How to judge the quality of led strips? It can be judged from the following 6 aspects, and the specific ones will be introduced by the Shenzhen Lighting Factory of the LED strip manufacturer in detail.
1. Look at the quality of led lights with 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, you can see it 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.
2. Look at the packaging of led lights
The 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.
3. Look at the solder joints of led lights
The LED strips produced by the regular LED strip manufacturers are produced by SMT patch technology, using 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.
4. Look at the label of the led strip
The regular LED light strip 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.
5. Look at the led lights with accessories
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; but the fake version of the LED light strip packaging box does not have these Accessories, because some manufacturers can save or save after all.
6. Look at the cleanliness of the surface of the LED strip
If the LED strip is produced by SMT process, the cleanliness of the surface is not good, and no impurities and stains can be seen. 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.
