LED strip light is a common lighting fixture in home decoration at present. It is different from mini string light, which is often used to create an atmosphere in festivals, but LED strip light can also have a variety of choices. When we need this kind of light, we can do so.
Look at the quality of FPC
FPC has two kinds of copper clad and rolled copper. The copper foil of the copper-clad laminate is convex. The copper press is connected to the FPC, which can be bent at will, and the pad will not fall off. If the copper-clad board is bent, the pads will come off.
Look at the cleanliness of the surface of the LED linear light
The LED line light with the SMT process is very clean, and there are almost no impurities and stains on the surface. If the LED line lights are welded by hand, there will be some stains and cleaning marks on the surface.
Look at the solder joints
Generally, the LED line lamps produced by regular LED lighting manufacturers use SMT chip technology, and the LED lighting lamps use solder paste and reflow soldering technology. Therefore, the solder joints of LED line lights are very smooth, the amount of solder is small, and the solder joints are arc-shaped. However, the solder joints of inferior LED line lights are uneven, and the solder joints cover many layers of points, which affects the appearance.
