LED strip lights now can be regarded as one of the indispensable decoration lighting products; you need to pay attention to 6 elements when buying. Because the production of LED strip lights with low threshold, there are a lot of factories and workshops of this project which has led to LED lights market was mixed, the products quality is uneven. Person who does not have relevant knowledge and experience is easily deceived by inferior lights. But experienced people still have a way to identify, formal manufacturers LED strip lights and cottage version LED strip lights (meaning manual work products produced in the rental) can be identified from the appearance. Here we talk about how recognize good or bad quality LED strip lights:
1, solder joint. The regular production LED lights is manufactured which use SMT chip technology with solder paste and reflow processes of production. Thus, LED strip lights are relatively smooth and not many amount solder. Solder joints are a circular arc extending from the FPC LED electrode pads place. The amount of solder joints cottage version LED strip lights is uneven, mostly is a dot wrap welding foot, while there will be varying degrees of tin tip appears, which is a typical phenomenon of manual welding.
2. FPC quality. FPC has copper and rolled copper two types. Copper clad copper foil is protruding, and then looks at the FPC connector from the pad and look out. The FPC rolled copper is close and even as one can be bent and will not appear pad off phenomenon. Bonded Copper pad will appear if bent too much off, when the temperature is too high will result in the maintenance pad off.
3, tab. regular LED lights bags and roll tray above will have a printed label, instead of printing labels. The cottage version of the label is printed, and specifications and parameters are not unified.
