Taiwan mask Semiconductor   The PR-PD3 is a scanning machine used to detect small particles, primarily applied in the semiconductor manufacturing process for Particle Scan. Its function is to detect particle defects that may affect product quality during the manufacturing process, especially tiny contaminants. The machine uses the principles of Mie Scattering, polarized differential method, and low-pass filtering to accurately identify and screen particle defects. The PR-PD3 is a professional particle detection machine, typically used in semiconductor processes or other high-precision industrial applications. As it is a high-end device, its market price and second-hand value are influenced by several factors, including market demand, the condition of the equipment, and whether it includes warranty or additional accessories.
