  • Optical color tracer indentifier in metal paste that bleed to greensheet
    Patent number: 6521355
    Abstract: A coating material used in the fabrication of electronic components such as a metallized paste is provided comprising a material to be coated on the electronic component substrate and an identifying component which identifying component can be identified and which identifying component identifies the coating material. Optical dyes visible to the eye can be used as the identifying component with a preferred dye being a UV fluorescent dye which is colorless under visible light and visible under UV light. A process for making an electronic component using the coating materials of the invention and electronic components made using the coating material are also provided.

  • Process for via fill
    Patent number: 5927193
    Abstract: An apparatus and method is provided for vacuum screen printing a greensheet having vias and both vias and open areas whereby vacuum leakage in the apparatus is minimized and avoids bowing of the screen over the open area of the greensheet. An interposer apparatus is provided comprising at least two layers having vertical through openings in registration with the via openings of the greensheet and screen. The interposer also comprises vertical through openings communicating with the open area of the greensheet and with vent channels of the interposer. A porous membrane is also used either alone or in conjunction with the interposer to provide enhanced screening results.

  • Method for screening using electrostatic adhesion
    Patent number: 5635000
    Abstract: The present invention relates generally to a new apparatus and method for screening using electrostatic adhesion. More particularly, the invention encompasses an apparatus that uses an electrostatic charge during the screening process for a semiconductor substrate. Basically, a backing layer is adhered to a green ceramic sheet using an electrostatic charge, while the green ceramic sheet is processed.
