1： Look at the solder joints. The LED light strips produced by legitimate LED light strip manufacturers are produced using the SMT mounting process, solder paste, and reflow soldering process.
2： Check the FPC quality. FPC is divided into two types: deposited copper and rolled copper. The copper foil of the copper plated plate is protruding, which can be seen from the connection between the solder pad and FPC upon closer inspection
3： Check the cleanliness of the surface of the LED light strip. If LED light strips are produced using the SMT process, their surface cleanliness is very good, and no impurities or stains can be seen
4： The chips and production processes used for LED lights cannot be distinguished with the eyes. It is necessary to use aging equipment and testing equipment. If you age several manufacturers' LEDs on an aging tester with high current for 24 hours or more, then measure the brightness of several manufacturers' LEDs to see which one has the smallest attenuation of luminous intensity and the quality with the smallest attenuation is the best.
