What are the bad anti-static measures
After years of accumulated experience, it is found that many parts of the customer’s production site did not meet the requirements. Although the customer has equipped a lot of anti-static products, they still failed to meet the production process requirements. It is for your reference to avoid recurrence of similar cases.
A kind of work shoes worn by the production workshops and superior laboratories of the microelectronics industry such as electronic semiconductor devices, electronic computers, electronic communication equipment and integrated circuits to reduce or eliminate the hazards of static electricity. Anti-static work shoes can direct static electricity from the human body to the ground. anti-static work shoes eliminate the static electricity of the human body and effectively suppress the dust generated by people walking in the clean room. It is suitable for clean workshops, laboratories, etc. of pharmaceutical factories, food factories, electronics factories, etc. The anti-static work shoes are made of PU or PVC materials, which are dissipative materials, and the soles are made of anti-static and non-slip materials, which can absorb sweat and deodorize, and can achieve anti-slip and anti-static functions. They are integrated with the upper and then reinforced on the line. It can effectively leak static electricity and form a complete anti-static system together with anti-static clothing.
Anti-static measures need to be taken. LED products must adopt certain anti-static measures during the processing and production process, such as: the workbench must be grounded, workers must wear anti-static clothing, anti-static rings, and anti-static gloves, etc., conditional Anti-static ion fans can be installed, and the humidity of the workshop must be about 65%, so as to prevent the air from being too dry to generate static electricity, especially the green LED is relatively easy to be damaged by static electricity. In addition, the antistatic ability of LEDs of different quality grades is different, and the antistatic ability of high-quality LEDs is stronger. It should be noted that the increase in temperature will reduce the internal resistance of the LED. When the external environment temperature rises, the internal resistance of the LED light source will decrease. If a stabilized power supply is used for power supply, the operating current of the LED will increase. When it exceeds its rated operating current , It will affect the service life of LED products, and seriously cause the LED light source to "burn out". Therefore, it is best to choose a constant current source for power supply to ensure that the operating current of the LED is not affected by the external temperature. Sealing of LED products No matter what LED products are, as long as they are used outdoors, they are faced with waterproof and moisture-proof sealing problems. If they are not handled well, they will directly affect the service life of LED products. At present, a small number of manufacturers with relatively high product quality requirements use the traditional epoxy resin "pouring" method to seal LED products. This method is more troublesome to operate. For larger LED products (such as LED guardrail lights) If it is not very suitable, it will increase the weight of the product.
