LED instruction manual
In order to enhance your understanding of our company's product features, it is convenient for you to grasp the use characteristics during use, to minimize or avoid unnecessary product damage or performance mismatch caused by human factors. Specifically here.
The LED BIN rating of the feed is consistent. The brightness used may vary. Different CIE BINs may use differences in the illuminating color.)
2. Packaging and storage
Avoid moisture entering the inside of the LED before unpacking. It is recommended that the SMD series of LEDs be stored in a drying cabinet with built-in desiccant. The storage temperature range is 5-30 degrees and the humidity is no more than 50%.
3. Precautions after unpacking
After the packaging is opened, take the whole volume of dehumidification measures as much as possible. Dehumidification conditions: Bake at 70 degrees for 4-12 hours.
The dehumidified material should be used as soon as possible (within 24 hours). Please leave the remaining material in an environment of 10-40 degrees and humidity not exceeding 30%.
4. Job precautions
This product can only be reflowed at most twice, and must be cooled to room temperature after the first reflow to perform a second reflow. It is recommended that the reflow temperature range is 200-240 degrees. During the operation, the material cannot be taken directly by hand, and there is sweat on the hand. The sweat has optical pollution on the surface of the silica gel, which affects the light. In addition, the silica gel is relatively soft, and the force is squeezed by the hand, which may cause the broken wire to cause a dead light.
It is not recommended to mount the LED on a curved circuit board. Avoid rapid cooling during soldering, avoid any form of mechanical force or excessive vibration during LED solder cooling, and do not bend the board after soldering. When repairing or working on a single material, the surface of the gel cannot be squeezed with tweezers. Since the silica gel is relatively soft, extruding the gel with tweezers can cause wire breakage, crushing the wafer, and severing the lamp.
In batch operation, the nozzle is smaller than the inner diameter of the product, which causes the nozzle to punch the silica gel, causing the gold wire to break and the wafer to be pressed and dead.
LEDs that have been soldered are not suitable for rework. If it is unavoidable, use a double-head soldering iron, but check if the LED characteristics are damaged after rework.
5. Electrostatic protection
LEDs are electrostatically sensitive electronic devices and should be protected against static electricity. For example: wear an electrostatic ring during use. All equipment and instruments should be grounded. It is recommended to test the assembled LED products to check if the LEDs are damaged by static electricity.
6. Cleaning and cleaning
It is recommended to use isopropyl alcohol to clean the LED. If cleaning with other solvents, make sure that the solvent does not affect the epoxy, silicone, silica gel, silver barrier, etc. Ultrasonic cleaning is not recommended to avoid damage to the LEDs. If it is unavoidable, please pre-test before cleaning to confirm whether it has adverse effects or potential hidden dangers.
7. Other considerations
Long-term exposure of the LED to sunlight or occasional exposure to UV light can cause the colloid to turn yellow.
In order to ensure the photoelectric performance of the LED, please keep the surface of the LED light-emitting area clean to avoid fingerprints or other foreign objects.
When designing the circuit, it should prevent the reverse voltage or excessive current from being instantaneously impacted on the LED during the switching process.
Avoid sharp tools such as tweezers to touch the silicone gel part during use.
