Customer scenario
An Algerian medical-device manufacturer scaling production of dynamic blood‑glucose test strips needed a fast, low‑risk way to validate reagent dispensing before committing valves to the production line. Key requirements were micro‑volume control to preserve costly enzyme reagents, uniform coating for consistent sensor response, a gentle fluid path to protect bioactivity, and a reliable prediction of production behavior to avoid costly rework during ramp‑up.
Challenge
On‑line qualification often reveals mismatches: nozzle geometry that creates irregular dots, pulse settings that cause satellite droplets, or pressure/temperature windows that change viscosity and flow. Discovering these issues after valve installation increases downtime, reagent waste and commissioning costs—critical problems when enzyme stability and material cost are primary concerns.
Mingseal FATP + KPS2000 solution
Mingseal supplied the FATP (Factory Acceptance Test Pack) built around the KPS2000 piezo jetting valve as a bench‑validation kit tailored to the Algerian customer’s enzyme reagent. The pack includes a KPS2000‑compatible valve, matched piezo actuator, three nozzle sizes, mounting flange and quick‑start guide—enabling practical, hands‑on qualification of droplet formation, repeatability and basic tuning before line installation.
Key technical fit
Sub‑nanoliter dosing and high frequency: KPS2000 supports jetting down to 0.5 nL and up to 1200 Hz, allowing the customer to test micro‑dosing recipes that reduce reagent use while maintaining sufficient film coverage for sensor chemistry.
Wide viscosity and chemical compatibility: The valve supports viscous fluids and resists common solvents, weak acids and bases, making it suitable for glucose assay formulations and stabilizers used in strip reagents.
Bench evaluation of nozzle options: The FATP includes three nozzle sizes so engineers can compare edge shape, dot spread and satellite formation on real substrate types used for the strips.
Controlled temperature and pressure windows: Using the pack, the team identifies stable pulse timing and pressure ranges at working temperatures (10–50°C) so on‑line settings are predictable and repeatable.
Process workflow used in validation
Fluid characterization: Teams run short tests on the bench to record droplet mass, spread and evaporation behavior for the enzyme formulation across the three nozzle sizes.
Pulse and pressure mapping: Operators sweep drive timing and supply pressure to find the narrow window that gives single‑drop formation without satellites at target throughput.
Thermal sensitivity checks: Small temperature shifts are applied to check viscosity sensitivity and to lock in the controller temperature window for production.
Wear and cleaning trials: Short continuous runs estimate nozzle fouling and define cleaning/purge schedules to preserve enzyme activity and minimize downtime.
Production outcomes and value
Microvolume control and cost containment: Bench‑proven sub‑nanoliter dispensing recipes reduced reagent consumption per strip and lowered per‑unit materials cost during scale‑up.
Uniform coating and accuracy: Validated nozzle/pulse combinations produced consistent dot geometry and film uniformity, tightening QC distribution and improving lot‑to‑lot sensor reproducibility.
Gentle fluid handling preserves bioactivity: Non‑contact piezo jetting with identified low‑shear pulse profiles minimized enzyme degradation compared with trial-and-error on‑line tuning.
Faster, lower‑risk commissioning: By resolving nozzle, pressure and temperature variables before installation, the customer shortened setup time, avoided rework and achieved stable production performance from first‑pass validation.
Conclusion
For Algerian makers of blood‑glucose test strips, the FATP test pack with the KPS2000 valve offers a pragmatic, low‑cost path to validate micro‑dispensing recipes, reduce reagent waste, and lock production parameters before line deployment. The bench kit ensures uniform, enzyme‑friendly coating and predictable integration—helping manufacturers meet accuracy, cost and reliability targets for clinical diagnostic strips.

Customer scenario
A leading Korean smartphone camera module supplier needed a robust inline solution for applying dust‑capture adhesive around infrared (IR) filter edges. The IR filter capture‑ring requires ultra‑clean, repeatable bead geometry to trap particulates without contaminating the optical path. The customer also wanted higher throughput: the line needed to support two distinct process steps (edge dust‑capture glue and protective seal) in parallel while maintaining sub-millimeter placement accuracy and strict process traceability.
Mingseal FS200A solution
Mingseal delivered the FS200A Inline Visual Dispensing Machine configured as a dual‑station, dual‑head cell to address both precision and throughput needs. The system’s dual independent valve architecture and separated track design enabled the customer to run two process stations concurrently—one head dedicated to the IR filter dust‑capture bead and the second to the protective seal—doubling effective UPH without increasing floor space.
Key process features and configuration
Dual independent dispensing heads: Two piezoelectric valves were installed—one tuned for ultra‑fine dust‑capture beads around the IR filter perimeter, the other for a slightly larger protective seal bead. Independent heads allow different adhesive chemistries and shot parameters to run simultaneously, minimizing cycle time and simplifying recipe management.
Dual‑station parallel workflow: The FS200A’s dual tracks and two processing stations enable true parallel processing: while Station A performs dust‑capture dispensing and inline inspection on one carrier, Station B simultaneously dispenses protective sealant on the next. This configuration effectively doubles throughput (UPH) compared with single‑station approaches.
Piezo valve tuning for demanding glue requirements: Piezoelectric jetting was selected to meet the customer’s low‑volume, high‑repeatability needs. Valve pulse shaping, back‑pressure control and nozzle selection were optimized to produce consistent droplet sizes and continuous bead profiles without stringing. The piezo valves support rapid metering for fast cycle times while maintaining sub-microliter dose precision required for IR filter edges.
Temperature‑controlled syringe feeding: To stabilize viscosity and avoid shot variation over long runs, the system implemented heated sleeves and syringe cartridges where required. Temperature control ensures predictable wetting and bead profile, crucial for optical cleanliness and adhesion reliability.
Integrated vision alignment and Smart AOI: High‑resolution vision alignment locates fiducials and precisely follows filter edges, ensuring bead placement stays within tight tolerances. Inline AOI verifies bead width, continuity and edge clearance immediately after dispensing; any out‑of‑tolerance events trigger automated rework or recipe adjustments.
Quality, traceability and uptime advantages
Separated track design for uninterrupted production: If one station requires maintenance or recipe change, the other track can continue processing, minimizing full‑line downtime and improving overall equipment effectiveness (OEE).
Recipe locking and MES integration: Dispense parameters, images and inspection logs are stored and exportable to MES/PLC systems for production traceability and failure analysis—supporting high-mix, high-volume requirements typical in Korean smartphone supply chains.
Yield and reliability improvements: Precise piezo dispensing combined with temperature stabilization and vision‑guided placement significantly reduced particle ingress risks and rework caused by misapplied beads. The result is improved first‑pass yield and reduced downstream defect escapes.
Conclusion
For Korean camera module manufacturers requiring meticulous adhesive control around IR filters, the FS200A provides a compact, dual‑station solution that combines piezo valve micro‑dosing, temperature‑stabilized syringe feeding, and high‑accuracy vision alignment. By supporting two concurrent process stations within a single footprint, the FS200A boosts UPH while ensuring optical cleanliness, placement repeatability, and full production traceability.
