LED Light Strip Buying Guide

We can make a preliminary identification from the simple appearance of the LED strip Lights, and basically can distinguish the quality of the LED strip Lights.

Solder Joint

The LED strip Lights produced by regular LED strip Lights manufacturers are produced by SMT patch technology, solder paste and reflow soldering process. Therefore, the solder joints on the LED strip are relatively smooth and the amount of solder is not much, and the solder joints extend from the FPC pads to the LED electrodes in an arc shape. However, the amount of solder in the solder joints of the counterfeit LED strip Lights is uneven, and there is usually a dot enclosing the solder leg, and at the same time, there will be different degrees of tin tip, which is a typical phenomenon of manual soldering.


Regular LED strip Lights will be packaged in anti-static rolls, usually 5 meters or 10 meters, and then sealed with anti-static and moisture-proof packaging bags. The counterfeit version of the LED strip Lights uses recycled reels to save costs, and there is no anti-static and moisture-proof packaging bag. If you look closely at the reels, you can see the marks and scratches left when the labels were removed.


Regular LED strip packaging bags and reels will have printed labels instead of printed labels. However, the label of the counterfeit version is printed, and the specifications and parameters are not uniform.

LED Strip Light surface cleaning

If the LED strip Lights produced by SMT process is used, the surface cleanliness is very good, and no impurities and stains can be seen. However, if the counterfeit LED strip Lights produced by hand-soldering process, no matter how the surface is cleaned, there will be stains and traces of cleaning, and at the same time there will be flux and tin slag residues on the FPC surface.

FPC quality

FPC is divided into two types: copper clad and rolled copper. The copper foil of the copper clad plate is protruding. If you look closely, 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 arbitrarily without the pad falling off. If the copper-clad board is bent too much, the pads will fall off, and the temperature during maintenance will be too high to cause the pads to fall off.


Regular LED strip Lights will include instructions for use and strip Lights specifications in the packaging box and will also be equipped with LED strip Lights connectors or card holders; while counterfeit LED strip Lights do not have these accessories in the packaging box, because after all, some manufacturers can save as much as they can.
