Kevin asked how to perform SMT mods using haywire/jumper-wire fixes. Jerry
Cupples provided a real good answer. I would only take exception to Jerry's
statement: "use the smallest wire you can". If a circuit handles digital
(logic) signals you may be OK that way. If the circuit handles analog or
unknown signals you need to assure that the cross-sectional area of the wire
(circular mils) being installed provides sufficient current carrying
capacity to do the job (Hint - compare with the cross sectional area of the
original trace). Note that the (recently published) Navy repair manual
(Recommended Requirements and Procedures for Repair of Electronic
Assemblies, by the Naval Air Warfare Center, Aircraft Division Lakehurst,
their Document NAWCADLKE-MISC-05-MT-0001) provides a table of solid wire
equivalents to various (2 oz.) conductor widths. Enjoy :) J. H. Moffitt,
