DELO adhesives for smartphone cameras
As a manufacturer of smartphone cameras, you face the challenge of integrating more and more functions into the smallest possible space. The increasing complexity of camera modules requires highly specialized adhesive solutions.
DELO delivers exactly that: a versatile portfolio providing the perfect solution for more than 30 bonding points in smartphone cameras.
Perfect for over 30 bonding points in camera modules
DELO offers adhesive solutions for all essential bonding points of a smartphone camera. These include the active alignment of the lens package to the image sensor, the attachment of the lens barrel and the voice coil motor (actuator). As a technology leader, we also have proven solutions for innovations such as moving iris (camera aperture) and periscope cameras.
Bonding components can be fixed in less than a second. Dual-curing technologies based on DELO's own chemistries enable particularly fast processes. The adhesives reach their full strength at temperatures starting from 50 °C. They are therefore also suitable for particularly temperature-sensitive materials.
The low temperature curing minimizes outgassing and thus avoids problems such as condensation. Thanks to their high moisture resistance, adhesion and flexibility, the adhesives contribute to the long-term durability of the cameras even under adverse conditions.
DELO also offers suitable adhesive solutions for the possible additional requirement of electrical or thermal conductivity.
Active alignment
Maximum manufacturing efficiency and process safety with DELO
Active alignment for your camera modules is all about perfection. Exact dosing, ultra-fast fixation, and reliability are decisive for the quality of your optics. The DELO DUALBOND LT product family offers the ideal solution.
Active alignment requires maximum precision to ensure that your camera modules deliver the best possible image quality. When aligning optical components such as lenses and image sensors, it is crucial that they remain fixed in position once optimally aligned. Thanks to the fast light fixation of our adhesives, the components are securely fixed in less than one second and reliably maintain their position until final curing.
The extremely short light fixation time of less than one second enables particularly fast cycle times in active alignment. In addition, dual-curing technology ensures effective curing of hard-to-reach shadowed areas of your camera modules by means of heat curing. These adhesives cure at low temperatures, making processes energy-efficient, protecting the substrates to be joined, and resulting in a low-stress bond.
In combination with DELOLUX UV lamps, components can be fixed in an instant, while heat-based curing times remain short and further accelerate production processes.

Lens Barrel Attach (LBA)
Maximum efficiency and process reliability in manufacturing
The lens barrel attach is a key step in the production of camera modules, where speed plays a decisive role. This is precisely where the DELO DUALBOND LT product family demonstrates its particular suitability.
In the lens barrel attach process, the lens assembly must be securely and precisely bonded to the housing. DELO adhesives ensure reliable bonding and make a decisive contribution to the mechanical stability and high optical quality of the entire system.
Maximum precision in record time: the DELO DUALBOND LT products enable ultra-fast light curing in less than one second and reliable heat curing in shadowed areas. This saves energy, protects sensitive substrates, and results in low-stress bonds. In combination with DELOLUX UV lamps, components can be fixed in an instant, further accelerating manufacturing processes.
The adhesives stand out for their durability, robustness, and cost-efficient manufacturing processes – providing an ideal solution for the production of high-quality camera modules.
Voice Coil Motors (VCM)
High-precision, flexible solutions for the reliable assembly and performance of modern actuators
Voice coil motors (VCMs) are essential for autofocus and image stabilization in smartphone cameras. Since these miniature electric motors are composed of temperature-sensitive materials, this places high demands on production processes. The DELO DUALBOND LT product family is the ideal solution thanks to its low-temperature curing.
Because of the very small size of VCM components, especially fine and precise bonding is required. DELO adhesives meet these requirements and ensure reliable stability.
The adhesives of the DELO DUALBOND LT family cure at low temperatures. This makes production processes energy-efficient and protects the substrates. Their low viscosity enables extremely fine bond lines, making them ideal for microtechnology applications. They are also characterized by high shear strength and support fast, reliable production processes. In combination with DELOLUX UV lamps, components can be fixed within fractions of a second. Short heat-curing times accelerate processes even further, consolidate production steps, and increase overall efficiency.
The adhesives of the DELO DUALBOND LT product family provide tailored solutions for the specific requirements of VCM production. Learn more about DELO DUALBOND adhesive solutions.
First Lens Bonding
Laying the foundation for excellent camera optics
The first lens bonding process is a crucial step in the production of camera modules. The uppermost lens must be positioned with pinpoint accuracy and securely bonded to the lens holder or frame.
Using the right adhesive chemistry, this critical connection minimizes potential distortions caused by production tolerances. As such, the first lens bonding process lays the foundation for the long-term optical performance of the entire camera system. The DELO DUALBOND SJ and DELO PHOTOBOND FB product families provide ideal solutions for this step.
The DELO DUALBOND SJ product family impresses in first lens bonding with fast light fixation and a subsequent heat-curing process, making it ideal for hard-to-reach shadowed areas. These adhesives also provide outstanding flexibility, which makes them suitable for a particularly wide range of applications.
The DELO PHOTOBOND FB product family is characterized by extremely fast light fixation in just 1 to 5 seconds and offers improved surface dryness compared to acrylates.
These adhesives increase the durability and resistance of camera modules thanks to their stress-relieving properties. Learn more!
Periscope Cameras
Maximum precision for outstanding optical quality
Periscope cameras are a groundbreaking innovation in smartphone technology. They enable true optical zoom in an exceptionally compact design. Unlike conventional camera modules, periscope cameras use a system of mirrors and/or prisms that deflect light at an angle towards the image sensor. This creates a greater focal length without requiring extra space in terms of smartphone thickness.
These cameras place the highest demands on manufacturing: mirrors and prisms must be positioned and bonded with utmost precision. Only then can the optical axis be perfectly aligned, ensuring distortion-free images and eliminating visual defects.
The prism attach bond is the main connection that securely fixes the prism within the periscope module. This joint is crucial for keeping the prism stable in position and ensuring precise optical alignment – a key factor for the image quality of your cameras.
The prism side fill bond provides additional support by stabilizing the sides of the prism. This secondary connection not only contributes to the structural integrity of the overall system but also helps absorb vibrations and impacts that occur during everyday use. By applying DELO adhesives with controlled flow behavior evenly along the prism sides, the risk of stress cracks is minimized and the service life of your cameras is significantly extended.
Thanks to an extremely short light fixation time of less than one second, the DELO DUALBOND LT series enables particularly fast cycle times. In addition, dual-curing technology ensures effective curing in hard-to-reach shadowed areas by means of heat curing. The adhesives in this series cure at low temperatures, making processes energy-efficient and protecting the substrates.
For side-fill applications, the controllability of the adhesive’s flow behavior is especially important, particularly in narrow gaps. This makes it possible to design processes in which the entire available surface can be optimally utilized. DELO DUALBOND LT adhesives are optimized for this controllability.
In combination with DELOLUX UV lamps, components can be fixed within fractions of a second, while heat-curing times remain short and further accelerate production.
