The inductor uses 3D to detect the coplanar degree of its welding feet. The core reason lies in its unique physical structure and key role in the circuit, which requires extremely high mechanical strength and electrical reliability of welding. Different from ordinary resistances and capacitors, inductors are usually large in volume and heavy in quality, and may be accompanied by vibration or heat generation during operation. All these factors pose severe challenges to the reliability of its solder joints. Sanrui Vision 3D detection technology can obtain the three-dimensional profile and height information of welding feet, and can clearly judge the coplanar degree, warping condition and the climbing height of soldering tin of each pin, the comprehensive evaluation of welding quality is realized, thus ensuring the long-term stable operation of the final electronic products.
