Abstract
A first strip and a second strip of metal are embedded on a first layer of a printed circuit board (PCB) to form a junction. The junction has a first strip tail and a second strip tail. The first strip and the second strip are made of different metals. A first trace and a second trace are fabricated on a second layer to extend the junction to a first trace pad and a second trace pad, respectively. The first and second traces are fabricated on a second layer. The first and second traces have a first end one and a second end one, respectively. The first end one is connected to the first strip using a first via and the second end one is connected to the second strip using a second via. A first wire is inserted to the first via and a second wire to the second via to measure the temperature of the PCB.
