2835 smd led is medium power patch super bright LED, has 0.2W 0.5W and 1W. since its size is 2.8 (length) ×3.5 (width) ×0.8 (thickness) mm, it is named 2835 smd led diode according to the method of naming the size of the LED chip substrate. Light flux 26-28 lumen smd led 2835 package is an upgraded product after 3014 led, better overall performance, more competitive in the market. The circuit board of 2835 is different from that of 3528, but it can also be replaced, with better brightness and heat dissipation than 3528. smd led 2835 is widely used on led strip light, led bars, led panel light Etc, nowadays, more manufacturers choose smd 2835 leds to produce lighting fixture.

SMT Reflow Soldering Instructions SMT


1. Reflow soldering should not be done more than two times
2. When soldering, do not put stress on the 2835 smd LEDs during heating

Soldering iron
1. When hand soldering, keep the temperature of the iron under 300℃,and at that temperature keep the time under 3 sec.
2. The hand soldering should be done only one time,

Rework
1. Customer must finish rework within 3 sec under 300℃
2. The head of iron can not touch the resin
3. Twin-head type is preferred.


CAUTIONS

Static Electricity
• Static electricity or surge voltage damages the 2835 SMD LED. It is recommended that a wrist band or an anti-electrostatic glove be used when handing the 2835 smd LED.
• A tip soldering iron is requested to be grounded, An ionizer should also be installed where risk of static.
• All devices, equipment and machinery must be properly grounded, It is recommended that measures be taken against surge voltage to the equipment that mounts the 2835 smd LED.

Heat generation
• When the 2835 smd LED are illuminating, operating current should be decided after be considering the ambient maximum temperature.
• Please consider the heat generation of the 2835 smd LED when it is designed the PCB.
• The 2835 smd LED must be mounted on metal core PCB or heat sink or applied thermal pad.

Handing LED
It recommends the following at all times when handing smd LED 2835 or assemblies containing the these LEDs:
• When handing the LED with tools like Tweezer or Nipper, do not apply Mechanical Forces directly on 2835 LED's Surface.
• Do not touch with hand LED Lens surface directly. It may contaminate the Lens surface and affect on optical characteristics.
• 2835 SMD LED should be handled from side because LED's molding material may be damaged with scratching on surface, piercing molding material and broking wire.
