Abstract:
A method of reworking a multilayer printed circuit board having a predetermined array of solder pads electrically connected to respectively associated via lands on plated-through barrels on a first surface of the printed circuit board, each of the barrels extending through the printed circuit board to a second surface and interconnecting to predetermined wiring nets within the printed circuit board and each of the barrels further having an opening, said method comprising the steps of:a. identifying one of the solder pads requiring a changed electrical connection; b. removing the identified solder pad from the first surface without interrupting the wiring net associated therewith; c. selecting a repair wire; d. inserting a first end of the selected repair wire in the barrel opening associated with the identified and removed solder pad until a predetermined portion of the first end is exposed beyond the first surface; e. after insertion of the selected repair wire, shaping the end of the predetermined portion in a shaped end substantially in the shape and thickness of the identified and removed solder pad; f. positioning the shaped end on the first surface in a position to replace the removed identified solder pad; and g. affixing the positioned shaped end to the first surface.
