MCA-3
The MCA-3, an image analysis contact angle meter, can accurately produce droplets as microscopic as 1×10-3to 10-5μL on extra fine patterns under 100μm wide which were impossible to measure by conventional contact angle meters.
Features
- High magnification lens and x12 zoom allows a field of view from about 75 x 56 μm to 900 x 670 μm.
- Available in 3 capillary inner diameters of 5μm, 30μm and 50μm.
- Special pneumatic dispensing system allows dispensing excellent volume of droplet.
- Included pixel calibration tool indicates the actual size of droplets.
- The vertical-mount camera provides a top view of the droplet. It enables pinpoint measurements of a micro-area, and allows observation of the wetting broadening behavior of the droplet.
- 60 fps camera captures the small volume droplets before they evaporate.The optional 1,000 fps high speed camera meets even quicker absorption requirements.
- Image data can be replayed as a movie (MPEG-1).
MCA-3 Explainer
Patterns on wafers and glass panels continue to grow smaller through technological development, demanding wettability measurements on increasingly tiny gaps in these patterns.
Since the evaporation or absorption of microscopic droplets into solid samples occurs rapidly, images must be continuously captured from the moment the droplet adheres to the surface. MCA-3 enables users to acquire accurate measurements with easy operation through the FAMAS measurement & analysis system.
Applications
- Measurement of gaps between microscopic patterns
- Measurement of thinner filaments like single fibers, hairs, etc.
- Pinpoint measurement in micro-areas like jet nozzles, electronics parts, etc.
- Observation of the wetting property of micro droplets to study differences from conventionally-sized droplets.
