There are many types of LED light strips. Among the dazzling light strip categories, how to choose a light strip?
The purchase of LED strips is tricky. When purchasing LED strips, you can identify the quality of the strips from the following 6 points:
1. Look at the solder joints
The light strips produced by the regular LED light strip manufacturers are produced by SMT patch technology, using solder paste and reflow soldering process. Therefore, the solder joints on the LED light strip are relatively smooth and the amount of solder will not be much, and the solder joints are semi-circular. The arc extends from the FPC pad to the LED electrode, and the solder joints of the counterfeit version of the LED strip are not uniform. Most of the solder joints are covered by a dot, and there will be different levels of tin tips. This is manual soldering. Typical phenomenon
2. 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 on the outside, while the counterfeit version of LED light strips will be recycled because of cost savings. There is no anti-static and moisture-proof packaging bag on the reel. If you look carefully at the reel, you can see that there are marks and scratches on the outside of the reel.
3. Look at the label
The regular LED light strip packaging tape and reel will have printed labels instead of printed labels, while the fake version of the label is printed, and the specifications and parameters are not uniform.
4. Look at the cleanliness of the surface of the LED strip
If the LED light strip produced by the SMT process is clean, its surface is very clean, and there are no impurities and stains. However, if the hand-soldered LED light strip is used, no matter how it is cleaned, there will be stains and cleaning marks on the surface. At the same time, there will be flux and slag residue on the surface of the FPC.
5. Look at 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. Folding without peeling off the pad. If the copper-clad board is bent too much, the pad will fall off. If the temperature is too high during maintenance, the pad will fall off.
6. See attachment
The regular LED light strips will be accompanied by instructions for use and light strip specifications in the box, and they will also be equipped with LED light strip connectors or card holders, while the cottage version of the LED light strips packaging box does not have these accessories.
