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.

Abstract: A method of dispensing a flowable conductive paste onto a greensheet from a dispensing apparatus comprising an orifice member having first and second surfaces and a bore therethrough between the surfaces, a pressurized chamber adjacent the orifice member first surface containing the paste, and a punch having a face movable through the orifice member bore. The method comprises positioning the punch outside the orifice member bore such that the punch face is spaced from the orifice member first surface, flowing a desired amount of paste onto the punch face, moving the paste on the punch face through the orifice member bore until the punch face extends beyond the orifice member second surface, and contacting the workpiece with the paste while still on the punch face to deposit the paste on the greensheet.

Abstract: An apparatus for providing uniform axial load distribution for laminate layers of multilayer ceramic chip carriers includes a base plate configured to support a plurality of green sheet layers thereon, the base plate having at least one resiliently mounted load support bar disposed adjacent outer edges of the base plate. The load support bar is mounted on one or more biasing members such that the top surface of the support bar extends above the top surface of the base plate by a selected distance.

Abstract: A method and structure to form surface plating metallization on a substrate. Two layers of tape are applied to the surface of the substrate. A first path is cut through both layers of tape exposing the substrate surface. The first path connects at least one conductive via on the top surface of the substrate. A second path is cut through the second layer of tape exposing the first layer of tape. The second path is routed from the first path to an edge of the substrate A seed layer is deposited over the surface of the second layer of tape thereby creating a seeded plating path in the first path and a sacrificial seeded conduction path in the second path. Connecting the sacrificial seeded conduction path to a plating potential at the edge of the substrate creates a plated path on the surface of the substrate. The sacrificial path is removed when the tape is removed.

Abstract: A die and method of gang punching selective holes in thin sheet materials such as greensheets are provided in which slugs of greensheet material formed during the punching operation easily fall through the die and are removed. The die uses a number of plates one of which is a window plate having openings corresponding to openings in a die plate disposed thereon. The window plate openings have a larger diameter than the die plate openings and also a plurality have an oval shape which oval shape openings provide less resistance to the falling slugs and facilitate removal of the slugs from the die. The window plate also preferably has a central grid open area with the remainder of the plate having vertical through-holes corresponding to the through-holes of the die plate. The die also preferably employs a die plate made from at least two sheets of material, i.e.

Abstract: The present invention relates to a method of fabricating electromagnetic coil vanes. The method utilizes laser machining to provide high resolution, dense coil wire patterns on both sides of a ceramic vane substrate. A firing operation is first performed that eutectically bonds the copper to the ceramic. Laser machining is then used to produce a coil pattern in the copper. The substrate is drilled to provide a through hole which, when filled or partially filled with a conducting material, forms an electrical connection between the two coil patterns.
