[Image][Image]Spectroscopy records the intensity variations of light at different wavelengths, revealing the interaction between matter and light, which serves as the “optical key” for analyzing composition, structure, and properties. However, traditional spectral measurements are limited by the long-standing inherent contradiction between spectral resolution and imaging flux in spectroscopic acquisition and solidified structural measurements, which has … Read more
3D printing can transform a “virtual model” into a “physical object,” and composite resins are the key materials in this “magic.” From general-purpose to specialized functional types, different kinds of 3D printing composite resins allow various creative ideas to come to life easily. Want to print everyday small ornaments? General-purpose light-curing 3D printing composite resins … Read more
In the PCB (Printed Circuit Board) manufacturing process, the issue of “adhesive residue” is like an inescapable ghost, permeating multiple key processes from inner layer lamination to final electroplating, circuit, and solder mask. It not only directly affects the appearance of the product but also leads to fatal defects such as copper sinking blockage, electroplating … Read more
