optoelectronics_lens_bonding

Nowadays, LED illumination is used all over the world. Their key pros: They save energy and costs, and have a long lifetime. Therefore, DELO has developed adhesives which are advantageous especially in terms of outgassing, thermal resistance and UV stability.

Applications

  • Lens bonding / flash lens bonding
  • Bonding of protective glass covers for LED arrays

Properties

  • High yellowing resistance
  • Low outgassing
  • Very low shrinkage
  • Good adhesion to glass, ceramic, aluminum and plastic
  • Halogen-free (IEC 61249-2-21)

Wafer level / micro-optics

For new and consistently improved products, such as mini-3D-cameras for mobile phone, beamers for smartphones and 3D screens, micro-optics are becoming more and more important. With newly developed, fast-curing and highly transparent imprint materials, DELO enables its customers to push forward these developments.
The lenses are produced by molding. Corresponding adhesives are also available for wafer bonding.

Applications

  • UV replica processes and micro-lens imprint

Properties

  • High yellowing resistance at elevated temperatures, especially in reflow processes
  • Very high transmission in the visible range
  • Low outgassing
  • Very low shrinkage
  • Excellent adhesion to glass with simultaneous debondability from punch materials
  • Halogen-free (IEC 61249-2-21)

Mini-camera applications

High-resolution mini-cameras in mobile phones (compact camera modules) and cars (front and rear view cameras) will be key features of these two markets in the future.
DELO adhesives are especially adapted to these requirements and enable a highly accurate adjustment of the optical axis (active alignment) and high optical quality in the long term.

Properties

  • Active alignment with high precision
  • Fast UV fixation
  • Low-temperature curing at less than +80 °C
  • Halogen-free (IEC 61249-2-21)
