led line light production because of the low threshold to enter, there are many companies on this project. But experienced people still have a way to identify, regular manufacturers of led line lights and copycat version of led line lights can be seen from the appearance. The following describes how to identify the quality of led line lights with your eyes.

① Look at the solder joints. LED hard track lights produced by regular manufacturers use the patch process, and are produced by solder paste and reflow welding process. Therefore, the solder joint on the LED hard track lamp is relatively smooth, and the solder paste will not be much, and the solder joint is arc shaped and extends from the FPC pad to the LED electrode. The amount of solder in the solder joint of the shanzhai version LED hard track lamp is uneven, more than a dot covers the welding foot, and there will be different degrees of tin tips, which is a typical phenomenon of manual welding.

② Look at the FPC quality. FPC is divided into two kinds of copper and calendered copper, the copper foil of the copper plate is protruding, and it can be seen from the connection between the pad and FPC. The rolled copper is closely connected with the FPC, and can be bent without falling off the pad. If the copper plate is bent too much, the pad will fall off, and the repair height will also cause the pad to fall off.

③ Look at the cleanliness of the surface. The surface cleanliness of the LED hard track lamp produced by the patch process is very high, and no impurities and stains can be seen. However, no matter how the surface of the shanzhai version of the LED hard track lamp produced by the hand welding process is cleaned, there will be traces of contamination and cleaning, and there will be flux and tin residue on the surface of the FPC.

④ Look at the packaging. Regular led line lights will be packed with anti-static coil tray, generally 5m a roll or 10m a roll, and then the outside is sealed with an anti-static moisture-proof bag. The copycat version of LED hard track lights will use recycled coil tray in order to save costs, without the use of anti-static moisture packaging bag, carefully look at the coil tray can see the appearance of the marks and scratches left by the removal of labels.

⑤ Look at the label. The regular led line light packaging bag and coil tray will have a printed label, rather than a printed label. The label of the cottage version is printed, and the specifications and parameters are not uniform.

⑥ Look at the attachment. The regular led line lights will be attached with instructions and specifications in the packaging box, and will also be equipped with led line light connectors or booths: the shanzhai version of the LED hard track light packaging box does not have these accessories. Because some manufacturers are still saving the cabin after all.
