SMD LED instruction manual
1. Material confirmation
Whether the grading LED BIN grades match the brightness used together may be different, and different CIE BIN may use different luminous colors together).
2. Packaging and storage
To avoid moisture entering the LED before opening the package, it is recommended that the SMD series LEDs be stored in a drying cabinet with built-in desiccant. The storage environment temperature range is 5-30 degrees, and the humidity does not exceed 50%.
3. Precautions after unpacking
After unpacking, take dehumidification measures as much as possible, dehumidification conditions: 70 degrees bake for 4-12 hours.
Dehumidified materials should be used as soon as possible (within 24 hours). The rest should be sealed or placed in an environment of 10-40 degrees and the humidity does not exceed 30%.
4. Operational precautions
This product is only re-soldered twice, and the second re-soldering can only be performed after the first re-soldering must be cooled to room temperature. The recommended reflow temperature range is 200-240 degrees. During the operation,
You can’t take the material directly by hand, there is sweat on the hand, and the sweat has optical pollution on the surface of the silica gel, which affects the light. In addition, the silicone is relatively soft, and hand squeezing will cause the wire to break and cause a dead light.
It is not recommended to mount LEDs on curved boards. Avoid rapid cooling during welding, avoid any form of mechanical force or excessive vibration during LED welding cooling,
Do not bend the board. When working on rework or single material, the surface of the colloid cannot be squeezed with tweezers, because the silicone is relatively soft, squeezing the colloid with tweezers will cause the wire to break, crush the wafer, and thus die the lamp.
In batch operation, the nozzle is smaller than the inner diameter of the product, which will cause the nozzle to stamp the silicone, causing the gold wire to break, and the wafer to be pressed and die.
The soldered LED should not be reworked, if it is inevitable, a double-ended soldering iron is used, but it is necessary to confirm in advance whether the LED characteristics will be damaged after repair.
5. ESD protection
LEDs are electrostatically sensitive electronic components, and various measures should be taken to avoid static electricity. For example, wear an electrostatic ring during use. All devices, equipment and instruments should be grounded.
It is recommended to test the assembled LED product to check whether the LED has received static damage.
6. Clean and clean
It is recommended to use isopropyl alcohol to clean the LED, if cleaning with other solvents, be sure to ensure that this solvent does not affect epoxy, silicone, silicone, bracket silver layer, etc.
Ultrasonic cleaning is not recommended to avoid damage to the LEDs. If unavoidable, pre-test before cleaning to confirm whether there are any adverse effects or potential hazards to the LED.
7. Other Considerations
Long-term exposure of LEDs to sunlight or occasional exposure to ultraviolet light may cause the colloids to turn yellow.
To ensure LED photoelectric performance, keep the surface of the LED light-emitting area clean to avoid finger prints or other foreign objects.
When designing the circuit, the reverse voltage or excessive current should be prevented from instantaneous impact on the LED during the switching process.
Avoid touching the silicone colloidal part with sharp tools such as tweezers during use.
