Advanced Underfill Dispensing Solution for CUF Application in FCBGA FCCSP SiP

The GS600 series Automatic Underfill Dispensing Machine is an industry-grade solution engineered for high-precision CUF (Capillary Underfill) dispensing tasks in advanced semiconductor packaging, including FCBGA, FCCSP, and SiP modules. The GS600 series combines a piezoelectric jetting valve with six integrated process modules, which ensures steady flow rates and consistent glue patterns, even with high-viscosity epoxy and underfill adhesives. Automatic platform loading and unloading modules, plus inline visual inspection, complete the fully automated workflow, keeping yields high and manual intervention minimal.

Core Advantages

• Exceptional underfill accuracy: Piezoelectric CUF jetting module with micro-gram precision.
• Consistent quality: Closed-loop glue temperature management maintains stable flow.
• No downtime surprises: Triple low-level detection ensures glue supply stays continuous.
• Controlled heating: Vacuum fixture plus real-time heat feedback guarantees uniform substrate preheat.
• Automated operation: Fully automated wafer or substrate loading/unloading with integrated visual inspection to detect flaws before or after the process.
• Dual-track press-down structure: Preserves workpiece flatness for perfect underfill gap control.

FAQ

Q1: What type of adhesives are compatible with the GS600 series?
A: The machine supports a wide range of underfill epoxies, high-viscosity adhesives (up to 200,000cps), and other advanced formulations needed for fine-pitch semiconductor applications.

Q2: How does it keep the glue temperature consistent?
A: The CUF piezo jetting system works with a real-time closed-loop heater that keeps fluid-box and nozzle temperatures stable within ±2°C.

Q3: What if the glue runs low during operation?
A: The GS600 series uses triple-level alarms — weighing, capacitive sensing, and magnetic detection — to alert operators before glue runs out, avoiding process interruptions.

Q4: Can the GS600 series be integrated into an existing line?
A: Yes! The unit’s modular loading/unloading and SMEMA-compatible track design make integration into advanced packaging lines quick and cost-efficient.
