Because of its high brightness and low energy consumption, LED strip are often used in building decoration, advertising light boxes, jewelry display stands and other constant-light equipment, but what aspects should be considered when customizing LED strip light?
1. Look at the solder joints. The LED strip produced by the regular LED strip manufacturer is produced by SMT chip technology, using solder paste and reflow soldering process.Therefore, the solder joints on the LED strips are relatively smooth and the amount of solder is not too many. 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 strip is uneven, and most of them are covered by a dot, and there will be different levels of tin tips. This is a typical phenomenon of manual soldering.
2. See FPC quality. 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 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. If the LED strip produced by SMT process is used, the cleanliness of its surface is very good, and there are no impurities and stains.However, if the counterfeit LED light bar is produced by hand soldering, 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. The regular LED strips will be packaged in anti-static coils, usually 5 meters per roll or 10 meters per roll, and then sealed with anti-static moisture-proof packaging bags on the outside.The counterfeit version of the LED light strip will use recycled reel for cost saving, and then there is no anti-static and moisture-proof packaging bag. If you look closely at the reel, you can see that there are marks and marks on the outside of the reel.
