Abstract:
1. An electronic device comprising: a wiring substrate including an upper surface, a plurality of first electrode pads formed over the upper surface, and under surface opposed to the upper surface, a plurality of second electrode pads formed over the under surface, and a plurality of third electrode pads formed over the under surface; at least one first electronic component placed over the upper surface of the wiring substrate and electrically coupled with corresponding ones of the first electrode pads via corresponding first conductive members; at least one second electronic component placed over the under surface of the wiring substrate and electrically coupled with corresponding ones of the second electrode pads via corresponding second conductive members; a plurality of leads placed over the under surface of the wiring substrate and electrically coupled with the third electrode pads via corresponding third conductive members; and a sealing body formed over the under surface of the wiring substrate and sealing the second electronic component and the leads, wherein each lead includes a first portion extended along the under surface of the wiring substrate, a second portion formed integrally with the first portion and bent from the first portion in a direction away from the under surface of the wiring substrate, and a third portion formed integrally with the second portion and bent from the second portion, wherein the third portion is positioned closer to the peripheral edge portion side of the under surface of the wiring substrate than the first portion, and arranged at a position farther from the under surface of the wiring substrate than the first portion, wherein each lead is covered with the sealing body such that the third portion is exposed from the front surface and side surface of the sealing body, wherein the sealing body is not formed over the upper surface of the wiring substrate and the first electronic component is exposed, wherein the second electronic component includes a semiconductor chip, wherein the third portion of each lead exposed from the sealing body functions as a terminal external coupling, wherein the third portion of each the lead exposed from the sealing body functions as a terminal for external coupling for solder mounting, wherein the surfaces of the third portion of each lead exposed from the front surface and the side surface of the sealing body are contiguous, wherein over the upper surface of the wiring substrate, there is placed no wire-bonded electronic component, wherein the third portion of each lead is bent from the second portion and extended in a direction parallel with the first portion, wherein predetermined first, second, and third electrode pads are electrically coupled together via a conductor layer in the wiring substrate, wherein in the under surface of the wiring substrate, the third electrode pads are positioned closer to the peripheral edge portion side of the under surface than the second electrode pads, wherein the sealing body is a resin sealing body, wherein each of the first conductive members is solder, wherein the first portion of each lead is coupled to a corresponding third electrode pad via the corresponding third conductive member, and wherein each of the third conductive members is solder.
