How to identify the LED lights with

How to identify the LED lights with

12V SMD 2835 LED Strip Light
Look at packaging. Regular LED lights will use anti-static roll disc packaging, usually 5 m or 10 m roll of a roll, and then the outside and then use anti-static moisture-proof bag sealed. The cottage version of the LED lights because of the cost savings, while the use of recycled roll tray, then there is no anti-static moisture-proof bags, look carefully roll pan can see the appearance of a clear label when traces and scratches.

Look at the label. Regular LED lights with bags and roll above the disk will have a printed label instead of printing labels. The cottage version of the label is printed, as well as specifications and parameters are not unified.

see Attachment. Regular LED lights will be accompanied by instructions for use inside the box and lights with specifications, while also equipped with LED lights with connector or a deck; the cottage version of the LED lights with packing box is not these attachments, because They are able to save the province.

Look joints. LED lights with LED lights with the regular production of the manufacturer is to use SMT chip technology, with solder paste and reflow soldering process of production. Thus, LED lights bring smoother solder joints and solder amount not more, to the LED solder arcuate electrode pad extending from at FPC. The amount of solder joints cottage version of LED lights with uneven, mostly a dot wrap fillet, while there will be varying degrees of icicles appear, this is typical of manual welding.

Look FPC quality. FPC sub-two copper and rolled copper, copper-clad copper foil is projecting, and then look at the FPC from the connector pads to see it. And rolled copper is closely and FPC as a single entity that can be bent and will not appear pad off phenomenon. Bonded Copper occurs if bent too much off the pad, maintenance temperature is too high will cause the pad off.

Look LED lights belt surface cleanliness. If using SMT technology, the LED lights, surface cleanliness is very good, I do not see any impurities and stains. But if the hand-welding process to produce copycat version of LED lights, no matter how clean the surface, there will be residual traces of dirt and cleaning, while there remains in flux and dross FPC surface.
