Principle of Water Drop Angle and Surface Cleanliness Detection
Water droplet angle refers to the contact angle formed by water droplets on a solid surface, defined by the tangent angle between the gas-liquid and solid-liquid interfaces, and is a core parameter for evaluating surface cleanliness.Cleanliness measuring instrumentThrough high-precision droplet angle analysis (based on ADSA RealDrop) ® The Young Laplace equation fitting method of the algorithm quantifies the residual surface pollutants and energy state distribution, providing a basis for cleanliness grading for electronic components, optical glass, and other materials.
SL200L+surface cleanliness measuring instrument
Specially designed for industrial scenarios, it integrates a manual liquid inlet system and a large stroke sample stage (compatible with 300mm wafers), equipped with an industrial grade telecentric lens and quartz soft light source, and supports multi area scanning of surface cleanliness such as PCB and touch screen. CAST ® The 2.0 software has a built-in dynamic contact angle tracking module that can synchronize dynamically changing contact angles (with an accuracy of ± 0.2 °) and liquid-liquid interface tension, meeting cleanliness detection standards.
SL200L+professional droplet angle measuring instrumentModular system
Using precision optical mechanics and nanoscale titration technology (with a liquid control accuracy of 0.02 μ L), dynamic contact angle, surface free energy components (dispersion/polarity/hydrogen bonding force), and interfacial viscoelastic modulus were measured. The modular architecture supports the expansion of accessories such as high-pressure reaction tanks and vacuum environment chambers, and is suitable for harsh scenarios such as semiconductor pre packaging cleaning verification and medical implant biofilm detection.
