发明名称 Thermally enhanced ball grid array package
摘要 A thermally enhanced ball grid array package for electronic components, with an electronic and a plurality of ceramic component carriers bonded to a metal heat sink, enhances thermal performance, reduces solder ball fatigue and reduces stresses between the ceramic component carriers and the heat sink. Bonding the ceramic component carriers to the heat sink reduces expansion induced stresses of the solder balls on the carriers. Plural ceramic component carriers, smaller than a single carrier would have to be for the same package, reduce stresses at the interfaces between the ceramic component carriers and the heat sink.
