Bonding Solutions for Automotive Cameras

Automotive portfolio for state-of-the-art camera technology

Cameras play a decisive role in the further development of automated driving systems. They are essential for the perception of the environment and enable the vehicle to recognize different road scenarios in real time. In assisted driving, cameras support essential functions such as lane departure warning, adaptive cruise control and emergency brake assist and thus make a decisive contribution to increasing safety, functionality and comfort in the vehicle. In more advanced automated driving systems, cameras are an integral part of the comprehensive understanding of the vehicle environment and allow navigation and decision-making with minimal human intervention.

Overall, cameras are indispensable on the road to safer, more efficient and autonomous transportation solutions and contribute significantly to the reduction of traffic accidents and the transformation of mobility. For this reason, correspondingly high demands are placed on the manufacture of cameras and their functionality. Thanks to their versatile and specific properties, adhesives make a decisive contribution to ensuring that modern cameras meet the high requirements of the automotive industry.

Many years of experience at all levels of camera production

Based on more than 15 years of expertise in the field of camera assembly, DELO has developed a broad product portfolio for bonding applications in automotive cameras. This covers, among other things, the bonding processes related to chip-on-board technology, connector encapsulation, module fixation and the active alignment of optics and image sensor. DELO's adhesives enable increasing miniaturization and withstand external influences such as extreme temperature fluctuations, changing humidity levels and vibration loads.

Technical details and special features

For precise camera mounting, DELO has developed special epoxy resin adhesives that can be cured either by light and heat or purely with light. Technical features of these products are e.g:

• Fast fixation with UV light: Fixation times of 0.5 - 1 s enable high cycle times and optimum system utilization.
• Low shrinkage and swelling behavior: The movement of the adhesive over the lifetime of a camera is reduced to a minimum.
• Universal adhesion: DELO adhesives offer high reliability and aging resistance on common camera substrates.

Application areas of DELO adhesives

DELO adhesives are used in a variety of camera applications in cars, e.g. for:

• Front cameras (mono and stereo modules, telephoto camera)
• 360° surround view perception
• Near range perception
• Infrared cameras (interior observation, thermal imaging cameras)

Versatile Adhesive Solutions for RADAR Sensors

Highest Quality Under Difficult Conditions

ADAS technologies have become an integral part of the automobile, with RADAR being one of the most established technologies. Functions such as adaptive cruise control or blind spot assist must also function smoothly in difficult weather conditions. The RADAR sensor has proven to be the most durable technology in this respect over the last few years and therefore also requires special durability requirements for adhesives. For example, they must be able to withstand splash water, salt, vibrations, strong temperature fluctuations and aggressive media without losing their functionality. The special feature here is that this not only concerns the functionality of the adhesive effect, but also often includes physical properties such as certain conductivities or electromagnetic shielding.

DELO offers specialized adhesives that reliably protect RADAR sensors so you can count on your RADAR technology in any weather. Our solutions are fast and easy to process.

Why choose DELO adhesives?

DELO's light-curing epoxy resins of the KATIOBOND family offer a solution for demanding conditions. They are resistant to temperatures from -40 to +125°C and pass extensive salt spray tests. These adhesives enable efficient production processes through pre-activation and fast curing. They impress with:

• High resistance: Resistant to moisture, chemicals and temperature stress.
• Fast curing: Optimized production cycles thanks to innovative, low-energy light curing processes.
• Shielding: EMI protection of electrical components.
• Conductivity: Dissipation of heat and electrical contacting

Applications of DELO adhesives

Our adhesives are indispensable in numerous RADAR applications:

• Adaptive cruise control (ACC)
• Emergency Brake Assist (AEB)
• Blind spot detector (BSD)
• Lane change assistant
• Rear collision warning

Bonding Ultrasonic Sensors for more than 10 Years

Signal transmission through adhesives

With ultrasonic sensors, you are faced with the challenge of not only bonding the components for signal generation but also transmitting their signal in the best possible quality. To transmit the sound pulses, the mechanical properties and adhesive layer thickness must match precisely.

DELO has the solution for your ultrasonic sensors: Our high-tech adhesives combine long-term proven functionality and optimize your production processes. They have been used for more than a decade for the assembly of parking sensors, combining the necessary application and process expertise.

Properties of DELO adhesives

Our light-curing epoxy resins of the DELO KATIOBOND family have been specially developed for the challenges of ultrasonic sensors. They not only withstand temperatures ranging from -40°C to +125°C, but also reliably hold the components together under vibration loads with the thinnest adhesive layer thicknesses.

Our products offer:

• Outstanding signal transmission: Tailor-made properties for thin adhesive gaps.
• Robust against environmental influences: Temperature and media resistance even under extreme conditions.
• Efficiency for your production: Short cycle times and low-energy light pre-activation.
