Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0032] See Figure 1 to Figure 3 , as shown, a novel flexible printed circuit manufacturing method, its specific manufacturing implementation methods and steps are as follows:

[0033] (1) Selection and preparation of substrates and conductive inks

[0034] The selection of substrates includes but is not limited to textile fibers, organic polymer materials (PI, PET, PP, etc.), glass and other substrate materials that can print conductive ink. According to the traditional substrates in the current market, organic polymer materials such as PI and PET with certain flexibility are preferred as the substrate for research. Conductive ink options include, but are not limited to, metall...

Abstract

The invention discloses a method for manufacturing a novel flexible printed circuit. The invention discloses a method for manufacturing a novel flexible printed circuit. The method comprises coveringa base material required to prepare a flexible circuit with a patterned mask, wherein the mask is hollowed out and has a patterned circuit; by using the ultrasonic precision atomization spraying technology, ultrasonically atomizing configured nano-conductive ink, and generating micron-order fine droplets at a nozzle; at the same time, adding a certain pressure of compressed air to uniformly coat the base material covered with the mask with the ink mist drops under the guidance of an airflow; and according to the nature of the nano-conductive ink, annealing and sintering the base material so asto complete the preparation of the flexible circuit. The method can meet the requirements for flexible circuits on the market, and can control the spraying thickness and adapt to different base material. The present invention provide a new idea for the preparation process and method of the flexible circuit board.

Description

technical field [0001] The invention relates to the field of printed electronics, in particular to a method for manufacturing a novel flexible printed circuit. Background technique [0002] With the rapid development of our economy and the improvement of people's living standards, the demand for electronic products is also expanding. Electronics are so integral to our lives today that in some ways we depend on them more than ever. An essential part of all these electronic products is the printed circuit board (PCB). my country is the largest country in the world in PCB production, ranking first in both total output value and total output. Last year, the output value reached more than 558.4 billion yuan. The production of boards has thus become an important industry in the information industry. However, most of the traditional PCB manufacturing processes use the etching subtractive method, resulting in high pollution and low technical content. As a new manufacturing technolo...
