Description

  The present invention relates to a carrier for transporting a flexible printed circuit board and a printing apparatus for a flexible printed circuit board using the carrier.

  Conventionally, since a flexible printed board is a thin film-like board, twisting and warping are likely to occur by itself, and thus a jig called a carrier for carrying a board is generally used. And when fixing a flexible printed circuit board to the carrier for conveyance, the method of hold | maintaining a board | substrate to the carrier for conveyance with the adhesive force may be employ | adopted using the silicone type resin material containing siloxane as an adhesive material. In the electric / electronic field, the silicone-based resin material containing siloxane adheres to the surface of an electrical contact such as a terminal, and becomes an insulating film, resulting in contact failure, causing poor conduction and malfunction. There is a problem. In addition, even in the carrier carrier adhesive material that does not contain siloxane, the adhesive material made of resin material loses its adhesiveness by being used a certain number of times in a reflow furnace, etc. The problem that it becomes necessary occurs.

  Further, as a conventional technique, in a flexible printed circuit board carrier on which a flexible printed circuit board for double-sided mounting is mounted on the upper surface, the upper surface is provided with a recessed portion for accommodating components mounted on the lower surface of the flexible printed circuit board, and the recessed portion is accommodated. There is known a flexible printed circuit board carrier that has a depth corresponding to the component thickness of the fixture and supports the component on the bottom surface (see, for example, Patent Document 1).
