How To Distinguish The Quality Of LED Light Strips

- Nov 22, 2017-

LED lights with the market mixed, regular factory products and Shanzhai factory prices vary greatly. If from professional technology to identify the quality of LED lights, I am afraid many customers do not have this ability. But we can from the simple appearance to carry on the preliminary identification, basically can distinguish the quality good or bad.

Can be identified mainly from the following aspects:

1. Look at the solder joints. The LED LED lamp band produced by the regular LEDs is made with SMT patch technology, with solder paste and reflow soldering. As a result, LED lights on the spot is relatively smooth solder, solder volume will not be more, arc-shaped solder from the FPC welding plate to the LED electrode at the extension.

2, see the quality of FPC. FPC is deposited copper and calendering copper two kinds, deposited copper foil is convex, looking at the words can be seen from the connection between the pad and FPC. And the calendering of copper is closely and FPC connected as a whole, can be arbitrary bending without the phenomenon of solder disc shedding. If the bending of copper deposited too much will appear the solder plate fall off, maintenance temperature too high will cause the pad to fall off.

3, see the surface of the LED light cleaning degree. The use of SMT technology LED lamp belt, its surface cleanliness is very good, see no impurities and stains. The use of hand-welding technology production of the cottage version of LED lights, its surface no matter how clean, will be residual stains and cleaning traces.

4. Look at the package. Regular LED lights will be used in anti-static coil packaging, 5.1-meter rolls or 10.1-meter rolls, packaging outside the use of anti-static moisture-proof packaging bags sealed. The Shanzhai version of the LED lamp with recycled coil, no anti-static moisture-proof packaging bag, carefully look at the coil can see the appearance of the clear label left traces and scratches.

5, look at the label. Regular LED lights with packing bags and reel trays will have printed labels, not printed labels.

6. See appendix. The regular LED lights will be enclosed in the box with instructions and specifications, and will also be equipped with LED lights with connectors or card seats, but the Shanzhai version of the LED light box is not these accessories, because some manufacturers can save after all.
