LED Encapsulant 5088A/B

1.Feature

5088A/B is a two components transparent liquid thermoset alicyclic epoxy resins which is developed for LED encapsulation. High Tg, long pot life, high temperature resistance and anti-UV light without yellowing. 5088A/B is wildly used in monochrome, RGB, or 3014, 3528, 5050 and other types of leadframe. The mixed (resin & hardener) viscosity can be adjusted within 600-10000 mPa S, in order to prevent different phospher from settling.

3. Recommended IFU(Clean containers and tools before use. Introduction of foreign matter may affect performance of Encapsulant)

Step	Action	Caution
1. preheating of resin	Clean the container before use, 100 aliquots of 5088A is preheated at 80°C for 40min.	Make sure container is clean
2. Mixing	120 aliquots of 5088B is added into 5088A, which is already preheated. Mix well with mixing propeller at 200rpm for 10-20 min.	A: B=100:120 (w/w) make sure proper mixing
3. Defoaming	Vacuum machine with vacuum degree at -0.1MPa is used for 2-10min until bubbles are completely removed.	Make sure there is no bubble left
4. Encapsulation	Use a dispenser to dispense. Clean the encapsulant left within the dispenser before use	Make sure there is no other foreign matter within the dispenser
5. Initial Roast	Keep holder in the oven at 120°C for 1h	Make sure there is no other Encapsulant in the oven. Timing begins after oven temeperature reachs 120°C
6. Long Time Roast	Keep holder (after initial roast) in the oven at 150 °C for another 2.5h	Make sure there is no other Encapsulant in the oven. Timing begins after oven temeperature reachs 150°C

Notes: the mixture should be used within 10h after mixing. Viscosity would rise over time, which will influence performance. Call technical service if you have any questions.

Q: Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?: If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.

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?: Epoxy resins turn yellow during short wave irradiation or long periods of high temperature, so they are very short lived when applied to high power lighting. That's why the LED lighting market is dominated by silica gel.But because of the low price of epoxy resin (silica gel and not at a level), and storage, use and processing is superior to silica gel, so the low power LED and some optical components still use epoxy resin package.

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: Patch LED light does not flash, why?: Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

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: Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?: LED high power and low power, small white rated current and LED wafer, such as a chip is 20MA two 40MA.... High power 0.5W, 100-150MA, 1W, 350MA current rating in the relevant product specifications

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: 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: The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?: The ten patch LED lamps are connected in parallel with rated power of 5 watts and voltage 3.3V.

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:
