How To Identify The Quality And Brand Of Sideview LED Flexible Strip?

1, Sideview LED Flexible Strip chip: chip with domestic chip and Taiwan chip, as well as imported chips (including the US chip, the Japanese chip, the German chip, etc.). Chip different, the price difference is very large. The most expensive is the US chip, followed by the Japanese chip and the German chip, the price is moderate Taiwan chip. At present there are many domestic packaging plant, large and small plus there are thousands, of course, there is strength of the strength of the points. There are many small packaging plant because there is no split color separation machine, so either no color separation, or is outgoing, so that the quality is difficult to guarantee. No color separation of the LED, the color consistency is poor, installed in the Sideview LED Flexible Strip on the effect after the light is not so good. Regular manufacturers have sophisticated test equipment, lamp beads through strict spectral separation, consistency is good, high cost, there are other packaging materials used in different, of course, the price difference is relatively large.
2, Sideview LED Flexible Strip welding effect: Sideview LED Flexible Strip assembly sub-manual welding and machine welding two, manual welding is the use of soldering iron, using the most primitive way of welding, solder joint solder is not uniform, mostly a round Point to cover the welding feet, at the same time there will be different degrees of tin tip appears, which is a typical phenomenon of manual welding. This kind of operation out of the product is the appearance of ugly (solder joint size is inconsistent, flux residue, solder joints are not smooth, LED package is burned, etc.), the second is the static protection measures are not good, many LED chip breakdown, Resulting in power when the phenomenon of light or not bright. Machine welding is not the same, the use of SMT chip technology, with solder paste and reflow process production. As a result, the solder joints on the Sideview LED Flexible Strip are smoother and the amount of solder is not much. The solder joints extend in a circular arc shape from the FPC pad to the LED electrode. The solder product is not only beautiful (solder joint size) Point smooth, no flux residue, LED package intact), and the chip will not be the phenomenon of electrostatic burnout. At the same time, LED location and direction are more beautiful, so the processing cost difference is also great.
3, Sideview LED Flexible Strip FPC material: FPC sub-pressure copper and copper two, copper is cheaper, more expensive copper rolling. Copper plate of the pad in the bend easily fall off, and rolling copper will not. And the current for the different Sideview LED Flexible Strip manufacturers due to cost control reasons, some manufacturers will cut corners in the FPC width, to bring security risks to customers.
4, Sideview LED Flexible Strip brightness: different brightness LED prices are different, ordinary brightness and high brightness LED price difference is quite poor. Therefore, we must clearly know what kind of brightness they need, so as to accurately locate the products they need.
5, Sideview LED Flexible Strip color: different colors, the price is not the same. White, green color and color separation is more difficult, so the price is higher than the price of other colors; red, yellow, blue and other color separation is easier, and consistency is better, so the price is slightly cheaper. Special colors such as purple, pink and other color reasons, the price is the most expensive.
6, Sideview LED Flexible Strip lamp beads size: light with the market is currently used 3528 and 5050 lamp assembly, some manufacturers will use 3014 lamp beads package (3014 lamp beads brightness and power between 3528 and 5050). Different specifications of the size of the LED, the price is different. 3528,5050,3014 specifications of the LED price difference between the poor.
7, Sideview LED Flexible Strip surface cleanliness: If you use the SMT process Sideview LED Flexible Strip, the surface cleanliness is very good, do not see any impurities and stains. However, if the use of hand-welding production of the cottage Sideview LED Flexible Strip, the surface no matter how cleaning, will remain stains and cleaning traces, while the FPC surface will have flux and residual tin slag.
8, Sideview LED Flexible Strip packaging: regular Sideview LED Flexible Strip will use anti-static coil tray packaging, usually 5 meters a volume or 10 meters a roll, and then outside the use of anti-static moisture-proof packaging bag (bag Will be placed in the desiccant). While the cottage version of the Sideview LED Flexible Strip because of cost savings, and the use of recycled coil, that is, no anti-static moisture-proof packaging bags, and very save money.
