Meaning
Metrology process used to verify the precise geometry of internal channels and ports within a fluid-handling component. Micro-fluidic manifold dimensional inspection ensures that the paths for liquids are free of obstructions and meet the required diameter for controlled flow. It uses non-destructive methods to see inside the opaque or complex structures.
Channel Geometry
Geometry of the internal voids is critical for the performance of the device in medical or chemical applications. Small variations in the cross-sectional area can cause pressure drops or turbulent flow that ruins the sensitivity of the analysis. CT scanning is often the only way to measure these features without cutting the part open.
Tolerance Verification
Verification of the physical dimensions is performed against the original CAD model. The software compares millions of data points from the scan to the theoretical design to find deviations. This comparison identifies if the manufacturing process, such as injection molding or 3D printing, is producing parts within the allowed margin of error.
Yield Stability
Stability of the production yield depends on catching drift in the dimensions before it leads to failed parts. Regular inspections help the manufacturer adjust their settings and maintain a high rate of production. The inspection results are used to qualify the supplier and the manufacturing process for high-volume output.
