Product Description:

 

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:SMD LED lamp working voltage?
18 volts driven high 3030LED lamp (six core series, and 2 core, 3 core series and Design), driving power of up to 1W,1W high voltage 3030 LED (3 volts, 6 volts, 9 volts, 18 volts optional)
Q:The quality of the LED patch module
Luminous efficiency。 The LM value per watt is called luminous efficiency. This is an important criterion for judging whether LED is energy-saving or not. The incandescent lamp is about 14.4LM/W, the fluorescent lamp is about 51LM/W, the neon lamp is 43LM/W or so, and the LED is up to 150LM/W at present, but most of the LED light effects in our country are in 60~100LM/W. It should be noted that only the white light can achieve such high luminous efficiency in LED, and that red, yellow and blue are generally relatively low (mainly related to human visual definition). But compared with neon light, there is no heavy metal pollution, easy to maintain.
Q:How many volts is a single LED on the LED patch band?
3V or so, generally three, a group plus a resistor, power supply with 12V
Q:Why is the patch LED blue light dim?
The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim
Q:What does "1210" mean in patch LED?
At present, most manufacturers of SMD light strip used by 3528 and 5050, and 3535 and 5630 in the majority, there are many of the 3528 and 5050 and 3535, such as patch LED used in automotive lighting.
Q:Indoor full color LED display module and LED what is the difference between a full color?
The classification of the LED display according to the installation environment: indoor LED display screen, semi outdoor LED display, outdoor LED display; according to color: color LED screen, dual color LED display screen, LED display screen, the color LED display screen; according to the functional area can be divided into graphic screen, screen, screen, screen, digital dot matrix digital hybrid screen.
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:What is patch SMD-LED?
This really do not know how to answer you, like a sheet of the same type of solder paste used to operate, it can be said that the plug-in is not, it is patch it!
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:Notes on patch LED
Clean, do not use an unknown chemical liquid to clean the patch LED: an unknown chemical liquid may damage the patch LED. When necessary, immerse the patch LED in alcohol, less than 1 minutes at normal room temperature, and dry naturally for 15 minutes before starting to use
