Abstract:
A method for manufacturing a semiconductor device is provided including: providing a reinforcing member on one surface of a wiring substrate that has a first region where a semiconductor chip is mounted and a second region around the first region, and has terminals extending from the first region to the second region formed on another surface thereof in a manner that the reinforcing member overlaps the terminals and a part thereof protrudes from the first region to the second region; cutting the terminals along a boundary between the first region and the second region; and continuously cutting the reinforcing member from an inboard side thereof to an outboard side along the boundary between the first region and the second region.

A method for manufacturing a semiconductor device is provided including: providing a reinforcing member on one surface of a wiring substrate that has a first region where a semiconductor chip is mounted and a second region around the first region, and has terminals extending from the first region to the second region formed on another surface thereof, in a manner that the reinforcing member overlaps the terminals and a part thereof protrudes from the first region to the second region; punching through from a surface side having the terminals in the wiring substrate, thereby cutting the terminals along a boundary between the first region and the second region; and punching through from the surface side having the reinforcing member in the wiring substrate, thereby continuously cutting the reinforcing member from an inboard side thereof to an outboard side along the boundary between the first region and the second region.
Abstract:
A method for manufacturing a flexible substrate includes punching out a flexible substrate from a flexible tape wherein the flexible substrate has a first contour that is a part of a contour of the flexible substrate, and a second contour that is a remaining portion of the contour other than the first contour, and requires a punching accuracy lower than a punching accuracy of the first contour. The method includes the steps of: operating a first die by a control section to punch out the first contour from the flexible tape; judging by the control section as to whether a punching accuracy of the first contour meets a standard; and operating a second die by the control section to punch out the second contour from the flexible tape thereby separating the flexible substrate from the flexible tape when the control section judges that the punching accuracy of the first contour meets the standard, and not operate the second die when the control section judges that the punching accuracy of the first contour does not meet the standard.
