Regular LED strip light manufacturers to produce the LED lights is the use of SMT chip technology, solder paste and reflow soldering production. Thus, LED strip light on the amount of solder joints is relatively smooth and not many joints cylindrical arc-shaped LED from the FPC to the electrode pad at the extension office. The cottage version of LED light amount of the solder joints is uneven, mostly a dot wrap fillet, and have varying degrees of tin tip appeared, which is typical of manual welding.

2, see FPC quality. FPC sub-rolled copper and copper are two kinds of Bonded Copper of copper foil is protruding, then look from the pad and the connection of FPC seen. The rolling of copper and FPC is closely connected as one, and can bend and will not appear any pad off phenomenon. Bonded Copper pad will appear if bent too much off, when the temperature is too high maintenance can also cause the pad off.
3, see the LED strip light surface cleanliness. If the SMT technology and production of LED lights, the surface cleanliness is very good, do not see any impurities and dirt. However, if the hand-welding production Knock LED strip light, no matter how clean the surface, there will be residual traces of the stain and cleaning, while the surface of the FPC will be flux residue and solder residue.
4, see the packaging. Regular LED lights will use anti-static packaging trays volume, usually 5 m or 10 m roll of a roll, and then outside and then use anti-static bag sealed moisture-proof. The cottage version of the LED strip light Equipotential Terminal Copper Busbar because of cost savings, while the use of recycled material disk volume, then there is no proof anti-static bags, a close look at the volume tray can be seen that the appearance of a clear label traces and scratches.
5, see the label. Regular LED lights and the volume of bags will have printed material above the disk label instead of printing the label. The cottage version of the label is printed, and specifications and parameters are not uniform.
6, see Annex. Regular LED lights will be attached inside the box with instructions and lamp specifications, and will be equipped LED strip light connector or deck; The cottage version of the LED strip light inside the box there is no such attachment because Some manufacturers, after all, could save the province.
