Problems solved by technology
Although this method has the advantages of fast manufacturing process time, no waste water pollution and low cost compared with the aforementioned etching method, the distance between the holes it produces is too large, that is, there are too few holes in a limited area, that is to say, the holes are distinguished. The rate is not high, resulting in too little contact area between the printer and the flexible circuit board, which reduces the accuracy of the contact between the two
Another serious problem is that the use of the impact method is likely to cause the substrate between the holes to break, which greatly reduces the yield of the finished product, and thus relatively increases the cost required for manufacturing

Embodiment Construction
[0019] The present invention specially designs an identifiable flexible circuit board, which is arranged on the ink cartridge (Cartridge), and the flexible circuit board can also form at least one identification area in the manufacturing method. For example, the present invention adds at least one colorant ( Colorant) to form the color of the identification area for the operator of the production line to identify. Among them, the present invention can also form identification marks such as company trademark (Brand Name), product material number (SerialNumber) and material tape specification on the flexible circuit board, which saves the production process and cost of additional reprinting, and makes it convenient for operators Identify product categories.
[0020] The structure of the identifiable flexible circuit board of the present invention is described as follows with the drawings.
[0021] Please refer to Figure 3A ~ Figure 3J , which shows a schematic cross-sectional...

The present invention relates to a soft circuit board which can be identified, including flexible base board, conductive circuit and printing ink layer. The conductive circuit is arranged on one surface of the base board, and said surface is covered with said printing ink layer by means of coating, exposure and developing mode, and at least part of the conductive circuit can be exposed, and said printing ink layer has at least identification zone for identification on the production line.
Description
technical field [0001] The invention relates to a flexible circuit board, in particular to an identifiable flexible circuit board. Background technique [0002] Color ink jet printer has become an indispensable part in the daily life of modern people. For example, users can use a color inkjet printer to print required documents and patterns, which is very convenient. Among them, the general color inkjet printers are equipped with two ink cartridges (Cartridge), one is a black (Black) ink cartridge, and the other is a color (Color) ink cartridge, which are used to fill inks of different colors and serve as ink cartridges. ink for printing. The ink cartridge is usually equipped with a flexible circuit board, which is used to guide the driving current of the printer into the chip (Chip) of the ink cartridge, so that the chip can control the ink cartridge according to the driving current of the printer to perform inkjet printing. In addition, the flexible circuit board has se...
