How To Identify The Material Difference Between The Neon LED Strip

How to identify the material difference between the Neon LED Strip
In the industry where the fish is mixed with the fishworms, how to identify the quality of the Neon LED Strip is the most concerned about the needs of users, light Puda as a Neon LED Strip industry "leader" with professional knowledge to teach them how Fast and accurate, quickly identify the quality of neon lights LED light bar.
Neon LED Strip is the Neon LED Strip assembled in the ribbon of the FPC or PCB hard board, all over the use of all walks of life.Therefore, in the purchase of Neon LED Strip when you can choose to the quality of the Neon LED Strip appears to be Very tight. Neon LED Strip there are two, one is flexible LED, the other is the LED light bar.
First, the flexible Neon LED Strip is to adopt FPC to do assembly circuit board, with SMD LED assembly, so that the thickness of the product is only a coin thickness, no space; wide specifications are 30cm long 18 LED, 24 LED And 50cm long 15 LED, 24 LED, 30 LED and so on. There are 60cm, 80cm, etc., different users have different specifications. And can be arbitrarily cut, can also be arbitrarily extended and light will not be affected. The FPC material is soft, can be bent, folded, winding, can be moved in three-dimensional space and telescopic and not broken. Appropriate in the irregular place and space for the use of small places, but also because of its arbitrary bending and winding, properly in the confession of any combination of various patterns.
Second, the LED hard light bar is to use PCB hard board to do assembly circuit board, LED useful patch LED assembly, but also useful in-line LED assembly, depending on the necessary differences and the use of different components. The light is easy to solid, processing and placement are more convenient; shortcomings are not free to bend, not when the rules of the premises. Hard light with patch LED has 18 LED, 24 LED, 30 LED, 36 LED, 40 LED, etc., with a number of specifications; with straight-through LED has 18, 24, 36, 48 and other different specifications, there are positive side, side light, also known as the Great Wall light bar.
How to identify the difference between the two differences in how to identify the quality of Neon LED Strip
Recognize a: see the solder joints. Regular Neon LED Strip produced by the Neon LED Strip is the adoption of SMT chip technology, with solder paste and reflow process produced. Therefore, the Neon LED Strip on the solder joints than the creamy and the amount of solder will not be more, the solder joint was arc-like from the FPC pad to the LED electrode extension. [And the cave version of the Neon LED Strip solder joint solder is not even, mostly a dot wrapped around the foot, while there will be different levels of tin tip show, which is a typical example of manual welding.
Identification of two: see FPC quality. FPC divided into copper and rolling copper two, copper clad copper foil is protruding, look at the point of view from the connection with the FPC to see, while the rolling copper is close and FPC even As a whole, you can bend any bend and will not show the phenomenon of falling off the tape if the over-bending will appear on the pad off the tape, the maintenance of high temperature will also cause the pad off the tape.
Identification of three: see the Neon LED Strip Overview of the degree of cleanliness. If the adoption of SMT production of Neon LED Strip, the profile of the cleanliness is very good, do not see any impurities and stains, but if the use of hand welding process Cave version Neon LED Strip, its profile no matter how cleaning, the city remains stains and cleaning of the traces, while in the FPC profile will have flux and tin residue residue.
Regular Neon LED Strip will adopt anti-static coil tray packaging, usually 5 meters a volume is about 10 meters a volume, and then the surface and then adopt the anti-static moisture-proof packaging bag sealed. And the cave version of the Neon LED Strip because of the cost savings, and adopted to accept the takeover coil tray, and then there is no anti-static moisture-proof packaging bags, carefully look at the coil to see the appearance of the label to remove the mark and scratches The
