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.
- Q:Patch LED light does not flash, why?
- Hit the meter on the buzzer and measure the patch individually. If the flash is a patch, the light goes off.
- 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?
- Chip and stent welding methods are: eutectic welding, silver glue fixed, resin insulation and fixed silicone rubber insulation fixedWelding beads: reflow soldering, hot plate welding and manual soldering.
- Q:How do led patches measure good or bad?
- LED patch how to measure methods: use two meter meter test, red pen is positive, black pen negative, if there is "bee" sound is bad, if the light is good
- Q:What is patch SMD-LED?
- Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
- Q:Indoor full color LED display module and LED what is the difference between a full color?
- The classification of the LED display according to the installation environment: indoor LED display screen, semi outdoor LED display, outdoor LED display; according to color: color LED screen, dual color LED display screen, LED display screen, the color LED display screen; according to the functional area can be divided into graphic screen, screen, screen, screen, digital dot matrix digital hybrid screen.
- Q:How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you
- Because the LED open threshold is about 1.5-1.8V. It is possible that the voltage supplied by the digital multimeter does not activate it. So look at the sign. Patch LED (SMD LED), the green point of negative, relative to the positive.
- Q:What is the difference in performance between the LED plug-in and the LED patch?
- The same, stick pieces is an early product, stick pieces than patch mature, stick pieces of my lamp has almost can not see what changes for three years with only a patch of brightness, years have been feeling a lot of dark. I believe the quality will be good soon.
- Q:Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!
- 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:Led lamp and Led patch two what is the difference between ah, the feeling is a patch of long service life, whether or not? 5-10 meters pan area lighting lamp selection Everbright shaped or patch shape?
- 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:How many volts is a single LED on the LED patch band?
- LED patch lamp 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.
