Tip 1: High-quality LED strips are manufactured using solder paste and reflow soldering processes, so the solder joints on the strips are smooth and not much. The shape of the solder joint is generally arc-shaped, and the amount of solder is very uniform. Such products are proven to be produced in a regular process. The cleavage joints are round or tin-tip, and the amount of solder is not uniform, indicating that it is hand-welded.
Tip 2: The FPC of the light bar has two types of rolled copper and copper. The rolled copper and the FPC are connected together, and the bending is not allowed to fall off. The copper foil on the copper plate is convex, and the connection point can be seen by the naked eye. If the bending is excessive, the pad will fall off. When purchasing, you should choose the light bar made by the rolling copper process.
Tip 3: Surface cleanliness is also an important method of purchase. The best production process for LED strips is SMT. The surface of the strips produced by SMT is extremely clean and free of any stains and impurities. And if it is not a product produced by SMT, avoid obvious cleaning marks and residual stains. If it is a handmade product, it will be even worse.
Tip 4: If the above methods are too troublesome, then use the most simple answer method to buy the well-known brand Xin Qin Lighting products. The products of well-known brands are produced by regular large-scale manufacturers. The production equipment is advanced and the production process is exquisite. All products have certificates of conformity and the supporting accessories are also perfect. Of course, it is more worry-free to use.
