Abstract:
A method and apparatus are provided for filling vias in a product greensheet and/or repairing vias in a product greensheet. The method and apparatus utilize a transfer greensheet having filled vias in a fixed array, which vias are punched into the product greensheet to either repair or fill the via of the product greensheet. The method and apparatus employ position determining means such as a camera, a punch head and a corresponding punch die and an activating means to activate the punch head to punch the transfer greensheet via to fill the product greensheet via. The transfer greensheet has a fixed array of filled vias and a transfer greensheet station employs a fixed plate having a plurality of vacuum ports positioned in the non-via areas of the transfer greensheet which secures the transfer greensheet during the method. The product greensheet is held by a vacuum plate.
