Abstract
A method for introducing electrical insulations in a printed circuit board includes selectively introducing groove-shaped recesses between different regions of an electrically conductive layer on a substrate along a machining path using a thermal energy input such that end portions of each of the recesses or different ones of the recesses are joined to one another. The end portions are introduced parallel to one another without overlap such that a strip-shaped region of the conductive layer is initially retained between the end portions so as to insulate the different regions.
