Mechanical Dimensions

1. The aluminum-core PCB features labeled electrical pads, with “+” and “-” denoting positive and negative, respectively. All positive pads and all negative pads are interconnected, which allows for flexible array configurations.
2. Drawing not to scale.
3. All dimensions are in millimeters.
4. Unless otherwise indicated, tolerances are ± 0.2 mm.
5. Avoid applying any force, impact, or pressure to the LED lens, as this will lead to catastrophic failure.
6. To ensure continuous improvement, the product’s appearance and specifications may be updated without notice.

Flux Characteristics at 700 mA, Temperature = 25 ℃

• Siro Electronics maintains a tolerance of ± 5% on flux measurements.
• To prevent damage, do not drive the device at its rated current for more than one second without an adequate heat sink.

Optical Characteristics at 700 mA, Temperature = 25 ℃

• Siro Electronics maintains a tolerance of ± 1 nm for wavelength measurements.

Electrical Characteristics at 700 mA, Temperature = 25 ℃

• Siro Electronics maintains a tolerance of ± 0.1 V for voltage measurements.

Spectral Power Distribution (SPD), Temperature = 25 ℃

Soldering Instructions

• For soldering wires to an LED on a star board, use a heat-resistant surface. Avoid soldering on an ESD mat, which could be damaged by the heat.
• Use a small chisel-type soldering tip to focus heat directly onto the pad.
• When soldering, always ensure that all surfaces are perfectly clean.
• Applying a small amount of solder flux to the pad can be beneficial.
• Prevent damage to the LED and the MCPCB’s dielectric layer. Any damage to the epoxy layer can cause a short circuit in the array.

Storage Conditions

• Store LEDs at or below 30 °C and 70% RH before opening the package.
• It is recommended that LEDs be used within one year.
• After opening the package, store LEDs in a dry box at or below 30 °C and 30% RH.

Electrostatic Discharge (ESD) Precautions

• Static electricity or surge voltage can damage ceramic LEDs. We recommend using a wrist strap or anti-static gloves when handling them.
• Ensure your soldering iron tip is grounded and install an ionizer in areas where there is a risk of static electricity.
• All devices, equipment, and machinery must be properly grounded to ensure their safe operation. Additionally, surge protection measures are recommended for equipment that mounts ceramic LEDs.

Thermal Management

• When designing your product, you must consider the LED’s heat dissipation.
• To ensure optimal performance and longevity, the LED operating current must be determined based on the maximum ambient temperature.
• Note that even with a pre-mounted aluminum PCB, heat dissipation is still a critical concern. If necessary, consider adding a heatsink or a fan.

Handing LEDs

We recommend the following guidelines for handling LEDs or assemblies containing them at all times:

• When handling LEDs with tools like tweezers or nippers, avoid applying mechanical force directly to the LED’s surface.
• Do not directly touch the LED lens surface with your hands. This may contaminate the lens and affect its optical characteristics.
• Always handle LEDs from the sides. Applying force or scratching the surface can damage the molding material or break internal wires.
