Claims
- 1. A method of forming transmission lines and openings for buried passive components in green tapes comprising
embossing a channel or opening in a green tape using an embossing tool having a desired pattern thereon using heat and pressure sufficient to transfer the pattern from the embossing tool to the green tape, and screen printing a suitable ink into the channels or openings to a desired thickness.
- 2. A method according to claim 1 wherein embossed transmission line channels are filled with a conductive ink.
- 3. A method according to claim 2 wherein the conductive ink includes silver powder and an organic vehicle to provide a viscosity of about 30 poise.
- 4. A method according to claim 1 wherein embossed openings are made in a green tape and screen printed to fill the opening using a resistor ink.
- 5. A method according to claim 1 wherein embossed openings are made in a green tape and screen printed to fill the opening using a capacitor ink.
- 6. A method according to claim 5 wherein said capacitor ink includes lead magnesium niobate.
- 7. A method according to claim 5 wherein said capacitor ink includes barium titanate.
- 8. A method according to claim 4 wherein said resistor ink includes ruthenium oxide.
- 9. A method of making buried passive components comprising
a) embossing an opening of a desired size in a green tape; b) filling said opening by screen printing an ink including said component material; c) burying said green tape in a green tape stack; d) aligning and laminating said stack onto a support board coated with a low melt temperature glass; and e) firing said stack to remove organic materials and to densify the glass of the green tape.
- 10. A method according to claim 9 wherein said support board is of metal.
- 11. A method according to claim 1 wherein a pattern of embossed openings are made in a green tape and screen printed to fill the pattern with a conductive ink to form inductors of high Q.
- 12. A method according to claim 1 where a pattern of embossed openings are made in a green tape and filled with conductive ink to form filters of high Q.
