Neon lights shopping points

1. Look at the solder joints

The light strips produced by regular neon strip manufacturers are produced by SMT patch technology, solder paste and reflow soldering process. Therefore, the solder joints on the light strip are relatively smooth and the amount of solder is small, and the solder joints extend from the FPC pad to the neon lamp electrode in an arc shape. However, the amount of solder in the solder joints of the counterfeit version of the light strip is uneven, and most of the solder feet are covered by a dot, and there will be different degrees of tin tips, which is a typical phenomenon of manual soldering.

2. Look at the quality of FPC

FPC is divided into two types: copper and rolled copper. The copper foil of the copper-clad board is protruding. If you look closely, it can be seen from the connection between the pad and the FPC. The rolled copper is closely connected with the FPC and can be bent at will without the phenomenon of pad falling off. If the copper-clad board is bent too much, the pad will fall off, and if the temperature is too high during maintenance, the pad will fall off.

3. Look at the cleanliness of the neon light surface

If the light strip produced by SMT process is used, the cleanliness of the surface is very good, and no impurities and stains can be seen. However, if the counterfeit version of the lamp belt is produced by hand soldering, no matter how it is cleaned, there will be stains and cleaning marks on the surface, and there will be flux and tin residue on the surface of the FPC.

4. Look at the label

There will be printed labels on regular neon bags and reels instead of printed labels. The copy of the label is printed, and the specifications and parameters are not uniform.
