Technical field
It is a kind of VCP pre-treatments circulating jet agitating device specifically the present invention relates to VCP pre-electroplating treatments.
Background technology
In general FPC manufacturing process, copper facing is one of its topmost operation, and existing FPC end products are to compact
Direction is developed, and conducting bore dia is less and less, and 30um-75um apertures product is more and more.Because hole increasingly comes intensive, aperture is got over
Come smaller.
In existing FPC flexible printed circuit boards manufacturing process, production plate through needed after heavy copper/black holes/shadow into VCP
Pre-electroplating treatment is processed again copper plating groove and is electroplated again to plate face and hole wall.In this pretreatment process, can go out
It is abnormal that existing VCP pre-treatments liquid medicine infiltration not enough causes plating appearance to jump plating/plating leakage etc..
The defect that general VCP pre-electroplating treatments are present at present：
1. liquid mixing is carried out using circulation pipe+pump-up device.The solution uniformity is poor, causes product topica water infiltration not
It is enough.
2. the easy mixing of air stirring is easily caused dissolved oxygen and increases, and liquid oxidation Decomposition increases.
3. pre-treatment rinsing bowl only has overflow without any circulation, and liquid medicine residual cleaning performance is not good.
Therefore, existing conventional VCP pretreating devices have much room for improvement and develop.
The content of the invention
It is an object of the invention to provide a kind of VCP pre-treatments circulating jet agitating device.
In order to overcome the above-mentioned defect present invention of the prior art to adopt the following technical scheme that：
A kind of VCP pretreating devices, including jet pump and the pipeline that is connected with jet pump, the multiple rows of array of pipeline are located at preceding place
In reason rinsing bowl or/and soaking compartment；It is characterized in that：
The pipeline is evenly provided with port and nozzle, and screw thread is provided with port, in the external screw thread on nozzle and port
Screw thread coordinates；The nozzle is provided with water inlet, guiding port, interior delivery port and out outlet, and water inlet connects with the screw thread in port
Connect, interior delivery port is located at water inlet, guiding port is located between interior delivery port and out outlet.
Further, the pipeline is corrosion resistant PP pipelines, and its a diameter of 35mm sets a port at interval of 8cm.
Further, a diameter of 1mm of the interior delivery port, the diameter 8mm of out outlet, the diameter 6mm of guiding port.
Further, the nozzle is just installed to arrangement, is reached big flow of the nozzle without air stirring and is exchanged.
Further, if the Pipe installing of jet pump connection dried layer array is in pre-treatment rinsing bowl or/and soaking compartment
It is interior.
Preferably, area of low pressure is formed around guiding port, high speed operation jet and the guiding port of interior delivery port are attracted
Low pressure liquid with 1:4 liquid-conveying amount enters out outlet mixing diffused spray out.
Preferably, a kind of method of VCP pre-treatments：
Step one：In the device rinsing bowl and soaking compartment in claim 1；
Step 2：Jet pump is opened, the liquid in rinsing bowl and soaking compartment forms the liquid of the Uniform Flow of circulation stirring；
Step 3：Workpiece is put into rinsing bowl and soaking compartment and is processed.
The VCP pretreating devices that the present invention is provided design simple science, it is to avoid air contact and liquid oxidation Decomposition, circulation
Stirring is better processing effect, improves the quality and qualification rate of product, creates benefit higher.

Specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment, herein with schematic implementation of the invention
Example and explanation are for explaining the present invention but not as a limitation of the invention.
As shown in Figure 1 to Figure 3, a kind of VCP pretreating devices, including jet pump 1 and the pipeline 2 being connected with jet pump 1, pipe
The multiple rows of array in road 2 is located in pre-treatment rinsing bowl or/and soaking compartment；Pipeline 2 is evenly provided with port 21 and nozzle 22, port 21
Screw thread is inside provided with, the external screw thread 221 on nozzle 22 coordinates with the screw thread in port 21；Nozzle 22 is provided with water inlet 23, guiding port
24th, the threaded connection in interior delivery port 25 and out outlet 26, water inlet 23 and port 21, interior delivery port 25 is located at water inlet 23
Place, guiding port 24 is located between interior delivery port 25 and out outlet 26.
Pipeline 2 is corrosion resistant PP pipelines 2, and its a diameter of 35mm sets a port 21 at interval of 8cm.
A diameter of 1mm of interior delivery port 25, the diameter 8mm of out outlet 26, the diameter 6mm of guiding port 24.
Nozzle 22 is just installed to arrangement, is reached big flow of the nozzle 22 without air stirring and is exchanged.
If the pipeline 22 that jet pump 1 connects dried layer array is installed in pre-treatment rinsing bowl or/and soaking compartment.
Area of low pressure is formed around guiding port 24, the high speed operation jet of interior delivery port 25 is attracted with guiding port 24
Low pressure liquid is with 1:4 liquid-conveying amount enters the mixing of out outlet 26 diffused spray out.
Further to embodiment principles illustrated：
Area of low pressure is formed around guiding port 24, liquid makes because areal pressure difference and liquid momentum attract liquid
High speed operation jet is common with the liquid being attracted with 1:4 liquid-conveying amount enters mixing diffuser jet flow out, realizes molten
The big flow stirring that liquid mixes without air, improves the solution uniformity, and then improve plate face infiltration cleaning performance.Solve to jump plating/leakage
Plating problem, while black holes/shadow/heavy copper is adapted to, VCP plating related process.
In sum, using increase in soaking compartment multiple rows of pipeline carry out to spray by the way of be circulated stirring, nozzle is just
Arrangement is installed, big flow of the nozzle without air stirring is reached and is exchanged, also increased simultaneously in pre-treatment water-cleaning overflow groove and use pipe
Road 22 (Eductor nozzles) is circulated stirring, it is ensured that cleaning performance.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
