Precautions For Use
Over-current-proof
Although the EHP-A21 series has a conductive ESD protection mechanism, customer must not use the device in reverse and should apply resistors for extra protection. Otherwise, slight voltage shifts may cause significant current change resulting in burn out failure.
1. Storage
i. ii. iii. iv. v. vi.
Do not open the moisture proof bag before the devices are ready to use. Before the package is opened, LEDs should be stored at temperatures less than 30 and humidity less than 90%. LEDs should be used within a year. After the package is opened, LEDs should be stored at temperatures less than 30and humidity less than 60%. LEDs should be used within 168 hours (7 days) after the package is opened. If the moisture absorbent material (silicone gel) has faded away or LEDs have exceeded the storage time, baking treatment should be implemented based on the following conditions: pre-curing at 605 for 24 hours.
2. Thermal Management
i.
For maintaining the high flux output and achieving reliability, EHP-A21 series LEDs should be mounted on a metal core printed circuit board (MCPCB) or other kinds of heat sink with proper thermal connection to dissipate approximately 0.5W of thermal energy at 150mA operation.
ii. iii.
Heat dissipation or thermal conduction design is strongly recommended on PCB or MCPCB for reflow soldering purposes. Please refer to soldering patterns on Page 2. Sufficient thermal management must be implemented. Otherwise, the junction temperature of die may exceed over the limit at high current driving conditions and the LEDs' lifetime may be decrease dramatically.
iv. v.
For further thermal management suggestions, please consult the Everlight Design Guide or local representatives for assistance. Special thermal designs are also recommended to take in outer heat sink design, such as FR4 PCB on Aluminum with thermal vias or FPC on Aluminum with thermal conductive adhesive, etc.
vi.
Sufficient thermal management must be conducted, or the die junction temperature will be over the limit under large electronic driving and LED lifetime will decrease critically.

3. Proper Handling
To avoid contamination of materials, damage of internal components, and shortening of LED lifetime, do not subject LEDs to conditions as those listed below.
Bare Hand Tweezers
When handling the product, do not apply direct pressure on the resin.
Do not touch the resin to avoid scratching or other damage.
Pick and Place Nozzle for Surface Mount Assembly.
During Module Assembly
Avoid directly contacting with nozzle.
Do not stack the modules together, it could damage the resin or scratch the lens.

4. Soldering Iron
i. For Reflow Process
a. EHP-A21 series are suitable for SMT process. b. Curing of glue in oven according to standard operation flow processes.
c. Reflow soldering should not be done more than twice. d. In soldering process, stress on the LEDs during heating should be avoided. e. After soldering, do not warp the circuit board.
ii. For Manual Soldering Process
a. For prototype builds or small series production runs it is possible to place and solder the LED by hand. b. Dispense thermal conductive glue or grease on the substrates and follow its curing specifications. Gently press LED housing to closely connect LED and substrate. c. It is recommended to hand solder the leads with a solder tip temperature of 280C for less than 3 second, at a time with a soldering iron of less than 25W. Solder at intervals of two seconds or more. d. Take caution and be aware that damaged products are often a result of improper hand soldering technique.
