Compared with automatic mounting, manual stinging has one advantage, which is convenient to change different chips at any time. It is suitable for products that need to install multiple chips. 5361BS LED automatic mounting is actually a combination of two steps: gluing (dispensing) and chip installation. Firstly, silver glue (insulating glue) is applied to 5361BS LED bracket, and then 5361BS LED chip is sucked up and moved with a vacuum nozzle and placed on the corresponding bracket position. In the process of automatic mounting, it is necessary to be familiar with the equipment operation and programming, and at the same time to adjust the equipment adhesion and installation accuracy. Try to choose bakelite nozzle in the selection of nozzle, to prevent damage to the surface of 5361BS LED chip, especially the blue and green chip must use bakelite.

Machine welding is different, using SMT patch process, solder paste and reflow process production. Therefore, the solder joint on the LED lamp belt is smooth and the amount of solder is not much. The solder joint extends from the FPC pad to the LED electrode in a circular arc shape, and not only the appearance of the product after welding is beautiful (the size of the solder joint is uniform.

In order to reduce production costs, some enterprises lack safety protection devices on the circuit, which is easy to cause overvoltage and overcurrent failure, so that the LED lamp is damaged, which results in the service life of the LED lamp only less than thousands of hours. In addition, some manufacturers use leds that lose so much light that they degrade within a few months. LED light market chaos, resulting in low quality, many consumers in the use of these products, it is inevitable that LED energy-saving lamps will have doubts.

When playing mobile phones or working with computers under LED lights, you can wear a pair of anti-blue glasses to protect your eyes and block blue light from damaging your eyes. In short, although LED lighting have many advantages, but the harm of blue light contained behind it can not be ignored, we should pay attention to the harm of blue light from LED, do a good job of relevant preventive measures, so as to let our eyes reduce unnecessary harm.

From the analysis of the shape and slice morphology of the gold wire bonding, the open circuit is related to the packaging process, rather than the separation during subsequent use and welding. There is a fracture of the gold wire near the gold sphere at the inner bonding point, which causes the sample to show the characteristics of open circuit or large series resistance. It can be seen from the figure that the gold wire is fine, broken, and no overcurrent overheating characteristics, and there are no holes and other abnormalities in the potting material, indicating that the gold wire is fine because there is damage before LED potting, that is, the abnormal neck shrinkage of the sample bond wire is caused by poor bonding process control.
