What is Optical Clear Adhesive (OCA) Bonding?
Optically clear adhesive (OCA) bonding adheres display layers together with a sheet adhesive to maximize optical clarity.
In our previous blogs in the display bonding technology series, we discussed air gap bonding and liquid optical clear adhesive (LOCA) bonding. In the final blog of our three-part bonding technologies series, we focus on the most widely used display bonding capability at Boyd: optically clear adhesive (OCA) bonding.
What is the Process Behind Optically Clear Adhesive (OCA) Bonding?
- two or more rigid components.
- OCA Bonding: A roller pushes all the air out from between the flexible component and substrate (either flexible or rigid)
Why Choose Optically Clear Adhesive (OCA) Bonding?
The main advantage of optically clear adhesive bonding technology is thinner bond lines. Where liquid optically clear adhesive (LOCA) bonding can achieve a bond line between
Another advantage of optically clear adhesive bonding is that the sheet adhesive does not require curin faster . Using a sheet adhesive also provides tighter tolerance, more consistent flat bond line wh No special dispensing equipment is needed.
While there are several benefits to using optically clear adhesive, it may not be suitable for all applications. Unlike LOCA bonding, optically clear adhesive results in a bonded adhesive that cannot be reworked, which requires a more rigorous inspection and testing process to ensure high manufacturing yields.
Boyd offers a wide variety of bonding options to meet unique project needs, providing the best-fit solution for your application. To learn more about the process behind our display bonding technologies, read our other blogs listed below or reach out to our experts.
