Description
Technical field
The present invention relates to PCB(printed wiring board, comprise flexible circuit board and hard wiring board) welding resisting layer and character, and printing process.
Technical background
At present, PCB first carries out welding resisting layer (claiming again solder mask, welding protective layer) printing, then carries out character (claiming again word, word marking, character marking) printing, and traditional printing process is mainly take silk-screen as main.Along with the rise of inkjet technology, welding resisting layer printing device and character printing device are there is.
According to existing technology and technique, the welding resisting layer on PCB two sides is to separate printing with character, can print different colors on two sides.But the welding resisting layer of the same face or character can only print a color, and welding resisting layer printing and character printing are to print as two procedures.Required long processing time, the color of printing is single.Adhesion between character layer and welding resisting layer is bad, and character easily comes off from welding resisting layer.
Summary of the invention
Content of the present invention is: during to PCB one side solder-mask printing layer, directly print the welding resisting layer of multiple color by the method for inkjet printing; Can print specific color in specific region, for distinguishing different regions; Can also character be shown with the color table that is different from background colour.
Method provided by the invention has following feature.
A method of printing polychrome welding resisting layer, is characterized in that: print the welding resisting layer that comprises at least two kinds of colors by the method for inkjet printing.The key that is different from prior art is: for the welding resisting layer of PCB one side, prior art feature is the monochromatic welding resisting layer of printing; Technical characterictic of the present invention is the welding resisting layer of printing two or more colors.
In order to reach the desired thickness of welding resisting layer, this method is characterised in that after improving: reach appointed thickness by once printing or repeatedly superposeing to print; The number of plies that zones of different stack is printed can be identical, also can be not identical.
For can be by functional areas or specific region on color differentiating PCB, after this method improvement, be characterised in that: in each functional areas or specific region, print the welding resisting layer of particular color separately.
In order to reach the object of print character, this method is characterised in that after improving: while printing welding resisting layer, use a kind of color or the multiple color that are different from background color to print character.The key that is different from prior art is: the prior art feature of character is the independent printed layers being printed on welding resisting layer; Technical characterictic of the present invention is that a color or several color of welding resisting layer self visually shows as character.
The process and method that prints character has multiple, and this method is characterised in that after improving.
When the region of multiple-layer stacked printing welding resisting layer needs printable character: every one deck welding resisting layer all prints character; Or only in the end which floor welding resisting layer prints character; Or only in the end one deck welding resisting layer just prints character; Or any one deck welding resisting layer does not print character, character is printed as extra one deck.
Individual layer is printed and is not needed welding resisting layer region that multiple-layer stacked prints while needing printable character: welding resisting layer and character are printed simultaneously; Or welding resisting layer does not print character, character is printed as extra one deck.
Although character can be used as extra one deck and prints, welding resisting layer of the present invention and character layer process on same work top.Prior art is on different operating table top, to process welding resisting layer and character layer, and this is the key that is different from the present invention and prior art.
Print the ink of welding resisting layer because of color difference, and other chemistry or physical characteristic difference.As: viscosity, granular size, curing UV characteristic wavelength etc.
For inkjet printing ink difference used, in print procedure, need diverse ways to be cured.Can first carry out precuring, then solidify completely; Also can directly solidify completely.Print for multiple-layer stacked, conventionally carry out precuring to every layer, after to be superimposed completing, solidify completely again.

A kind of polychrome welding resisting layer, is characterized in that: the welding resisting layer of PCB one side comprises at least two kinds of colors.The key feature of distinguishing existing welding resisting layer is: the welding resisting layer of existing PCB one side is monochromatic.
In order to reach the required thickness of welding resisting layer, described polychrome welding resisting layer is characterised in that after improving: described polychrome layer is formed by one deck or multiple-layer stacked; Because each region welding resisting layer all thickness requirement is not necessarily identical, the number of plies of zones of different stack can be identical, also can be not identical.
In order to distinguish functional areas and the region on PCB by color, described polychrome welding resisting layer is characterised in that after improving: described polychrome welding resisting layer in each functional areas or specific region have specific color.
For fear of print character again, described polychrome welding resisting layer is characterised in that after improving: the relative background color of one or more colors of welding resisting layer self is shown as character.Here it is to be understood that: character is a part for welding resisting layer, because color is different from background color, and show as the discernible character of vision.If character part comes off, welding resisting layer also just occurs damaged; And the character of prior art is to stick to above welding resisting layer, character comes off does not affect the complete of welding resisting layer; This is also the key that is different from the present invention and prior art.
Welding resisting layer and character have various ways performance, it is characterized in that.
The character in the welding resisting layer region that multiple-layer stacked forms: every one deck all comprises character; Or only have last which floor comprise character; Or only in the end one deck just comprises character; Or any one deck does not all have printable character, character is extra extra play.
Individual layer is printed the character in the welding resisting layer region forming: welding resisting layer comprises character; Or welding resisting layer does not comprise character, character is extra extra play.
Although character can be extra extra play, be considered the extension of normal welding resisting layer, be also a part for welding resisting layer.
Compared with prior art, the invention has the advantages that: can distinguish each functional areas or the specific region on PCB by color; Character, as a part for welding resisting layer, there will not be the phenomenon coming off because adhesion is poor, has also reduced text printout operation and required cost.
