Abstract
The utility model discloses a printed circuit board screen printing hole plugging general-purpose backing plate. A circle of sealed surrounding wall extends upwards integrally from the periphery of a flat plate; a plurality of first flow guiding walls and a plurality of second flow guiding walls extend upwards integrally from the upper surface of the flat plate; the upper ends of the first flow guiding walls and the upper end of the second flow guiding wall are leveled with the upper end of the surrounding wall; the surrounding wall is provided with two opposite side walls which are a first side wall and a second side wall respectively; the first flow guiding walls and the second flow guiding walls are arranged alternatively and are both perpendicular to the first side wall and the second side wall; one end of each first flow guiding wall is integrally connected with the first side wall, and the other end of each first flow guiding wall is separated from the second side wall by a distance; one end of each second flow guiding wall is separated from the first side wall by a distance, and the other end of each second flow guiding wall is integrally connected with the second side wall; and channels through which air and ink can flow are formed among the surrounding wall, the flat plate, the flow guiding walls and the second flow guiding walls. The printed circuit board screen printing hole plugging general-purpose backing plate of the utility model is suitable for different materials and can be repeatedly used, is not easy to pollute a printing machine stage and a hole plugging plate; and the printed circuit board screen printing hole plugging general-purpose backing plate is advantageous in simple and convenient operation, excellent air permeability and convenience in cleaning.
Description
Technical field
The utility model 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 printing machine platform 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 machine platform, 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, affect 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, affect quality: the backing plate gas permeability is not fine, and bubble is easily arranged during consent, causes consent not full, because the hole of backing plate is up/down perforation, the printing ink that enters in the backing plate hole easily pollutes printing machine platform and jack panel.
The utility model content
In order to address the above problem, the utility model provides a kind of printed circuit board (PCB) wire mark consent the general backing plate of using, printed circuit board (PCB) wire mark consent of the present utility model is general to be applicable to different item numbers with backing plate, reusable, be difficult for to pollute printing machine platform and jack panel, and easy and simple to handle, good permeability, easy to clean.
The utility model for the technical scheme that solves its technical problem and adopt is:
The general backing plate of using 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 the first training walls and some the second training walls, described the first training wall and the second training wall all are positioned at described enclosure wall, and the upper end of the upper end of described the first training wall and the second training wall all flushes with the upper end of described enclosure wall, described enclosure wall has relative two side and is respectively the first side wall and the second sidewall, described the first training wall is interlaced with described the second training wall and all vertical with the second sidewall with described the first side wall, one end of described the first training wall is connected with described the first side wall one and there are distance in the other end and described the second sidewall, one end of described the second training wall exists distance and the other end to be connected described enclosure wall with described the second sidewall one with described the first side wall, dull and stereotyped, consist of the runner for air and printing ink circulation between the first training wall and the second training wall.
The beneficial effects of the utility model are: printed circuit board (PCB) wire mark consent of the present utility model general with backing plate be make progress in the surrounding of flat board one be extended with one the circle closed enclosure wall, and the dull and stereotyped upper surface one that makes progress is extended with some the first training walls and some the second training walls, the first training wall is interlaced with the second training wall and all the first side wall with enclosure wall is vertical with the second sidewall, one end of the first training wall is connected with the first side wall one and there are distance in the other end and the second sidewall, one end of the second training wall exists distance and the other end to be connected with the second sidewall one with the first side wall, enclosure wall, dull and stereotyped, consist of the runner for air and printing ink circulation between the first training wall and the second training wall, runner can play the effect of breathing freely and building up unnecessary printing ink, owing to not being the backing plate that adopts conventional borehole, do not need the hole contraposition with jack panel, so the utility model is applicable to all item numbers, during consent, backing plate of the present utility model is fixed in printing machine platform, only need web plate and jack panel contraposition, jack panel only need be fixed on the backing plate of the present utility model and get final product, also need not to change backing plate of the present utility model when changing item number, simplified operation, save man-hour, improved production efficiency; Backing plate of the present utility model can reuse, and has saved cost of material; Because runner circulates in whole backing plate of the present utility model surface, ventilation space is large, 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 printing machine platform on the printing machine platform, can not pollute jack panel yet.
