Although DIY PCB making has made great strides since the early days of chemical etching, there’s one fly in the ointment: vias. These connect individual layers of the board with a conductive tube, and ...
Today’s electronic packages have high clock speeds (multi-gigahertz range), fine pin densities (below 0.4-mm pitch), and high pin counts (over 2000). When assembled onto a printed-circuit board (PCB), ...
