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.

Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
Packaging is for TOP series LED, that is, the type of plastic molding. The patch is based on the PCB circuit board for molding. Mold release agent is used in molding.
Q:SMD LED lamp working voltage?
Voltage range of white LED lamp: 3.0-3.4VThe pressure drop of the red LED is 2.0--2.2VThe yellow light emitting diode has a pressure drop of 1.8 - 2.0VThe green light emitting diode has a pressure drop of 3 - 3.2VThe blue light emitting diode has a pressure drop of 3.0-3.4VSMD voltage is basically the same as double lead line. Current is generally 20~60mA, and some work current can exceed 100mA.
Q:What is the difference between patch LED beads and LED beads: General
A pin of the lamp, and outside a resin cap, because the reason LED beads can spotlight cap;There is no pin on the patch and there is no resin cap outside. Because of the lack of cap, the LED patch can not be concentrated.Patch is based on small power, the shape is relatively small (usually 0.5 and 0.5W products)It's called patch because some small ones need Mounter to machine.The ordinary LED lamp, solder joints than SMD beads, now is the largest artificial welding. Regular watts count from 1-300W
Q:What determines the brightness of the patch LED?
Lamp brightness level itself, is also in the rated current situation, its brightness
Q:How do led patches measure good or bad?
The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.
Q:The quality of the LED patch module
Chip size. The larger the size of the same chip, the higher the general brightness, the stronger the bearing capacity, the higher the stability performance, of course, the price is relatively high. The size of the module chips now includes: 9MIL, 10MIL, 12MIL, 14MIL, 23MIL, and so on.
Q:What is the difference in performance between the LED plug-in and the LED patch?
No difference, because the core of the two is the same, are diode PN junction, but no packaging, the production process is a little different
Q:Led lamp and Led what is the difference between the two patch! Ask for detailed explanations of the differences!
If you take a large area light, to see that the lighting requirements, functional lighting, or lighting atmosphere, or ordinary lighting, which is to be considered, the two optical (lens) can bring you the light angle planning.
Q:LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?
L electrode for eutectic solder reflow, the other can be used, regardless of the kind of welding, the temperature is not lower than 100 degrees, the flammable soluble materials have strict requirements, depending on whether the welding temperature is lower than the melting point of what you said or. Otherwise, there will be deformation or damage to the material in the reflow process.
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
LED lights are current driven, first of all, look at your LED's IF and VF values. How much power do you have?. Make sure the current is in line with the IF and the current limit can be achieved with resistors.
