Use a low-impedance ground wire in the board design so that any ESD current can flow easily into the ground instead of flowing through other low-impedance paths of the electronics. A grounding area, preferably a ground plane, can reduce the effects of ESD, so you should turn unused areas on the board into ground planes. Keeping the signal line close to ground also reduces loop area and minimizes ESD problems caused by large loops. Multilayer boards with separate ground planes are preferable.
When board layout, sensitive electronic components are kept away from potential ESD sources such as transformers, coils, and connectors. These potential ESD sources can accumulate charge or create stray electromagnetic fields that can cause component damage. It is wise to shield coils, transformers and similar components to suppress the electromagnetic fields radiated by these components. Route a ground wire between long signal lines to reduce the loop area. By placing sensitive electronic components away from the edge of the board, ESD can accidentally damage these components; this avoids human contact and damage that can be caused by ESD. Use multilayer PCBs whenever possible: Ground planes and power planes, as well as closely spaced signal line-ground spacing, reduce common impedance and inductive coupling to double-sided PCBs 1/10 to 1/100. Try to keep each signal layer close to a power or ground plane. For high-density PCBs with components on the top and bottom surfaces, short traces, and many fill locations, consider using inner traces. Most of the signal lines, as well as the power and ground planes, are on the inner layer and are therefore similar to Faraday boxes with shielding. The anti-ESD design of the PCB can be achieved by the layered design of the PCB printed circuit board and proper layout. To achieve the desired ESD resistance, it is common to pass tests, solve problems, and retest such cycles, each of which may affect at least one PCB design. In the PCB design process, most of the design modifications can be limited to increasing or decreasing components through prediction. Adjust the PCB layout to achieve the strongest ESD range performance.
Neutralization method Neutralization method is an important measure to eliminate static electricity hazards. The electrostatic neutralization method seeks to generate charged ions in places where the electrostatic charge is dense, and neutralizes the electrostatic charge. The electrostatic neutralization method can be used to eliminate static electricity on the insulator. Electrostatic hazards can be eliminated using devices such as inductive neutralizers, high voltage neutralizers, and radiation neutralizers.
