Honeycomb ventilation board with dual functions of EMI shielding and good ventilation

Shielding ventilation board: Honeycomb cut waveguide ventilation board is mainly used at necessary ventilation openings of electronic devices, which can balance the dual functions of EMI shielding and good ventilation. According to different usage scenarios and environments for military and civilian use, it has different materials, coatings, and shapes.

standardAluminum honeycomb ventilation panelComposed of aluminum honeycomb assembled in extruded aluminum frames. The honeycomb structure with a "waveguide" shape has high EMI shielding effect and good ventilation.

The standard honeycomb hole has a diameter of 3.2mm and a depth of 12.7mm. Tin or nickel plating can improve screen efficiency and environmental resistance. The double-layer aluminum honeycomb ventilation panel is assembled with two parallel layers of aluminum honeycomb

Made in extruded aluminum frames. Each layer of honeycomb is oriented at a 90 ° angle to each other, with 3 honeycomb apertures and a thickness of. 2mm x 6.35mm for each layer, resulting in a total thickness of 12.7mm. One layer is coated

Chromates can be used for environmental protection, so double-layer aluminum honeycomb panels do not require tin plating or nickel to improve their performance.

Disadvantage: Poor physical strength.

2、 Steel and copper honeycomb ventilation panels

Steel honeycomb ventilation panels have higher physical strength than aluminum honeycomb ventilation panels and are generally used in high EMI environments. The standard honeycomb aperture is 3.2mm,

The depth is 12.7mm. The surface can be coated with tin, nickel, cadmium, etc. for environmental protection. If the equipment operates in harsh smoke environments in the wild, brass honeycomb ventilation panels should be selected.

Customers can provide drawings according to specific needs, and we can produce according to the designed drawings.

3、 Dust shielding ventilation board

Dust shielding ventilation boardIt is made of three layers of aluminum wire mesh screen sandwiched in sturdy drawn metal and assembled in a frame. The frame of a standard dust shielding ventilation board is equipped with an anti electromagnetic interference pad, which has an excellent shielding interface. Dust shielding ventilation boards are used in situations where EMI protection is required and for ventilation or inlet cooling of air filtration media. As with most standard blowers, they are fixed at the rear of the dust shield ventilation panel.

Customers can provide drawings according to specific needs, and we can produce according to the designed drawings.

4、 Ultra thin dustproof shielding ventilation board

The ultra-thin dust shielding ventilation board is composed of a medium that can filter small particles in the air inside an aluminum frame. It is very thin with a thickness of about 5mm, and has excellent dust suction, protection, and extremely low air flow restriction. The frame is equipped with anti EMI shielding pads, which have a good shielding interface. The size of the ultra-thin dust shielding ventilation board is 305X610mm. When there is excessive dust on the dust filter screen, it can be cleaned with soapy water at any time, and the performance will not be affected after drying.

5、 New type of foam metal shielding ventilation board

This is a solution to the low EMI shielding efficiency of perforated metal plates or metal wire mesh used in commercial electronic devices, while avoiding the high cost, weight, and thickness of steel ventilation waveguide windows. The prominent features of this new type of foam metal shielding ventilation board are: thin thickness, light weight, and high screen efficiency. It is a new type of shielded ventilation window made by combining foam metal and Monel wire mesh through a special process. Due to the small size of metal micropores in foamed metals, high broadband shielding and dust filtering performance can be achieved with limited thickness. The Monel wire mesh, which is pulled down on the surface, not only protects the foam metal (which has a soft texture), but also has a nickel plating layer with high magnetic permeability, which can achieve high screen effect in low-frequency magnetic fields. Therefore, this new type of product is widely used in portable computers and other situations where space, environment, screen efficiency, and weight are strictly limited.
