7. Reflow Soldering Requirements
Only single reflow soldering is permitted; repeated reflow is prohibited.
Leaded solder: Peak ≤230℃, max heating rate 4℃/s, soak time over 120s at 140~160℃.
Lead-free solder: Peak ≤260℃, max heating rate 4℃/s, soak time over 120s at 180~200℃.

9. Storage & Operation Guidance
Unopened reels: Store at 0~30℃, RH<60% in moisture-proof cabinet for maximum 60 days; perform first article inspection before production.
Finish all unpacked LEDs within 24 hours; bake residual LEDs at 60℃ for 12~24 hours before reuse. Never mix LEDs from different batches.
Complete reflow process right after SMT mounting with full ESD protection.
For outdoor lamp design: Apply secondary lens plus potting glue instead of direct surface encapsulation; select low oxygen permeability adhesive.
10. Application
Automotive electronics: Console button backlight, dashboard indicator, gear shift status lamp
Consumer electronics: Status indicator for home appliances, chargers and remote controls
Industrial control: Indicator lights for instruments, PLC modules and relays
Backlight field: Side light source for light guide plate and slim digital display
