Therefore, the equipment that touches the product must have a good grounding device, and the table must be equipped with a good grounding device for the electronic components of the table during work. The tip of the electric soldering iron must be a good grounding device. It is recommended to use an air ion generating component.

　　1. Suitable cleaning method

When you use organic chemical objects to clean the overall digital tube, including LEDs, you must pay attention, because some chemicals will cause erosion and damage to the surface of the product, and will continue to cause discoloration. You can use alcohol to scrub the product and For prepreg, the specific time does not need to exceed three minutes at room temperature.

　　2, store in a suitable area

The product must be stored in a natural environment with the required temperature and environmental humidity, and it should be used within one year from the time of unpacking. If the 3-digit LED digital tube cannot be considered due to the storage regulations above, it must be stored in Baked in a natural environment at 60 degrees Celsius for more than ten hours,

　　The longer the time the general digital tube is stored in the warehouse, the more easily the surface of the commercial electrical grade is susceptible to corrosion, air oxidation or discoloration, which makes electric welding difficult. It is recommended that everyone use it as soon as possible.
