LED？ How to tell the difference between good and bad lighting?
1, look at the solder joints. LED strip produced by a regular LED strip manufacturer is produced by SMT, solder paste and reflow soldering. Therefore, the solder joint on the LED lamp strip is smooth, and the amount of solder is not large, and the solder joint extends from the FPC pad to the LED electrode in an arc shape. However, the amount of solder in the LED strip solder joint of the cottage version is uneven, most of them are wrapped in one point, and there will be different degrees of tin tips, which is a typical manual welding phenomenon.
2. Look at the quality of FPC. FPC is divided into two types: copper clad copper and rolled copper. The copper foil coated with copper is prominent. If you look carefully, you can see it from the connection between the pad and FPC. Calendered copper is closely combined with FPC, which can be bent at will without dropping the pad. If the copper clad laminate is bent too much, the pad will fall off and the temperature will be too high during maintenance.
3. Look at the cleanliness of LED strip's surface. If LED strip produced by SMT technology, its surface cleanliness is not good, and no impurities and stains can be seen. However, if it is hand-welded and produced in LED strip, no matter how it is cleaned, there will be stains and traces of cleaning, and there will be flux and tin slag on the FPC surface.
4. Look at the packaging. Regular LED strip will be packed with antistatic reels, usually 5 meters or 10 meters, and then the outside will be sealed with antistatic and moisture-proof packaging bags. However, the fake version of LED strip will use recycling reels to save costs, and then there is no anti-static and moisture-proof packaging bag. If you look at the scroll carefully, you can see the marks and scratches left when the label is removed.
5. Look at the label. Conventional LED strip packaging bags and reels will have printed labels instead of printed labels. The label of the shanzhai version is printed, and the specifications and parameters are not uniform.
6. Look at the attachment. Regular LED strip will attach instructions and specifications for the use of light strips in the box, and will also be equipped with LED strip connectors or card holders; These accessories are not available in the fake version of LED strip packaging box, because some manufacturers can save money after all.
