摘要： PURPOSE:To remove a gap between a mold and a frame at the time of resin seal and prevent formation of resin varias, by holding a lead frame with a jig and applying plating to an exposed part in an opening on one surface after a selective grinding. CONSTITUTION:A jig body 10 and 14 consist of Si rubber etc. The jig body 10 and a fixed plate 12 have overlapped opening part 11, 13. The jig body 14 has no opening and a press plate is stacked thereon. A lead frame 1 is held between the plates 12, 15 with the intervention of the jig body 10, 14, and the whole parts are made into a monolithic body. Then the opening part is faced with a nozzle 24, and the abrasive solutions are jetted to a region 8 to be a plated region, which is activated by chemical abrasion. After washing the plating solutions are jetted to plate the region 8. Thereafter the jig body is removed and after washing and drying a frame 31 is completed. With such an arrangement, no gap is caused between a mold and a frame at the time of resin seal, because the unplated area retains the original thickness. Thus no resin varias occur.

摘要： PROBLEM TO BE SOLVED: To provide the new coating technology related to fuel cell separator. SOLUTION: A fuel cell separator 10 is provided with an opening 14 serving as a manifold. The resin coating is applied over the peripheral border area of the fuel cell separator 10, with the power generation region masked by a masking jig. At this time, the resin coating is applied so that a separator base material is exposed at a part of the peripheral border area. Subsequently, the masking jig is removed, then the conductive coating is applied over the power generating region of the fuel cell separator 10, with its peripheral border area being masked by the resin coating. At this time, the conductive coating is energized via the portion where the separator base material is exposed at a part of the peripheral border area. COPYRIGHT: (C)2008,JPO&INPIT
