Where Is the Temperature of the PCB Highest?
Infrared thermal imaging technology can realize non-contact temperature measurement, and quickly find thermal defects of objects by imaging and analyzing the temperature distribution on the surface of the object.
Based on its advantages in temperature detection, infrared thermal imaging technology has been widely used in the temperature detection of various circuits and equipment such as PCB circuit boards, chips, LEDs, new energy batteries and energy saving, which significantly improves the efficiency of engineers.
Advantages of Thermal Imaging Technology
Non-contact non-destructive testing, more accurate temperature measurement;
Ultra-high infrared resolution, each thermal image contains 300,000 temperature data;
High-speed sampling, up to 30 frames per second;
Equipped with 20μm, 50μm and 100μm optional lenses;
Support full radiation thermal image video stream, video can be analyzed arbitrarily twice, and provide trend graph, 3D graph, numerical matrix, etc.
PCB circuit board design optimization
Circuit board temperature detection
Where does the circuit board get the highest temperature? Commonly used data acquisition and infrared temperature measuring guns have a limited number of measured temperature points and are difficult to find. Using the FOTRIC thermal imager to measure the temperature in full screen, you can visually observe the temperature distribution of the entire circuit board surface, and quickly find abnormal temperature points and devices.
Research on heat generation of circuit board
In addition, in the process of circuit research and development, it is necessary to monitor the temperature change trend of the entire circuit board. The picture is taken from the test video of the PFC inverter. The rectifier bridge is broken down during operation, causing the temperature of the DSP to rise, and the full radiation of the FOTRIC thermal imager. The thermal image video recording function records the temperature change and distribution during the power-on process in real time.
Micro-distribution detection of chips
Power chip temperature detection
The LED power chip in the picture is as small as 1mm*1mm. Since the chip is small, it is easy to change the temperature of the chip itself due to the contact measurement. Can a thermal imager measure temperature accurately? sure!
FOTRIC thermal imager is non-contact temperature measurement, supports 20μm macro lens, can directly perform micron-level micro-temperature imaging detection on small chips, find overheated connection lines and connection points, and improve chip design.
SMD fuse fuse test
The fuse process of the patch insurance is only about 300ms, which is difficult to capture by taking pictures.
The full radiation thermal image video recording function of the FOTRIC thermal imager can record the temperature change and distribution during the power-on process in real time, and can check the temperature rise curve at any time.
How to effectively analyze the collected temperature data?
We cooperate with the 3D temperature difference model (ΔT) of the AnalyzIR software for analysis, which can intuitively observe the abnormal heat distribution outside the design temperature or theoretical value, and provide various tools such as trend graph, 3D graph, numerical matrix, etc., which are helpful for the chip. design optimization.
Electronic product aging test
Board Aging Test
In the aging test of the circuit board, it is necessary to monitor the temperature of the product. The FOTRIC thermal imager can monitor the temperature of the product during the aging process in real time, and check the temperature change process to determine the performance of the product, which can also avoid the aging process. Fire caused by product failure.
FOTRIC scientific research series thermal imagers, with their excellent temperature measurement accuracy, have been generally recognized by the industry, and have now become the detection “artifact” of electronic engineers.
