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:What does patch LED light mean?
Look, what's your product?. Some products have volume requirements, straight line will be relatively large, patches of small affixed to the circuit board does not occupy space, if only the light source, it may be an ordinary light bulb, as LED power saving.
Q:What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?
The main difference is the encapsulation method. The liquid silicone is mainly encapsulated and encapsulated, while the gum cake is solid and adopts a transfer molding package. Of course, there is a fundamental difference between the material, silica gel can be used for white light high-power LED, suitable for lighting. The epoxy can only be used in low-power monochrome LED, suitable for display, backlight, induction and other components.
Q:Is the forward voltage drop of the patch LED too large or too small?
If you have to be good or bad, then I can say "small" to you,Some clients have strict requirements for this
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?
Of course, the reflow soldering is generally divided into three sections of six principle of oven temperature is 150 degrees, 190 degrees, 220 degrees, with a PC lens products can not reflow soldering, PC deformation at 150 degrees, can be heated by a soldering paste on the heating plate.
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 patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
3528-60 is 60 meters per lamp, 3528 SMD lamp with no 5050 light, about 10 watts per meter. Copper wires have less resistance and may be less than 10 watts per meter.
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:Notes on patch LED
Storage bags are sealed and stored at a temperature of <40 DEG C.
Q:Patch LED beads can be bought in what place?
SMD LED lamp is now very popular, mainly because of long service life, but also rarely appear dead lights or dark, but there are many defects exist
Q:Welding method and notice of SMT LED
I recommend reflow soldering under normal conditions and manual welding only when repaired. 2 manual soldering electric soldering iron maximum power can not exceed 30W, welding temperature is controlled within 300 degrees, welding time less than 3 seconds. 3 do not touch the colloidal iron welding head. 4 when the pin is heated to 85 degrees centigrade or higher than this temperature, it can not be pressed. Otherwise, the welding will be broken.
