📦 Package, Dimensions & Assembly Notes
The XL-3020SURC features a standard 3020 surface mount package (Metric 3020), measuring 3.0mm x 2.0mm with a height of 1.3mm. The product uses a water-clear epoxy resin lens suitable for high light transmission.
Assembly Guidelines:
- Soldering: Suitable for both infrared reflow and wave soldering.
- Reflow Profile (Lead-Free): Peak temp 255°C (+0/-5°C), time above 217°C should be 60-120 seconds.
- Reflow Profile (Lead): Peak temp 235°C (+5/-0°C), time above 183°C should be 60-150 seconds.
- Process: Designed for SMT automatic production (EIA standard packaging).
🤝 Sourcing & Supply Considerations
When integrating the XL-3020SURC into mass production, consider the following supply chain factors:
- Bin Selection: The datasheet specifies distinct bins for Brightness (E2-E5), Voltage (N12-7 to N12-9), and Wavelength (HR01-HR03). Verify your required color and intensity uniformity needs with your supplier before ordering.
- MSL Level: The component has a Moisture Sensitivity Level (MSL) of 3. Ensure proper dry packing storage and floor life management to prevent popcorning during reflow.
- Procurement: Always verify authenticity through official XINGLIGHT channels or authorized distributors to ensure ROHS compliance and reliability consistency.
❓ FAQ
Q: What is the MSL level of the XL-3020SURC and how does it affect storage?
A: The MSL is Level 3. This means the components can be exposed to a factory floor life of 168 hours (after opening the vacuum bag) before they must be reflowed to avoid moisture-induced damage. If not used within this time, baking is required.
Q: Can this LED be used in outdoor environments?
A: While the storage and operating temperatures (-40°C to +85°C) allow for cold and hot environments, the water-clear colloid is standard. For outdoor applications where rain or UV exposure is a factor, additional encapsulation or specific waterproofing measures are recommended.
Q: What is the difference between the Dominant Wavelength and Peak Wavelength?
A: The Peak Wavelength (Typ. 625nm) is the physical maximum emission of the spectrum. The Dominant Wavelength (620-630nm) describes the color perception of the human eye. Designers usually focus on Dominant Wavelength for color matching.
Q: What are the grading codes available for this model?
A: XINGLIGHT provides grading for Brightness (E2: 400-450mcd up to E5: 550-600mcd), Voltage (N12-7: 1.8-2.0V up to N12-9: 2.2-2.4V), and Wavelength (HR01: 615-620nm up to HR03: 625-630nm). Selecting the correct code is vital for product consistency.
Q: Is the XL-3020SURC compatible with lead-free soldering processes?
A: Yes, it is designed for both leaded and lead-free processes. For lead-free soldering, the maximum peak temperature is 255°C, and the component must withstand 2 passes of IR reflow according to the reliability test data.
