Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A method of manufacturing a ceramic article having raised electrical terminals comprising the steps of providing a body of unfired ceramic material having a predetermined metallized electrical pattern on at least a portion of an external surface; providing a sheet of unfired ceramic material bearing a predetermined array of electrical contacts which are selectively metallized on at least a portion of their horizontal surfaces; separating said electrical contacts from said sheet and contacting said terminals to said body to provide an unfired ceramic structure having electrical interconnection between said pattern and said contacts; and firing said structure to maturity.
Claim 2
Independent Claim
99 words
A method of manufacturing a ceramic article having raised electrical terminals comprising the steps of providing a body of unfired ceramic material having a predetermined metallized electrical pattern on at least a portion of an external surface; providing a sheet of unfired ceramic material bearing a predetermined array of electrical contacts which are selectively metallized on at least a portion of their horizontal surfaces; separating said electrical contacts from said sheet and contacting said terminals to said body to provide an unfired ceramic structure having electrical interconnection between said pattern and said contacts; and firing said structure to maturity.
Claim 3
Dependent Claim
38 words
A method according to claim 1 wherein, prior to separating said electrical contacts from said sheet, said body and said sheet are indexed so that said electrical pattern and said array of electrical contacts are in desired registry.
Claim 4
Dependent Claim
19 words
A method according to claim 1 wherein said body of unfired ceramic material is provided in an array format.
Claim 5
Dependent Claim
18 words
A method according to claim 1 wherein a portion of the vertical surfaces of said array are metallized.
Claim 6
Dependent Claim
18 words
A method according to claim 1 wherein said electrical contacts are totally metallized on their exposed horizontal surfaces.
