Features: Wide applications: This tool can be used for small current leakage quick positioning, heat dissipation analysis of PCBA, short circuit location positioning, compoent failure inspection, comparative analysis, quality control, integrated circuit transient temperature change, observation of battery temperature rise. The PCBA placed on both sides of the dividing line,and the comparative analysis is carried out under the same conditions. Multiple modes of software corresponding to different application scenarios, such as temperature distribution line, regional inspection, 3D thermal field, multiple color palette. The focal length is adjustable for clear images, different distances will leads to unclear images, the definition of the images is controlled by adjusting the focal length of the camera. With the complete temperature data curve record and detailed temperature data comparison, over limit temperature can be automatically photographed.
