The standard aluminum honeycomb ventilation panel is composed of aluminum honeycomb assembled in an extruded aluminum frame. The "waveguide" structure of the honeycomb has a high EMI shielding effect and good ventilation. The standard honeycomb hole diameter is 3.2mm, the depth is 12.7mm, tin or nickel plating can improve the screen effect and environmental resistance. The double-layer aluminum honeycomb ventilation panel is a two-layer parallel aluminum honeycomb assembly.
