Damaged Conductor Repair Procedure for Single Layer Boards.
(1)
Solid Wire. All breaks in wire conductors must be repaired so that no reduction in cross section thickness will
result. Table 4-8 provides equivalent conductor widths and solid wire diameters. It is assumed that the broken
conductor is of the 2-ounce type which provides a margin of safety in selecting the equivalent wire diameter. Proceed
as follows:
(a)
Measure the conductor width and select the equivalent or next larger diameter solid wire.
