Precautions For Use
1. Over-current-proof
Though EHP-C04 has conducted ESD protection mechanism, customers must not use the device in reverse and should apply resistors for extra protection. Otherwise, slight voltage shift may cause enormous current shift and burn out failure would happen.
2. Storage
i. ii. Do not open moisture proof bag before the products are ready to use. Before opening the package, the LEDs should be stored at temperature less than 30 and less and C relative humidity less than 90%. iii. iv. The LEDs should be used within a year. After opening the package, the LEDs should be stored at temperature less than 30 and relative C humidity less than 70%. v. vi. The LEDs should be used within 168 hours (7 day) after the package was opened. If the moisture absorbent material (silicone gel) has faded away or the LEDs have exceeded the storage time, baking treatment should be implemented based on the following conditions: Pre-curing at 605 C for 24 hours.
3. Thermal Management
i. For maintaining the high flux output and achieving reliability, EHP-C04 series LEDs should be mounted on a metal core printed circuit board (MCPCB), with proper thermal connection to dissipate approximately 1W to 5W of thermal energy under normal operation. ii. Sufficient thermal management must be conducted, or the die junction temperature will be over the limit under large electronic driving and LEDs lifetime will decrease critically.
4. Soldering Condition

4-2. For Reflow Process i. Lead reflow soldering temperature profile
ii. iii.
Reflow soldering should not be done more than two times. While soldering, do not put stress on the LEDs during heating. After soldering, do not warp the circuit board.
