1. See solder joints.
The regular LED light strip manufacturer produces the LED light strip is the use of SMT patch technology, with solder paste and reflow process production. Therefore, the LED lights on the solder point is relatively smooth and not much solder, arc-shaped solder joints from the FPC to the LED electrode extension.and Shanzhai version of the LED light solder spot welding solder uneven, more than a round point to wrap the welding feet, at the same time there will be different degrees of tin pointed, this is the typical phenomenon of manual welding.
2, look at FPC quality.
FPC is divided into copper and calendering copper two kinds, copper foil is convex out, look at the words can be seen from the connection between the pad and FPC. and Calendering copper is close and FPC connected as a whole, you can arbitrarily bend without the phenomenon of the pad off.Copper plate if bending too much will appear pad off, maintenance temperature too high will cause the pad off.
3. Look at the cleanliness of the LED light strip surface.
If the use of SMT production of LED light strips, its surface cleanliness is very good, do not see what impurities and stains.However, if the use of hand-welding technology produced by the cottage version of LED light strips, its surface no matter how clean, will remain traces of stains and cleaning, at the same time on the FPC surface will be flux and tin residue residue.
4, look at the packaging.
Regular LED light bar will be used anti-static coil packaging, generally 5.1-meter rolls or 10.1-meter rolls, and then the outside use of anti-static moisture-proof packaging bag seals.And the Shanzhai version of the LED light strip will be cost savings, and the use of recycled rolls, and then there is no anti-static moisture-proof packaging bags, carefully read the coil can see the appearance of a clear label left traces and scratches.
5, look at the label.
Regular LED light strip bags and rolls will have printed labels, not printed labels.And the Shanzhai version of the label is printed, while the specifications and parameters are not uniform.
6. See Accessories.
The regular LED light strips will be enclosed in the box with instructions and light bar specifications, and will also be equipped with LED light bar connector or card block, and the cottage version of the LED light bar box does not have these accessories, because some manufacturers are still able to save province. Learn these six to determine the quality of LED light bar method, all quality times LED light strips can not escape your discernment.
