Abstract
Abstract A pattern of conductor runs is formed on a sheet of dielectric material using a carrier foil having a coating material adhered to one main surface thereof. The coating material contains particles of metal. The carrier foil is placed with its coated surface in contact with the sheet. The coating material is detached from the carrier foil over selected areas of its coated surface, and the detached coating material is adhered to the sheet.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
87 words
A method of forming a pattern of conductor runs on a receiver sheet of dielectric material, comprising: (a) providing a transfer sheet comprising a carrier foil having a metal-containing coating adhered to one main face thereof, and a receiver sheet of green ceramic material, (b) placing the transfer sheet with the coating in contact with the receiver sheet, and (c) detaching the coating material from the carrier foil over selected areas of said one main face thereof and adhering the detached coating material to the receiver sheet.
Claim 2
Independent Claim
87 words
A method of forming a pattern of conductor runs on a receiver sheet of dielectric material, comprising: (a) providing a transfer sheet comprising a carrier foil having a metal-containing coating adhered to one main face thereof, and a receiver sheet of green ceramic material, (b) placing the transfer sheet with the coating in contact with the receiver sheet, and (c) detaching the coating material from the carrier foil over selected areas of said one main face thereof and adhering the detached coating material to the receiver sheet.
Claim 3
Dependent Claim
24 words
A method according to claim 1, further comprising firing the ceramic material after the detached coating material has been adhered to the receiver sheet.
Claim 4
Dependent Claim
21 words
A method according to claim 1, wherein the coating material comprises particles of metal embedded in a matrix of organic material.
Claim 5
Dependent Claim
13 words
A method according to claim 3, wherein the organic material comprises a wax.
Claim 6
Dependent Claim
47 words
A method according to claim 4, further comprising heating the green ceramic material in an atmosphere containing oxygen after the detached coating material has been adhered to the receiver sheet, whereby the wax decomposes, and firing the green ceramic material, whereby the metal bonds to the ceramic.
Claim 7
Dependent Claim
50 words
A method according to claim 1, wherein step (a) is performed by mixing particles of metal with a wax material in a liquid state, casting the liquid wax material with the metal particles suspended therein to form a solid, and applying a coating of the solid to said carrier foil.
Claim 8
Dependent Claim
31 words
A method according to claim 1, wherein step (c) is performed by applying pressure to the transfer sheet over an extended area thereof and applying heat locally to the transfer sheet.
Claim 9
Dependent Claim
19 words
A method according to claim 1, wherein step (c) is performed by locally applying pressure to the transfer sheet.
Claim 10
Independent Claim
90 words
A method of forming a pattern of conductor runs on a receiver sheet of dielectric material, comprising: (a) providing a transfer sheet comprising a carrier foil having a coating adhered to one main face thereof, said coating comprising particles of metal embedded in a matrix of wax, (b) placing the transfer sheet with the coating in contact with the receiver sheet, and (c) detaching the coating material from the carrier foil over selected areas of said one main face thereof and adhering the detached coating material to the receiver sheet.
Claim 11
Independent Claim
90 words
A method of forming a pattern of conductor runs on a receiver sheet of dielectric material, comprising: (a) providing a transfer sheet comprising a carrier foil having a coating adhered to one main face thereof, said coating comprising particles of metal embedded in a matrix of wax, (b) placing the transfer sheet with the coating in contact with the receiver sheet, and (c) detaching the coating material from the carrier foil over selected areas of said one main face thereof and adhering the detached coating material to the receiver sheet.
Claim 12
Dependent Claim
35 words
A method according to claim 9, wherein the receiver sheet is green ceramic material, and the method further comprises firing the ceramic material after the detached coating material has been adhered to the receiver sheet.
Claim 13
Dependent Claim
33 words
A method according to claim 9, further comprising heating the receiver sheet in an atmosphere containing oxygen after the detached coating material has been adhered to the receiver sheet, whereby the wax decomposes.
Claim 14
Dependent Claim
50 words
A method according to claim 9, wherein step (a) is performed by mixing particles of metal with a wax material in a liquid state, casting the liquid wax material with the metal particles suspended therein to form a solid, and applying a coating of the solid to said carrier foil.
Claim 15
Dependent Claim
31 words
A method according to claim 9, wherein step (c) is performed by applying pressure to the transfer sheet over an extended area thereof and applying heat locally to the transfer sheet.
Claim 16
Dependent Claim
19 words
A method according to claim 9, wherein step (c) is performed by locally applying pressure to the transfer sheet.
