Aluminum foil excellent shielding effect - the signal line with 8011 cable foil


The signal line mainly refers to the line in the electrical control circuit for transmitting the sensing information and the control information. Signal lines are often a number of cable lines constitute a bundle or multiple transmission lines, can also be arranged in the printed circuit board in the printed line, with the technology and application of continuous progress, the signal line has been developed by the metal carrier for the other Carrier, such as cable. Different use of the signal line often have different industry standards, in order to facilitate the standardization of production and application.

 

When the signal line is outside the side will be a layer of aluminum foil, generally used as a signal line of the wire aluminum foil, used to reduce the external signal-free signal transmission interference; cable foil is the use of aluminum foil sealing and shielding, single or double After the plastic film, the composition of the aluminum # plastic composite foil, used as a cable shield. Cable foil requires surface with less oil, no holes, with high mechanical properties, the overall quality requirements are not high, but the length requirements are extremely strict.

Cable foil can generally use 1235-O aluminum foil and 8011-O aluminum foil, 8011 alloy thickness of 0.1, mm0.15mm or 0.2mm, 1235 alloy thickness: 0.025-0.05mm, width of 500mm, the length is required , The domestic commonly used for 2050m or 3050mm export is basically more than 4000mm.
