Application for smd 5730 led white

Production for smd 5730 led white
In fact, there is no white LED chip. White light is a blue chip, plus the phosphor to get the color. So the different white light (warm white, normal white, cold white) color temperature is not the same. After the completion of production, we will do a very detailed split. Keep the color consistent.


SMD LED Instruction Manual

Thank you for using the SMD led series products of Shenzhen Yuliang Optoelectronics Technology Co., Ltd. In order to enhance your understanding of our company's product features, to facilitate you to master its characteristics during use, to minimize or avoid the cause of human factors Necessary product damage or performance mismatch. Hereby explain.

1. Material confirmation

The LED BIN level of the input material is consistent with the brightness of the light. There may be differences in the lightness of the different CIE BINs used together.

2. Packaging and storage

Before the package is opened, moisture is prevented from entering the interior of the LED. It is recommended that the SMD series of LEDs be stored in a drying cabinet with built-in desiccant. Storage environment temperature range 5-30 degrees, humidity does not exceed 50%.

3. Preventive measures after opening the package

After unpacking, take the entire volume of dehumidification as much as possible and dehumidify at 70°C for 4-12 hours.

The dehumidified material should be used as soon as possible (within 24 hours). Remaining material should be sealed or placed in an environment with 10-40 degrees humidity and no more than 30% humidity.

4. Operational notes

This product can only be rewelded at most twice, and after the first reflow, it must be cooled to room temperature for the second reflow. It is recommended that the reflow temperature range is 200-240 degrees. During the operation process, the material can not be taken directly by hand. There is sweat on the hand and the sweat has optical contamination on the surface of the silica gel, affecting the light. In addition, the silica gel is relatively soft, and hand squeezing will cause the dead lamp to be broken.

It is not recommended to mount LEDs on a bent circuit board. Avoid rapid cooling during soldering. Avoid any kind of mechanical force or excessive vibration during LED solder cooling. After soldering, do not bend the circuit board. During rework or single-material work, the surface of the colloid cannot be squeezed with tweezers. Because the silica gel is relatively soft, pressing the colloid with a tweezer can cause wire breakage, crushing the wafer and causing the light to die.

In batch operations, the suction nozzle smaller than the inner diameter of the product will cause the nozzle to punch the silicone, causing the gold wire to break and the wafer to be pressurized and die.

It is not advisable to perform soldering on the LED that has been soldered. If it is unavoidable, double-head soldering iron should be used. However, it is necessary to confirm in advance whether the LED feature will be damaged after the repair.

5. Electrostatic protection

LEDs are electrostatically sensitive electronic devices and various measures should be taken to avoid static electricity. For example: Wear an electrostatic ring during use. All equipment and equipment should be grounded. It is recommended to test the assembled LED product to check if the LED is damaged by static electricity.

6. Clean

It is recommended that isopropyl alcohol be used to clean the LEDs. If using other solvents for cleaning, it must be ensured that this solvent will not affect the epoxy, silicone, silicone, and stent silver layers. Ultrasonic cleaning is not recommended to prevent damage to the LED. If unavoidable, please perform a pre-test in advance to confirm if there is any adverse effect on the LED or potential hazards.

7. Other notes

Long-term exposure of the LED to sunlight or occasional exposure to ultraviolet light may cause yellowing of the gel.

In order to ensure the photoelectric performance of the LED, keep the surface of the LED lighting area clean and avoid fingerprints or other foreign objects.

When designing the circuit, reverse voltage or excessive current in the switching process should be prevented from impacting the LED instantaneously.

During use, avoid sharp tools such as tweezers touching the silicone gel section.
