Abstract
A rework configuration is provided for disconnecting defective lithography-formed conductors and/or overlying electrical components from the printed circuit wiring netlist and connecting rework elements at the substituted sites. In particular, defective regions can be severed at spaced first and second target areas upon the upper surface of the PCB and one or more interconnect structures can be coupled therebetween. The interconnect structures allow re-routing of PCB conductors, allow connectivity between the upper and lower surfaces, allow connectivity to power and ground planes, and allow pull-up, pull-down and decoupling connectivity.
