Changzhou Mingseal Robot Technology Co., Ltd.

Customer scenario A Vietnamese laptop manufacturer needed a reliable inline solution to coat, encapsulate and protect chips mounted on flexible printed circuits (FPCs) used in notebook hinge and connector assemblies. Production demand targeted 100,000 coated FPC assemblies per 24‑hour shift, with processes requiring low‑temperature thermosetting hot‑melt adhesives to avoid heat damage to flexible substrates and nearby components. Key challenges were maintaining consistent bead mass and coverage during high-speed runs, preventing stringing and overflow that can affect connector contacts, and providing traceable process control for quality and yield. Mingseal FS600DDF solution Mingseal recommended the FS600DDF Visual Inline Dispensing Machine configured for high-volume low‑temp hot‑melt coating and protective filling on FPC chip areas. The FS600DDF’s heated syringe cartridge system, fast‑response valve options (piezo/VCM), high‑precision gantry motion, optional weighing and 2D/3D vision combine to meet throughput, process stability and traceability targets. Process highlights and implementation Low‑temperature thermoset adhesive control: The FS600DDF supports heated syringe cartridges and heated lines with closed‑loop temperature control to maintain adhesive viscosity within narrow windows suitable for low‑temp thermosets. Temperature stability prevents premature gelation and ensures controlled wetting on FPC copper pads and polymer layers. Fast, responsive valves for clean deposits: For micro‑dot and fine bead work, a piezo valve option delivers sub‑nanoliter to nanoliter control and minimizes stringing during rapid strokes. For larger protective fills, a VCM valve offers repeatable volumetric flow. Valve pulse profiles and nozzle geometry were tuned to eliminate tailing and ensure clean, isolated deposits near delicate contacts. High‑precision motion and vision alignment: With repeatability of ±10 μm and pixel resolution ≤8 μm/pixel, the FS600DDF’s vision system performs fiducial and feature alignment at line speed. Fly‑align capability preserves placement accuracy during high‑throughput double‑track operation, critical for the small chip footprints on FPCs. Dual‑track operation to meet UPH: The FS600DDF’s optional double‑track configuration and auto width adjustment allow two parallel production lanes on a single platform. Coupled with high motion speed (X/Y up to 1300 mm/s) and fast valve actuation, the system achieves the required throughput of 100,000 units per 24 hours while keeping machine footprint and staffing minimal.Inline verification and recipe traceability: Optional microbalance weighing (0.01 mg) and real‑time vision inspection verify deposited mass and wet bead geometry. Dispense recipes, temperature logs and inspection images are logged to MES/SECS‑GEM for full traceability and process control. Production outcomes and value Achieved throughput: By deploying dual tracks, synchronized dual valves and optimized dispense paths, the FS600DDF met the 100k/24h production target without sacrificing deposit quality. Consistent protective coverage: Closed‑loop temperature control and valve tuning reduced shot‑to‑shot variance, preventing under‑ or over‑apply that can lead to connector failures or assembly rework. Reduced defects and rework: Vision‑guided placement and inline weighing cut misplacement and volume variance, decreasing downstream solder or mechanical failures and improving first‑pass yield. Lower thermal risk to FPCs: Low‑temperature thermoset handling preserved substrate integrity and component reliability, reducing warpage and delamination risks common with higher‑temperature processes. Operational resilience: The FS600DDF’s modular design and MES connectivity support quick recipe changeover between different FPC designs and adhesives, and isolated track operation minimizes downtime during service. Conclusion For Vietnamese laptop OEMs facing high‑volume FPC chip coating and protective filling requirements, the FS600DDF provides a proven inline solution. Combining low‑temp hot‑melt handling, fast metering valves, micron‑level motion control, dual‑track throughput and inline verification, the FS600DDF secures consistent protection, higher yields and the production rate needed for modern notebook assembly lines.

Customer scenario A South Korean smartphone camera module manufacturer needed a compact, high-throughput solution to apply dust‑capture adhesive to infrared (IR) filters used in front‑camera assemblies. The customer required simultaneous handling of two process steps on a single platform—reinforcement (structural support) and UV/thermal cure application—without increasing footprint. Challenges included fine-line dispensing inside tight optical cavities, consistent adhesive volume for optical performance, and a desire to raise UPH by running two stations in parallel while keeping maintenance and changeover simple. Solution overview — Mingseal FS200A dual‑head inline dispenser Mingseal deployed the FS200A configured as a dual‑station, dual‑head inline dispensing machine tailored for IR filter dust‑capture adhesive (catch‑and‑hold) and reinforcement/curing operations. The system’s combination of precision motion, syringe cartridge feed with heated sleeve options, piezo valve capability and integrated vision alignment addressed the customer’s demands for speed, accuracy and process flexibility. Key process features Dual independent stations (one machine, two processes): The FS200A’s separated track and dual‑valve architecture allow simultaneous operation of two workstations. One head performs micro‑dot and bead patterns for dust‑capture adhesive around the IR filter edges; the second head applies reinforcement adhesive or a thin pre‑coat designed for later curing and structural bonding. Running both stations in parallel increased UPH without adding additional hardware. Piezo valve adaptability: For micro‑volume, non‑contact dotting, a piezo valve option delivered droplet control down to sub‑nanoliter to nanoliter regimes suitable for narrow optical gaps. Valve pulse tuning minimized stringing and ensured consistent dot geometry during high‑speed operation. For thicker reinforcement adhesive, the second valve option used rapid valve/pump metering to deposit controlled beads with repeatable mass. Precision motion and vision alignment: High‑resolution motion control (≤±10 μm repeatability) combined with integrated cameras enabled fiducial and feature alignment across the 330 × 205 mm work envelope. Fly‑align at production speeds preserved placement accuracy when switching between single and dual‑track modes. Syringe heating and rheology control: Optional heated sleeves and full recipe control preserved adhesive viscosity for consistent flow and wetting. Temperature setpoints were locked per recipe to prevent over‑ or under‑apply that could affect optical clarity or curing behavior. One‑machine two‑use flexibility and easy changeover: The FS200A’s recipe storage and MES/PLC interfaces allowed quick switching between product families (different IR filter sizes or adhesive chemistries). The isolated track design meant one station could be serviced while the other continued production, minimizing line downtime. Production results and benefits UPH improvement: Running dual stations in parallel increased effective throughput by up to ~80% for dust‑capture + reinforcement cycles compared to a single‑station workflow, substantially raising line capacity without expanding floor space. Better optical and functional yield: Consistent micro‑dot volume and precise placement reduced particle entrapment and adhesive overflow, lowering rework rates and improving camera image quality and autofocus performance. Robust curing and mechanical protection: Controlled reinforcement deposits ensured reliable cure and mechanical stability during subsequent assembly steps, protecting delicate IR filter edges and improving long‑term durability. Lower maintenance impact: The separated track design and independent valve systems reduced full‑line stoppages; piezo valve tuning and syringe heating minimized stringing and clogging, lowering consumable waste and maintenance frequency. Conclusion For Korean smartphone camera manufacturers requiring high‑precision dust‑capture adhesive application on IR filters, the FS200A delivers a compact, dual‑use inline solution that raises UPH and product quality. By combining piezo and fast‑meter valves, heated syringe control, vision‑guided placement and a dual‑station layout, Mingseal’s FS200A secures consistent optical performance, faster throughput and lower downtime—supporting scalable production for advanced mobile camera assemblies.
