Because of the low barriers to entry in the production of LED light strips, many people have launched this project, which has caused uneven product quality in this industry. Then it is necessary to distinguish the quality of LED light strips and the quality of LED light strips. Do you know these 6 methods?
1. Look at the solder joints. The LED strips produced by regular LED strip manufacturers are produced by SMT patch technology, solder paste and reflow soldering process. Therefore, the solder joints on the LED 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. However, the amount of solder in the solder joints of the counterfeit version of the LED light strip is uneven, and most of the solder feet are covered by a dot, and at the same time there will be different degrees of tin tips, which is a typical phenomenon of manual soldering.
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 with 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. If the LED strips produced by the SMT process are clean, the surface is very clean, and there are no impurities and stains. However, if the counterfeit LED strip is produced by hand soldering process, no matter how it is cleaned, there will be stains and cleaning marks on the surface, and there will be flux and tin residue on the surface of the FPC.
4. Look at the packaging. Regular LED light strips will be packaged in anti-static coils, usually 5 meters per roll or 10 meters per roll, and then sealed with anti-static and moisture-proof packaging bags on the outside. The counterfeit version of the LED light belt will use recycled reel for cost saving, and then there is no anti-static and moisture-proof packaging bag. If you look carefully at the reel, you can see that there are marks and scratches left by the removal of the label on the outside.
5. Look at the label. The regular LED light belt packaging bag and reel will have printed labels instead of printed labels. The copy of the label is printed, and the specifications and parameters are not uniform.
6. Look at the attachment. The regular LED light strips will be enclosed in the packaging box with instructions for use and light strip specifications, and will also be equipped with LED light strip connectors or card holders; while the cottage version of the LED light strip packaging box does not have these accessories, because After all, some manufacturers can still save while saving.
