Choosing measurement points for the temperature board should follow the principles below based on the complexity of the PCBA: 1. For one measurement point, select the BGA solder ball on the PCBA; 2. For two measurement points, select the “pins + pads” of the IC components on the PCBA; 3. For three measurement points, select … Read more
The commonly used simple status monitoring methods mainly include auscultation, touch, and observation. 1. Auscultation When the equipment is operating normally, the accompanying sounds always have a certain melody and rhythm. As long as one is familiar with and masters these normal melodies and rhythms, abnormal noises that are heavy, mixed, strange, or chaotic can … Read more
Infrared Thermometer Technical Principles All objects with temperatures above zero degrees (-273.15°C) continuously emit infrared energy into the surrounding space. Their radiation characteristics, the magnitude of radiation energy, wavelength distribution, etc., are closely related to the object’s surface temperature. Conversely, by measuring the infrared energy emitted by the object itself, we can accurately determine its … Read more
