Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, circuit board developer solution filter is described further.
As shown in Figure 1, the circuit board developer solution filter 10 of an embodiment, comprises medicine cylinder 100, screen pack 200 and cotton pad 300.
Medicine cylinder 100, for storing developer solution, has an openend 110.In the present embodiment, medicine cylinder 100 is in cuboid.Be appreciated that in other embodiments, medicine cylinder 100 also can be cylindrical, hexagon etc.
In the present embodiment, medicine cylinder 100 sidewall is provided with interface 120.Interface 120 for being connected with automatic powder adding Teat pipette, with by medicine cylinder 100 developer solution export.Be appreciated that in other embodiments, interface 120 also can omit, and when the liquid in medicine cylinder 100 reaches predetermined altitude, removes screen pack 200 and cotton pad 300, is exported by developer solution from openend 110.
Screen pack 200 covers openend 110.
Cotton pad 300 is positioned at the side of screen pack 200 away from medicine cylinder 100, and covers openend 110.
Traditional filter is exactly lay screen pack in the openend of medicine cylinder, the dry film residue of bulk can be stoped to enter medicine cylinder, but can not well stop tiny dry film residue and liquid medicine crystal to enter medicine cylinder, filter effect is limited, the situation of nozzle is blocked up in easy appearance, even cause flexible PCB to occur out the situation of short circuit, serious meeting causes flexible PCB to scrap.In foregoing circuit plate developer solution filter 10, by setting up cotton pad 300, the space due to cotton pad 300 is far smaller than the space of screen pack 200, thus can effectively prevent dry film residue, liquid medicine crystal etc. from entering medicine cylinder 10.Therefore, foregoing circuit plate developer solution filter 10 has good filter effect, effectively can avoid the situation occurring stifled nozzle, also can effectively avoid flexible PCB to occur out the situation of short circuit.
Further, in the present embodiment, screen pack 200 is flexibly connected with medicine cylinder 100, and the area of screen pack 200 is greater than the area of openend 110, and the edge of screen pack 200 extends towards the cylinder bottom of medicine cylinder 100 from openend 110.Thus become heavy when being positioned at the cotton pad 300 on screen pack 200 because absorbing developer solution, and then when screen pack 200 is exerted pressure, the screen pack 200 being positioned at openend 110 can form depression towards the cylinder bottom of medicine cylinder 100, (usually to concentrate on the middle part of cotton pad 300 because of the developer solution flowed out in the cylinder that develops with cotton pad 300 adaptation, relatively maximum to the impulsive force at the middle part of cotton pad 300, and cotton pad 300 becomes heavy because absorbing developer solution, and mainly concentrate on the middle part of cotton pad 300, thus cotton pad 300 is caused to form depression towards the cylinder bottom of medicine cylinder 100).Be appreciated that in other embodiments, the edge of screen pack 200 also can between the outer wall of openend 110 and inwall, and the edge of screen pack 200 is fixedly connected with medicine cylinder 100.
Further, as Fig. 2 and Fig. 3, in the present embodiment, the edge of cotton pad 300 flushes with the outer wall of openend 110, or the edge of cotton pad 300 is between the outer wall and inwall of openend 110.And the edge of cotton pad 300 is provided with bound edge 310.Bound edge 310 removably connects with the end face of openend 110.After foregoing circuit plate developer solution filter 10 uses a period of time, cotton pad 300 has a lot of dry film residue, liquid medicine crystal etc., after a period of time, need to change.Cotton pad 300 and medicine cylinder 100 removably connect, and are convenient to very much change cotton pad 300.
Further, in the present embodiment, circuit board developer solution filter 10 also comprises threaded post 400.Bound edge 310 is provided with through hole 312, and the position that the end face of openend 110 is corresponding with through hole is provided with internal thread hole 112.Threaded post 400 successively through through hole 312 and screen pack 200, and is fixed on internal thread hole 112.Cotton pad 300 is fixed on medicine cylinder 100 by threaded post 400, after can effectively avoiding cotton pad 300 to absorb developer solution, gravity concentrates on the middle part of cotton pad 300, cause cotton pad 300 towards medicine cylinder 100 cylinder bottom formed depression time, the edge of cotton pad 300 moves inward, and then cause cotton pad 300 can not cover openend 110 completely, and cause developer solution to be flowed directly on screen pack 200 without cotton pad 300, affect filter effect.
Further, in the present embodiment, the number of bound edge 310 is multiple, and multiple bound edge 310 is spaced apart in cotton pad 300, and each bound edge 310 is provided with a through hole 312.Concrete, cotton pad 300 is square, and the number of bound edge 310 is four, and four bound edges 310 are distributed in four corners of cotton pad 310 respectively.Be appreciated that in other embodiments, in the form of a ring, the inwall of bound edge caves in formation storage tank bound edge, and the edge of cotton pad is placed in storage tank, and bound edge is provided with multiple through hole be intervally arranged.
Further, in the present embodiment, cotton pad 300 is oil suction cotton pad, thus can better adsorb lipophilicity substance.The developer solution flowed out in development cylinder, the certain temperature had, some lipophilicity substances can be scattered in developer solution.After the temperature of the developer solution being positioned at medicine cylinder 100 reduces, these lipophilicity substances crystallization can form granule.Oil suction cotton pad effectively can avoid the generation of the problems referred to above.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
