How to identify the quality of LED lamp belt

Date:Oct 11, 2018

LED Lamp Belt Market mixed, formal manufacturers of products and Shanzhai factory product prices vary greatly. If the quality of the LED lamp belt is identified from the professional technology, I am afraid many customers do not have this ability.

But we can make a preliminary identification from the simple appearance, basically can be separated from the quality of good or bad.

Mainly can be identified from the following aspects: 1, look at the solder spot. The LED lamp belt produced by the regular LED lamp belt manufacturer is made by SMT patch process, with solder paste and reflow welding.

As a result, the solder joints on the LED lamp belt are relatively smooth and the amount of solder will not be much, the solder joint is arc-shaped from the FPC pad to the LED electrode extension. 2, look at the FPC quality. The FPC is divided into two kinds of copper and calendering copper, copper foil coated copper is convex out, a closer look can be seen from the weld plate and FPC connection. and Calendering copper is closely and FPC connected as one, can be arbitrarily bent without the appearance of pad shedding phenomenon.

Copper plate if bending too much will appear pad shedding, maintenance when the temperature is too high will also cause the pad to fall off. 3. Look at the cleanliness of the LED lamp belt surface. The use of SMT process production of LED light belt, its surface cleanliness is very good, can not see any impurities and stains.

The use of hand welding process production of Shanzhai version of the LED lamp belt, its surface no matter how to clean, there will be residual stains and cleaning traces. 4, look at the packaging. Regular LED lamp belt will use anti-static coil plate packaging, 5.1-meter rolls or 10.1-meter rolls, packaging outside the use of anti-static moisture-proof packaging bag seal.

Shanzhai version of the LED lamp belt using recycled reel tray, there is no anti-static moisture-proof packaging bag, carefully look at the reel plate can see the appearance of the removal of labels left traces and scratches. 5, look at the label.

Regular LED lights with bags and reel plates will have printed labels on them, not printed labels. 6, look at the attachment.

The regular LED light belt will be attached to the box using instructions and lamp belt specifications, but also equipped with LED lamp Belt connector or card holder, and Shanzhai version of the LED lamp belt box does not have these accessories, because some manufacturers can still save the province after all.
