Flexible stretchable circuit and manufacturing method thereof

Abstract

The invention provides a flexible stretchable circuit and a manufacturing method thereof, and relates to the technical field of electronics. The manufacturing method comprises: S1, providing a hard base material, and forming a low-melting-point metal circuit on the surface of the hard base material; S2, forming a first packaging material layer on the low-melting-point metal circuit, wherein the first packaging material layer is used as a flexible stretchable base material in a flexible stretchable circuit; S3, placing the obtained structure in a first environment until the flexible stretchablebase material completes glass transition; S4, placing the obtained structure in a second environment, separating the flexible stretchable base material from the hard base material, and attaching thelow-melting-point metal circuit to the flexible stretchable base material; S5, forming a second packaging material layer on the low-melting-point metal circuit in a second environment; and S6, placingthe obtained structure in a third environment to obtain the flexible stretchable circuit. According to the technical scheme, the flexible stretchable circuit can be manufactured so as to meet the requirements on flexibility and stretchability of the circuit at the same time.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a flexible and stretchable circuit and a manufacturing method thereof. Background technique [0002] As an emerging electronic device, flexible circuits are widely used in smart wear, artificial skin, foldable electronic devices and other fields. At present, mainstream flexible circuits are mainly based on conductive materials such as copper wires, aluminum foil, and silver paste. The devices produced can meet basic requirements such as bending and shearing, but due to the limitations of conductive materials, they cannot meet the needs of high-strength stretching. Contents of the invention [0003] The invention provides a flexible and stretchable circuit and a manufacturing method thereof, which can make a flexible and stretchable circuit, so as to meet the requirements for flexibility and stretchability of the circuit at the same time.
