Abstract

A ball grid array (BGA) electronic component package having a configuration which is capable of improving mounting efficiency as well as preventing footprints from breaking away at circuit-connecting portions of the electronic component package. The BGA package has reinforcing bumps formed in an area located outward of a predetermined area in which conventional circuit-connecting bumps are arranged. Therefore, even if a shock is applied to the BGA package e.g. when a printed circuit board having the BGA package mounted thereon is carelessly dropped during the manufacturing work, at the outer or peripheral portion of the BGA package, which is most sensitive to such a shock, the shock is absorbed by the reinforcing bumps and reinforcing footprints which have no electrical connection with the circuitry of the electronic component package. Thus, the footprints formed on a mounting portion of the BGA package and those formed on the printed circuit board can be prevented from breaking away or being cracked.
