Abstract
The utility model belongs to the technical field of assistant tools in the manufacturing process of a printed circuit board and discloses a novel solder-proof green oil film for a printed circuit board. The solder-proof green oil film comprises a graphic area and film sides on the outer side of the graphic area, wherein the film sides cover the contour on the edge of the printed circuit board, and a first opaque area with a width of 8-12 mm and a second opaque area with a width of 2.5-3.5 mm are plotted towards the outer side and the inner side of the film sides respectively by taking the contour on the edge of the printed circuit board as the reference line. The solder-proof green oil film is adopted in the working procedure of printing the solder-proof coating on the printed circuit board, and since green oil holes are formed on the film sides, the film sides are light-proof, copper is exposed out on the board edge of the printed circuit board without residual oil after aligning, exposure and developing, the oil ink on the board edge of the printed circuit board is prevented from being stuck onto the screen bottom during the subsequent text screen printing, and clear and complete printed words are ensured.
Description
Technical field
The utility model relates to the aid in a kind of printed wiring board manufacturing process, especially a kind of welding resistance green oil film that carries out exposing operation behind the printed wiring board electrostatic spraying welding resistance printing ink that is applicable to.
Background technology
Printed wiring board (Printed Circuit Board, PCB) in the process, through the finished product printed wiring board behind figure transfer, etching, the striping, before the assembling components and parts, except that pad and welding portion, remainder (comprising figure lead and substrate) all is coated with one deck soldering-resistance layer.This layer protection seal material can prevent from the bridging phenomenon takes place between lead when wave-soldering is carried out in the printed board that assembles, and can improve welding quality effectively, the rate of reducing the number of rejects and seconds.Simultaneously can save scolder again, alleviate the weight of printed board, reduce cost.On printed wiring board during electrostatic spraying welding resistance printing ink, the printed board edges of boards also can be sprayed printing ink, at present exposure film limit is a Transparent color, and the printing ink of edges of boards is cured behind contraposition, exposure imaging, and edges of boards printing ink can adhere to net bottom and causes the defective of oil down of character during follow-up character silk printing.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of and has been applicable to that printed wiring board plate electrostatic spraying welding resistance printing ink carries out can making edges of boards reveal the welding resistance green oil film of copper after contraposition, exposure, the development.
The utility model adopts following technical scheme: a kind of novel wiring board welding resistance green oil film, the film limit that comprises the graph area and the outside thereof, film limit covers wiring board edge contour, and described film limit is that the outside sidelight of datum line is painted with first opacity that width is 8～12mm, inside sidelight is painted with second opacity that width is 2.5～3.5mm with described wiring board edge contour.
As further improvement, the described first opacity width is 10mm, and the described second opacity width is 3mm.
As further improvement, described first opacity, second opacity are black.
The beneficial effects of the utility model are: adopt this welding resistance green oil film in the operation of wiring board printing welding resistance coating, because being added with green oil on film limit windows, make that film limit is light tight, after contraposition, exposure, development, can make the wiring board edges of boards reveal not Residual oil of copper, edges of boards do not have the ink adhesion net bottom when follow-up character silk printing, have guaranteed that lettering is clear, complete.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model wiring board welding resistance green oil film.
Embodiment
Elaborate below in conjunction with accompanying drawing.
Referring to Fig. 1, the wiring board welding resistance green oil film comprises the graph area 1 and the outside thereof film limit 2 all around, and film peripheral size is greater than printed wiring board, and film limit 2 can cover wiring board edge contour 21; Being added with green oil on film limit 2 windows, use to such an extent that film limit 2 is light tight, position of windowing and size are to be that datum line is windowed laterally with wiring board edge contour 21, be that to be painted with width be 8～12mm, first opacity 22 to light, and with wiring board edge contour 21 is that datum line is windowed to the inside, and promptly light is painted with second opacity 23 that width is 2.5～3.5mm.The best 10mm of being of first opacity, 22 width of windowing laterally, the best 3mm of being of second opacity, 23 width of windowing to the inside.Best first opacity 22 and second opacity 23 all light plot black.
This welding resistance green oil film is applicable to the exposure behind the electrostatic spraying welding resistance printing ink, because being added with green oil on film limit windows, make that film limit is light tight, after contraposition, exposure, development, can make the wiring board edges of boards reveal not Residual oil of copper, edges of boards do not have the ink adhesion net bottom when follow-up character silk printing, have guaranteed that lettering is clear, complete.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
