IntroductionAs chip designers pack more functions into ICs,pin counts continue to grow and the space betweenpins keeps shrinkING. Pin spacINGs of 0.5 mm and0.65 mm are not at all uncommon. The power ofthese new ICs is wonderful, to be sure, but trou-bleshootING them can be a chore because connect-ING scopes and logic analyzers has become muchmore difficult and less dependable.
