Jadisi：How to identify the quality of Home led strip lights
Home led strip lights The domestic market is uneven, and the prices of products from regular manufacturers and cottage manufacturers are very different. I am afraid that many customers do not have the ability to identify the quality of Home led strip lights from a professional point of view. But we can make a preliminary appraisal from the simple appearance, and basically we can see the quality.
It can be identified from the following aspects:
- Look at the solder joints: LED strips produced by regular LED strip manufacturers are produced with SMT, solder paste, and reflow soldering. Therefore, the solder joints on the LED light bar are 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.
- Look at the quality of FPC, at the same time FPC can be divided into two types: copper plating and rolled copper. The copper foil coated with the copper plate protrudes. If you look closely, you can see it from the connection between the pad and the FPC. The calendered copper is closely connected with the FPC and can be bent at will without dropping the pad. If the copper-clad laminate is bent too much, the pad will fall off, and if the temperature is too high during maintenance, the pad will also fall off.
- Look at the cleanliness of the surface of the LED light bar: The surface of the LED light bar produced by the SMT process is very clean, and no impurities and stains can be seen. Fake LED light strips produced by hand welding, no matter how they are cleaned, there will be stains and cleaning marks on the surface.
