20W/cm²: The “Performance Ceiling” of Industrial Curing

While traditional mercury lamps still struggle within the 3-5W/cm² range, Futansi’s large-area UVLED light sources have achieved a peak intensity output of 20W/cm². What does this number mean?

In heavy-duty applications such as PCB solder mask curing, automotive coating, and 3D printing, high light intensity directly translates to production efficiency. Measured in seconds of curing time, a 20W/cm² light source can compress traditional multi-minute curing processes down to mere seconds, boosting production line throughput by an entire order of magnitude. Futansi overcame the heat dissipation and optical uniformity challenges at high power densities through multi-chip integrated packaging technology and microlens array optical design — a “thermal wall” that most manufacturers find insurmountable.

More critically, UVLED’s 20W/cm² is no “one-shot deal.” Unlike mercury lamps with their fixed spectrum, Futansi supports precise multi-band matching across 365nm/385nm/395nm/405nm, “prescribing the right cure” for the excitation peaks of different photosensitive resins, improving energy utilization by over 40%.

1mW/cm²: The “Embroidery Work” of Precision Manufacturing

If 20W/cm² represents “achieving miracles through brute force,” then the precise low-energy control at 1mW/cm² is “slow and meticulous craftsmanship.”

In applications such as semiconductor lithography, biochips, and precision electronic assembly, excessive light intensity can cause over-curing, thermal deformation, or even component damage. Futansi’s large-area light sources achieve stable output at the 1mW/cm² level through PWM stepless dimming technology and closed-loop optical feedback systems, with intensity fluctuations controlled within ±2%.

This capability is particularly vital in “delicate” processes such as medical consumable UV bonding and low-stress curing of optical lenses. Futansi’s solution: rather than simply reducing power, they maintain optical uniformity and wavelength purity at extremely low energy levels through zoned independent control and real-time spectral monitoring.

17 Years of Technical Depth: From “Can Do” to “Do It Well”

Since entering the UVLED field in 2007, Futansi has witnessed the industry’s complete evolution from “replacing mercury lamps” to “surpassing mercury lamps.” Its large-area light source product line covers multiple cooling solutions including air cooling, water cooling, and nitrogen protection, with single-unit equipment reaching a maximum irradiation area of 2m×1m, and supports modular splicing for expansion.

In terms of reliability, Futansi light sources generally exceed 20,000 hours of L70 lifespan (light degradation to 70%), more than 10 times that of mercury lamps. This means in 24/7 continuous production scenarios such as 3C electronics and new energy batteries, equipment downtime approaches zero.

From 1mW/cm² to 20W/cm², Futansi has proven over 17 years that the technical ceiling and floor of UVLED light sources are fundamentally a systems engineering challenge of optical design, thermal management, and intelligent control. While the industry still debates whether “high intensity is necessary” or “low energy is reliable,” Futansi has long provided the answer through its product portfolio — true professionalism means enabling users to obtain the optimal solution under any energy requirement.

Compared with traditional mercury lamp solutions, UVLED is reshaping the process standards of LCD production by virtue of its cold light source, instant on/off capability, pure spectrum, and energy-saving and environmentally friendly advantages.

UVLED Photolithography Exposure: Precision Transfer of Micron-Scale Patterns

In the ITO conductive glass manufacturing process for LCDs, UVLED exposure is the core step of photolithography.

The principle is as follows: by selectively irradiating an ITO substrate coated with photoresist using ultraviolet light at specific wavelengths (typically 365 nm or 395 nm), a photochemical reaction occurs in the exposed resist film area, thereby altering its solubility characteristics in the developer solution.

Leveraging the high uniformity of UVLED light sources (energy uniformity up to ±3%) and their fast on/off characteristics, a steep solubility contrast can be formed between exposed and unexposed areas. Subsequently, using the photoresist as a mask, the ITO conductive layer undergoes selective wet etching, ultimately yielding high-precision electrode patterns on the glass substrate that correspond exactly to the photomask, laying the foundation for subsequent pixel driving.

