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.
