The Reason for OCA Air Bubbles Occurred During OCA Laminating and Deal methods for removing Bubbles

OCA is widely used in the screen repair business , during working , there will be some problems occurred , for example , Air Bubbles . Why the bubbles come ?and How we should deal with them ?

OCA adhesive is mainly used in the construction of G + P PET cover and PC board. Which is more suitable for OCA glue ? The thickness of the cover plate PC usually is about 0.5mm / 0.75mm, the thickness of the PET cover is typically 0.25mm, after bonding/Laminating PET cover, rebound is relatively small, is not eady to have air bubbles, but after bonding /laminating the cover plate PC, because the PC cover is thick, gelatinous hard, easy to rebound, bubbles occurred in the marginal place. Another situation, if we don't print the insulating layer on the glass , then cannot prevent the rebound.

We do analyze on the root bubble, dig the bubble , watch by the microscope , you can see the bubbles occurred on the PC cover, confirms PC cover reasons, mainly because PC cover caused a rebound. South Korea, Japan, several brands have shown a series of OCA manufacturers earlier occurrence of bubbles on the PC plate appearances. Advocates, customers cover into PET, reduce the thickness of the insulating layer, use thicker OCA, use a soft gelatinous, viscous strong OCA.
