The QianLi’s 160×120 thermal imaging sensor and 1920×1080 visible sensor combine to make a powerful circuit board repair tool, especially helpful in finding overheating or short-circuit issues.
Saelig Co. Inc. has introduced the QianLi LC-IRP01 Thermal Imaging Camera, a diagnostic tool for PCBs which displays heat images to help identify damaged or malfunctioning components or short-circuits. The QianLi LC-IRP01 Thermal Microscope contains two imagers, one for visible wavelengths and one for infrared heat images. These images can be combined on a PC display to quickly identify problem areas. Searching for missing, incorrect or charred components, bad solder joints, and solder bridges becomes much easier with this powerful thermal microscope.
The QianLi Thermal Imaging Camera consists of three parts: the detection head with both an infrared camera and a visible wavelength camera, an adjustable stand, and the powerful computer analysis software. This thermal detection device can display a visible light image, an infrared thermal image, or a visible/infrared superimposed image. This unique combination quickly shows the location of suspect chips or short circuits by switching between both images via the keyboard’s space bar.
Visual inspection with the QianLi’s 1920×1080 sensor is a valuable tool in PCB debug activities, but the addition of160×120 thermal imaging is especially helpful in finding overheating issues. Rather than using a thermocouple to find the temperature of an individual component, the QianLi displays all of the board temperatures at once. Looking for solder whiskers or bridges between pads or solder joints is especially challenging between the pins of fine-pitch SMD chips without significant magnification, and this device offers 800x digital zooming. If the problem is a short circuit, it will be plainly visible on the PC as an anomalous heat spot when power is briefly applied.
