  • Patent number: 6239981
    Abstract: A packaging substrate is provided such that an electronic components having a plurality of connecting terminals at their side edge portions and other kind of electronic component are mounted in high density on the substrate. More specifically, in a packaging substrate having IC packages (electronic components) surface mounted on the substrate, the package body of each IC package having a plurality of outwardly extending lead terminals at their side edge portions, the package body of the IC package includes at its side edge portion a specified length open region with no connecting terminal disposed therein. The IC packages are arranged in such a way that open regions of adjacent IC packages are positioned so as to confront each other and that front ends of individual leads are kept in closely spaced relation within a specified spacing range, a bypass capacitor (other kind of electronic component) being surface mounted between the open regions of the adjacent IC packages.
