Overview
The YAMATO YYK500/750/800/900 series are precision-engineered pressurized deaeration chambers designed for critical bubble elimination in flat-panel display (FPD) manufacturing—particularly after polarizer lamination onto LCD substrates. Unlike vacuum-based systems, these units operate on a controlled positive-pressure principle: compressed, oil-free dry air is introduced into a thermally stabilized stainless-steel chamber to compress and dissolve entrapped microbubbles within adhesive layers. This method ensures high reproducibility, avoids substrate warping or adhesive delamination associated with rapid vacuum cycling, and delivers superior interfacial bonding integrity. Each model complies with China’s GB/T 150.1–2011 requirements for Class I pressure vessels and is certified by the State Administration for Market Regulation (SAMR) for safe operation under regulated industrial conditions.
Key Features
- Four-stage programmable process control: (1) Preheating (temperature ramp-up, no pressure), (2) Pressurization (temperature hold + pressure ramp), (3) Deaeration (simultaneous temperature & pressure stabilization), and (4) Depressurization & cooldown (controlled pressure release and thermal recovery).
- PID-controlled heating system with ±3 °C temperature uniformity at 50 °C across the entire internal volume—achieved via centrifugal forced-air circulation without water-cooled shaft seals or maintenance-intensive bearings.
- Adjustable inlet/exhaust flow rates via calibrated regulators, enabling fine-tuned pressure ramping profiles compatible with sensitive optical adhesives and thin-film laminates.
- Full-spectrum safety architecture: dual-door position monitoring (open/closed + locked/unlocked), spring-loaded full-lift safety valve (set at 0.9 MPa MAWP), independent overtemperature cutoff (separate from main controller), low-inlet-pressure detection, motor overheat protection, and residual-current circuit breaker (RCCB) compliant with IEC 61000-4-5.
- Customizable chamber geometry: standard internal diameters range from Φ500 mm to Φ900 mm, with effective lengths from 850 mm to 1300 mm; non-standard dimensions available upon engineering consultation.
Sample Compatibility & Compliance
The YYK series accommodates rigid and flexible display modules—including TFT-LCD, OLED, and touch-integrated panels—up to the maximum internal envelope of each model. All chambers are constructed from electropolished SUS304 stainless steel with Ra ≤ 0.8 µm surface finish to prevent particulate shedding and facilitate ISO Class 7 cleanroom integration. The system meets ASME BPVC Section VIII Div. 1 design criteria for pressure boundary integrity, and its pressure regulation and temperature control subsystems conform to ISO 9001:2015 calibration traceability requirements. Documentation supports GLP-compliant validation protocols, including IQ/OQ documentation packages and 21 CFR Part 11–ready audit trails when paired with optional YAMATO DataLogger Pro software.
Software & Data Management
PLC-based control firmware supports up to five K-type thermocouple inputs for multi-point thermal mapping and real-time pressure/temperature logging at user-defined intervals (1–60 s). Digital setpoints for time (0–99 h 59 min), temperature (RT+10 °C to 70 °C), and pressure (0.101–0.7 MPa) are entered via membrane keypad with LED display. Optional Ethernet-enabled data acquisition modules provide CSV export, remote monitoring via Modbus TCP, and integration into MES platforms such as Siemens Opcenter or Rockwell FactoryTalk. All process logs include timestamped operator ID, parameter deviations, and alarm event codes—fully auditable for FDA or JIS Q 15001 regulatory submissions.
Applications
- Polarizer lamination debubbling in LCD module assembly lines
- Optical adhesive curing support for AR/VR waveguide bonding
- Encapsulation void mitigation in flexible printed electronics
- Pre-bonding conditioning of glass-to-glass laminates for automotive HUDs
- Reliability testing of adhesive shear strength under accelerated pressure-thermal stress
FAQ
What compressed air specifications are required for stable operation?
Dry, oil-free air at ≥0.05 MPa above operating pressure must be supplied through a 15A inlet port equipped with integrated coalescing filter and oil mist separator per ISO 8573-1 Class 2:2:2.
Can the chamber be validated for GMP environments?
Yes—each unit ships with factory-as-built dimensional drawings, material certificates (EN 10204 3.1), pressure test reports (1.25 MPa hydrotest), and calibration records for all sensors; IQ/OQ templates are available upon request.
Is remote diagnostics supported out-of-the-box?
Standard PLC firmware includes RS-485 Modbus RTU; Ethernet communication and web-based HMI require the optional YAMATO Network Interface Module (NIM-YYK).
What is the typical lead time for custom chamber configurations?
Engineering review takes 5 business days; mechanical fabrication and SAMR re-certification add 12–16 weeks depending on dimensional complexity and pressure class modifications.
Are spare parts and service contracts available globally?
YAMATO authorized service centers in EU, US, and APAC maintain stocked inventories of pressure regulators, PID controllers, safety valves, and door actuation assemblies; extended warranty and preventive maintenance plans are offered with annual calibration.
