Problems solved by technology

In the process of realization, cumbersome procedures, huge initial equipment investment and huge human resources are required to realize the output of PCB
In order to solve the above technical problems, in the prior art, circuit boards can be made by directly printing liquid metal lines with low melting point on the substrate, but the circuit boards produced are easy to bend and deform, making the circuit invalid. Reasons include stripping of liquid metal lines, disconnection of components and liquid metal lines at the soldering position, etc., and poor structural stability of the circuit board

Abstract

The invention provides a manufacturing method of a circuit board, and relates to the technical field of electronic circuits. The manufacturing method of the circuit board provided by the invention comprises the following steps: S1, forming a first conductive circuit on a first surface of a flexible first substrate in a direct printing manner; and S2, forming a second substrate on the second surface of the first substrate, wherein the second substrate is used for improving the hardness of the circuit board. According to the technical scheme, the manufacturing process of the circuit board can besimplified, and the structural stability of the circuit board is improved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a method for manufacturing a circuit board. Background technique [0002] The traditional PCB board-making process requires large-scale high-precision equipment for board-making processes such as material cutting, copper sinking, etching, solder mask, and surface treatment. In the process of realization, cumbersome procedures, huge initial investment in equipment and huge human resources are required to realize the output of PCB. In order to solve the above technical problems, in the prior art, circuit boards can be produced by directly printing liquid metal lines with low melting point on the substrate, but the produced circuit boards are easy to bend and deform, which makes the circuit invalid. The reasons include the stripping of the liquid metal circuit, the disconnection of components and liquid metal circuit welding positions, etc., and the structural stability...
