricity in these regions
It is high to plate rate, to cause the coating in these regions thicker.In some extreme cases, it is possible that porous no adhesion
Coating.On the contrary, seldom existing position, coating then may be relatively thin for the electric field lines such as components interior region, in some extreme feelings
In condition, coating may not be formed nearly or completely.
In electroplating industry, especially printed circuit board electroplating industry, thickness of coating be distributed for product function and at
This has great influence.Thickness of coating distribution is influenced by Multiple factors, including the size of anode and the opposite printing of anode
The direction etc. of circuit board.Thickness of coating be unevenly distributed it is often unwelcome, this is because it can generate the performance of coated component
Adverse effect, when the thickness of coating deficiency in coated component low current density region, in order to make the coating in the region reach minimum
High current density region may have to be excessively electroplated in thickness requirement, and then improves the manufacturing cost of product.
When designing the electroplating device such as printed circuit board plating, usually follows plating regulation and be directed to specific dimensions
Component is designed.For example, when determining anode dimension, usually allow anode shorter than whole plate and about 2.5-10 centimetres narrow.This
Sample, which is done, helps to make electric current onboard, and more particularly along being uniformly distributed on the region at whole plate edge, thickness is plated to reduce whole plate
The variation of degree.
Once equipment purchasing is installed and put into production, rethink according to plating regulation more exchange device to meet other rulers
Very little whole plate production needs to become very difficult or even unrealistic, is finished because one side equipment has been assembled, in addition a side
The way of the other sizes anode suitable for different part dimensions is stopped work and installs from the perspective of cost and manufacture in face
And it is undesirable.
Utility model content
In order to overcome the defects of the prior art, the utility model provides a kind of group for different size whole plates to be electroplated
Heyang pole.Wherein, each anode is divided into multiple electric isolution anode segments, and each section can individually activate as needed, with effective root
" work " size for changing anode according to printed circuit board size avoids actually extracting and replacing anode or deposit sizes sun
Pole.The utility model can be according to the dimensionally-optimised anode dimension of printed circuit board, and then improves the distribution of workpiece thickness of coating.For
Realization the purpose of this utility model, the technical solution of the utility model are as follows：
The utility model provides a kind of combined anode for different size whole plates to be electroplated, and the combined anode includes sun
Pole A, anode B and positive C, wherein anode A are rectangular anode plate, and anode B and positive C are U-shaped anode plate, and anode A is put
It sets in anode B, anode B is placed in positive C, and anode A, anode B and positive C are all connected with switch 2 and are used at any time according to work
Make to need to switch on and off the electric current by above-mentioned anode.
In a preferred embodiment of the utility model, anode A and anode B interval 1-2cm, anode B and positive C interval
1-2cm。
In a preferred embodiment of the utility model, anode A, anode B and positive C are generally aligned in the same plane interior.
The utility model is intended that with a kind of comprising the anode for being not attached to section electrically isolated from one.Industry may be used in the anode
Common materials manufacture, but preferred inertia covering (such as yttrium oxide or other mixed-metal oxides or platinum) cladding titanium
Manufacture inertia or insoluble anode.
Each anode segment is connected with a rectifier, can be powered at any time according to need of work.If processing larger whole plate,
Then by being powered to multiple anode segments that are not attached to, annode area is maintained as possible close in the level of operating instruction requirement.Such as
Fruit processes smaller whole plate, then by the way that being not attached to anode segment power-off, annode area is maintained as possible close to operating instruction requirement
Level on.
The anode design of the utility model can be effectively reduced to be generated due to annode area and electroplating parts sizes mismatch
Electroplating thickness it is uneven in addition part cross plating and caused by quality problems, also because galvanization coating uniformity improvement and significantly
Electroplating cost is saved.In addition, because annode area can be carried out simple according to plated workpiece size and quickly be adjusted, effectively
It improves the production capacity of electroplating bath and greatly improves production efficiency.Simultaneously as annode area can be according to plated workpiece
Size adjusting, when producing the workpiece of reduced size, edge strip or masking are plated in need not be additional add, and have also effectively saved electricity
Plate cost.
