As 400G/800G high-speed optical transceiver modules enter large-scale mass production, the packaging process demands for curing equipment have become increasingly stringent. The UVLED curing chamber, a critical device in transceiver module manufacturing, is progressively replacing traditional mercury lamp solutions and becoming the mainstream choice across the industry.

Why UVLED Is Essential for Transceiver Module Curing?

Transceiver modules integrate precision components including laser diode (LD) chips, photodetector (PD) chips, lenses, and fiber array units (FAU). Their adhesive bonding and sealing protection heavily rely on high-quality UV adhesive curing. Traditional mercury lamp curing suffers from excessive thermal radiation and uncontrollable temperatures, which can easily damage thermal-sensitive components and lead to optical power degradation. As a “cold light source,” the UVLED curing chamber keeps surface temperature rise within 5°C, fundamentally preventing high-temperature damage to laser chips and precision lenses, with optical power degradation rate reduced to below 0.1 dB per 1,000 hours.

Core Selection Criteria: Wavelength, Energy, and Uniformity

1. Precise Wavelength Matching: The absorption peaks of acrylic/epoxy UV adhesives commonly used in transceiver module packaging concentrate at 360–370 nm. Therefore, 365 nm single-band UVLED point sources are the preferred solution, boosting photoinitiation efficiency by over 30% and ensuring curing depth ≥1 mm with bonding strength ≥25 MPa.

2. Micro-Zone High Energy Density: For micron-level bonding points between fiber arrays and lenses in high-speed QSFP-DD/OSFP modules, the spot diameter needs to support Φ1–5 mm adjustable range, with irradiance ≥2000 mW/cm² and closed-loop feedback fluctuation ≤3% to meet precision curing requirements.

3. Illumination Uniformity: Area light source design must guarantee illumination uniformity above 90%, ensuring uniform UV adhesive curing across TOSA/ROSA component surfaces and gaps, preventing optical path deviation caused by insufficient local adhesive strength.

Typical Application Scenarios

In fiber array (FA) to PLC chip bonding, UVLED curing chambers achieve rapid 3–5 second curing with insertion loss deviation <0.05 dB. In TOSA/ROSA component packaging, combined with automatic alignment systems, shadow-free curing can be realized with hermetic seal pass rates improved to 99.5%. For lens and fiber end-face fixation, precise light control optimizes coupling efficiency from 0.7 dB to 0.25 dB.

Current mainstream UVLED curing equipment supports one-to-four multi-channel independent control for synchronous/asynchronous operation, adapting to multi-station production lines with capacity reaching 1,500 units per hour. Devices are generally equipped with RS232/485 interfaces for MES system integration and curing data traceability. Some manufacturers also offer light field simulation services to optimize the relative angle between light source and fiber array, ensuring energy coverage uniformity >95%.

Precision UV Curing Optical Adhesive Applications in Optical Splitter Manufacturing

In the production of PLC planar lightwave-guide (PLWG) optical splitters, the bonding and adhesive UV curing of the chip to the fiber array (FA) is a critical process step. The alignment accuracy between the fibers and the waveguide must be controlled to the sub-micron level, and the UV curing optical adhesive layer is only 5–10 μm thick. Any curing shrinkage or thermal stress can cause positional shifts, directly affecting insertion loss. Futansi’s best UV curing light solution utilizes a precise 365 nm wavelength that perfectly matches the absorption peak of the acrylate UV curing adhesive’s photoinitiator. Combined with a matrix-style LED chip and a compound lens assembly, it achieves a stable output with energy uniformity of ±3%, ensuring consistent deep curing of the acrylic resin UV curing adhesive layer and controlling curing shrinkage to below 0.5%. Its low-temperature curing capability operates at ≤45°C, preventing deformation of the PLC chip’s silicon-based materials and the optical fiber coating layer caused by thermal stress. Post-curing, waveguide transmission loss can be controlled below 0.1 dB.

High-Efficiency UV Curing Equipment for Optical Module Packaging

As core components of optical communication systems, the packaging processes of optical modules directly impact transmission performance and reliability. In the packaging of TOSA/ROSA modules, the bonding and fixation of the laser chip, lens, and fiber end-face are extremely temperature-sensitive. Traditional UV curing bulb systems involve infrared thermal radiation, with surface temperatures reaching over 200°C, which can easily cause performance degradation in VCSEL lasers. In contrast, Futansi’s UV curing device employs a pure cold light source architecture, resulting in a temperature rise of less than 5°C on the illuminated surface, thereby increasing the yield of temperature-sensitive devices from 85% to 98%.

For the fiber array end-face bonding in 400G/800G high-speed optical modules, Futansi’s 1-to-4 UV curing equipment system supports multi-channel synchronous adhesive UV curing.
