<P>PROBLEM TO BE SOLVED: To provide a wiring circuit substrate on which a conductive pattern having high reliability is mounted, and an electronic component is accurately mounted, and also to provide a method for manufacturing the wiring circuit substrate, and for mounting the electronic component. <P>SOLUTION: An insulating layer 3 having a mounting portion 10 is formed on a metal supporting layer 2 whose specular gloss at an incident angle 45° is 150-500%, and a conductive pattern 4 is formed on the insulating layer 3 to inspect a quality of figure of the conductive pattern 4 by a reflective optical sensor 24. Then, a portion layered with a mounting portion 10 on the metal supporting layer 2 is etched to form an opening 16 so that a haze value of the insulating layer 3 of the mounting portion 10 exposed by etching is 20-50%, then a tape carrier 1 for TAB is obtained. Then, the electronic component 21 and the mounting portion 10 are positioned by a reflective type optical sensor 29 to mount the electronic component 21 on the mounting portion 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
