1. Look at the solder joints: The LED light strips produced by the regular LED light strip manufacturers are produced by SMT patch technology, using solder paste and reflow soldering processes.
Second, look at the quality of FPC: FPC is divided into two types: copper and rolled copper. The copper foil of the copper-clad board is protruding. If you look closely, it can be seen from the connection between the pad and the FPC.
3. Look at the cleanliness of the surface of the LED strip: If the LED strip is produced by the SMT process, the cleanliness of the surface is very good, and no impurities and stains can be seen.
4. Look at the chips and production processes used in LED lights: you can’t tell the difference with your eyes, you need to use aging equipment and testing equipment. If you put several manufacturers’ LEDs on the aging meter and use high current to aging for 24 hours or longer Over time, you can measure the brightness of LEDs from several manufacturers to see which LED has the least attenuation in luminous intensity, and the quality with the least attenuation is the best.
