Circuit board temperature detection position selection, detection method, device, equipment and medium

Abstract

The embodiment of the invention relates to the technical field of electronic equipment manufacturing, and discloses a circuit board temperature detection position selection and detection method, device, equipment and medium. The method includes: evenly dividing the heating surface of the circuit board into several grid points; obtaining 1 simulation temperature data of M heating sources working under a preset power combination through simulation; S target grid points; if not, then repeat the simulation steps after increasing the number of grid points of the circuit board until S target grid points are obtained; obtain K parts of measured temperature data; combine K parts of measured temperature data with the corresponding simulated temperature The data is compared, and the Z target grid points whose temperature difference between the measured temperature value and the simulated temperature value meet the preset conditions are selected from the S target grid points; Z are removed from the S target grid points to obtain N target grid points Points, as N temperature detection positions of the circuit board; N is smaller than M. Therefore, the circuit board manufacturing cost can be saved on the basis of not affecting the temperature monitoring.

Description

technical field [0001] The invention relates to the technical field of electronic equipment manufacturing, in particular to a circuit board temperature detection position selection, detection method, device, equipment and medium. Background technique [0002] Compared with previous generation communication equipment such as 4G, the heat generated by 5G equipment has increased exponentially, so the temperature management of 5G equipment has become a research hotspot. At present, the temperature detection of the heat source on the circuit board is mainly to place a temperature detection circuit at each position where the temperature needs to be detected, such as an NTC (Negative Temperature Coefficient, negative temperature coefficient) sensor, etc., and each temperature detection circuit is connected to the main control The temperature detection port of the main control, such as the ADC port of the main control, etc., and then the main control reads the real-time temperature ...