UVLED Surface Modification: Enhancing Interfacial Adhesion Between Films

In the production of display devices such as STN-LCD, the interfacial bonding quality between multi-layer thin films directly determines product reliability.

UVLED modification technology (ultraviolet surface property alteration) utilizes ultraviolet irradiation at specific wavelength bands to treat the surfaces of polymer film layers. Without damaging the substrate, it can:

• Break surface polymer chains to generate active free radicals;
• Introduce polar functional groups to increase surface energy;
• Significantly enhance physical anchoring and chemical bonding between film layers.

This technology is widely applied to enhance adhesion at critical interfaces such as ITO conductive films and photoresist films, TOP coatings and PI (polyimide) alignment films, effectively resolving process defects like delamination and peeling.

UVLED Curing: Reliable Locking of Liquid Crystal Cell Encapsulation

The encapsulation and curing of liquid crystal cells (panels) is a critical process step to prevent liquid crystal leakage and isolate moisture and oxygen. UVLED curing systems undertake two core tasks in this stage:

1. Sealant (Frame Sealant) Curing After empty liquid crystal cells are laminated, UV-curable frame sealant needs to be applied along the borders. UVLED area or line light sources can uniformly irradiate large-area adhesive layers, achieving simultaneous surface drying and deep curing within seconds, while avoiding the thermal expansion and contraction issues of glass substrates caused by the thermal radiation of traditional mercury lamps.

2. End Seal Curing After liquid crystal filling, the injection port of the liquid crystal cell needs to be sealed. UVLED spot sources can precisely focus on the tiny sealing area to achieve localized rapid curing, avoiding photochemical damage to liquid crystal materials from ultraviolet light, while ensuring that the seal achieves airtight sealing strength (adhesion strength >15 MPa).

UVLED Photo-Cleaning: Achieving Atomic-Level Clean Surfaces

Photo-cleaning (UV Cleaning) technology utilizes high-energy ultraviolet light (usually combined with ozone generation) to excite organic contaminants on material surfaces to undergo photosensitive oxidative decomposition reactions.

UVLED light sources can thoroughly mineralize contaminants such as grease, flux residues, and silicones into volatile substances such as CO₂ and H₂O.

After UVLED photo-cleaning, glass substrates and ITO film surfaces can achieve “Atomic Cleanliness,” with surface contact angles significantly reduced, providing a contamination-free physicochemical interface for subsequent processes such as coating, gluing, and lamination, substantially improving product yield.

FA array polishing refers to the process of implanting multiple fibers at precise pitches into a substrate (silicon, glass, or quartz) with V-grooves, followed by cutting, grinding, and polishing the end face to form an optically flat and smooth surface (flat PC, spherical PC, or angled APC), thereby enabling efficient, low-loss optical signal coupling and connection.

Core Objectives:

• Achieve high-precision fiber alignment;
• Minimize Insertion Loss (IL) to ensure smooth optical power transmission through the connection point;
• Maximize Return Loss (RL): Through specific end-face geometries (especially APC), reflected light is reduced to the lowest possible level, ensuring stable laser operation.

FA polishing is not performed arbitrarily; it is mainly classified into the following three types based on its optical function:

1. Flat / PC Polish The fiber end face is polished into an absolutely flat and smooth vertical plane (perpendicular to the fiber axis).

• Reflection reduction: High-precision polishing makes the end face as smooth as a mirror, reducing scattering loss;
• Physical contact: Used in applications requiring direct physical contact (butt coupling) between two fiber end faces to ensure maximum contact area;
• Applications: Multimode fiber connections, certain internal connections.

2. PC (Physical Contact) The fiber end face is polished into a tiny spherical (convex) surface.

• Air-gap elimination: When two PC end faces mate, the spherical design ensures that only the central portion makes contact, using the elasticity of the fiber to expel air from the contact zone. This greatly reduces Fresnel reflection and lowers return loss;
• Improved reliability: Prevents dust from being trapped between end faces;
• Applications: Early fiber connectors (e.g., FC/PC), certain internal optical module connections.

