High-durability two-stage snake-shaped interconnected wire structure

Abstract

The invention discloses a high-durability two-stage snake-shaped interconnected wire structure which comprises a plurality of first-stage snake-shaped wire structures connected in sequence, and everytwo adjacent first-stage snake-shaped wire structures are connected together through an arc-shaped wire to form a two-stage snake-shaped interconnected wire structure. In the invention, the two adjacent first-stage snake-shaped wire structures are connected by adopting the arc-shaped wire with the same width as the wires of the first-stage snake-shaped wire structures. When the wire is stretched,the arc-shaped wire can provide a transverse stretching amount required by stretching so that a stretching burden on a wire material is reduced, strain concentration in the wire material can be decreased, the durability of the wire is improved, and compared with an original connecting structure of a linear wire, the structure can provide a larger stretching amount. Moreover, the arc-shaped wire adopted by the structure can be prepared only by adopting an original process, and the manufacturing is simple and convenient for preparing the wire by adopting a new process.

Description

technical field [0001] The invention relates to a two-stage serpentine interconnection wire structure, in particular to a highly durable two-stage serpentine interconnection wire structure. Background technique [0002] With the continuous innovation and development of medical electronics, brain-computer interface, solar chips, industrial electronics and other fields and the continuous improvement of the requirements of practical application scenarios, the traditional planar electronic devices composed of rigid circuit boards are difficult to meet the requirements of practical applications, so flexible electronics Technology came into being. Flexible electronics, also known as flexible circuits, is an electronic device mounted on a flexible plastic substrate (such as polyimide, polyetheretherketone or polyethylene terephthalate, etc.), and assembled using a special wire structure Technology of electronic circuits. Flexible electronics have a wide range of applications in t...

Problems solved by technology

However, the primary connection area of ​​the traditional two-stage serpentine wire structure is a straight wire. When the wire is unfolded in the second stage, since the straight wire cannot provide the stretching amount for deformation, the strain will be concentrated in the first-level wire connection area, thereby reducing the strain.
