Frequently Asked Questions (FAQ)
❓ Why choose 19.6μm ultra-large particle size? Ultra-high-power packaging has thicker gel layers, and small particle phosphors easily cause uneven settling leading to color rings. The 19.6μm large particle size effectively avoids this issue. | ❓ Can it be used for SMD packaging? Not recommended. The 19.6μm particle size is too large for precise dispensing processes in small-size SMD packaging. Please select 12.5μm particle size products for SMD applications. |
❓ How does it compare to YAG-04H18? YAG-04H20 has larger particle size (19.6μm vs 17.6μm) for even more stable settling. Choose YAG-04H20 for the most demanding ultra-high-power applications. | ❓ Do you offer small-batch samples? Yes. We can provide 50–100g evaluation samples for testing and verification. |
