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 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.

Q:SMD LED lamp working voltage?
LED is a light emitting device of low voltage, low current, low power forward current general patch type LED when using (IF) 20MA, (VF) 1.8-2.5V, voltage of red green and blue (VF) voltage is 3.0-3.6V. Different manufacturers also have small differences, so first of all, look at the color,Of course. The multi chip assembly in high voltage chip together, some current: 1 watts, 1 watts and above. A wide variety of varieties, as follows:
Q:Which is good for LED patch and LED bulb?
Chip LEDLED patch lamp (SMD) is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.LED bulbThe light emitting diode, is capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light; LED Large Electronic = Display, LED = large electronic display; Lupus erythematosus disseminatus, systemic lupus erythematosus, a chronic idiopathic autoimmune disease; LED lead the past and past participle, meaning "leadership, led the Russian Pulkovo Airport IATA code.
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:Patch LED light broken one, short circuit can use it?
Only when a constant current source is used, the LED in series can be shorted. For the shunt power supply shunt LED, the open circuit LED can be disabled without having to manage it. The short circuit must be removed
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 patch LED?
Patch LED refers to surface mount LED.The LED is separated from the PCB board in the form of inline and surface mount. Piranha, 3mm lights, and 5mm lights are all pins. While most high-power LED is surface mount, that is, patches. Small power LED also has the form of surface mount such as PLCC-2 and PLCC-4.
Q:How does the LED patch lamp differentiate between positive and negative poles?
The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.
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 current through the lamp itself. If the same lamp, so it is necessary to ensure consistency in the different current circuit, the test voltage of little significance, especially in the case of parallel lamp, current a few beads each share is not the same, some big, some small.
Q:Patch LED light does not flash, why?
There are three main reasons:1, the temperature is too high, resulting in LED lights, dead lights.2, do not do anti-static measures, electrostatic breakdown chip, resulting in damage to the LED light.3, the use of LED lamp quality is too bad, the purchase price reasonable LED lights
