1. Flexible LED lights with using FPC doing assembly circuit board, SMD LED
assembly, so that the thickness of the product is only the thickness of a coin, does not occupy space; universal specifications 30cm long 18 LED, 24 pcs LED 15 LED 50cm long, 24 pieces of LED, 30 pieces of LED . There are 60cm, 80cm, different users have different specifications. And it can cut, can be arbitrarily extended luminescence is not affected. FPC soft material, can be bent, folded, winding, and will not break free to move in three-dimensional space and telescopic. Suitable for irregular and narrow space, but also because of its curved and winding can be arbitrary, any combination of a variety of patterns suitable for advertising decoration.
2. LED rigid strip light PCB hard board assembly circuit board, the LED useful SMD LED assembled also useful for assembly line LED, as needed, while the use of the different components. Fixed advantage of hard light bar is relatively easy processing and installation are relatively easy; disadvantage is not at liberty to bend, not suitable for irregular. Rigid LED Strip with SMD LEDs
18 LED 24 pieces of LED, 30 pieces of LED, 36pcs LED, 40 pcs LED variety of specifications; the DIP LED 18, 24, 36, 48 different specifications, have a positive side, also known as the Great Wall of side-emitting light bar.
LED lights with production therefore launched this project because the threshold into the low, a lot of people. But the experience still have a way to identify formal manufacturers to produce LED lights with LED lights with cottage version (meaning depends on manual work products produced in the rental) from the appearance, at a glance out.
1. See the solder joints. Regular LED lights with manufacturers to produce LED lights with SMT LED chip
technology, production of solder paste and reflow process. LED lights to bring the solder joint is relatively smooth and the amount of solder will not solder an arc to the LED at the electrode extends from FPC pads. Amount of solder joints cottage LED lights with uneven, mostly a dot wrap welding foot, at the same time there will be varying degrees of icicles, which is a typical phenomenon of manual welding.
2. See FPC quality. FPC sub copper and rolled copper two Bonded Copper foil is projecting a closer look, then look out from pad with FPC connection. Rolled copper is close and FPC as a single entity, and can be bent without pads off. Bonded Copper if bent too much appears pads off, maintenance when the temperature is too high can also cause the pads off.
3. See LED lights with the cleanliness of the surface. If the LED lights with SMT production, surface cleanliness is very good, and do not see any impurities and stains. However, if the use of hand-welding process production cottage LED lights with its surface no matter how cleaning will be residual traces of stains and cleaning, the FPC surface at the same time there will be flux and tin slag residue.
4. Look at the packaging. The regular LED lamp with trays packaging, antistatic volume generally 5 m roll or 10 meters a roll, and then the outside and then anti-static moisture-proof bags sealed. Cottage version of LED lights with cost recycling volumes trays, then no antistatic moisture-proof bags, look carefully roll trays can see the appearance of clear labels left marks and scratches.
5. Look at the label. Regular LED lights with bags and roll trays above will print labels instead of printed labels. Cottage version of the label is printed, specifications and parameters are not unified.
6. See Annex. Regular LED light strip will be enclosed inside the package instructions and lamps with specifications, while also equipped with LED lights with connector or deck; cottage version of LED lights with box without these accessories, because Some manufacturers, after all, could save the province.
