The range of green laser pointer is the irradiating distance of laser

The range of green laser pointer is the irradiating distance of laser.
Use of electromagnetic gasket shielding effectiveness of the shield a great impact. When used, should note the following:
1) All types of electromagnetic sealing gasket, which is meant to allow the reed-shaped sliding contact, never allow other types of pads or sliding contact will cause liner damage.Some green laser pointer can inherit the function of TF card
The type of liner will be exposed to excessive compression unrecoverable damaged, so limit use to set the pressure structure, to guarantee a certain amount of compression.
3) In addition to other conductive rubber pads, liners and shield the body when the electrical contacts between the good, the gasket shielding performance and there is no positive relationship between the amount of compression, increasing the amount of compression does not improve the shielding effectiveness. The range of green laser pointer is usually above 200 meters.Shielding effectiveness of conductive rubber, along with the increased amount of compression, which is conductive rubber to increase the density of conductive particles.
4) The use of liner contact with the metal plate should have sufficient stiffness, or the liner will occur under the effect of elastic deformation, the formation of new discontinuities, leading to RF leakage. For a positive compression structure, appropriate spacing of the fastening screws to prevent panel deformation.
5) size allows, try to use thicker gaskets, metal structure that allows greater processing errors, thereby reducing costs. In addition, the thicker the pad softer more generally, the rigid requirements of the small metal plate (thus avoiding the result is not due to structural deformation of two pieces of rigid due to RF leakage).
6) The liner material to be installed in locations not easily be damaged. For example, for large PSD, gaskets to be installed within the door frame, and provide some protection; for the removable panel, the best liner installed in the active panel, so remove the panel, for easy storage.
7) The range of green laser pointer depends on the power of itself. Install the liner metal surfaces must be clean, conductive, in order to ensure reliable electrical conductivity.
8) maximize the use of tank installation, tank lining and limits the role of a fixed excess compression. Use tank installation, the shield of the contact between the two parts not only through the pad to achieve full contact, but also the direct contact between the metal and therefore, has the highest shielding effectiveness.
