Abstract:
An apparatus for measuring temperatures on at least a portion of a surface of an object for correlating measured temperatures with locations on said surface of said object, said apparatus comprising:a wire bonding machine having a bonding arm and an ultrasonic bonding generator controller; a sensor probe mount attached to said bonding arm of said wire bonding machine, said sensor probe mount including a plurality of members for a conductor mounted in a capillary holder attached to a portion of said bonding arm of said wire bonding machine; a decay temperature sensor probe having a conductor having a sensing tip located on one end thereof and having an opposite signal output end, said decay temperature sensor probe attached to one member of said plurality of members of said sensor probe mount attached to said bonding arm of said wire bonding machine; pulse generating apparatus connected to said opposite signal output end of said decay temperature sensor probe to generate a pulse through said conductor to material at said sensing tip and to receive from said opposite signal output end a signal representative of a temperature at said sensing tip; an electronic trigger circuit connected to said wire bonding machine for initiating the generation of said pulse, said electronic trigger circuit initiating a signal for a temperature measurement upon receiving a voltage signal comprising an output signal of said ultrasonic bonding generator controller of said wire bonding machine; thermometer apparatus for calculating a temperature indication from said signal representative of a temperature at said sensing tip; stage apparatus attached to a portion of said wire bonding machine for mounting said object thereon; control apparatus for manipulating a position of said stage apparatus relative to said sensing tip; and computing apparatus having software for receiving said temperature indication and correlating and storing said temperature indication in machine-readable form as a function of one of time and location on said at least a portion of said surface of said object.
