## Abstract The recovery of copper, lead and tin from scrap printed circuit boards (PCBs) has been achieved using a combination of leaching, electrochemical ion exchange and electrodeposition. A simple aqueous nitric acid stripping solution, with the concentration range of 1β6βmolβ dm^β3^, has demon

Several methods used for the prerouting analysis of printed circuit boards are compared. The quality of a method is expressed as the correlation between predicted at~f actual values of objective measures of (in interconnection problem complexity. The experimental data confirm that some indicators of
## Abstract With the increase of operating frequency and circuitβcomponent density, signal/power integrity issues due to ground bounces become more important for highβspeed digital systems. This paper presents a modal analysis resulting in a multiport equivalent circuit model for the power/ground p
