SOLDERING • Recommended Reflow Soldering Condition(Lead-free Solder) ● Recommended Soldering Pad Pattern (単位 Unit: mm) * This LED is designed to be reflow soldered to a PCB. If dip soldered or hand soldered, Nichia will not guarantee its reliability. * Reflow soldering must not be performed more than twice. * When the LEDs are cooled from the peak reflow temperature, ensure that the cooling is performed very gradually to avoid excessive stress on the LED (e.g. causing cracks in the solder joints). Ensure that sufficient preliminary verification is performed to ensure that there are no issues...

CAUTIONS(1) Storage • The storage/packaging requirements for this LED are comparable to JEDEC Moisture Sensitivity Level (MSL) 3 or equivalent. Nichia used IPC/JEDEC STD-020 as a reference to rate the MSL of this LED. • This LED uses a package that could absorb moisture; if the package absorbs moisture and is exposed to heat during soldering, it may cause the moisture to vaporize and the package to expand and the resulting pressure may cause internal delamination. This may cause the optical characteristics to degrade. To minimize moisture absorption in storage/transit, moisture-proof aluminum...
