Overview The GS700SU is a high-speed, high-precision dispensing system purpose-built for large-package FCBGA underfill. Designed to meet the thermal and structural demands of AI and high-performance computing (HPC) modules, the GS700SU delivers robust throughput, full inspection and production-grade process control in large-format underfill applications. Customer challenge A Texas manufacturer producing large FCBGA modules required a reliable, automated underfill cell that supports larger package footprints and board boats while maintaining void‑free capillary underfill and traceable process control. The line needed to integrate into cleanroom flow, support multiple track configurations for high UPH, and provide full inspection to protect the high value of finished modules used in AI/HPC systems. Mingseal GS700SU solution The GS700SU was deployed for large‑package FCBGA bottom fill. Key configuration and process capabilities delivered to the Texas customer include: Large boat & flexible track support: The system accepts maximum boat sizes up to 325 × 325 mm in a dual‑track / four‑workstation / dual‑head layout, and supports 325 × 162 mm boats with a four‑track / eight‑workstation / dual‑head configuration. This flexibility allows the customer to process large panels or split workloads for mixed production. Multi‑head, multi‑track throughput: Dual independent dispensing valves combined with a four‑track architecture enable high units‑per‑hour performance. Compared with earlier systems, the GS700SU increases effective throughput by up to 3.7×, matching factory Q‑TIME and high‑mix production demands. Underfill‑specialized dispensing: Proprietary underfill valves, tilt dispensing modules and programmable dispensing patterns support tight KOZ requirements (KOZ < 200 μm) and controlled capillary flow across tall bump geometries. The GS700SU minimizes void formation while ensuring consistent wetting under large die sizes. Full inspection and process control: An independent AOI station, high‑accuracy laser height sensing (±1 μm) and electronic weighing (0.01 mg) verify glue placement, dot mass and complete coverage. Automated glue weight adjustment, nozzle glue detection and unit dispensing trials reduce variance and improve first‑pass yield. Thermal and material management: Multi‑zone temperature control with ±1.5°C heating uniformity maintains adhesive rheology during long production runs. Intelligent sequencing of product handling and glue replenishment reduces the risk of overflow or insufficient flow in large package fills. Performance and production value High stability and yield: Tight process control and inline inspection deliver consistent underfill coverage for PKG >50 × 50 mm, lowering rework and improving downstream reliability for AI/HPC modules. Significant throughput gains: The multi‑track, dual‑head architecture enables up to 3.7× higher effective throughput versus earlier generation systems, reducing capital footprint per unit output. Compatibility with advanced designs: KOZ < 200 μm capability and minimum nozzle diameters down to 30 μm support dense passive placements and modern large die layouts. Traceability and integration: GS700SU supports semiconductor communication protocols and MES integration for full traceability of recipes, images and weight logs—critical for audit and quality control in high‑value packaging. Conclusion  For Texas-based AI/HPC module manufacturers working with large FCBGA packages, the GS700SU provides a proven underfill dispensing solution that combines high UPH, fine process capability and comprehensive inline inspection. By supporting large boat sizes, multi‑track throughput and underfill‑specific dispensing strategies, the GS700SU secures void‑free, repeatable underfill performance—reducing risk, raising yield and accelerating time to volume.

Customer challenge A Vietnamese manufacturer in the A‑system VCM (Vacuum Coating Material/Magnetic tape) sector needed to scale smart production for volatile demand while improving yield and reducing downtime. The customer required a turnkey, automated line that delivered high throughput, precise micro-dispensing, and robust inline inspection to meet strict quality and traceability targets. Mingseal’s FI100 was adapted to this VCM application and has already been delivered in volume—15 production lines deployed for A‑system VCM clients. Mingseal solution: FI100 smart LiDAR‑derived line adapted for VCM production Leveraging the FI100’s proven automation architecture, Mingseal configured a VCM smart production line that integrates synchronized dual‑valve dispensing, dual‑track transfer, closed‑loop metrology, and intelligent handling to meet the customer’s cycle time and yield targets. Key process adaptations and technology highlights Dual‑valve synchronized compensation: Two piezo/servo dispensing valves operate in perfect sync to compensate for valve drift, maintain dot uniformity and enable faster, balanced deposition across wide substrates. Synchronized operation reduces per‑station cycle time while preserving micro-dispense accuracy critical to VCM coating processes. Dual‑track conveyor system: A two‑rail transfer layout replaces conventional single-line conveyance, enabling parallel processing and buffer handling between stations. This architecture increases operational throughput by roughly 70% versus standard linear conveyors and supports high availability for continuous production. Micro‑glue automatic correction system: Inline timed weighing stations perform scheduled microbalance checks and automatically recalibrate valve parameters. The self‑correcting loop reduces manual intervention and shortens maintenance stops—saving approximately 1.5 hours of downtime per day and boosting daily capacity by about 4,500 units. Station consolidation and stationary processing: Following the FI100 philosophy, assembly, dispensing and curing steps are performed with the product held stationary under the robot to avoid repeated clamping. This reduces handling errors and preserves coating uniformity across sensitive VCM substrates. Dual‑vision guidance and AOI closed loop: Dual high‑resolution cameras provide simultaneous alignment on both sides of the product for precise dispense placement. Each station features AOI (Automated Optical Inspection) to monitor process quality in real time, enabling corrective action before defects propagate downline. Comprehensive sensor monitoring: Laser height sensing, pressure monitoring and torque feedback are integrated to supervise assembly, dispense volumes and cure profiles. Full data logging enables MES integration for traceability and predictive maintenance. Production results and customer value Significant throughput improvement: The dual‑track and dual‑valve architecture increases operational efficiency by approximately 70% compared with legacy single‑line setups, enabling faster takt and higher output per footprint. High yield and consistent quality: Process control and closed‑loop correction drive a demonstrated first‑pass good rate above 99.5%, reducing scrap and rework costs in mass production. Reduced downtime and higher daily capacity: Automated micro‑glue calibration cuts roughly 1.5 hours of daily stoppage, translating to an additional ~4,500 units of daily output for the customer’s VCM lines. Improved process stability and traceability: Stationary processing, AOI feedback and MES logging provide robust process stability, easier qualification across lots, and comprehensive traceability for audits. Conclusion For Vietnamese A‑system VCM manufacturers, the adapted FI100 smart production line delivers a scalable, high‑yield solution combining dual‑valve compensation, dual‑track transfer and automated micro‑glue correction. With 15 lines already delivered in the A‑system VCM field, the FI100 demonstrates proven performance—boosting throughput, reducing downtime, and securing consistent product quality at scale.

Customer challenge A Malaysian semiconductor contract manufacturer preparing to volume-produce FCBGA CPU modules needed a domestic, production-ready underfill solution that met strict keep-out zone (KOZ), flow-height and traceability requirements. Substrates up to 325 × 162 mm carried high-density CPU dice where uncontrolled capillary flow or overflow could cause electrical shorts, thermal issues and yield loss. The customer required a system that combined repeatable micron-level dispensing, robust material monitoring and stable thermal control for long production runs. Mingseal solution: GS600SUA — China’s first domestically produced mass-production FCBGA underfill dispenser Mingseal deployed the GS600SUA tailored for FCBGA bottom-fill (capillary underfill) on 325 × 162 mm boats. The GS600SUA integrates precision piezo jetting, active flow-height management, visual alignment and multi-layer material protection to meet the customer’s yield and reliability targets.
