How to Choose the Right UV LED Spot Curing
✅ 1. Define Your Application and Curing Area
Start by identifying the type of material and the size of the curing spot:
-
Micro-bonding (e.g., sensors, catheters) → Requires a small-diameter light guide (1–3 mm)
-
General precision assembly → Use a medium spot size (3–10 mm)
-
Multiple curing points → Consider a multi-head output or light splitting system
▶ Tailor the system to your required spot size, depth of cure, and part geometry.
✅ 2. Select the Right Wavelength
Different UV-curable materials respond best to specific wavelengths:
-
365nm – Deeper penetration, ideal for thicker adhesives or opaque substrates
-
385nm / 395nm – Common for general-purpose UV adhesives and coatings
-
405nm – Faster surface curing, often used with clear or thin-layer resins
▶ Always match the wavelength to your adhesive/resin’s technical datasheet.
✅ 3. Choose the Correct Light Guide
-
Fiber or liquid light guides vary in flexibility, durability, and transmission efficiency
-
Select the length and diameter that suits your setup (e.g., tight spaces, robotic arms)
-
Some systems support interchangeable light guides for versatility
▶ Shorter, high-quality light guides typically offer higher intensity and more consistent output.
✅ 4. Consider Curing Intensity and Time
Check if the system can deliver sufficient UV power (measured in mW/cm²) to cure your material:
-
Low-intensity systems (~1000 mW/cm²) for sensitive or low-viscosity adhesives
-
High-intensity systems (2000+ mW/cm²) for fast curing or high-volume production
▶ Some systems offer adjustable intensity for greater process control.
✅ 5. Look for Control and Integration Features
For efficient operation and automation:
-
Foot switch or timer mode for manual setups
-
PLC or external trigger support for automated production lines
-
Multi-channel controllers for simultaneous curing at different points
▶ Choose a system that fits your workflow—whether benchtop, semi-automatic, or inline.
✅ 6. Check for Thermal Management
-
Passive cooling is enough for low-duty cycle use
-
Active cooling (fans or heat sinks) is needed for continuous, high-power applications
▶ Proper cooling extends LED lifespan and ensures stable curing performance.
✅ 7. Safety and Ergonomics
-
Look for UV shielding accessories (e.g., safety glasses, shrouds)
-
Consider compact and ergonomic designs for operator comfort
-
Ensure certifications (CE, RoHS, ISO) for lab or cleanroom use
