How to choose electromagnetic shielding windows for industrial touch screens?
In order to solve the practical problems of electromagnetic compatibility. Electromagnetic shielding technology has been widely used in electromagnetic compatibility design, and the correct selection of shielding materials is one of the important contents. Electromagnetic shielding windows are window light transmission shielding devices that block electromagnetic waves, prevent electromagnetic radiation, prevent information leakage, and resist electromagnetic interference. They have rich functions. Users must reasonably select electromagnetic shielding window varieties according to specific technical requirements, equipment structure characteristics, application environment, etc. Solve the window shielding problem.
High-quality electromagnetic shielding windows must have two performance characteristics at the same time: one is good shielding performance, and the other is good visual effect.
Electromagnetic shielding windows can be divided into ITO conductive shielding, conductive grid shielding, wire mesh shielding and other series according to the shielding performance, various specifications, sizes, thicknesses, etc. of the shielding medium. Float glass, tempered glass, organic polycarbonate PC, acrylic, ITO conductive film, etc. can be selected according to the needs of structural design. According to the material selection. Various window shielding materials have good shielding performance and various corresponding light transmittances, and can be selected according to specific mechanical properties and structural parameter technical requirements. Understand the effectiveness of shielding, the transmission characteristics and other performance characteristics of various shielding media such as shielding screens, ITO conductive films, conductive grids, etc.
It is the premise of choosing shielding windows.
According to the transmittance, it can be divided into the following categories: 40% high mesh 300 mesh, 250 mesh shielding mesh, medium mesh 165 mesh, 50% or more transmittance 120 mesh shielding mesh, low mesh 100 mesh, 84 mesh shielding mesh, 70% or more transmittance, etc. Wire mesh shielding windows have good high, medium and low frequency band shielding effects. Wire mesh shielding windows are mainly used for various display windows with high shielding effect requirements. The size of electromagnetic shielding windows can be made into any size, and the traditional thickness is also large, generally: 1mm/1.5mm/1.8mm/2.5mm/2.5mm/3mm/4.5mm/4.5mm/6mm/6.5mm/8mm, etc.
The shielding mesh installation edge is usually retained around the shielding window to prepare for connection with the frame and equipment to ensure the conductive continuity of the equipment. Other termination structures are also available.
