It says something for the status of FR4 as an everyday material that people notice when a printed circuit board (PCB) is not green. Yet both the fibreglass – yet another product of silicon – and the ...
All 50Ω microstrip lines in FR4 have the same aspect ratio. Using a 2D field solver, we can explore what this ratio is for a specific value of Dk (dielectric constant) and conductor thickness. Spoiler ...
The introduction of several new dielectric materials for high-speed ultra-large-scale integration (ULSI) microelectronics has increased the necessity for metrology tools to measure the ...
