How to Choose Thermal Imaging Camera for Mobile Phone Repair?
In the realm of mobile phone repair, a thermal imaging camera serves as an indispensable tool, acting as the "X-ray vision" for repair technicians to swiftly pinpoint fault locations. Yet, with the diverse range of thermal imaging cameras flooding the market, how does one select the ideal device tailored for mobile phone repair? Core technical parameters: the cornerstone of accurate detection Resolution and thermal sensitivity Resolution (e.g. 256×192, 320×240): Higher resolution (e.g. 320×240) enables clearer thermal images, which is essential for identifying hot spots on tiny mobile phone components such as IC chips or capacitors. For example, a resolution of 320×240 can distinguish temperature differences on components as small as 0.1mm². Thermal sensitivity (NETD): Lower NETD (e.g. <50mK) means higher sensitivity to subtle temperature changes. Mobile phone chips typically produce a temperature difference of 2 to 5°C during failure, so a thermal imager with NETD<50...
