Introducing Flashbond UV-3720 for Active Alignment Applications

In the world of optics and photonics, precision is key. Whether you’re working with lasers, lenses, or fiber optics, active alignment is a crucial process that demands adhesives that can meet the highest standards of accuracy, strength, and reliability. This is where Flashbond UV-3720 comes in, offering an advanced solution specifically designed for active alignment applications.

What is Flashbond UV-3720?

Flashbond UV-3720 is a high-performance, UV-curable adhesive formulated to provide optimal performance in active alignment tasks, commonly found in industries such as optics, telecommunications, medical devices, and photonics. It has been engineered for superior bonding strength, optical clarity, and fast curing times, making it a go-to choice for manufacturers who need a precise, reliable, and efficient solution for bonding components in active alignment processes.

Key Features of Flashbond UV-3720

1. Fast Cure Time
One of the standout features of UV-3720 is its rapid curing time when exposed to UV light. The quick curing process helps streamline production, enabling faster throughput and reducing cycle times without compromising on the strength or quality of the bond. This feature is especially valuable in high-volume manufacturing environments, where efficiency and speed are critical.

2. Low Cure Shrinkage
When working with optical components, low cure shrinkage and minimizing distortion is essential. Flashbond UV-3720 offers low cure shrinkage under 0.1%, ensuring minimal impact on the performance of the optical system. Whether it’s for aligning lenses, mirrors, or fibers, the adhesive is perfect to holding alignments, providing reliable performance without introducing unwanted artifacts.

3. High Bonding Strength
Flashbond UV-3720 has been formulated to deliver superior adhesion to a variety of materials, including glass, metals, and ceramics. This makes it suitable for a wide range of active alignment applications, where bond integrity is paramount. Its high bonding strength ensures that components stay securely in place throughout the alignment process and during the device’s operational life.

4. Thermal and Chemical Resistance
Active alignment often takes place in environments subject to varying temperatures and potential exposure to chemicals. Flashbond UV-3720 has outstanding thermal and chemical resistance, allowing it to perform reliably even under challenging conditions. Whether your application is exposed to heat, humidity, or chemicals, you can trust that UV-3720 will maintain its strength and durability.

Applications of Flashbond UV-3720

Flashbond UV-3720 is the perfect adhesive for a variety of active alignment applications, including:

• Optical fiber alignment and bonding
• Laser diode and lens assembly
• Microscope and camera alignment
• Telecommunications equipment
• LiDAR Sensors and photonics systems

It is particularly beneficial in micro-optics and precision alignment systems where minimal misalignment is allowed and quick, secure adhesion is necessary.

Why Choose Flashbond UV-3720?

When precision is essential, having the right adhesive can make all the difference. Flashbond UV-3720 is engineered for high accuracy and reliability in active alignment applications. Its combination of fast cure times, low cure shrinkage, and strong adhesion make it the ideal choice for engineers and manufacturers in optics, photonics, and other high-tech fields.

Conclusion

Designed for active alignment application on optical assemblies, camera modules, and LiDAR, Flashbond UV-3720 UV is a filled low-shrinkage, light-curable epoxy. It is formulated to be heat curable at moderately high temperatures for application where the adhesive cannot be exposed to light. The active alignment adhesive has exceptionally low cure shrinkage under 0.1%. It is a one part, dual cure (UV or HEAT) system with a high Tg of 155°C, a low CTE of 30pm/°C and can withstand 85/85 for 1000 hours with very low moisture absorption. It is perfect for holding alignments through a temperature range of -55 to 200°C

The product can be cured using heat only in the absence of the above light or in conjunction with light curing. It recommended for heat only cure at 85°C 50-60 minutes and 125°C 10-15 minutes.  Actual times can vary based on part configuration, oven exposure, mass of adhesive and volume. 

Whether you’re working with delicate optical components or demanding photonics systems, Flashbond UV-3720 provides the performance and reliability required for optimal active alignment. By offering a fast cure, strong bond, and minimal impact on optical performance, it ensures your alignment processes are both efficient and accurate.
