- Protects sensors from dust and moisture as a sealing agent for the outer areas of image sensor packages. - Meets such needs as being antimony-free as an environmental regulation and having increased strength in association with narrower sealing in a hollow PKG structure. - Meets a variety of needs, such as corresponding to a higher aspect ratio by adding thixotropy in step with CSP, and blackening for higher sensitivity.
- Protects sensors from dust and moisture as an external sealing agent for image sensor packages. - Suppresses seal breakage by UV curing in the initial stage of processing, with outstanding strength that can endure expansion under internal pressure from reflow heating. - Contributes to not only the sealing performance but also to the prolongation of sensor life due to the unique design philosophy.
- UV curing enables temporary fixing, and heat curing enables full curing, bringing out strength even in places where light does not reach. - Has adhesiveness to LCP and other hard-to-bond plastics. - Meets various needs, such as high aspect ratio, active alignment, and light shielding.
- Protects lenses and other optical parts from shock with flexible hardness. - Enables adhesion to cycloolefin polymer and other hard-to-bond plastic parts. - Our lineup also includes high Tg grades with further increased strength.
- Produces integral-type lenses exceling in durability because the product is acrylic. - Can bond lenses of various materials. - Suppresses displacement after environmental tests due to its inherent flexibility.
- High-precision adjustment and fixing lens barrels/sensor circuit boards are completed by this one component, enabling UV + heat curing. - Excels in heat resistance, and is achieving an increasing share of use in dashboard cameras. - Makes it possible to obtain uniformly cured films because of UV and heat curing is performed in the same mechanism.
- Contributes to the improvement of light extraction efficiency and downsizing of devices. - Achieves a refractive index of 1.70 while being low in viscosity. - Reduces the negative effects of chemicals on components due to being solventless.
- Can hold bonded objects along desired coordinates by shape retention as coated and three-dimensional fixation. - Develops an adhesiveness to various adherends, such as glasses, plastics, and metals. - Small in curing shrinkage and excellent in chemical resistance and heat resistance because the base is epoxy.
