1, see solder joints. The regular LED lamp belt manufacturer produces the LED lamp belt is the use SMT patch craft, uses the solder paste and reflow soldering production. Therefore, the LED lamp on the solder joints are relatively smooth and not much solder, solder joints are arc-shaped from FPC solder disc to the LED electrode extension.
2, see FPC quality. FPC deposited copper and calendering copper two, copper foil is convex out, a closer look can be from the solder disc and FPC connection to see. And the calendering copper is close and FPC connected as one, can arbitrarily bend without solder disc shedding phenomenon. If the bending fold too much copper plate will appear to fall off, the maintenance temperature too high will cause the solder disc shedding.
3, see the surface of the LED lamp with cleanliness. The use of SMT technology production LED lamp belt, its surface cleanliness is very good, see no impurities and stains. The use of hand welding process production of the cottage version of the LED lamp belt, the surface of no matter how washing, will be residual stains and cleaning traces.
4, see the packaging. Regular LED lights will use anti-static coil packaging, 5.1-meter volumes or 10.1-meter volumes, packaging outside the use of anti-static moisture-proof packaging bags sealed. Shanzhai version of the LED lamp belt recycling coil, no anti-static moisture-proof packaging bags, carefully look at the coil can see the appearance of the clearance of tags left traces and scratches.
5, look at the labels. Regular LED lamps with bags and coils will have printed labels, not printed labels.
6, see the attachment. The regular LED light ribbon will be enclosed in the box with instructions and light belt specifications, but also will be equipped with LED lamp connector or card holder; The cottage version of the LED lamp with the box is not the attachment, because some manufacturers after all, still can save the province.
