SC-225 LED Spot-Curing System

Control up to Four LED Heads Independently for Greater Curing Flexibility

The SC-225 is the next step in high-performance LED spot curing units. This small, versatile unit offers high intensity, long die life, and great PLC functionality. The system is compromised of a controller with an easy-to-use control interface and up to four LED heads.

The SC-225 is designed for flexible operation, using LEDs installed directly at the end of the head for precision light delivery. The small diameter LED heads can be mounted very close to the piece being cured, covering hard-to-reach portions of complex geometries or providing 360° cures, and providing maximum intensity via the short working distance (focused at 5 mm). With 4 independently operable channels, multiple LED heads can be combined to cover complex parts. Alternatively, wavelengths can be mixed to get the best curing properties.

Curing cycles can be activated by screen, foot pedal or PLC interface, allowing the unit to be easily incorporated into automated systems. LED heads are available in 365, 385, and 405 nm and can be used with 3-, 5-, or 8-mm diameter focusing lenses. LED heads and focusing lenses can be used in any combination and can be controlled through the system’s constant or variable mode.

In variable mode or through the 4-channel PLC interface, each LED head (up to four) can operate independently of the others. Each can be programmed in 1% increments for specific duty cycles, creating curing profiles with many advantages in a manufacturing or R&D setting. Variable mode gives users maximum curing flexibility and control over their process. Recipe storage for up to 20 programs.

Heat Control

For applications with heat-sensitive components, or exo-thermal chemistry properties, interruptions in the exposure duration can reduce the materials’ and substrates thermal rise during the cure process. This isn’t a concern with the SC-225 because each LED head can be programmed to a precise curing energy exposure profile to reduce the risk of substrate damage.

Depth of Cure vs. Surface Cure

Utilizing the multiple narrow bands available for the SC-225 the perfect combination of outputs can orchestrate the perfect cure. The approach of alternating between depth of cure and surface cure LED heads can aid in the reduction of surface tack otherwise found on single wavelength LED products.

Fluorescing for Inspection

If all four LED heads are not used during parts production, a 365 nm LED head could be set to operate as a low intensity lamp to fluoresce some Hanarey products. This aids in QC inspections, resulting in higher quality finished products.

Using the SC-225

	Capitalize on the small diameter and length of the SC-225 LED heads, as well as the short, 5-mm focus distance, to get multiple LED heads around a single point.
	Use by hand or fixtured. The heat removing design allows hand use with no PPE. The quick connects allow for easy switching of LED heads to change wavelengths in R&D applications.
	Use the 4 independently operable channels to mix wavelengths, curing times, and intensities to achieve an optimal cure. Or cure multiple pieces at one time.

Degradation/Life Testing

Unlike broad-spectrum lamps, LED curing systems do not have bulbs that require regular replacement. Instead, LED curing systems operate with high-intensity LEDs. The instant on/off functioning of LEDs greatly increases the life of these LED systems. Long-term life testing of SC-225 systems was conducted for 3,000 continuous hours at 100% intensity. As noted in the graphs below, LED degradation was found to be very low for all wavelengths and intensities. Contact Hanarey Application Engineering for additional details on setting up an LED curing process for maximum throughput and LED die life.

365 nm Emitters 100% Intensity resulted in a 8% degradation per 1,000 hours
385 nm Emitters 100% Intensity resulted in a 3% degradation per 1,000 hours
405 nm Emitters 100% Intensity resulted in a 3.1% degradation per 1,000 hours
Note: Testing conducted at 70oF +/-3°F and 10% Relative Humidity
