Application Introduction:
A bulb is composed of seven parts, of which the top is the glass cover, which is stuck on the base. There will be a hole on the base. The base is connected with the heat conduction base, the heat conduction base is connected with the radiator, the driving power supply is connected on the lamp cap, and the luminous is the lamp bead.
The highest cost of a bulb can be said to be the driving power supply. Without this driving, the lamp bead will not be on. For the quality of a bulb, the most important thing is the radiator, driving power supply and lamp beads.

Packaging:
Cautions:
The encapsulated material of the LEDs is silicone. Therefore the LEDs have a soft surface on the
Top of package. The pressure to the top surface will be influence to the reliability of the LEDs. Precautions Should be taken to avoid the strong pressure on the encapsulated part. So when use the picking up nozzle,The pressure on the silicone resin should be proper.
Soldering iron :
When hand soldering, the temperature of the iron must less than 300℃ for 3 seconds
The hand solder should be done only one times
SMT Reflow Soldering Instructions SMT :
Reflow soldering should not be done more than two times
When soldering , do not put stress on the LEDs during heating
The recommended reflow soldering profile as following
Handling Precautions :
Handle the component along the side surface by using forceps or appropriate tools
Do not directly touch or handle the silicone lens surface. It may damage the internal circuitry
Do not stack together assembled PCBs containing LEDs. Impact may scratch the silicone lens or damage the internal circuitry
