How to identify LED lamp belt

Review: LED lamp, LED lamp belt into the production because the threshold is low, so many people on this project. But people have experience still have a way to identify, regular LED lamp manufacturer and copycat version of the LED lamp (i.e. in the rental by manual operation of the products produced) is a can come out from the appearance of the eye. Here's to our company in Dongguan Guanghong Electronics Co. Ltd. products as an example, to talk about how to identify the quality of eyes with LED lamp belt: packaging. The formal LED lamp belt will use anti-static coil packing, usually 5 meters a roll or a volume of 10 meters, and then use the anti-static moisture-proof packaging bag seal. The cottage version of the LED light will be because of the cost savings, and the use of recycled material roll, and then there is no anti static moisture-proof packaging bags, carefully look at the material can be seen when the disk has a clear label to leave traces and scratches. Label. The regular LED lamp with a bag and reel will be printed on the label, rather than the printed label. The cottage version of the label is printed, while the specifications and parameters are not uniform. See annex. LED lamp with formal will attach instructions and specifications in the lights inside the boxes, also equipped with LED lights with a connector or card holder; not the accessories and LED lamp with copycat version of the box, because they can save a province. At solder joints. LED lamp with a regular production of LED lamp belt is the use of SMT patch process, using solder paste and reflow process. As a result, the solder joints on the LED lamp belt are relatively smooth and the amount of solder is not much, and the solder joint is circular arc extending from the FPC pad to the LED electrode. The cottage version of the LED lamp with the solder solder uneven, more than a dot wrapped welding feet, while there will be varying degrees of tin tips, which is a typical phenomenon of manual welding. FPC quality. FPC deposited copper and two kinds of copper, copper foil is convex out, look at the words can be seen from the junction of the pad and FPC. The rolled copper is closely connected with the FPC, can be arbitrarily bent without the phenomenon of the pad off. If the copper plate bent too much will appear to fall off the pad, when the temperature is too high maintenance will cause the pad off. LED lamp with surface cleanliness. If the use of SMT technology to produce LED lamp belt, its surface cleanliness is very good, can not see what impurities and stains. However, if the use of hand welding process to produce the cottage version of the LED lamp belt, and its surface no matter how clean, will remain traces of traces of dirt and cleaning, while the surface of the FPC will have flux and tin residue.
