System and method for measuring the thickness or temperature of a circuit in a printed circuit board

A system for measuring a thickness of circuit components on a printed circuit board (PCB), said system comprising:

• a first circuit;
• a power plane coupled to said first circuit powered by a power strip;
• a calibration strip having a predetermined width and being disposed in said PCB;
• a temperature regulator coupled to said PCB and configured to maintain said PCB at a set temperature;
• and
• a second circuit configured to determine the thickness of said calibration strip based on at least said set temperature of said calibration strip.

A method for determining a thickness of a power strip of a circuit on a printed circuit board (PCB), said method comprising the steps of:

• disposing a circuit onto a PCB;
• embedding a power strip having a first predetermined length and width into said PCB between a first power supply and said circuit;
• disposing a calibration strip having a second predetermined length and width into said PCB;
• providing a second power supply to said calibration strip and grounding said power strip to form a current flow through said power strip;
• measuring a first voltage across said power strip;
• measuring a second voltage across said calibration strip;
• determining a temperature of said PCB;
• and
• calculating a thickness of said power strip based on said first and second voltages, said temperature, said first predetermined length and width and said second predetermined length and width.
