Abstract:
A wiring board insertion connector having only a small restriction on the structure of a wiring board to be inserted to the connector and high connection reliability includes a first substrate; a second substrate; a spacer layer that is located between the first substrate and the second substrate; and openings for accommodating a wiring board at predetermined positions in the spacer layer. The first substrate has a wiring layer, a deformable layer, a rigid layer, and a resin layer formed in this order from the side of the spacer layer. The rigid layer has window portions formed at the regions corresponding to the openings, when seen from a thickness direction of the connector. The wiring layer extends at least to the regions corresponding to the window portions when seen from the thickness direction of the connector, the wiring layer protruding toward opening regions at the window portions.
Abstract:
A method of at least one embodiment of the present invention for packing a TAB tape is a method in which the TAB tape is wound on a core reel so as to be packed, the TAB tape being a tape-shaped insulating film on which circuits are provided in a repeated manner, the circuits each of which is made up of metal wiring and a solder resist. In at least one embodiment, the method includes a first step of winding at least the TAB tape on an outer peripheral surface of a core reel having a cylindrical shape, the core reel having a shaft hole on its inner peripheral side. This makes it possible to provide (i) a method for packing a TAB tape which method makes it possible to reduce a packing size, and (ii) a smaller packing structure for a TAB tape.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a tape carrier for TAB capable of carrying out screen printing of solder resist with high precision while suppressing an increase in the number of steps and waste of material. SOLUTION: Positioning marks PM1 and PM2 are formed on both sides of each printing block 13 on the tape carrier 1 for TAB. In screen printing, a long-shaped circuit substrate 10 is transported by a roll-to-roll system. When an optical sensor detects the positioning mark PM1, the transport of the long-shaped circuit substrate 10 stops. Then, a screen printing device 100 carries out screen printing of solder resist on the printing blocks 13 of the long-shaped circuit substrate 10. COPYRIGHT: (C)2009,JPO&INPIT
