Flexible printed circuit board and ink jet recording head using the same |
摘要 |
A flexible printed circuit board has a copper foil serving as a conductive pattern, a nickel layer and a gold layer stacked in sequence on a base film made of polyimid at an area to be electrically connected by wire bonding. The wire bonding is made by an aluminum wire and the nickel layer having a thickness of 10 mu m to 20 mu m. An ink jet recording head for discharging ink droplets from a discharge port onto a recording medium for recording thereon is electrically connected to an ink discharge unit by the flexible printed circuit board. <IMAGE> |
