LED lights with production due to the low barriers to entry into the kind of decorative products, sales are quite a lot. Only a few experienced people have a way to identify regular manufacturers to produce LED lights with cottage version of the LED lights with (ie products produced in the rental depends on manual operations) from the appearance of a look out for. The following talk about how to identify the quality of LED lights with good or bad with eyes:

See the solder joints. Regular LED lights with LED lights with manufacturers to produce SMT chip technology, the production of solder paste and reflow process. Therefore, the LED light strip joints smooth and will not be more than the amount of solder, solder to the LED electrodes extending an arc from the FPC pads. Cottage version of LED lights with the amount of solder joints is uneven, mostly a dot wrap welding foot, and have varying degrees of icicles, which is a typical phenomenon of manual welding.

To see the quality of FPC. FPC of copper and rolled copper two Bonded Copper foil is projecting a closer look, then look out from the pad FPC connections. Rolled copper is closely connected FPC as a whole, can be bent without pad off. Bonded Copper bending too much appears the pad off, the temperature is too high can also cause maintenance pad off.

See the LED lights with surface cleanliness. If the LED lights with SMT production process, surface cleanliness is very good, do not see any impurities and stains. Hand soldering process to produce the cottage version of LED lights with the surface regardless of how the cleaning will be residual traces of stains and cleaning the surface of the FPC will be flux and dross residue.
