Overview
IEC 60747-18-3:2019 - "Semiconductor devices - Part 18-3: Semiconductor bio sensors - Fluid flow characteristics of lens-free CMOS photonic array sensor package modules with fluidic system" - defines standardized methods for characterizing fluid flow in lens-free CMOS photonic array sensor package modules used for bio analysis. The standard specifies the measurement setup, initial-state and steady-state flow measurement and calculation methods, criteria for quality assurance, calibration procedures, and the required content of the test report.
Key topics and technical requirements
- Measurement setup and system requirements
- Defined measurement configuration for lens-free CMOS photonic array sensors integrated with a fluidic system, including photoelectric measurement schematics and sensor parameters.
- Initial-state flow measurement and calculation
- Procedures to capture and analyze flow propagation profiles during early, intermediate and final stages of flow introduction.
- Methods to calculate horizontal and vertical flow velocities for both global shutter and rolling shutter sensor readout modes.
- Steady-state flow analysis
- Measurement and calculation methods covering all pixels at every frame to assess uniformity and stability of the fluidic environment over time.
- Calibration and planarization
- Calibration procedures to correct non-uniformities in the fluidic system and sensor response, including final evaluation of calibrated modules.
- Quality assurance criteria
- Defined pass/fail criteria and statistical evaluation approaches (e.g., per-column and full-frame analysis) to ensure reproducible fluidic performance.
- Test reporting
- Required contents for a test report documenting setup, measurement parameters, calculations, calibration, and evaluation results.
- Terminology and fluid dynamics context
- Includes relevant definitions such as Reynolds number and linearity for accurate interpretation of flow behavior.
Practical applications and who uses this standard
IEC 60747-18-3 is directly applicable to:
- Semiconductor and sensor manufacturers developing lens-free CMOS photonic array sensor modules with integrated microfluidics.
- Medical device and diagnostics companies using lens-free sensors for point-of-care, patchable, implantable, or lab-on-chip bio-analytical devices.
- Test laboratories and QA teams validating fluidic performance, repeatability, and conformance to product specifications.
- R&D teams optimizing fluid delivery, sensor calibration, and imaging protocols in lens-free microscopes and biosensing platforms.
Practical uses include characterizing flow propagation in porous media, verifying uniform sample delivery for bioassays, and ensuring sensor-module reliability in healthcare and diagnostic products.
