摘要:
Connection pads and alignment marks are formed on a long metal thin plate that is carried in a longitudinal direction, and then an insulating layer for covering the connection pads is formed. Then, via holes, which are aligned and arranged on the connection pads by utilizing the alignment marks, are formed in portions of the insulating layer. Then, n-layered (n is an integer of 1 or more) wiring layers connected to the connection pads via the via holes are formed, and the connection pads and the insulating layer are exposed by removing the metal thin plate.

A wiring layer forming wirings containing inner leads and outer leads are formed on a flexible substrate. Then, inner lead reinforcing electrodes to which a semiconductor chip is connected are formed on the inner leads, outer lead reinforcing electrodes are formed on the outer leads, and wiring reinforcing portions are formed between the inner leads and the outer leads on the wiring layers. The flexible substrate is mounted onto an electronic device by folding a portion to which the wiring reinforcing portions are provided between the inner leads and the outer leads.

There is provided a system for readily and efficiently fabricating a wound coil composed of a bobbinless coil. The system includes a coil winding device having an upper jig to which an upper plate is attached and a lower jig to which a lower plate is attached which are provided so as to be relatively displaceable and a tension device for applying predetermined tension to a wire rod fed from a wire rod supplying source. The coil winding device is provided with a claw section having first through third split claws that function as a winding section around which the wire rod is wound between the upper and lower plates and that slide in a radial direction when the upper jig is assembled coaxially with the lower jig.

A method of manufacturing a flexible wiring substrate of the present invention includes the steps of preparing a tape-like substrate composed of a resin layer and a reinforcing metal layer provided on its lower surface, then forming a via hole whose depth reaches the reinforcing metal layer by processing the resin layer of the tape-like substrate by the laser, and then forming a wiring pattern which is connected to the reinforcing metal layer through the via hole on the resin layer by the semi-additive process, wherein the reinforcing metal layer is patterned to constitute a connection pad connected to the wiring pattern or is removed.
