LAMINATED CIRCUIT BOARD AND PRODUCTION METHOD FOR ELECTRONIC PART, AND LAMINATED ELECTRONIC PART

摘要

This invention has an object of providing a method for producing a multilayer substrate or an electronic part wherein decrease in the thickness has been enabled without causing the problem of insufficient strength or the like in the handling, as well as the electronic part. Such object has been attained by a method for producing a multilayer substrate or an electronic part comprising the steps of adhering a conductor layer to a transfer film, patterning the conductor layer to form a predetermined pattern, placing the transfer film overlaid with the patterned conductor layer on a prepreg so that the side of the conductor layer faces the prepreg, and then adhering the transfer film to the prepreg by applying heat and pressure and peeling the transfer film to produce the prepreg having the conductor layer formed thereon; and the multilayer electronic part produced by such method.
