As the LED competition, The different quality of Led strips are flooded in the LED Market. The high quality of LED light strips is relatively more expensive than the economy ones’. If you judge the quality of strips from the professional technology, I am afraid that not all customers are in a position to do that. However, we could identify the quality from the following points.
1. Solder Joint
Professional LED light Strip Manufacturer produce the strips with SMT Technology and Reflowing soldering machines. Therefore, the LED solder joints look smooth and nice.
2. LED Quality
LED Quality is the Top consideration of LED Light strip. many qualities are flooded with the whole led market. It has iron package, alloy wire package and gold wire package. it has something to do with the LED working life. If the LED adopt iron package, then the working life is very short but cheap is very cheap. On the contrary, Gold wire led package is best and highest, stable quality can last the LED’s working life. more than 50000 working hours.
3. FPC quality
FPC have two quality versions. one is Copper FPC and another one is Rolled Copper FPC. The Rolled Copper FPC are more expensive and the quality is better than the copper FPC. It is connected to FPC as a single entity, and it can be bent, and the solder joints still look good; so the copper foil of the sub cooper FPC is pro tuber. it could be seen from the connection between FPC and the tin plate. moreover, the Sub copper FPC are bent over much, it will cause the tin pad off.
4. Wire quality
5. Surface cleanliness
Generally speaking, The flexible strip tapes are made by SMT, the surface of strip look very good, and you don’t see any impurities and stains. However, if the strips are welding by hand, the strips will have the the mark of stains.
Normally each 5 meters LED strip light is a roll and packed in an anti-static bag. However, in order to save the cost, many factories recycle the volume reel and the strips are not packed in an anti-static bag. you could see from the volume reel the trace of stanines.
Regular Flexible LED strip light will have a printed label on the bags and roll disk instead of printing label.
