Method of manufacturing physical structure for high frequency signal transmission
A method for fabricating a sandwiched structure of silver-copper-silver functioning as a high frequency signal transmission structure includes an insulating sheet and a conductive circuit on the insulating sheet. The conductive circuit includes a silver conductive layer bonded to the insulating sheet, a copper conductive layer formed on the silver conductive layer, and a silver covering layer laid to cover top and side surfaces of the copper conductive layer. The silver conductive layer and the silver covering layer together enclose the copper conductive layer and the higher conductivity of the silver together with the skin effect improves high-frequency transmission efficiency of the copper.
