1. Look at the solder joints. The LED strips produced by regular LED strip manufacturers are produced by SMT patch technology, using solder paste and reflow soldering. Therefore, the solder joints on the LED light strip are relatively smooth and the amount of solder is not too much. The solder joints extend from the FPC pad to the LED electrode in an arc shape.
2. 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. The rolled copper is closely connected to the FPC and can be bent at will without the phenomenon of pad falling off. If the copper-clad board is bent too much, the pad will fall off, and if the temperature is too high during maintenance, the pad will fall off.
3. Look at the cleanliness of the surface of the LED strip. The cleanliness of the surface of the LED light strip produced by SMT process is very good, and there are no impurities and stains. The counterfeit version of the LED light strip produced by the hand-soldering process will have stains and cleaning marks on its surface no matter how it is cleaned.
4. Look at the packaging. The regular LED light strips will be packaged in anti-static coils, 5 meters per roll or 10 meters per roll, and the outside of the package will be sealed with an anti-static and moisture-proof packaging bag. The counterfeit version of the LED light belt uses a recycled reel, without an anti-static and moisture-proof packaging bag. If you look carefully at the reel, you can see that there are traces and scratches left by the removal of the label on the outside.
5. Look at the label. There will be printed labels on the regular LED light belt packaging bags and reels, not printed labels.
6. Look at the attachment. The regular LED light strip will be enclosed in the box with instructions for use and light strip specifications, and it will also be equipped with an LED light strip connector or card holder; while the fake version of the LED light strip packaging box does not have these accessories, because After all, some manufacturers can still save while saving.
