QianLi LC-IRP01 Thermal/Visible Microscope For PCB Repair

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 of 160×120 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.

Using a normal/test board comparison analysis, the powerful intelligent PC analysis software supplied can quickly and accurately identify problem chips or short-circuits, which greatly speeds up fault detection, and improves operational efficiency and maintenance accuracy.  Finding short-circuits on a PCB can be very difficult by other means.  The PC software’s algorithms can detect and highlight thermal anomalies on a wide area – problems such as overheating motherboard chips or short circuits, which are hard to detect by other methods. By comparing normal and abnormal boards, it can help in quickly and accurately identifying circuit board faults.  The maximum value component temperature can be also correctly displayed.  The software provided can save images or video to preserve maintenance records, video evidence of faults, and provide dated reference comparisons for future maintenance or reports.

The QianLi LC-IRP01 Thermal Imaging Camera is available now from Saelig Company, Inc, starting from $995.
