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: 0603，0805，1206，3020，3528，5050，355 what is the current and voltage of these patch LED? Please give advice!
- 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: LED light SMD LED package in what form, trouble you under the guidance of...
- The LED chip has bumps and is welded to the PCB board using FLIP CHIP to packaging technology.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.
- Q: What, in what way do I shunt the LED?
- LED lights are current driven, first of all, look at your LED's IF and VF values. How much power do you have?. Make sure the current is in line with the IF and the current limit can be achieved with resistors.
- Q: Patch LED light does not flash, why?
- Are you saying that lamp is flashing? You can check the power output, according to your standard parameters and SMD beads, lamp panel series parallel mode, calculate the power output to output power of the test, you may be wrong, power, overload, but also the effective part of you may be the circuit for power transmission is not stable or low
- Q: How to detect LED SMD beads
- Resistance voltage ordinary pointer table 1.5V in general, and some only in the high resistance file (*10K file) with 9V or 15V battery, so the pointer table to measure LeD beads to hit the highest resistance profile measurement, otherwise useless, of course, at this time the brightness is very small, can not see, can only to judge the positive and negative resistance values see.
- 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 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: The quality of the LED patch module
- Chip size. The larger the size of the same chip, the higher the general brightness, the stronger the bearing capacity, the higher the stability performance, of course, the price is relatively high. The size of the module chips now includes: 9MIL, 10MIL, 12MIL, 14MIL, 23MIL, and so on.
- Q: LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
- Packaging is for TOP series LED, that is, the type of plastic molding. The patch is based on the PCB circuit board for molding. Mold release agent is used in molding.
- 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
