Abstract
The utility model is related to a kind of wiring board printing apparatus, including square frame and the grenadine that is arranged in square frame, and the grenadine upper surface is provided with below photoresists, the grenadine and has been sequentially overlapped carburization zone and water accepting layer.Compared with traditional first full print ink, the rear way for removing formulation region ink, by using web plate of the present utility model, can be realized when printing-ink is only needing the local printing-ink of ink, and do not needing the local not printing-ink of ink, not only simplify the difficulty of production and processing, improve operating efficiency, and saved ink, effectively controlled production cost.
Description
Technical field
The utility model is related to pcb board production field, and in particular to a kind of wiring board printing apparatus.
Background technology
In the production of PCB leaf fat ink prints, common screen printing method is to cover web plate in PCB plates upper surface, so
One layer of ink is coated on web plate afterwards.Because web plate is the equally distributed grenadine of mesh, the ink being coated on web plate can be complete
It is printed on monoblock PCB plates.But in actual production, due to usually needing to make the PCB plates of local printing-ink, that is, exist
Some regions are unable to coating printing ink on pcb board, are now accomplished by additionally making exposure film and are exposed development, it would be desirable to weld
PAD on ink rinse out.But consequently, it is possible to which completing this complete ink printing needs various production station, drag slow
The processing efficiency of mass production line, is unfavorable for the development of factory.
And with the miniaturization of electronic product complete machine, bring the minimizing of component, it is highly integrated so that PCB
Plate develops to small, thin, high density, multilayer, small-bore direction, and hole therein is no longer only for plug-in unit.Especially in some devices
Beneath via, plays the conducting effect with each layer.During to prevent that device from welding, solder is scurried out from these vias, occurs electricity
The short circuit phenomenon on road, it is necessary to when PCB plates are processed, use ink plugging.Resistance of the ink by the hollow gas of via, it is impossible to make
Ink is full in PCB plate vias so that ink can not injection via, the quality of influence product, formation defective products.
Utility model content
The utility model purpose is to provide a kind of wiring board printing apparatus, and it can be efficiently solved in the presence of background technology
The problem of.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of wiring board printing apparatus, including square frame and the grenadine that is arranged in square frame, the grenadine upper table
Face is provided with below photoresists, the grenadine and has been sequentially overlapped carburization zone and water accepting layer.
Further, the lateral edges two ends of square frame one are respectively equipped with the first fixed frame and the second fixed frame, described
First fixed frame and the second fixed frame are fixed by hinge with square frame, and first fixed frame and the second fixed frame are used to press from both sides
Hold the film.
Further, the photoresists include the first photoresists and the second photoresists, first photoresists and the second sense
Optical cement completely covers grenadine upper surface, and first photoresists and the second photoresists are pasted onto grenadine upper surface.
Further, the film is provided with black light-blocking region, white transparent area, the black light-blocking region and first photosensitive
Glue location and shape all same, the white transparent area and the second photoresists location and shape all same.
Further, the water accepting layer is sponge.
Grenadine is fixed in square frame by glue, and grenadine is stretched to maximum, it is ensured that grenadine is in straight extend
State, grenadine upper surface coat one layer of photoresists, by film left and right ends be clamped in respectively the first fixed frame and second fix
Frame, the first fixed frame of upset and the second fixed frame, make the film be covered in above photoresists, and the film is provided with black light-blocking region and in vain
Corresponding photoresists are that corresponding photoresists are below the first photoresists, white transparent area below color transparent area, black light-blocking region
Second photoresists.Above-mentioned web plate is inserted in exposure machine and exposed, the photoresists then cleaned by cleaning agent on web plate.Due to black
Light-blocking region blocks the light sent in exposure machine so that zone position that light can not be reached by black light-blocking region and black is in the light
The first corresponding photoresists, therefore optical polymerization reaction does not occur for the first photoresists, chemical property does not change, can be clear
Agent is cleaned during washing to remove；On the other hand, because white transparent area allows the injection of light that is sent in exposure machine, make
Second photoresists corresponding with white printing opacity zone position, therefore the second photoresists can be reached by white transparent area by obtaining light
Generation optical polymerization reacts so that the chemical property of the second photoresists changes, because cleaning agent can not remove generation chemistry
Photoresists after change of properties, the second photoresists are remained on grenadine.The film is taken out, and will be covered with the second photoresists
Web plate be placed on PCB plates, PCB plates and web plate are then put into silk-screen in screen printer in the lump, in the upper table of PCB plates
Face carries out ink for screen printing.Due to the stop of the second photoresists, the region corresponding with the second photoresists will not be printed on PCB plates
Paint ink.Directly unnecessary ink in via is drawn using water accepting layer and easily draw excess but ink covering is not comprehensive, lead to
Cross carburization zone to draw ink unnecessary in via and strengthen the air guide ability of via, then the oil in carburization zone is drawn by water accepting layer
Ink, prevents clogged with ink and influences the air guide effect of carburization zone.
It is of the present utility model to have technical effect that：
It is new by using this practicality compared with traditional first full print ink, the rear way for removing formulation region ink
The web plate of type, can be realized when printing-ink is only needing the local printing-ink of ink, and is not needing ink
Local not printing-ink, not only simplifies the difficulty of production and processing, improves operating efficiency, and saved ink, effectively controlled life
Produce cost.
