A method for manufacturing a circuit carrier for electronic components includes making available a carrier material layer made of an electrically insulating material and having at least one connecting layer which is applied at least to a first and/or second surface of the carrier material layer and has in each case a predefined layer thickness. Each connecting layer has a number of electrically conductive connections with a predefined conductor track width. At least some of the connections are strengthened by plasma spraying, at least in certain sections, with additional electrically conductive material. As a result, a greater layer thickness than the predefined layer thickness and/or a larger conductor track width than the predefined conductor track width is obtained. Furthermore, a circuit carrier for electronic components is specified.
