Circuitry testing method and circuitry testing device
First Claim
1. A circuitry testing method, comprising:
- providing a circuit board needing testing;
applying a potential to the circuit board needing testing so that the circuit board works and operating elements of the circuit board needing testing emit infrared rays;
testing an intensity of radiation of the infrared rays using an infrared sensor;
converting the radiation intensity to RGB (red, green, blue) data signals in order to form a diagnostic infrared image, using a processor;
providing a standard infrared image;
comparing the diagnostic infrared image with the standard infrared image; and
determining whether the circuit board is defective according to the comparison;
wherein if the diagnostic infrared image is the same as the standard infrared image, the circuit board is determined to have no defect ;
andif the diagnostic infrared image is different from the standard infrared image, the circuit board is determined to have at least one defect in at least one area thereof corresponding to at least one difference between the diagnostic infrared image and the standard infrared image.
