Abstract
Abstract A first die having a relief pattern is employed to provide predetermined shape and relative positioning for a first plurality of metal strips. A second die is similarly employed for a second plurality of metal strips Without removing the metal strips from the dies, the strips, still in predetermined shape and position, are bonded to opposing surfaces of an insulating substrate. The bonding process includes bringing the dies, and hence, the metal strips, into contact with the opposing surfaces of the insulating substrate. The bonding process may include the application of heat, pressure, and an electrical field across the bonding interfaces, e.g., anodic bonding.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
120 words
A method of forming a metal pattern on at least one surface of a solid insulating substrate, comprising the steps of: (a) pressing a plurality of metal strips into contact with a die having a predetermined relief pattern thereon and conforming the strips to at least portions of said die so as to shape and position said strips in accordance with said relief pattern and releasably securing the strips to said die; and then (b) placing said surface of said solid insulating body into contact with said shaped and positioned metal strips while holding said strips on said die in said predetermined position and holding the insulating body against said strips until said strips are bonded to said insulating body.
Claim 2
Independent Claim
120 words
A method of forming a metal pattern on at least one surface of a solid insulating substrate, comprising the steps of: (a) pressing a plurality of metal strips into contact with a die having a predetermined relief pattern thereon and conforming the strips to at least portions of said die so as to shape and position said strips in accordance with said relief pattern and releasably securing the strips to said die; and then (b) placing said surface of said solid insulating body into contact with said shaped and positioned metal strips while holding said strips on said die in said predetermined position and holding the insulating body against said strips until said strips are bonded to said insulating body.
Claim 3
Dependent Claim
53 words
A method in accordance with claim 1 in which said predetermined relief pattern comprises a plurality of discrete strip relief patterns, each of which corresponds to a separate one of said metal strips, wherein step a) includes bringing separate ones of said metal strips into contact with said corresponding discrete strip relief patterns.
Claim 4
Dependent Claim
31 words
A method in accordance with claim 2 in which step a) includes applying pressure on said metal strips so as to cause said strips to conform to said die relief patterns.
Claim 5
Dependent Claim
19 words
A method in accordance with claim 3 which includes applying pressure incrementally along the length of said metal strips.
Claim 6
Dependent Claim
31 words
A method in accordance with claim 4 in which said die includes a substantially flat surface having said relief patterns thereon which method includes moving a roller across said metal strips.
Claim 7
Dependent Claim
20 words
A method in accordance with claim 3 in which step a) includes substantially preventing lateral spreading of said metal strips.
Claim 8
Dependent Claim
25 words
A method in accordance with claim 3 in which step a) includes providing a substantially uniform pressure distribution between said die and said metal strips.
Claim 9
Dependent Claim
18 words
A method in accordance with claim 3 in which step b) includes the application of heat and pressure.
Claim 10
Dependent Claim
14 words
A method in accordance with claim 8 in which step b) includes anodic bonding.
Claim 11
Dependent Claim
21 words
A method in accordance with claim 3 in which step a) is separately performed with at least two of said dies.
Claim 12
Dependent Claim
31 words
A method in accordance with claim 10 in which step b) comprises bonding said shaped and positioned metal strips on each of said dies to opposing surfaces of said insulating body.
Claim 13
Dependent Claim
18 words
A method in accordance with claim 11 in which step b) includes the application of heat and pressure.
Claim 14
Dependent Claim
14 words
A method in accordance with claim 12 in which step b) includes anodic bonding.
Claim 15
Independent Claim
115 words
A method of forming a metal pattern on a solid insulating substrate, comprising the steps of: (a) forming a plurality of metal strips from a foil of said metal; (b) pressing said metal strips into contact with a die having a predetermined relief pattern thereon and conforming the strips to at least portions of said die so as to shape and position said strips in accordance with said relief pattern and releasably securing the strips to said die; and (c) bringing said strip containing die into pressing contact with said solid insulating body and holding the insulating body against said strips so as to bond said shaped and position metal strips to said insulating body.
Claim 16
Independent Claim
115 words
A method of forming a metal pattern on a solid insulating substrate, comprising the steps of: (a) forming a plurality of metal strips from a foil of said metal; (b) pressing said metal strips into contact with a die having a predetermined relief pattern thereon and conforming the strips to at least portions of said die so as to shape and position said strips in accordance with said relief pattern and releasably securing the strips to said die; and (c) bringing said strip containing die into pressing contact with said solid insulating body and holding the insulating body against said strips so as to bond said shaped and position metal strips to said insulating body.
Claim 17
Dependent Claim
44 words
A method in accordance with claim 14 in which step b) is separately performed with two of said dies and in which step c) comprises bonding said shaped and positioned metal strips on each of said dies to opposing surfaces of said insulating body.
Claim 18
Dependent Claim
19 words
A method in accordance with claim 15 in which one of said dies is more rigid than the other.
Claim 19
Dependent Claim
14 words
A method in accordance with claim 15 in which said insulating body comprises glass.
Claim 20
Dependent Claim
15 words
A method in accordance with claim 17 which includes the application of heat and pressure.
Claim 21
Dependent Claim
16 words
A method in accordance with claim 18 in which said insulating body comprises soda-lime silicate glass.
Claim 22
Dependent Claim
14 words
A method in accordance with claim 9 in which step c) includes anodic bonding.
