What are the electrostatic problems that arise in the production process of LED display screens and what precautions should we take? This is mainly explained from the grounding and the laying of anti-static ground wires.
First of all, from the ground; is the direct discharge of static electricity through the wire connection to the earth, this is the most direct and effective anti-static measures. Specific to do from five aspects.
a: During the production process, workers are required to wear a grounded electrostatic wristband.
b: Use low-voltage DC electric screwdrivers with a ground wire as much as possible during assembly.
c: When soldering, the soldering iron should use anti-static low-voltage thermostat iron as much as possible, and maintain good grounding.
d: Ensure that the production pull table, gluing station, aging rack and other effective grounding.
e: Requirements for the production environment to be laid copper grounding.
These five aspects are elaborated from grounding, and there are three specific points to be made regarding the embedding of anti-static grounding wires.
1. Lightning rods of factory building are generally grounded together with reinforced concrete of buildings. When a lightning strike occurs, the grounding point and the entire building will become the discharge point of high-voltage and high-current.
2. Appropriate amount of charcoal powder and industrial salt are applied in the pit to increase the soil conductivity. After filling, the ground resistance is used to measure the ground resistance. The grounding resistance should be less than 4Ω, and it should be tested at least once a year.
3. There should be at least three grounding methods for the burial method.
What the appeal says is that the LED display has made detailed analysis on the static electricity in the production process and the precautions, as well as the measures taken, are explained in detail. For LED display manufacturers in the production process these are to pay attention to, but also must master the protective measures of static electricity!
