Method of Identifying the Quality of LED Module Light Source Lamp Band Quality

LED module light source lamp bands are low due to production entry, many people participate in this project. However, some experienced people have a way to recognize that the LED lamp belt produced by regular manufacturers and the cottage version of the LED light zone (referring to the product produced by the leased indoor manual work) can be seen from the appearance at a glance. Next, take the products we leave the Rainbow LED lamp belt as an example to explain the method of identifying the quality of the LED light belt with the eyes. 1. Look at the packaging. The regular LED module light source light band is used with anti -static effects, generally 5 meters 1 or 10 meters 1 volume. In order to save costs, the cottage version of the LED light zone uses the recycling volume. There is no static moisture -proof packing bag. If you observe the volume carefully, you can see the traces and traces when the label disappear. 2. Look at the label. There are print labels on the regular LED lamp belt packaging bag and roll plate, not a printing label. The label of the plagiarism version is printed, and the specifications and parameters are not uniform. 3. Please see the attachment. The formal LED module light source light band is added in the box and the lamp belt specification book, and the LED light belt equipment connector and Kato. There are no these attachments in the cottage LED lamp belt packaging box. Because they can save. 4. Look at the welding point. The LED lamp belt produced by the regular LED light belt uses the SMT patch process, and the production of tinnum paste and reflux welding process. Therefore, the solder joints on the LED light band are relatively smooth and the amount of solder is not large. The solder joints extend from the FPC pad to the LED electrode. The welding tin volume of the welding point of the plagiarism version of the LED light zone is uneven, and the welding foot is wrapped in one more dot. At the same time, the tin head of different degrees is a typical phenomenon of hand -welded welding. 5. Look at the quality FPC. The FPC is divided into two types: copper and pressure -extended copper. The copper foil of copper plate is prominent. Take a closer look at the connection of the FPC. On the other hand, the crushing copper is closely connected to the FPC, and the phenomenon of the pad will not produce. You can bend arbitrarily. If the copper plate is curved too much, the pad will fall off. The temperature is too high during repair, and the pad will fall off. 6. LED module light source lamp band observation surface cleanliness. If the SMT is made through the LED light belt, the surface of the surface is very good, and no impurities and dirt can be seen. However, the cottage version of the LED lamp band produced by hand -welded, no matter how clean the surface is, will leave stains and cleaning marks. At the same time.