3. APC (Angled Physical Contact) The fiber end face is polished at a specific angle (typically 8°).

Complete reflection elimination: This is the most common and demanding process in FA polishing. According to optical principles, when light travels from the fiber (high refractive index) to air (low refractive index), if the end face is perpendicular, approximately 4% of the light is reflected back. This causes laser instability and increased signal noise. By polishing the end face to an 8° angle, reflected light does not return along the original path into the fiber core but is instead deflected into the fiber cladding and dissipated. APC end faces can provide extremely high return loss (typically >60 dB), which is a mandatory requirement for modern high-speed optical communications (such as FTTH, 5G fronthaul, and data center interconnects).

High-Efficiency UV Curing Equipment for Optical Module Packaging

Currently, the new industry standard for FA array fiber angle polishing adopts temporary bonding UV adhesive, cured with UVLED curing equipment, completely solving the fatal drawbacks of traditional wax processes.

1. Core Advantages:

• Liquid gap-filling: Before curing, it is a liquid that can flow like water into the finest gaps, ensuring 100% support between fibers and preventing edge collapse;
• Solid rigidity: After irradiation by a UVLED curing system, the adhesive instantly transforms into a hard, glass-like solid (hardness Shore D>80), locking the fiber array into a monolithic structure like cement. This ensures zero deformation during grinding, guaranteeing the precision of the angle and flatness;
• Low-temperature, non-damaging: Modern UVLED curing equipment employs cold-light-source technology with virtually no infrared thermal radiation. The workpiece surface temperature rise during curing is ≤5°C, avoiding thermal damage to fiber coatings, plastic components, and PLC chips caused by the high temperatures of traditional mercury lamps, and ensuring waveguide refractive index stability;
• Chemical resistance: The cured adhesive layer can resist erosion from polishing slurries (ethylene glycol-based, aluminum oxide/silica suspensions).

2. Key Role of UVLED Curing Process

UVLED curing equipment is the core apparatus that transforms FA temporary protective adhesive from “liquid gap-filling” to “solid rigidity.” Its technical characteristics directly determine grinding precision:

• Precise spectral matching: Utilizing 365 nm/385 nm/395 nm wavelengths, it precisely matches the absorption peaks of the UV adhesive photoinitiators, with a compatibility rate exceeding 98%, ensuring synchronous curing of deep adhesive layers;
• Programmable alternating high/low irradiance: To avoid internal stress concentration, cover plate debonding, or deformation displacement caused by one-time high-irradiance curing, advanced UVLED curing machines support programmable irradiance control. For example, a preliminary exposure at 20 mW/cm² low irradiance for 30 seconds allows the adhesive to initially set and release partial stress; it then automatically switches to 80 mW/cm² high irradiance for 30 seconds to complete full curing. This “low-stress curing” mode is crucial for ensuring sub-micron alignment precision;
• Multi-form light source adaptation:
  • UVLED spot source: Suitable for local supplementary curing or precise curing of single-channel FAs;
  • UVLED area source: Suitable for synchronous and uniform curing of entire multi-core FA arrays, with energy uniformity reaching ±3%, ensuring consistent force on each fiber;
  • UVLED line source / tunnel curing machine: Can be integrated with production lines to achieve continuous inline curing, significantly improving production efficiency;
• High efficiency and environmental protection: UVLED equipment consumes only 20% of the energy of traditional mercury lamps, contains no mercury or other hazardous substances, boasts a service life exceeding 20,000 hours, requires no warm-up, and is ready to use immediately upon switching on.

3. Key Feature: Water-Soluble Removal

Non-damaging cleaning: No need for strongly corrosive acetone, avoiding solvent damage to fiber coatings or plastic components, achieving residue-free, non-damaging cleaning.

Debonding principle: After polishing is completed, the entire assembly is soaked in hot water at 60–80°C. The adhesive absorbs water, swells, softens, and finally peels completely away from the fiber surface;

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%.

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%.
