Description

Method for printing conductive metal circuit diagram on circuit substrate by lithography and printed product thereof

The present invention relates to a method for printing a conductive metal circuit pattern on a circuit substrate by using lithography and a printed product thereof, and more particularly, an advanced printing device and an innovative printing process, which are in the same line The operation method is to quickly print the conductive metal circuit diagram and related printing purposes required for the circuit substrate, and to improve the manufacturing efficiency and the overall manufacturing cost.

The so-called "printed circuit board" is the basic unit of any electronic device, which has a metal circuit diagram that can conduct electronic circuits, and then can apply various electronic parts and micros at the position or mark of the reserved circuit on it. The installation and connection of the processor or other electronic component accessories is the basic core of an electronic device; however, the inventors of the present invention will only refer to the initial process for fabricating a metal circuit diagram on the circuit substrate material. Ming, I would like to ask for inspection.

In today's most widely used screen printing process, it first attaches a layer of conductive metal to an insulating circuit substrate material, and then prints a layer on the conductive metal layer by screen printing. The anti-corrosion protection material of the circuit pattern is required, and the excess metal layer except the circuit pattern is removed by etching, photo-sensing technology or laser engraving, and then the anti-corrosion protection material is removed, thereby obtaining a metal only The printed circuit board of the circuit diagram is "semi-finished product".

The reason why these printed circuit boards which have been fabricated into metal circuit diagrams are referred to as semi-finished products, is that they must be printed on the end faces of other required marks, symbols or characters. Important printing steps to facilitate the smooth follow-up of related operations. Therefore, no matter how complicated the subsequent related operations of the finished printed circuit board, the original adhesive layer, the screen printing anti-corrosion protection material, etching, cleaning, printing, re-cleaning (removing excess ink), etc. Process steps, I believe that anyone can easily understand and understand the cumbersome, time-consuming and economic and environmental benefits of the process, so it is necessary to be eager to be improved.

Therefore, in view of the above facts, the inventors have actively invested in R&D and innovation based on their practical experience in the printing business for many years, and the invention has been published early; therefore, it is mainly printed in a single lithographic process. The expected conductive metal circuit diagram and printed markings, symbols, texts, and even the overall printing process of partitioning and coloring on the conductive metal circuit diagram, thereby greatly improving manufacturing efficiency and saving printing man-hours and costs, is the main Target person.

Yes, it is printed by a multi-color automatic printing machine and a plurality of printing stencils, wherein the first printing ink holder of the multi-color automatic printing machine is filled with adhesive glue (hereinafter They will all be referred to as viscose ink holders, and the second printing ink holder will be converted into a cold bronzing equipment and set with a roller-shaped conductive metal foil film material (hereinafter referred to as bronzing ink seat), and then each printing Ink holders are loaded with printing inks of various colors according to printing requirements (hereinafter referred to as color ink holders respectively), and corresponding printing templates are arranged at the stencil holders of the viscous ink holders and the ink holders. And each of the printing stencils has been separately patterned for the circuit, mark, symbol, text, etc. to be printed, therefore, when the circuit substrate material is fed according to the automatic conveying route of the multicolor automatic printing machine, It is possible to quickly complete the complete conductive metal circuit diagram and related printing and coloring processes.

In order to further understand the technical means and features of the present invention, it is described in detail with a number of schematic diagrams: as shown in the first figure, a schematic diagram of a multicolor automatic printing machine 10 modified by an inventor, first The track is an adhesive ink holder 11 filled with adhesive adhesive, the second of which is a hot stamping ink holder 12, and is provided with a roll-shaped conductive metal foil film material 20, and then each color ink holder 13 and 14 And 15, respectively, are loaded with printing inks of various colors according to printing requirements, and further, correspondingly disposed at the stencil holders 111, 131, 141, 151 of the ink stick 11 and the color ink holders 13, 14, 15 The circuit printing stencil 30 and the color printing stencils 32, 34, 36, and each of the circuit printing stencil 30 and the color printing stencil 32 have been respectively spliced with the circuit, mark, symbol, text, etc. to be printed. There are circuit engraving 31 and pattern engraving 33, 35, 37, therefore, when the circuit substrate material 40 is multicolor automatic printing machine 10 Once the automatic conveyor route is delivered, it is possible to quickly complete the complete conductive metal circuit diagram and related printing and coloring processes.

Accordingly, please cooperate with one of the preferred printing process examples shown in the second figure, the circuit printing template example shown in the third figure, and the color printing template examples shown in the fourth, fifth and sixth figures. For example, to describe its printing process: first, when the circuit substrate material 40 enters the adhesive ink holder 11 of the multi-color automatic printing machine 10, it will be coated according to the circuit engraving 31 on the corresponding circuit printing stencil 30. The adhesive layer 41, which is the same as the circuit pattern 31, is re-entered into the gilding ink holder 12, and the adhesive layer 41 will adhere the conductive metal on the conductive metal foil film material 20 by its adhesive force and thus After forming the conductive metal circuit pattern 42, and then entering the subsequent color ink holders 13, 14, 15, the colored printing plates 32, 34, 36 can be patterned according to the corresponding patterns 33, 35, 37 and formed into general colors. Layer 43, thereby quickly printing out the various types of marks that are expected to be desired (indicated in blue in the figure), symbols, text (shown in red in the figure), and color.

The reason why the local or specific area or specific lines are applied to the conductive metal circuit pattern 42 for coloring or color separation (in the figure is golden yellow) is mainly to make the product be used in the back end. When the back-end process (such as drilling, welding, cutting, packaging, etc.), the back-end user can use the clear display of the color as the discriminating target of the processing position, in addition to the improvement of the efficiency of the accelerated operation, A great utility for preventing erroneous processing.

The circuit board material 40 described above may be an insulating board for various types of hard and soft printed circuits which are currently widely used, such as an electric wood board, a fiberglass board, or a plastic board.

Furthermore, after the ink fountain 15 is finished at the last end, a plurality of preliminary ink holders 16, 17 will be reserved for use in more printing needs.

Of course, in order to increase the thickness of the metal coating of the conductive metal circuit of Figure 42, to ensure its The conductivity value can meet the necessary electrical conductivity requirements, and it must be repeated for the same printing surface over the glue and bronzing step; similarly, the circuit substrate material 40 can also be applied to the double-sided printing process, but the same is the same The simple transfer method, so the inventor will not repeat them.

Therefore, the present invention utilizes the multi-color automatic printing machine 10 and the appropriate addition and modification, in addition to fully utilizing the existing printing equipment to enhance the industrial utilization efficiency, and can greatly reduce the production, printing time and cost of the printed circuit board. .
