STRETCHABLE CIRCUIT BOARD AND STRETCHABLE CIRCUIT BOARD FABRICATING METHOD

摘要

The present invention forms a circuit pattern comprising one or more mounting pad units for mounting electronic components on a polyimide (PI) film of a certain size and a wiring pattern for circuitly connecting the mounting pad units, and the outline of the circuit pattern Manufacturing a flexible board (FPCB) made of a cutting line for cutting silver, a component mounting step of mounting an electronic component designated on a circuit pattern of the flexible board, and a punching jig aligned with the cutting line of the flexible board on which the component is mounted ( The present invention relates to a stretchable substrate having excellent tensile performance of wiring connecting circuits, and a method for manufacturing the stretchable substrate, comprising a punching step of cutting the cutting line using a punching jig).
