Fast technology of PCBA circuit board failure analysis and failure detection
We provide this kind of thermal imaging circuit board failure test, the circuit board failure detector is specially designed for the failure analysis of circuit boards and electronic devices. Using infrared imaging technology, it can quickly detect the location of the defect, thereby reducing the detection time and Cost, but also reduce the generation of waste. In addition, this set of circuit board PCBA failure analysis instruments, PCBA failure detection instruments can also detect the basic functions of circuit boards. Compared with the traditional professional circuit board detection methods, this set of PCBA failure test instruments, PCBA failure test instruments The price is lower, PCBA short circuit tester, PCBA bad analyzer are more convenient to use, and the effect is more intuitive. PCBA defect tester, PCB defect tester, PCBA short circuit tester can be widely used for power supply to ground short circuit repair, inner layer short circuit repair, BGA short circuit repair, transistor short circuit repair, diode short circuit repair, inductor short circuit repair, decoupling capacitor short circuit repair Maintenance, internal short circuit of electronic components, resistance short circuit, bad die check, circuit board maintenance, printed circuit board, failure analysis, infrared imaging, thermal imaging maintenance, circuit board short circuit inspection.

For this kind of short circuit problem, we use a high-sensitivity thermal imaging camera, combined with powerful noise reduction and image enhancement processing software, to provide you with a tool to quickly determine the location of the problem, which can identify the problem in a few seconds. It can detect anomalies as small as 1 milliwatt of power consumption, and can detect an increase in temperature of 0.03 degrees Celsius.

In the test process, the circuit board can be powered on for 5-10 seconds to start the inspection work. The I/0 module we are equipped with can automatically control the power input into the circuit board. After the circuit board is powered on, the short-circuit part will dissipate heat. This set of PCBA failure analysis, PCBA failure detection, and PCB failure analyzer will easily capture the temperature rise to find the location of the short circuit. A short circuit with high resistance (greater than 10 ohms) causes a temperature rise of at least 1 degree Celsius, which is not difficult to detect. However, for a low-resistance short circuit, such as 0.5 ohm, the temperature rise caused is very weak, perhaps only 0.2 degrees Celsius, and it is very difficult to detect such a short circuit. But our printed circuit board failure analyzer and printed circuit board failure finder have the function of "noise deduction and image enhancement" in the software. When the detection system is working in this mode, when the circuit board is not powered on, the system will collect a A thermal image is used as a reference. After the circuit board is powered on, a series of thermal images of the circuit board will be collected. These images will be subtracted from the "reference image" through image processing, so that a very weak temperature change after the circuit board is powered on can be obtained, even for With a temperature change of 0.03 degrees Celsius, this printed circuit board short circuit detector and printed circuit board short circuit locator can find the location of the short circuit. Low resistance and grounding defects are found in the test. Use the software's transparent image overlay function software to help you detect defects with resistance as low as 1 ohm. Small resistance traps are the only place where thermal problems exist. Quickly find the defect location and consume less power. A series of measurement results can be averaged to obtain higher sensitivity measurement results. The software can also automatically cut off the power to the circuit board, thereby protecting the PCB board from damage.
