As production we have strict test of material,half-finished,finished-products,also we take after-finished aging as one if the most important and necessary step.In the meantime our skilled and experienced workers enable a stable and reliable quality of our products.

Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?: Shunt split current series split voltageIs your single lamp voltage rated voltageIn addition to the red and green LED lights, the voltage is between 2 and 2.4, and the other colors are 3 to 3.6V

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

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?: SMD patch products basically can be used in reflow soldering, especially a little note here that the eutectic welding is the connection between the chip and the substrate support or specifically, is the bottom of the chip after completion of production of coating material and a layer of Sikkim alloy, and then set up a heating zone in solid crystal machine package in time and a temperature of about 300 degrees, the realization process of the chip at the bottom of the Sikkim alloy melt and silver plated layer connection bracket, and a clear distinction between reflow.

Q:What is patch SMD-LED?: SMD LED is the surface mount light emitting diode. It is a solid state semiconductor device that converts electricity directly into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.

Q:How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you: 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:What is the difference between patch LED beads and LED beads: General: Patch is a LED lamp, 0805, SMD beads 3014, 3528, 2835, 5050, 5630, 5730 and so on.

Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?: Mold release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and is not soluble in contact with the chemical constituents of different resins (especially styrene and amines). Release agent also has heat and stress properties, not easy to decompose or wear; release agent bonded to the mold, and not transferred to the processed parts, without prejudice to painting or other two processing operations. Because of the rapid development of injection molding, extrusion, calendering, molding and laminating, the dosage of mould release agent is greatly improved.

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:What are the storage requirements of SMT patch LED (LED)?: Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours? remove the pouch before baking, and do not open the oven door frequently

Q:What, in what way do I shunt the LED?: The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.
