Description
Technical field
The utility model belongs to the production technical field more particularly to a kind of E-glass fibre of electronic-grade glass fiber cloth
Cloth woven fabric treatment fluid circulation and stress device is tieed up, which is suitable for printed circuit alkali-free electronic-grade glass fiber cloth used
It manufactures, electronic-grade glass fiber cloth printed circuit board substrate suitable for electronics industry.
Background technique
Scientific and technological progress is at full speed, and intellectual product on the market is increasingly frivolous, and function is stronger and stronger, more and more function meetings
It being integrated on a module, the pitch of holes on circuit board is also smaller and smaller, so be greatly to test to circuit board overall performance,
Also require the quality-improving of raw material to higher simultaneously, enhancing of the electronic grade glass cloth as printed circuit board, insulating body, product
The promotion of matter performance is also that necessarily, current high-end consumption electronic product institute has fallen to 20um using glass-fiber-fabric thickness, this type
High-end glass-fiber-fabric is best in quality for Japan's production, the high-end product of institute, domestic manufacturers output, in the visible flaw of fabric appearance naked eyes
On defect, with external product without too many differences, but in terms of sightless physical property, it still can not be promoted to external peer-level,
Overall performance is insufficient, so us is more required to make great efforts to improve production details.
Glass fabric belongs to inorganic matter, and simple glass can not be effectively combined with resin, so glass-fiber-fabric manufactures
Manufacturer all can infiltrate one layer of couplant on glass cloth surface after glass cloth weaving is completed, this couplant is there are two chemical bonds, and one
End is combined closely with glass-fiber-fabric, and one end can make glass-fiber-fabric and resin form stable and closeization with the chemical bonds of resin
It learns and combines, rather than simple physics covers, the quality of couplant determines the height of glass cloth overall performance in this treatment process
It is low, but the level for the treatment of process and the processing in terms of details also can cause very big shadow to yield of the finished product in the client of downstream
It rings.
Couplant is that a variety of chemical substances are deployed with solvent, and long agitation is needed to be allowed to completely after the completion of allotment
It is even, it then reuses pump and is delivered to production scene use, be also required to constantly carry out circulation holding uniformly in production process, if because
Couplant uneven and cause uneven in conjunction with glass cloth, on downstream after resin, segment glass cloth surface does not have
Enough chemical bonds and resin-bonded, easily generation plate bursting etc. are bad, and glass-fiber-fabric surface has segment glass fiber when production
It falls in treatment trough, long-term accumulation risky can adhere to cloth cover again and cause fabric appearance abnormal, it is also desirable to couplant
Couplant in coating groove carries out continuous circulating filtration.
Circulation used in production process is single channel circulation at present, because production linear speed is fast, internal circulating load is big, single channel
Machine speed circulation will cause circulation liquid outlet position and generate a large amount of bubbles, on the one hand bubble can hinder the effective of couplant and glass cloth
In conjunction with, on the one hand will form foam, foam can polymerize in conjunction with air, attachment of polymers cloth cover formed pollution, under causing
The regional location will form dumping when swimming coated with resins, and dumping problem is the exception that CCL factory strictly manages, once occur to pick
It removes.
Summary of the invention
The purpose of this utility model is that overcoming the deficiencies of the prior art and provide a kind of electronic-grade glass fiber cloth woven fabric
With treatment fluid circulation and stress device, circulation used in existing production process is single channel circulation, and single port goes out liquid, single port into
Liquid is only able to achieve the uniform for the treatment of fluid, but a large amount of foams generated simultaneously cause risk to the physical property stabilization of product, this is practical new
Type increases couplant circulator on existing treatment trough, and installs Multichannel uniform additional in couplant circulator liquid outlet position
Liquid outlet is depressurized, to reduce the generation of circulation drain position bubble, improves glass cloth quality, CCL is reduced and scraps.
In order to achieve the above objectives, the utility model provides following technical solution:
A kind of electronic-grade glass fiber cloth woven fabric treatment fluid circulation and stress device, including couplant treatment trough, couplant
Circulation line, circulating pump & filter device, evenly dispersed liquid discharge device；
The bottom of couplant treatment trough offers the outlet of couplant treatment trough, is provided with uniformly at the top of couplant treatment trough
Disperse liquid discharge device；
One end of couplant circulation line is couplant circulation line entrance, and the other end is that couplant circulation line goes out
Mouthful；Couplant circulation line entrance and couplant treatment trough outlet, the outlet of couplant circulation line and evenly dispersed liquid out
Device connection；Circulating pump & filter device is provided on couplant circulation line；
Circulating pump & filter device includes circulating pump and filter device, and circulating pump provides power for entire circulation and stress device,
The filoplume clast that filter device is used to wash down after couplant treatment trough through glass cloth filters out；
Evenly dispersed liquid discharge device includes liquid entrance and multiple equally distributed liquid outlet channels upper in the horizontal direction, each
Liquid outlet channel is all made of into small big out；The entrance of all liquid outlet channels is connected to liquid entrance out.
Further, the quantity of liquid outlet channel can be adjusted according to the groove body size and flow of couplant treatment trough, no
It is fixed.
Evenly dispersed liquid discharge device subtracts press juice using multichannel, as shown, evenly dispersed liquid discharge device goes out simultaneously
Liquid channel be designed as into it is small go out it is big, as shown, reducing fluid pressure to increase liquid level product out, can effectively reduce single port and go out
The flow velocity of liquid reduces bubble and generates, and reduces the obstruction that bubble effectively combines couplant with glass cloth.
The utility model can recycle treatment fluid currently in use, i.e., pass through treatment fluid from processing trench bottom extraction
Then filtering re-injects treatment trough from above, glass-fiber-fabric can be from treatment trough continuously across being infiltrated when which works
Treatment fluid.
Compared with prior art, the utility model has the beneficial effects that: multi-pass, which is recycled, says liquid, and liquid outlet hole
Diameter be designed as into it is small go out it is big, increase liquid level product out, reduce fluid pressure, can effectively reduce the flow velocity that single port goes out liquid, reduce bubble
It generates, reduces the obstruction that bubble effectively combines couplant with glass cloth.
