Troubleshooting PCBs is a complex task, but thermal imaging cameras are becoming increasingly affordable and are now widely used in electronics and cell phone repairs. In this guide, we’ll explore the five best thermal imaging cameras for PCB inspection and cell phone repair.
Thermal imaging technology plays an important role in the inspection of electronic devices, working by capturing the invisible infrared radiation (heat) emitted by objects. The effectiveness of this technology lies in its ability to quickly identify abnormal hotspot areas created on the circuit board. There are several significant advantages to using an infrared thermal imaging camera for PCB inspection:
1, it can quickly find problem points of overheating, which helps to quickly solve faults in complex circuits;
2, non-contact temperature measurement eliminates direct contact A circuit board is not required, thus reducing the risk of short circuit or electric shock.
When choosing a thermal imaging camera, there are several key factors to consider to ensure its accuracy and usefulness. First, the resolution of the sensor determines the clarity of the image. High-resolution sensors produce images with greater detail and are especially useful for small objects that require precise measurement. Secondly, the accuracy and sensitivity of temperature measurement are important basis for selecting a thermal imaging camera. Professional-grade cameras can be accurate to a tiny temperature difference of 0.06°C, while budget cameras may offer high sensitivity around 0.15°C. There are also differences to consider between handheld and desktop cameras – if you need a device that’s lightweight and suitable for mobile operation, a handheld thermal imaging camera is ideal. However, for situations where extended use is required in a laboratory environment, desktop thermal imaging cameras are more suitable due to their hands-free use and ergonomic design.
Now, let’s take a closer look at four thermal imaging cameras designed specifically for PCB inspection and cell phone repair.
