Abstract:
1. A computerized method being executed by a processor of a computing device, the method comprising: (a1) receiving attribute parameters of a printed circuit board (PCB) from an input device, the attribute parameters comprising a layer type of a copper foil of the PCB, a thickness of the copper foil, a layout width of the copper foil for a component positioned on the PCB, and an amount of current passing through the component; (a2) generating, using the processor, a temperature rise formula according to the received attribute parameters of the PCB, wherein the temperature rise formula is I=a*S (a3) calculating, using the processor, a temperature rise of a local area of the PCB surrounding the component according to the generated temperature rise formula; and (a4) plotting a temperature rise distribution graph of the PCB on a display of the computing device when temperature rises of all components positioned on the PCB are calculated.
