Tip 1: The high-quality LED light bar is manufactured using solder paste and reflow soldering process, so the solder joints on the light bar are smooth and the number is not too large. The shape of the solder joints is generally arc, and the amount of solder is very uniform. Such products are proved to be produced by formal technology. The cleavage solder joints are round or have tin tips, and the amount of solder is uneven, indicating that it is soldered by hand.
Tip 2: The FPC of the light bar has two types: rolled copper and copper-clad. The rolled copper and the FPC are connected together, so random bending will not make the pad fall off. The copper foil on the copper-clad board is protruding, and the connection point can be seen with the naked eye. If it is bent too much, the pad will fall off. When purchasing, choose a light bar made of rolled copper technology.
Tip 3: Surface cleanliness is also an important purchase method. The best production process for LED light strips is SMT. The surface of the light strips produced by SMT is extremely clean without any stains and impurities. And if it is not produced by SMT, avoid obvious cleaning marks and residual stains. It will be even worse if it is a handmade product.
Tip 4: If the above method is too troublesome for everyone, then use the simplest answer to buy the famous brand Xinqin Lighting products. The products of well-known brands are produced by regular large-scale manufacturers, with advanced production equipment and exquisite production technology. All products have qualified certificates and the supporting accessories are also very complete. Of course it is more worry-free to use.
