CG+OCA Vacuum Bonding Machine. Bonds Cover Glass (CG) to display assemblies using OCA (Optically Clear Adhesive) film under vacuum pressure. Delivers precise, bubble-free optical bonding for smartphone and tablet screen refurbishment with superior display clarity.
Frequently Asked Questions
What is the difference between the CG+OCA Vacuum Bonding Machine and the CG+OCA Vacuum Laminating Machine?
The vacuum bonding machine uses a chamber-based vacuum bonding process with higher vacuum levels and more precise pressure control, while the laminating machine uses a roller or press-based lamination approach. The bonding machine is better suited for applications requiring the highest optical clarity and minimal bubble risk.
What OCA film thicknesses work best with this CG+OCA vacuum bonding machine?
Standard OCA film thicknesses of 100μm to 250μm are compatible with this machine. Thicker OCA films may require adjusted pressure settings. Please contact our team for recommendations based on your specific cover glass and display assembly.
How long does a typical CG+OCA bonding cycle take?
A typical bonding cycle takes approximately 1–3 minutes depending on the panel size and OCA film type. The vacuum pump-down time adds additional time before the bonding pressure is applied. Contact our team for detailed cycle time specifications.
Does this machine require calibration before use?
Initial calibration of vacuum level, pressure, and timing parameters is recommended before production use. Our team provides setup guidance and calibration support to ensure optimal bonding results from the first cycle.
