High pressure chest, LAVAL nozzle in reclaiming plate are accelerated to critical speed 700m/s, are then ejected to the inner wall of preformed groove, thus
The conductive coating 4 of 0.1mm thickness is ejected in preformed groove inner wall；Subsequent reclaiming plate continues to slide along guide rail, when moving distance with
When the length of cover board is identical, required conductive coating 4 can be completed to prepare, and form external protection；Finally tear release paper off；
Alumina particles in release paper can be scraped, melting utilizes again.
For working frequency in 12.5Ghz, the variation range of the crosstalk of adjacent differential conduct piece is 10-20db；
By the obtained connector of above-mentioned preparation process, under same working environment, crosstalk can be adjusted to 50db-
57db, this adjustment can greatly promotion signal transmission effects.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
