Abstract: An instant monitoring system, applied to a circuit board, for inspecting an area under stress on the circuit board, comprises a strain gage, with a thin film structure, and at least one resistance, while the strain gage, with a first resistance value before receiving a stress, is embedded on the area, which receiving a stress, of the circuit board. The strain gage and the resistances, with the same first resistance value, connect electrically to form a Wheatstone bridge circuit.
