Jadisi: Four points to pay attention to when customizing household LED light bars
Because of its high brightness and low energy consumption, Home led strip lights 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 light strips? Jadisi summarized four points for everyone, let’s take a look
1. Look at the solder joints
The LED light bar produced by the regular LED light bar manufacturer is produced by SMT chip technology, using solder paste and reflow soldering process. Therefore, the solder joints on the LED light bar are relatively smooth and the amount of solder is small, and 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 bar 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. This 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 light bar
If the LED light bar produced by SMT process is used, the cleanliness of the surface is very good, and no impurities and stains can be seen. However, if the counterfeit LED light bar 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 Home led strip lights 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 bar 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 traces and scratches left by the removal of the label on the outside.
