PROBLEM TO BE SOLVED: To provide a method of positioning a rolled flexible board in an automated manufacturing process. SOLUTION: The method particularly uses an optical sensor to sense two edges of the rolled flexible board, lateral direction coordinate information, and longitudinal direction coordinate information; precisely forms positioning holes by using the coordinate information items sensed earlier; and uses the positioning holes to precisely determine a start point of a succeeding working area, so that a gap between two working areas is not too large nor too small. In applying a micro-via processing and an image transfer process to the rolled flexible board on the basis of the coordinate information items, the occurrence of deviation and inclination can be avoided.

PROBLEM TO BE SOLVED: To provide a thin plate support jig.SOLUTION: A thin plate support jig used for supporting a thin plate according to the present invention includes a main frame, a support underlay material, a coupling body, and at least two elastic supports. The main frame is provided with four side frames so that they surround a hollow area. The support underlay material extends in a hollow area direction from an inner wall of the side frame, and stationary pins are provided on the respective support underlay materials corresponding to stationary holes on the thin plate. The coupling body is provided at a portion of a recess on the side frame. Each elastic support body is fixed by the two coupling bodies, and at least two elastic supports are aligned to cross with each other, and support the thin plate across the hollow area with elasticity. Thereby, utilization efficiency of the entire thin plate is improved, so as to reduce residue of a medicine and scratches, and improve a yield. Also, because a conventional facility is utilized, there is no need of purchasing a new holding tool, and therefore, facility costs are significantly reduced, so as to improve applicability and production efficiency in a manufacturing step, and further equalize a current density during electric plating.

PROBLEM TO BE SOLVED: To provide a flexible printed wiring board (FPC) and a manufacturing method thereof. SOLUTION: In the flexible printed wiring board and the manufacturing method thereof, the wiring board is mainly constituted of a polyimide (PI) substrate 10 with a circuit layer 12 and a polyimide substrate 14 formed by pressing an adhesive 16 on a polyimide board. In the invention, a method for etching a polyimide board is employed for conductively connecting the circuit layer 12 on a polyimide board, and a precision fine continuity hole 18 is formed on the circuit layer 12. A method wherein a continuity hole is subjected to punch processing in advance on a polyimide substrate for pressing it on a polyimide board is not employed. Consequently, a mold cost is cut and position accuracy in relation to a circuit layer of a continuity hole is raised simultaneously. COPYRIGHT: (C)2009,JPO&INPIT
