 3. Precautions for use
   3.1  Soldering
        SMD LED encapsulation is very flexible, outside force easily demolish radiant surface and plastic, As soldering , Please handle with care!
    a. With No-clean Flux, according to reflow soldering cure condition when soldering, Reflow soldering should not be done more than two times, simultaneity you must insure clean on the radiant surface. Otherwise, foreign objects can affect radiant color.
    b. Don’t process manual soldering except repair. Recommended to be soldered with 25W Anti-static iron, The temp. of the iron should be lower than 300℃ and soldering time should not be done more than three seconds, at the same time iron can’t touch radiant surface and plastic.
    c. Don’t twist LED in course of manual soldering and experiment, Otherwise, the lights will not work possibly.
    d. Please use the same BIN grade in one panel, and don’t mix the difference BIN grade in one panel when soldering. Otherwise, it will cause a serious uneven color problem.
    e. Please control the sulfur content of solder paste and PCB.
    f.  Pb-free solder temp.-time profile as below:260℃Max.

   3.2  Cleaning
    a. Don’t be cleaned with ultrasonic. Recommended to be wiped with isopropyl alcohol or pure alcohol, wiping time should not be more than one minute. LED must be placed at room temperature for fifteen minutes before producing .you must insure clean on the radiant surface. Otherwise, foreign objects can affect radiant color.
    b. LED can’t be in contact with acetate、trichloroethylene,acetone、sulfur、nitride、acid、alkali、salt.These matters can destroy LED.

   3.3 Sealing
    a. Sealing glue can’t contain sulfur,because these matter can affect fluorescence powder poisoning.
    b. When using normal sealing glue, recommended will be operated life for 168hrs under normal temperature.
   3.4 Storage
    a. Don’t open the moisture proof bag before ready to use the LEDs.
    b. The LEDs should be kept at 30℃ or less and 60%RH or less before opening the package. The max. period before opening the package is 1 year.
    c. After opening the package, the LEDs should be kept at 30-35%RH or less, and it should be used within 3 days. If the LEDs should be kept at 30-35%RH or more, and it should be used within 4 hours.
    d. If the LEDs be kept over the conditions of 20%, baking is required before mounting. Baking
 condition as below: 70±5℃ for 12 hours for bulk goods, 105±5℃ for 1 hours for roll goods.

    e. The environment have no acid、alkali、corrosive gas、intensively shake and high magnetic field.
   3.5 Static
    a. Static and Peak surge voltage can destroy LED, Avoiding Instantaneous voltage when turn on or turn off the lights.
    b. Please wear Anti-static wrist band、Anti-static glove、Anti-static shoes in the course of operation, and the equipment must be grounded.
    c. After LED is be destroyed, leakage current increase obviously, and it will be forward voltage falling or failure lamp in the case of low current.
   3.6 Test
    a. Customer must apply the current limiting resistor in the circuit so as to drive the LEDs within the rated current. Otherwise slight voltage shift maybe will cause big current change and burn out will happen.
    b. Also, caution should be taken not to overload the LEDs with instantaneous high voltage at the turning ON and OFF of the circuit.

    c. The reverse voltage mustn’t exceed 5v when lighting on or testing the LED,otherwise, LEDs will be damaged.

   3.7 Else

    Radiant color of LEDs will be a little change with the current, recommended that LED is be used in series and resistance, when lighting, please don’t see directly radiant surface of LED, otherwise LED will burn eyes.high efficiency 2835 light emitting diode LED

Q:Welding method and notice of SMT LED
It is best to use a hot-air gun heat transfer high air volume adjustable low moment welding, the specific heat jump to the appropriate place to see what you use what kind of welding wire, welding wire of different because of the different melting point impurities also some differences. The air volume is too high, easy to blow the original
Q:Patch LED features
The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
Q:Patch LED manual welding, how can welding not burn lights?
When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.
Q:Why is the patch LED blue light dim?
If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.
Q:What does "1210" mean in patch LED?
1210 refers to the lamp specifications.LED common lamp specifications and parameters of patch0603, 0805, 1210, 3528, 5050 refers to the LED lamp belt, often used in light-emitting components ----LED size (English / Metric) name, for example, 0603 refers to the length of 0.06 inches, width of 0.03 inches. But note that the 3528 and 5050 units are metric
Q:Indoor full color LED display module and LED what is the difference between a full color?
Indoor full color LED display module and LED chip has three full color difference. The first part: Second: third light emitting display module: maintenance: LED full color display is not easy to maintain. LED full color patch is relatively easy to maintain.
Q:What is patch LED?
LED lights, a common model, has 34654635285050 piranha.The most common assembly of lights and PCB boards is the DIP, that is, dual in line and SMT surface mount technology two.The 346546 is the LED with two positive and negative pins, which are inserted into the PCB board after cutting the foot;3528 and 5050 are a cube with 3 LED lights inside, known as the "three in one" LED lamp. It has no pin underneath, but has a metal patch that can be passed through the reflow soldering machine through the solder to the PCB board.General indoor LED screen with more patches, outdoor screen with more pins.
Q:Patch LED beads can be bought in what place?
If you don't want to constantly change with it, suggest you go to OSRAM, Nichia, Corey, Taiwan Tongjia enterprise authorized agency purchase.
Q:What determines the brightness of the patch LED?
The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.
Q:Notes on patch LED
Clean, do not use an unknown chemical liquid to clean the patch LED: an unknown chemical liquid may damage the patch LED. When necessary, immerse the patch LED in alcohol, less than 1 minutes at normal room temperature, and dry naturally for 15 minutes before starting to use
