Abstract
Abstract Methods of measuring the temperature of a surface or of various surfaces of work pieces and of a surface of a heating element or member coming in contact with the work pieces. A method of real time non-destructive testing of bonds during a bonding process is also disclosed. Leads are connected directly to the heating element or a hot member coming in contact with the work piece and to the work pieces to monitor electrical potentials generated along the surfaces which give an indication of the surface temperature. A ram specially adapted for real time measurement of these surface temperatures and for real time testing of bonds formed in a mechanical thermal pulse bonding process is also disclosed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
74 words
A method of measuring temperature between a first member and a hot member when said first member and said hot member are rapidly brought into contact with each other, comprising the steps of: connecting a lead to said first member; connecting a lead to said second member; and measuring the instantaneous transient electrical potential generated between said leads when said hot member and said first member are rapidly brought into contact with each other.
Claim 2
Independent Claim
74 words
A method of measuring temperature between a first member and a hot member when said first member and said hot member are rapidly brought into contact with each other, comprising the steps of: connecting a lead to said first member; connecting a lead to said second member; and measuring the instantaneous transient electrical potential generated between said leads when said hot member and said first member are rapidly brought into contact with each other.
Claim 3
Independent Claim
62 words
A method of measuring the temperature of a surface of a work piece contacted by a heated ram in a thermal bonding process, comprising the steps of: connecting a lead to said heated ram; connecting a lead to said work piece; and measuring an electrical potential generated between said leads when said heated ram is brought into contact with said work piece.
Claim 4
Independent Claim
62 words
A method of measuring the temperature of a surface of a work piece contacted by a heated ram in a thermal bonding process, comprising the steps of: connecting a lead to said heated ram; connecting a lead to said work piece; and measuring an electrical potential generated between said leads when said heated ram is brought into contact with said work piece.
Claim 5
Independent Claim
100 words
A method of real time non-destructive testing of a bond formed between two work pieces in a thermal bonding process wherein a heated ram contacts at least one of said two work pieces mounted on a support member, comprising the steps of: connecting a first lead to said heated ram; connecting a second lead to said one of said work pieces contacted by said heated ram; monitoring an electrical wave form appearing between said first and second leads when said heated ram contacts said one of said work pieces; and comparing said electrical wave form to a standard wave form.
Claim 6
Independent Claim
100 words
A method of real time non-destructive testing of a bond formed between two work pieces in a thermal bonding process wherein a heated ram contacts at least one of said two work pieces mounted on a support member, comprising the steps of: connecting a first lead to said heated ram; connecting a second lead to said one of said work pieces contacted by said heated ram; monitoring an electrical wave form appearing between said first and second leads when said heated ram contacts said one of said work pieces; and comparing said electrical wave form to a standard wave form.
Claim 7
Independent Claim
98 words
A method of measuring surface temperatures in a thermal bonding process wherein a first and a second work piece are mounted between a support member and a heated ram, comprising the steps of: mounting a metal ribbon between said heated ram and said first work piece; connecting a first lead to said heated ram; connecting a second lead to said metal ribbon; and measuring an electrical potential generated between said first and said second leads when said ram contacts said metal ribbon as an indication of the temperature of the surface of the ram contacting said metal ribbon.
Claim 8
Independent Claim
98 words
A method of measuring surface temperatures in a thermal bonding process wherein a first and a second work piece are mounted between a support member and a heated ram, comprising the steps of: mounting a metal ribbon between said heated ram and said first work piece; connecting a first lead to said heated ram; connecting a second lead to said metal ribbon; and measuring an electrical potential generated between said first and said second leads when said ram contacts said metal ribbon as an indication of the temperature of the surface of the ram contacting said metal ribbon.
Claim 9
Dependent Claim
64 words
A method of measuring surface temperatures as recited in claim 4 including the steps of: connecting a third lead to said first work piece; and measuring an electrical potential generated between said second and said third leads when said ram contacts said metal ribbon as an indication of the temperature of the surface of said first work piece in contact with said metal ribbon.
Claim 10
Dependent Claim
79 words
A method of measuring surface temperatures as recited in claim 5 including the steps of: mounting a second metal ribbon between said second work piece and said support member; connecting a fourth lead to said second metal ribbon; and measuring an electrical potential generated between said third and said fourth leads when said ram contacts said metal ribbon as an indication of the temperature of a surface of said second work piece in contact with said second metal ribbon.
Claim 11
Independent Claim
77 words
A method of measuring temperature of a hot member of electrically conductive material, comprising the steps of: connecting a first lead to said hot member at a point remote from the point at which the temperature is to be measured; contacting said Hot member at the desired temperature measurement point with a probe; and measuring the electrical spike potential generated between said probe and said first lead as an indication of the temperature of said hot member.
Claim 12
Independent Claim
77 words
A method of measuring temperature of a hot member of electrically conductive material, comprising the steps of: connecting a first lead to said hot member at a point remote from the point at which the temperature is to be measured; contacting said Hot member at the desired temperature measurement point with a probe; and measuring the electrical spike potential generated between said probe and said first lead as an indication of the temperature of said hot member.
