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:Patch LED beads can be bought in what place?
- If you don't want to constantly change with it, suggest you go to OSRAM, Nichia, Corey, Taiwan Tongjia enterprise authorized agency purchase.
- Q:Notes on patch LED
- Moisture proof, in order to avoid the products in the transport and storage of moisture, SMD LED packaging is moisture-proof aluminum packaging, and packaging bag containing a desiccant and humidity card, mainly to control the desiccant bag, humidity, humidity card is mainly to monitor the packaging bag of humidity
- Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?
- Table 1, contact electrostatic protection LED product should be covered with protective electric tape, and its reliable grounding; 2, personnel shall wear groundstrap in contact with LED (best for cable, protective gloves, anti-static ring) allows better wear anti-static clothing, anti-static shoes and static electricity cap; 3, the application in the process of exposure to LED equipment must be reliable grounding, such as iron, shearing machine, bending machine and welding equipment. Conditional still can install plasma fan to eliminate electrostatic; 4, in use or when designing electronic circuit, must consider the harm that excessive current has to LED
- 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:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
- They differ in form and belong to the SMDLED category. Encapsulation uses liquid silicone and epoxy resins as well. The patches are basically made of epoxy resin. Relatively speaking, the amount of liquid silica should be relatively large.
- Q:How do led patches measure good or bad?
- Use the two stage tube test of the multimeter, the red pen is connected, and the black pen is negative. If there is a bee, the sound is bad, and if the light is bright, it is good
- 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:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
- 3528-60 is 60 meters per lamp, 3528 SMD lamp with no 5050 light, about 10 watts per meter. Copper wires have less resistance and may be less than 10 watts per meter.
- 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?
- First of all, I want to say, in the same light emitting chip case, two is not what were, just a different process is a DIP plugin, a SMD patch process, the 3 floor of the right, just some high grade patch.
- Q:Patch LED features
- The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
