LED lamp belt production for stepped into the threshold low, but the formal manufacturers production LED lamp belt and shanzhai LED lamp belt is able to look from the exterior. 1, the solder joints. Normal leds solder joints of the belt is smooth and solder amount not much, solder joint circular arc shaped from the FPC welding plate electrode to LED in extension. The shanzhai leds with uneven solder solder volume. 2, see FPC quality. FPC divide into two kinds, apply copper and rolling of copper coated copper copper foil is out, scan it can see it from the joint of welded plate and FPC. And rolling of copper is close and FPC is an organic whole repeatedly, can be arbitrarily bent but there will be no solder falls off phenomenon. 3, look at the LED lamp belt surface cleanliness. Its surface cleanliness is very good, can't see any impurities and stain. But if use hand welding production of LED lights LED, no matter how the surface cleaning, will remain with traces of the stain and cleaning, and will help in FPC surface residual flux and tin slag. 4, see packaging. Regular LED lamp belt will use anti-static coil disc packaging, usually 5 meters a roll or 10 meters a roll, and then use anti-static moisture-proof packaging seal again outside. And other LED lights belt because of cost savings, and use recycled coil plate, then no anti-static moisture-proof packaging bags, see coil plate can see appearance with clear label and tracks when cut. 5, read labels. Regular LED lamp belt bags will be printed labels and coil plate, rather than the printed label. The shanzhai tags are printed, at the same time, do not have a unified specifications and parameters. 6, see the attachment. Regular LED lights inside the belt will be included in the enclosed instructions and lamp specification, at the same time also can equipped with leds with connector or booth; The shanzhai leds with cartons would not have these attachments, because some lamps manufacturer, after all, still can save a province.
