DELO has an adhesive in its portfolio that is optimized to meet the high optical requirements of modern driver assistance systems. With it, the adhesive manufacturer is setting process speed and alignment accuracy standards for automotive cameras.
Advanced Driver Assistance Systems (ADAS) such as lane departure warning and emergency braking systems are becoming increasingly capable, steadily improving vehicle safety. High-resolution cameras are essential to many of these systems.
DELO has engineered a wide variety of products specifically designed for bonding and active alignment of automotive camers. We would like to illustrate just how capable these are by taking a closer look at one of these.
This dual-curing epoxy resin, part of our DELO DUALBOND family of adhesives, has a linear curing shrinkage that is reproducibly below one percent. In addition, the product exhibits extremely low swelling behavior, even under changing temperature and humidity conditions, so that camera focus remains optimally adjusted and can permanently fulfill its safety functions.
Since high-resolution cameras are primarily made of aluminum, the coefficient of thermal expansion (CTE) is specially adapted to this material. Application-relevant aging tests (e.g., +85 °C/85 % r. h., 2000 h) confirm the adhesive’s high bonding strength to aluminum substrates.
This dual-curing adhesive is particularly optimized for active alignment processes. With this method, now established in the automotive industry for manufacturing high-precision optical sensor systems such as ADAS cameras, image sensor data is actively read to determine the optimal sensor alignment to optics.
Due to the adhesive's rapid light fixation, the aligned components are precisely fixed within a few seconds and, from that point, reliably maintain their position. This makes it ideal for manufacturing processes designed for high volumes with demanding efficiency as well as alignment accuracy requirements. The final curing of the adhesive takes place via low heat at +80 °C.
This is also the latest active alignment adhesive to be added to DELO's product portfolio. In addition, we offer special adhesive and process technology solutions for LiDAR and RADAR systems.
