The Precision Challenge in Screen Chip Lamination
Modern smartphone screens demand ultra-precise bonding of display chips to substrates. Even minor force deviations can cause:
Micro-Cracks:Overpressure damages fragile OLED layers.
Adhesive Gaps: Insufficient force creates air pockets, reducing touch sensitivity.
Rework Costs: Manual corrections cost up to $12 per unit in premium devices.
How Electro-Pneumatic Valves Solve These Issues
1. Submicron Force Accuracy
Achieve 0.1–50 N control range with ±0.5% stability, critical for:
Ultra-thin glass bonding (<0.3mm)
Flexible OLED panel attachment
Pressure Feedback: Built-in sensors detect material deflection for instant compensation.
2. Dynamic Response for High-Speed Lines
20ms Step Response: Adjust pressure mid-cycle during multi-stage lamination.
Anti-Overshoot Algorithm: Eliminates force spikes during rapid tool engagement.
3. Smart Process Integration
PLC/HMI Compatibility: Program force curves via ModBus, PROFINET, or EtherCAT.
Vision System Syncing: Auto-correct pressure based on camera-detected chip alignment.
Recipe Management: Store 100+ profiles for different screen sizes/materials.
