Problems solved by technology

When the flexible circuit board needs to pass through the electronic shaft structure, it is usually necessary to reserve space for the stretching length of the flexible circuit board, and when the flexible circuit board passes through the shaft hole, the displacement direction will be limited and cannot withstand multi-directional stress

Embodiment Construction

[0073] In order to make the technical means of the present invention and the effects it can achieve more completely and clearly disclosed, the detailed description is as follows. Please also refer to the disclosed drawings and drawing numbers:

[0074] see figure 1 , shows a schematic structural view of the stretchable flexible circuit board according to the first embodiment of the present invention. As shown in the figure, the stretchable flexible circuit board 100 includes a flat first connecting section 101 and a first end 101 a formed at one end of the first connecting section 101 . A second end portion 102a is also formed at one end of the flat second connecting section 102 . Between the first connecting section 101 and the second connecting section 102 is connected an extending section 103 which is flat and extends along an extending direction M. As shown in FIG. The extending section 103 extending in an extending direction M means that two ends of the extending sectio...

Abstract

A flexible circuit board includes a first connection section and a second connection section between which a stretchable extension section is connected and has at least a portion that is shapeable by a shapeable material layer to form a spiral section. The spiral section is stretchable in the extension direction. The spiral section provides the flexible circuit board with characteristics of better flexibility, stretchability, capability of eliminating stresses induced in multiple directions.

Description

technical field [0001] The present invention relates to a flexible circuit board, in particular to a stretchable flexible circuit board. The stretchable flexible circuit board includes at least one helix in the extension section of a flexible substrate. Shaped section, so that the extension section can be stretched along the extension direction, the structure of multi-directional stress. Background technique [0002] In various electronic devices used today, since the transmission volume of signal lines is increasing, more and more signal transmission lines are required. In the signal transmission line bundle technology, the flexible circuit board is the most developing technology at present. The flexible circuit board has the characteristics of light weight and small size. It is mainly to meet the assembly conditions of various external system products. Improve wiring density characteristics As a circuit carrier for signal connection or component assembly, since the flexib...
