What should I pay attention to when customizing LED strips?

Because of its high brightness and low energy consumption, LED light strips are often used in building decoration, advertising light boxes, jewelry display stands and other constant-light equipment, but what aspects should be considered when customizing LED Strips light?

1. Sehen Sie sich die Lötstellen an.

The LED light bar produced by the regular LED light bar manufacturer is produced by SMT chip technology, using solder paste and reflow soldering process. Therefore, the solder joints on the LED light bar are relatively smooth and the amount of solder is small, and the solder joints extend from the FPC pad to the LED electrode in an arc shape. However, the solder joints of the fake version of LED light bars are not uniform, and most of them appear as a dot to cover the solder feet, and at the same time there will be different degrees of tin tips, which is a typical phenomenon of manual soldering.

2. Sehen Sie sich die Qualität von FPC an.

FPC wird in zwei Typen unterteilt: Kupfer und gewalztes Kupfer. Die Kupferfolie der kupferkaschierten Platine steht hervor. Wenn Sie genau hinsehen, ist es an der Verbindung zwischen dem Pad und dem FPC zu erkennen. Das gerollte Kupfer ist eng mit dem FPC verbunden und kann beliebig gebogen werden, ohne dass das Phänomen des Pad-Abfallens auftritt. Wenn die kupferkaschierte Platine zu stark gebogen wird, fällt das Pad ab, und wenn die Temperatur während der Wartung zu hoch ist, fällt das Pad ab.

3. Sehen Sie sich die Sauberkeit der Oberfläche des LED-Streifens an.

If the LED light bar 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 LED light bar is produced by hand soldering process, 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.
