RIGID-FLEXIBLE SUBSTRATE AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a rigid-flexible substrate in which flexibility and elasticity of a flexible part is not impaired even if wiring density is increased, which comprises a simple process, and which provides a high material yield and a high product yield. SOLUTION: A rigid substrate having a vertical wiring formed in a joint region and a flexible substrate having a connection terminal formed at an end are separately manufactured. Positions of the rigid substrate corresponding to the edges of both surfaces of the flexible substrate are spot faced equally to or deeper than the thickness of the flexible substrate to form steps. The connection terminal of each one end of two flexible substrates is connected to the vertical wiring of the step. COPYRIGHT: (C)2006,JPO&NCIPI
