Problems solved by technology
[0005] If the detection process misjudges that the heat dissipation mechanism of the processor is not normal, engineers still need to reopen the electronic device and check the attachment status of the thermal pad. This process is quite unnecessary and time-consuming, and will seriously affect the overall detection efficiency.

The invention discloses a method for detecting a heat dissipation unit and a detecting system of the heat dissipation unit. The method comprises the steps of (1) setting a preset temperature difference value, (2) setting the work cycle of a processor as a first work cycle value, (3) detecting the temperature of the processor under the first work cycle value, (4) setting the work cycle of the processor to be a second work cycle value instead of the first work cycle value, (5) detecting the temperature of the processor under the second work cycle value, (6) calculating the temperature difference of the processor between the first work cycle value and the second work cycle value, (7) comparing the temperature difference with the preset temperature difference value to generate a record value, (8) repeating the steps (2) to step (7) and adding up the record values, and (9) judging whether the heat dissipation unit is normal according to the accumulated record values. According to the method for detecting the heat dissipation unit and the detecting system of the heat dissipation unit, whether the heat dissipation unit is normal can be judged by repeatedly detecting the temperature difference of the processor between different work cycle values, and then testing time is shortened and the testing error possibly caused by environment variation can be reduced.
Description
【Technical field】 [0001] The invention relates to a technology for detecting electronic devices, in particular to a method for detecting a heat dissipation unit and a detection system for the heat dissipation unit. 【Background technique】 [0002] In order to make the processor of the electronic device operate normally, it is necessary to make the processor run at an appropriate operating temperature, so as to prevent the processor from being overheated and affecting the operating performance. In order to prevent the processor from overheating, a heat conduction sheet is attached to the processor to accelerate heat dissipation of the processor. [0003] However, if the heat conduction sheet is not completely attached to the processor (for example, it is crookedly attached, or the heat conduction sheet only partially covers the processor), the heat dissipation effect of the processor will be greatly reduced. Therefore, after the installation process is completed, the manufact...
