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:What is patch LED?
Patch element. Very small, no pins, soldered directly to the circuit board. For example, the keyboard lights in a mobile phone are used in this way.
Q:Is the forward voltage drop of the patch LED too large or too small?
The pressure drop in the normal range is generally better. The smaller the pressure drop, the lower the power dissipation. The more you save the electricity bill.But not to say that the smaller the better, not in the normal range of low pressure drop products may be defective.In addition, the uniformity of the LED pressure drop is also important.
Q:What determines the brightness of the patch LED?
The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.
Q:Led lamp and Led what is the difference between the two patch! Ask for detailed explanations of the differences!
Patches do some high-end things, large luminous area, from afar to see more clearly, 5-10 meters with patches better!
Q:How does the LED patch lamp differentiate between positive and negative poles?
The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.
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:Patch LED market conditions
Patch LED (SMD LED) is mainly used in lighting systems, decoration, electronic equipment, indicators, backlight, monitors and instruments and other fields. The decline in handset and LCD TV production in 2009 could affect the supply expectations for such components.
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:Patch LED manual welding, how can welding not burn lights?
Recommend to communicate with older employees, they will have a lot of welding experience
Q:Which is good for LED patch and LED bulb?
The LED patch is the same as the LED bulbLED (light emitting diode) patch (package)The LED patch (SMD) is made of FPC circuit board, LED and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.LED bulbWith the LED patch or LED plug-in LED (light emitting diode), series or parallel, driving power supply, making a combined shell lampshade capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light.
