Abstract
The utility model discloses a characters piece film structure of circuit board, including characters film main part, be equipped with in the characters film main part with the circuit board on the continuous one or more characters piece of rule or non - regular graphic's position one -to -one, the characters piece is equipped with the even unanimous lower china ink portion of area and keeps off black portion, down china ink portion in proper order to arrange formation latticed at the interval with keeping off china ink. The utility model discloses film adoption to characters piece did not by a large scale change out the net into by not opening the net originally, the lower oil mass of control printing ink, the lower oil mass that makes characters piece department oozes and prints the circuit board from china ink down, the next door of lower china ink portion is then make printing ink can not ooze through keeping off china ink portion, since down china ink portion with keep off china ink portion each other at a distance from the setting, the printing back, under the flow naturally of printing ink, keep off the corresponding position of china ink portion on the circuit board and also printed printing ink, the oil mass reduces under final the messenger, cross the reinforcing of UV machine stabilizing effect in the normal condition, reduce the production that drops of whiting oil clot.
Description
Technical field
The utility model relates to a kind of aid made for pcb board, is more particularly a kind of character block film structure of circuit board.
Background technology
Serigraphy belongs to porous printing, and it is called as four large printing processes together with flat stamping, convex print, gravure.Porous printing comprises reputation and writes version, engraves hole flower version, spraying decoration and serigraphy etc.The principle of porous printing is: forme (the version base of paper film version or other editions being produced the eyelet by ink) is when printing, make the eyelet of ink passing hole version transfer on stock (paper, pottery etc.) by certain pressure, form image or word.It is the easiest porous printing that reputation writes version printing.In porous printing, most widely used is serigraphy.Serigraphy is stretched tight on screen frame by silk fabrics, synthetic fabrics or woven wire, adopts manual method of carving paint film or photochemistry plate-making to make screen printing forme.Modern screen printing technology is then utilize photosensitive material to make screen printing forme (make the silk screen hole of areas on screen printing forme be through hole, but not the silk screen hole of areas being plugged) by photomechanical method.By the extruding of scraper plate during printing, make ink be transferred on stock by the mesh of areas, form the picture and text the same with original copy.
In modern printed circuit board (PCB) (PCB) makes, also use screen printing technique.In the manufacturing process of PCB, often need to form one deck soldering-resistance layer on PCB, then print character on PCB, to identify the position of wire, various components and parts.Usually, as shown in Figure 1, have the character block 1 that some are continuous print large area bulk relative to common alpha or numerical character, character block 1 is in as triangle, rectangle, polygon etc., and because oil ratio word lines under character block are many, the UV energy required for ink solidification also wants high, normal condition crosses UV machine, the place of lower Chuck Steak is more difficult solidifies completely, and baking step is many, and due to UV solidification effect difference after character printing, easily produce character and solder mask adhesion bad and come off.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provides a kind of normal condition to cross UV machine solidification effect and strengthen, and reduces character block and to come off the character block film structure of circuit board produced.
The purpose of this utility model is achieved through the following technical solutions:
A kind of character block film structure of circuit board, comprise word film main body, described word film main body is provided with the position one or more character block one to one with continuous regular on circuit board or irregular figure, described character block is provided with lower black portion and the ink block portion of area uniformity, described lower black portion and ink block portion be intervally arranged successively formed latticed.
Concrete, described lower black portion, ink block portion have a rectangular shape, and the described foursquare length of side is 0.075mm.
The utility model has the following advantages and beneficial effect compared to existing technology:
The utility model adopts by not opening grid changed out grid into originally for the film of large-area character block, control the lower oil mass of ink, the lower oil mass at character block place is made to ooze out from lower black portion and be printed onto circuit board, the side in lower black portion then makes ink can not ooze by ink block portion, due to the spaced setting in lower black portion and ink block portion, after printing, under the natural flow of ink, ink has also been printed in the position that on circuit board, ink block portion is corresponding, lower oil mass is finally made to reduce, cross UV machine solidification effect in normal condition to strengthen, reduce large white oil block and to come off generation.
Accompanying drawing explanation
Fig. 1 is the structural representation of character block on the word film.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the enlarged drawing of character block in Fig. 2.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 2 and Figure 3, the present embodiment provides a kind of character block film structure of circuit board, comprise word film main body 2, described word film main body 2 is provided with the position one or more character block 1 one to one with continuous regular on circuit board or irregular figure, described character block 1 is provided with lower black portion 3 and the ink block portion 4 of area uniformity, described lower black portion 3 and ink block portion 4 be intervally arranged successively formed latticed.
In order to ensure that printing quality meets the requirements, described lower black portion 3, ink block portion 4 have a rectangular shape, and the described foursquare length of side is 0.075mm.By said structure, under the ink in character block region, oil mass is just suitable with normal alphabetic character oil mass, fully dry after crossing UV curing.
In the present embodiment, described ink block portion 4 is the region of a light-permeable on the film, lower black portion 3 is the shade of not light-permeable, word film main body 2 is when being specifically applied to half tone, first open half tone, and one deck emulsion is coated with on the grenadine of half tone, word film main body 2 is put on half tone, then sends in exposure machine and exposes.Inject half tone because shadow region blocks light, region half tone only having ink block portion cover can extinction, and due to extinction, change of properties occurs.The aqueous cleaning stage is entered after exposure.In this stage, the emulsion of change of properties occurs and retains due to water insoluble solution, other regions are then dissolved and the aqueous solution and disappearing.Printed text word ink is removed again with ready-made half tone, by the part (lower black portion) that the aqueous solution is washed off, grenadine is only had because there is no latex, then pcb board face can be seeped into during printing ink, by the part (ink block portion) after illumination, because solidification retains, ink can ooze, and plate face then prints not curing ink.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
