ActiveDetection method of degree of sphericity of spherical silica for electronic packaging—Particle dynamic photoelectric projection method
电子封装用球形二氧化硅微粉球形度的检测方法 颗粒动态光电投影法
Application Summary AI generated
This standard specifies a detection method using particle dynamic photoelectric projection to measure the sphericity of spherical silica powders used in electronic packaging. It is applied in the quality control and testing of silica fillers for epoxy molding compounds and underfill materials in semiconductor packaging. The method ensures consistent particle shape, which is critical for achieving uniform thermal expansion and flow properties in high-density integrated circuit encapsulation.
