Ii. LED packaging is different
Resin packaging and silicone packaging. Resin packages are less expensive. Everything else is the same. Silicone packaging heat dissipation performance is good, so the price is a little more expensive than resin packaging;
Iii. Whether the LED color is consistent
At present, there are many packaging plants in China. Large and small add up to also have thousands of, of course, also have the strength of the strong and weak points. There are a lot of small packaging plants because there is no spectrophotometric separators, so either spectrophotometric separations, or is exported, so it is difficult to ensure the quality;
Iv. Differences in LED welding effects
LED welding effect: THE assembly of LED ribbon can be divided into two kinds: manual welding and machine welding. Hand welding is the use of iron, the most primitive method of welding. In this way of operation, the products are ugly in appearance, and the electrostatic maintenance measures are not good. Many LED chips are broken down, leading to the phenomenon of slightly bright or not bright when powered on. Machine welding is done by reflow welding, machine welding is not the same. Not only the welded product looks beautiful, but also the chip will not be burnt by static electricity phenomenon. At the same time, LED position and direction are more beautiful;
Five, FPC material
FPC is divided into calendering copper and copper compress two kinds. Copper clad plate is cheaper, calendered copper is more expensive;
Sixth, whether the LED lamp has patent
