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 does patch LED light mean?
Look, what's your product?. Some products have volume requirements, straight line will be relatively large, patches of small affixed to the circuit board does not occupy space, if only the light source, it may be an ordinary light bulb, as LED power saving.
Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
Mold release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and is not soluble in contact with the chemical constituents of different resins (especially styrene and amines). Release agent also has heat and stress properties, not easy to decompose or wear; release agent bonded to the mold, and not transferred to the processed parts, without prejudice to painting or other two processing operations. Because of the rapid development of injection molding, extrusion, calendering, molding and laminating, the dosage of mould release agent is greatly improved.
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: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:What determines the brightness of the patch LED?
The current through the lamp itself. If the same lamp, so it is necessary to ensure consistency in the different current circuit, the test voltage of little significance, especially in the case of parallel lamp, current a few beads each share is not the same, some big, some small.
Q:SMD LED specification
SMD LED specification:(1) metal stent type: 0402, 0603, 0805, 1206, 3mm, 5mm, 6mm, 8mm, 10mm and so on.(2) metal support (commonly known as small butterfly) type: 2mm, 3mm and so on.(3) TOP LED (white shell) type: 1208 (30*20), 1311 (35*28), 1312 (35*32), 2220 (55*50) and so on(4) side light LED:0905 (22*12), 1105 (28*12) 1605 (40*14) and so on.
Q:Indoor full color LED display module and LED what is the difference between a full color?
Indoor full color LED display module and LED chip has three full color difference. The first part: Second: third light emitting display module: maintenance: LED full color display is not easy to maintain. LED full color patch is relatively easy to maintain.
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: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?
L electrode for eutectic solder reflow, the other can be used, regardless of the kind of welding, the temperature is not lower than 100 degrees, the flammable soluble materials have strict requirements, depending on whether the welding temperature is lower than the melting point of what you said or. Otherwise, there will be deformation or damage to the material in the reflow process.
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches 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.
