Bubble Removal Machine. Professional autoclave machine for removing air bubbles from OCA-laminated smartphone and tablet screens. Uses high-pressure air to compress and dissolve trapped bubbles in the OCA adhesive layer, producing optically clear, bubble-free lamination results.
Frequently Asked Questions
How does a bubble removal machine work?
The bubble removal machine is an autoclave that applies high-pressure compressed air (typically 3–6 bar) to screens placed inside its sealed chamber. The pressure compresses trapped air bubbles until they dissolve into the OCA adhesive, permanently eliminating them from the lamination.
Is a bubble removal machine always necessary after OCA lamination?
A bubble removal machine is strongly recommended after OCA lamination, especially for non-vacuum lamination methods. Even with vacuum lamination, small residual bubbles can form and are best eliminated with an autoclave cycle before the OCA adhesive fully cures.
What is the difference between a bubble removal machine and a defoaming machine?
A bubble removal machine (autoclave) uses high-pressure air to dissolve bubbles in OCA-laminated screens. A defoaming machine typically uses vacuum or vibration to remove bubbles from liquid adhesives before application. Both serve different stages of the lamination process.
Can a bubble removal machine be used for both OCA film and SCA liquid adhesive lamination?
Yes, bubble removal machines are effective for both OCA film and SCA liquid adhesive lamination. SCA assemblies may require slightly different pressure and temperature settings. Always refer to the adhesive manufacturer’s guidelines for optimal autoclave parameters.
