Abstract
In a printed circuit board (10), in which at least one signal conductor (13) runs through a dielectric comprising at least one dielectric layer (12, 15), an improved signal integrity in conjunction with simplified producability which is more flexible with regard to the layout is achieved by virtue of the fact that, for electrical radio-frequency screening, the at least one signal conductor (13) is surrounded by a plurality of electrically conductive holes (18), which are spaced apart from one another.
Claims28
Printed circuit board (10, 22, 26, 28, 32, 38), in which at least one signal conductor (13;
- 20, 21;
- 37, 39) runs through a dielectric comprising at least one dielectric layer (12, 15;
- 33, 35), characterized in that, for electrical radio-frequency screening, the at least one signal conductor (13;
- 20 21;
- 37, 39) is surrounded by a plurality of electrically conductive holes (18, 25, 29, 31) which are spaced apart from one another.
