Abstract
The utility model discloses a printed circuit board screen printing hole plugging backing plate. The printed circuit board screen printing hole plugging backing plate comprises a rectangular flat plate; a ring of sealed surrounding wall extends out from the periphery of the flat plate; the upper surface of the flat plate is provided with a spiral flow channel wall integrally extending upwards; the flow channel wall is arranged inside the surrounding wall; the upper end of the flow channel wall is leveled with the upper end of the surrounding wall; and flow channels through which air and ink can pass are formed among the surrounding wall, the flat plate and the flow channel wall. When hole plugging is performed, the backing plate of the utility model is fixed on a printing machine stage, and a user only needs to align to a mesh board with a hole plugging plate, and the hole plugging plate only needs to be fixed on the backing plate of the utility model. The printed circuit board screen printing hole plugging backing plate of the utility model can be applicable to different materials, and can be repeatedly used, avoid pollution to the printing machine stage and the hole plugging plate; and the printed circuit board screen printing hole plugging 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 base plate of plug hole, and printed circuit board (PCB) wire mark base plate of plug hole of the present utility model is applicable to different item numbers, and is 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:
A kind of printed circuit board (PCB) wire mark base plate of plug hole, 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 the runner wall that is spiral, described runner wall is positioned at described enclosure wall, the upper end of described runner wall flushes with the upper end of described enclosure wall, consists of the runner for air and printing ink circulation between described enclosure wall, flat board and the runner wall three.
The beneficial effects of the utility model are: printed circuit board (PCB) wire mark base plate of plug hole of the present utility model comprises the flat board of a rectangle, the dull and stereotyped surrounding one that makes progress is extended with the enclosure wall of a circle closed and is the runner wall of spiral, the runner wall is positioned at enclosure wall, the upper end of runner wall flushes with the upper end of enclosure wall, enclosure wall, consist of the runner for air and printing ink circulation between flat board and the runner wall three, 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, and also need not to change backing plate of the present utility model when changing item number, has 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.

Embodiment
Embodiment: a kind of printed circuit board (PCB) wire mark base plate of plug hole, it is characterized in that: 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 the runner wall 3 that is spiral, described runner wall 3 is positioned at described enclosure wall 2, the upper end of described runner wall 3 flushes with the upper end of described enclosure wall 2, consists of the runner for air and printing ink circulation between described enclosure wall 2, flat board 1 and runner wall 3 threes.During consent, backing plate of the present utility model is fixed in printing machine platform, only needs 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.
