Apparatuses, systems and methods associated with dielectric coatings for printed circuit boards are disclosed herein. In embodiments, a printed circuit board (PCB) includes a substrate, microstrip conductors located on a surface of the substrate, a solder mask covering the surface of the substrate and the microstrip conductors, and a dielectric coating located on the solder mask, the dielectric coating on an opposite side of the solder mask from the microstrip conductors, wherein a thickness of the dielectric coating is selected to cause a ratio of capacitive coupling to self capacitance to be approximately equal to a ratio of inductive coupling to self inductance for each microstrip conductor of the microstrip conductors, where the thickness may be determined based on a specific methodology including simulations. Other embodiments may be described and/or claimed.

Dielectric coating for crosstalk reduction

A printed circuit board, according one embodiment, includes a reference layer; a dielectric layer disposed on the reference layer; and a conductor layer adhered to the dielectric layer with an adhesive layer disposed between the dielectric layer and the conductor layer. The conductor layer has a smooth surface facing the dielectric layer having a roughness (Rz) of less than two microns.

Reduction of insertion loss in printed circuit board signal traces

A signal line design is described herein. A circuit board may include a first signal line and a second signal line. The first signal line includes a pair of signal lines at a first depth of a section of a circuit board, wherein a centerline extends lengthwise between the pair of signal lines. The second signal line is disposed at a second depth of the circuit board. The second signal line includes a first segment that runs parallel to the first signal line at a first displacement from the center line. The second signal line includes a second segment that runs parallel to the first signal line on the other side of the center line at a second displacement distance from the center line.
