Working Paper

This working paper describes a collection of LISP programs written to examine the backs of printed circuit boards. These programs find and trace the conductive wires plated on the insulating material. The "pads", or solder connections between these plated wires and leads from components on the front of the board, are also recognized and located by these programs.
