Abstract
The invention discloses a general base plate for a printed circuit board screen printing plug hole, and the general base plate comprises a rectangular panel, wherein a circle of closed wall is formed by upward and integral extension of four peripheries of the panel, multiple support walls are formed by upward and integral extension of the upper surface of the panel, the support walls are positioned in the circle of closed wall, the upper ends of the support walls are flush with the upper end of the circle of closed wall, the multiple support walls are parallel to one another and have an included angle of 45 degrees with the circle of closed wall respectively, gaps exist between the two ends of the support walls and the circle of enclosed wall, and a flow passage for air and ink to circulate is formed among the circle of closed wall, the panel and the support walls. The general base plate is applicable to different part numbers, can be reused, has low possibility of polluting a printing cabinet and a plug hole panel, and is convenient to operate, good in air permeability and easy to clean.
Description
Technical field
The invention belongs to the PCB(printed circuit board (PCB)) the used backing plate of consent operation in the manufacturing process, especially a kind of structure-improved of backing plate.
Background technology
The consent operating type that present industry generally adopts is the wire mark consent, because of its required capital equipment---and the printing board is that the dealer generally has, and outfit---web plate, scraper, backing plate and contraposition pin etc. also are permanent stores.Wire mark consent work flow is roughly as follows: the position, hole of the Kong Weiyu jack panel on backing plate and the web plate is identical, backing plate is fixed on the printing board, backing plate, jack panel and web plate three from bottom to top stack gradually the location, three's Kong Weixiang contraposition, scraper is printed on the web plate, printing ink is pressed in the hole of jack panel by squeegee pressure, the hole of backing plate can make the air in the jack panel hole discharge smoothly in the consent process, thereby printing ink can be filled in the hole of jack panel smoothly, and the unnecessary printing ink of jack panel enters in the hole of backing plate.There is following shortcoming in this consent operating type: one, increase cost: because of the size of different item numbers different with consent, backing plate can not share, need repeat to change, backing plate needs to make separately according to item number, after single item number was produced, backing plate must be scrapped, not reproducible utilization, increase boring cost and backing plate cost of material, and expended man-hour; Two, influence production efficiency: backing plate, jack panel and web plate three's Kong Weixu contraposition is in the same place, complex operation, and change item number at every turn, must repeat this operation, image production efficiency; Three, influence quality: the backing plate gas permeability is not fine, and bubble is arranged during consent easily, causes consent not full, because the hole of backing plate is up/down perforation, the printing ink that enters in the backing plate hole pollutes printing board and jack panel easily.
Summary of the invention
In order to address the above problem, the invention provides the general backing plate of a kind of printed circuit board (PCB) wire mark consent, the general backing plate of printed circuit board (PCB) wire mark consent of the present invention is applicable to different item numbers, and is reusable, be difficult for to pollute printing board and jack panel, and easy and simple to handle, good permeability, cleaning are convenient.
The present invention for the technical scheme that solves its technical problem and adopt is:
The general backing plate of a kind of printed circuit board (PCB) wire mark consent, the flat board that comprises a rectangle, the surrounding of described flat board make progress one be extended with one the circle closed enclosure wall, the described dull and stereotyped upper surface one that makes progress is extended with some knee walls, described knee wall is positioned at described enclosure wall, the upper end of described knee wall flushes with the upper end of described enclosure wall, described some knee walls are parallel to each other and are 45 with described enclosure wall, there is distance between the two ends of described knee wall and the enclosure wall, constitutes the runner for air and printing ink circulation between described enclosure wall, flat board and the knee wall three.
The invention has the beneficial effects as follows: the general backing plate of printed circuit board (PCB) wire mark consent of the present invention be make progress in the surrounding of flat board one be extended with one the circle closed enclosure wall and some knee walls, knee wall is positioned at enclosure wall, the upper end of knee wall flushes with the upper end of enclosure wall, some knee walls are parallel to each other and are 45 with enclosure wall, there is distance between the two ends of knee wall and the enclosure wall, enclosure wall, constitute the runner for air and printing ink circulation between flat board and the knee wall three, runner can play the effect of breathing freely and building up unnecessary printing ink, owing to be not the backing plate that adopts conventional borehole, do not need the hole contraposition with jack panel, so the present invention is applicable to all item numbers, during consent, backing plate of the present invention is fixed in the printing board, only needs web plate and jack panel contraposition, jack panel only need be fixed on the backing plate of the present invention and get final product, also need not to change backing plate of the present invention when changing item number, simplify operation, saved man-hour, improved production efficiency; Backing plate of the present invention can reuse, and has saved cost of material; Because runner circulates in whole backing plate of the present invention surface, ventilation space is big, good permeability, be difficult for during the jack panel consent producing bubble, product quality is good, and printing ink accumulates in the runner, can not flow to and pollute the printing board on the printing board, can not pollute jack panel yet.

Embodiment
Embodiment: the general backing plate of a kind of printed circuit board (PCB) wire mark consent, the flat board 1 that comprises a rectangle, the surrounding of described flat board make progress one be extended with one the circle closed enclosure wall 2, the described dull and stereotyped upper surface one that makes progress is extended with some knee walls 3, described knee wall 3 is positioned at described enclosure wall 1, the upper end of described knee wall 3 flushes with the upper end of described enclosure wall 2, described some knee walls 3 are parallel to each other and are 45 with described enclosure wall 2, there is distance between the two ends of described knee wall 3 and the enclosure wall 2, described enclosure wall 2, constitute the runner for air and printing ink circulation between flat board 1 and knee wall 3 threes.
