Quality identification method of customized led strip lights price
The quality identification method of customized led strip lights price, let's have a simple understanding together!
1. Look at the solder joints. The customized led strip lights price produced by the regular customized led strip lights price manufacturer is produced by the SMT patch process, with solder paste and reflow soldering. Therefore, the solder joints on the customized led strip lights price are relatively smooth and the amount of solder is not much, and the solder joints extend from the FPC pads to the LED electrodes in an arc shape.
2. Look at the quality of FPC. FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad plate is protruding. If you look closely, you can see it from the connection between the pad and the FPC. The rolled copper is closely integrated with the FPC, and can be bent arbitrarily without the phenomenon of pad falling off. If the copper-clad plate is bent too much, the pads will fall off, and if the temperature is too high during maintenance, the pads will also fall off.
3. Look at the cleanliness of the surface of customized led strip lights price. The customized led strip lights price produced by SMT process, its surface cleanliness is very good, no impurities and stains can be seen. The counterfeit version of customized led strip lights price produced by hand welding process, no matter how the surface is cleaned, there will be residual stains and traces of cleaning.
4. Look at the packaging. Regular customized led strip lights price will be packaged in anti-static reel, 5 meters per roll or 10 meters per roll, and the outside of the package is sealed with anti-static moisture-proof packaging bags. The copycat version of customized led strip lights price uses a recycled reel without anti-static and moisture-proof packaging. If you look at the reel carefully, you can see that there are traces and scratches left when the label is removed.
5. Look at the label. Regular customized led strip lights price packaging bags and reels will have printed labels, not printed labels.
