1, look at the solder joint
Professional and regular Anhui LED display production of high-quality led lights using advanced smt SMT process, and the inferior light strip is produced by reflow soldering and solder paste process.
2, look at the LED light strip surface clean
The difference between using sem process to produce light strip is mainly whether the surface of LED light strip is very clean, without obvious stains and impurities. And the inferior LED light belt, you will find that the surface is particularly dirty, and there is a special smell, make people very uncomfortable.
3, with the detection equipment to detect LED beads
You see with your eyes is difficult to see whether the LED lamp beads are high quality, so it is recommended that you use the detection equipment to detect, you can put several manufacturers of LED on the aging instrument, with the maximum current 24 hours later, which led lamp pearl light attenuation is small, that is the better LED lamp beads.
