Secondary Mounting Underfill

Improve mount reliability of consumer and automotive parts

We offer a product lineup for various applications such as consumer and automotive. Solder joints of various semiconductor packages and electronic components can be reinforced.

• High reliability
  Designed for high thermal shock resistance with high Tg and low CTE. This provides more reliability in harsh environments such as in-vehicle, base stations, and data centers.
• Stress reduction technology
  Silicone-modified epoxy technology reduces internal stress after curing and absorbs the strain caused by the difference in the coefficients of linear thermal expansion between the substrate and the semiconductor package.
• Epoxy toughening technology
  Toughness of the epoxy resin is increased by dispersing the submicron rubber particles. This provides better drop impact resistance required for mobile devices.

Thermal Conductive Material

Heat dissipation adhesive / heat dissipation gel

Because the material is in liquid form and heat conductive, it shows excellent adhesion to the adherend and high heat dissipation performance.We can offer products so that they flexibly match your heat dissipation designs, such as thermal conductivity, cure conditions and viscosity.

• Reduce contact thermal resistance and improve thermal conductivity by thin film coating.
  Since the material is liquid, it adheres to the adherend surface very well. It can also be applied as a thin film, its heat dissipation performance is better than that of a heat dissipation sheet.

• High reliability
  The product uses highly heat-resistant epoxy or silicone as the base resin, and is ideal for automotive equipment which tend to become hot. Epoxy adhesives show excellent adhesive properties. Silicone gels can reduce stresses on parts due to its low hardness, and can also be repaired.
• Low viscosity design
  Low viscosity is achieved by selecting the resin and type, particle shape and particle size of the heat conductive filler. This enables various applications such as injection into narrow gaps and filling into voids.

Adhesive for In-vehicle Displays

Contributes to improve design flexibility of in-vehicle displays

In-vehicle displays are becoming larger, deformed and curved. In the assembly process of such displays, using adhesive between the cover glass and the resin panel instead of double-sided tape improves reliability, productivity (automation) and reduces costs.

• Excellent elasticity and adhesion
  When the product is used as an adhesion between different materials such as glass and resin, it shows elastic behavior and adhesiveness that compensate the different coefficients of linear thermal expansion between two adherends due to temperature change. Therefore, it can provide adhesion reliability for in-vehicle displays in the harsh environment.
• Application flexibility
  Productivity can be improved by automatic application with a dispenser. Narrow bezels can be applied by fine application. The product having highly thixotropic property allows user to apply it at the desired width and height, which is capable of sufficiently absorb a dimensional tolerance of adherends.
• Fast curing
  The product can gain adequate adhesion strength in as early as five minutes after application and proceed to the next process.
