How to distinguish between good and bad LED strip lights?

LED strip market is uneven, the price difference between regular manufacturers' products and cottage factory products is great. Suppose from the expertise to distinguish the quality of LED strip, I am afraid that many customers do not have this talent. But we can start to distinguish from the simple appearance, you can simply distinguish between good and bad quality. The following ZBL to explain how to quickly identify the good and bad of the strip!

The first can be distinguished from the following aspects.

1. Look at the solder joints

The LED strip produced by the regular LED strip manufacturer is the use of SMT SMD process, with solder paste and reflow soldering production. Therefore, the LED strip solder joints are smooth and the amount of solder will not be more, the solder joints are arc-shaped from the FPC pads to the LED electrode extension.

2. Look at the quality of FPC

FPC is divided into copper and calendered copper, copper foil is convex, if you look closely, you can see from the connection between the pad and the FPC. The calendered copper is closely and FPC is integrated, can be bent at will and will not present the pad fall phenomenon. The copper plate suppose bend too much will show the pad fall, maintenance when the temperature
The temperature is too high will also cause the pads to fall.

3. Look at the cleanliness of the surface of the LED strip

Assuming the use of SMT process LED strip, the surface cleanliness is very good, see what impurities and stains. However, assuming the use of hand soldering process of the cottage version of the LED strip, its surface no matter how to clean, there will be residual stains and cleaning traces.

4. Look at the packaging

Legitimate LED strip will choose anti-static coil packaging, generally 5 meters a volume or 10 meters a volume, and then outside the choice of anti-static moisture-proof packaging bags sealed. The cottage version of the LED strip will be because of cost savings, and the use of recycled roll material disk, and then no anti-static moisture-proof packaging bags, a closer look at the roll material disk can be seen
The surface has traces and scratches left when clearing the label.

5. Look at the label

Formal LED tape bags and rolls of material will have printed labels, not printed labels.

6. Look at the accessories

The regular LED strip will be in the box with instructions and strip specifications, together with LED strip connectors or clips; and the cottage version of the LED strip packaging box is not these accessories.
Because some manufacturers are still saving in the end.

The above is the most conventional way to identify good or bad LED strip, this is based on your LED strip is not particularly well understood in the case can use the above to judge, if you are more professional people, can be more authoritative testing to draw more accurate data conclusions.
