Method for performing flexible electronic patterning on pretensioning elastic base plate

Abstract

The invention discloses a method for performing flexible electronic patterning on a pretensioning elastic base plate. The method comprises the following steps: (1) stretching the elastic base plate at a certain strain rate in the horizontal direction; (2) calculating coordinates corresponding to each point under the stretching state on the elastic base plate under the natural state, thus coordinates corresponding to the coordinates of discrete components which form anticipated regular patterns under the natural state are obtained, and interconnection structures under the stretching state relative to the interconnecting structures under the natural state are obtained; (3) placing the discrete components on the corresponding coordinates under the stretching state, and distributing the interconnecting structures on the interconnection structure corresponding to the stretching state; and (4) releasing the base plate, thus the flexible electronic patterns which are distributed uniformly can be obtained. According to the invention, the coordinate conversion for the discrete components from the stretching state to the free state can be finished, a mask film is not required to be manufactured, also a higher visual alignment function is not required, the process is simple, the cost is lower, and the flexibility of pattern design of a flexible electronic device is improved greatly.

Description

technical field [0001] The invention relates to a method for arranging discrete electronic components and interconnection structures, in particular to a method for arranging discrete electronic components and interconnection structures on a pre-stretched elastic substrate, so that when the substrate releases the pre-strain, the electronic components Can form the expected graphics. Background technique [0002] Flexible electronics refers to arranging or embedding circuits on bendable / stretchable flexible substrates, so that electronic products can withstand large bending, stretching, and torsional deformation. Typically, various polymers are selected as flexible substrate materials due to their good deformability and better insulation properties. The circuit to be arranged or embedded can be a flexible circuit with the ability to deform itself, or a traditional rigid circuit. Flexible electronics try to bionic design human skin, muscles, etc., so that electronic products c...
