1).High quality warm white chip 2835 smd led 0.2w the vertical structure: Chip direct conduction fins to improve the heat dissipation performance, which can withstand the higher current (40-60mA)
2).Large heat sink: larger than 3528,3014 heat sink 2-3 times, excellent heat dissipation design, light decay of LED chip life more secure
3).Oversized light-emitting surface: to improve the rate of light: up to 90%.
4).Ultra-thin structure: to solve the 3528,3014 been long-standing problem spot;
5).High optical efficiency: higher than 3528,3014 luminous efficiency 2-3 times the luminous efficiency of up to 90-100LM / W;
6).Super stability: low light fades material, process, process maturity and stability.
7). The high cost: to achieve the same luminous flux, than 3528,3014 costs reduced more than 20%

Refer to Temperature-profile
After reflow soldering rapid cooling should be avoided
Temperature-profile(Surface of circuit board)
Use the following conditions shown in the figure.
<Pb-free solder> <Lead solder>
1.Reflow soldering should not be done more than two times
2.When soldering,do not put stress on the LEDs during heating

4000pcs/reel, each reel Anti-static vacuum Bag
Shipped in 3-5 days after payment
Number of reflow process shall be less than 2 times and cooling process to normal temperature is required between first and Second soldering process.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.All devices, equipment and machinery must be properly grounded.Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower, or the LEDs do not light at the low current. Criteria : (VF > 2.0V at IF=0.5mA)
3)Moisture Proof Package
It is recommended that moisture proof package be used .
Before opening the package ,The LEDs should be kept at 30°C or less and 70%RH or less. The LEDs should be used within a year.
5)After opening the package, The LEDs should be soldered within 24 hours (1days) after opening the package.
