LED lights, LED lights with production because of the low barriers to entry, so there are many people on this project. However, experienced people still have the means to identify the LED strips produced by regular manufacturers and the LED strips of the cottage version (that is, the products produced by manual operation in the rental house). Regular goods and knockoffs can be seen from the appearance. Let's talk about how to identify the quality of LED strips.
Look at the packaging. The regular LED light strips will be packed in anti-static coil trays, usually 5 meters or 10 meters, and sealed with anti-static moisture-proof bags. The cottage version of the LED light strip uses recycled reel trays because of cost savings, and there is no anti-static moisture-proof packaging bag. Careful look at the reel tray can show the traces and scratches left when the label is removed.
Look at the label. Regular LED lights have printed labels on the bags and on the reels, not printed labels. The label of the cottage version is printed, and the specifications and parameters are not uniform.
see Attachment. Regular LED strips will be accompanied by instructions for use and strips in the box, as well as LED strips with connectors or decks; the cottage version of the LED strips do not have these accessories in the box.
Look at the solder joints. The LED strips produced by regular manufacturers are produced by SMT soldering process using solder paste and reflow soldering processes. Therefore, the solder joints on the LED strips are relatively smooth and the soldering amount is not large. The solder joints are arc-shaped and extend from the FPC pads to the LED electrodes. The soldering spot of the LED lamp strip of the cottage version is not uniform, and a dot is wrapped around the soldering foot, and there are different degrees of tin tips. This is a typical phenomenon of manual soldering.
Look at the quality of FPC. FPC is divided into copper and rolled copper. The copper foil of the copper plate is convex. If you look at it, you can see it from the connection between the pad and the FPC. The rolled copper is closely integrated with the FPC and can be bent freely without peeling off the pad. If the copper plate is bent too much, the pad will fall off. If the temperature is too high during maintenance, the pad will fall off.
Look at the cleanliness of the LED strip surface. The LED strips produced by the SMT process have a very clean surface and do not see any impurities or stains. If it is a cottage version of the LED lamp strip produced by the hand soldering process, no matter how the surface is cleaned, there will be traces of stains and cleaning, and there will be flux and tin residue on the surface of the FPC.
