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:Welding method and notice of SMT LED
The power of the soldering iron should not be too big. Generally choose 20--35 watt welding time as short as possible, it is best to hang the copper wire on the solder, do not use solder paste in the soldering flux, and choose the rosin as well
Q:SMD LED lamp working voltage?
Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage
Q:SMD LED specification
LED patch: 0603, 0805, 1206, 1210, 5050. The 0603: conversion to metric is 1005, that of the LED element length is 1.0mm, width is 0.5mm. The trade is abbreviated as 1005, and the English name is 0603. The 0805: conversion to metric is 2125, that of the LED element length is 2.0mm, width is referred to as the 2125 inch 1.25mm. industry, it is 0805. The 1206: conversion to metric is 3216, that of the LED element length is 3.2mm, width is 1.6mm. The trade is abbreviated as 3216, and the English name is 1206. The 1210: conversion to metric is 3528, that of the LED element length is 3.5mm, width is 2.8mm. The trade is abbreviated as 3528, and the English name is 1210. The 5050: This is a metric called, said that the LED element length is 5.0mm, width is 5.0mm. Industry abbreviation 5050
Q:How to install the patch LED lamp band?
More attention is paid to the lamp with waterproof and the installation of a solid in the outdoor installation, outdoor installation often adopts the mode of fixed card slot, need to cut and connected place, and indoor installation, just need another with waterproof glue, waterproof effect to consolidate the connection point.
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:Indoor full color LED display module and LED what is the difference between a full color?
(1): LED full color light emitting module display module is generally yellow green, pure green module price is more expensive; SMD full color LED display using pure green tube coreThe display module (2): LED full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; patch LED full color consistent, high brightness;(3): maintenance module LED full color display is not easy to maintain, the whole module replacement cost is high; SMD full-color LED screen for easy maintenance, repair and replacement of single lamp;
Q:What are the storage requirements of SMT patch LED (LED)?
Moisture-proof packing- anti SMD LED in the transport and storage of moisture absorption, SMD LED shall be placed in sealed moisture-proof bag, inside put damp proof agent for protection, and placed the humidity humidity SMD display card packaging bag.
Q:What is patch LED?
LED is usually the lead pins form, need to be drilled on the printed circuit board, the LED pin is inserted in the hole, welded with wave soldering machine; and the patch type LED is used in welding surface, flat welded on the circuit board.
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:LED light SMD LED package in what form, trouble you under the guidance of...
Draw your own line, mm is replaced by mil on the line, with vernier caliper measurement, or know the model, count the number of mil. For example, 5050 is a close square with a width of 5.0mm*5.0mmInline LED (such as straw hat lights, 5mm), piranha LED, surface mount LEDSinglechip collection from hardware to software chm
