What should be paid attention to when choosing a good LED light bar

What should be paid attention to when choosing a good LED light bar The LED diffuse reflection light strips we are using now are very strong and durable, and the general shelf life is about 3 years. The premise of being strong and durable is that the corresponding systems and specifications must be strictly followed during production. The following lists the LED diffuse reflection light strips during production. Things to pay attention to. 1. Pay attention to anti-static, and it is strictly forbidden to touch the PCB board without static protection, which may cause damage to the LED diffuse reflection lamp beads. 2. Be careful not to touch the lens without gloves, which will cause fingerprints on the lens.

Affects light effects. 3. Pay attention to whether the solder paste used has expired (generally, the solder paste after opening needs to be used up within 24 hours), and the quality of the solder paste must be good. Only in this way can the service life of the LED diffuse reflection light bar be guaranteed.

4. Pay attention to the curing glue, you need to ensure that the quality of the glue must be good. It is a curing glue that can withstand high temperature. The general temperature is 70-90 degrees. Because the lamp beads will emit temperature when they are in use.

If the curing glue cannot withstand high temperature, it will cause the lens to fall off. 5. Note that the lens of the LED diffuse reflection light bar must be placed in place, and the distance between the lens and the PCB board should not be greater than 0.1mm. 6. Note that the lens of the LED diffuse reflection light bar cannot be tilted.

(The angle of inclination cannot exceed 1°C) 7. Precautions for SMT placement, the SMT placement machine must adjust the data of the lamp beads and resistors. There must be no skewing. 8. Note that the temperature of reflow soldering must be controlled reasonably, otherwise it will affect the LED lamp beads.

9. When dispensing glue, you must control the amount of glue dispensed. It cannot exceed the surface of the PCB board of the LED diffuse reflection light strip. 10. Note that the packaging must be handled under anti-static equipment.

Moreover, PE anti-static bags are used for packaging and then put into cartons.
