Patent ID: 7284992

Claim:
An electronic apparatus, comprising: a first level package structure comprising a package substrate having one or more IC (integrated circuit) chips mounted on a first surface of the package substrate and a first array of contacts of pitch P 1 formed on a second surface of the package substrate opposite the first surface; a second level package structure comprising a circuit board having a second array of contacts of pitch P 1 formed on a first surface thereof; an LGA (land grid array) connector disposed between the first and second level package structures to provide electrical interconnections between the first and second array of contacts, a flexible circuit having a third array of contacts with pitch P 1 , a fourth array of contacts with pitch P 2 , and wiring to connect the third and fourth array of contacts; and a support frame structure disposed around an outer perimeter of the package substrate and having first and second opposing surfaces, wherein a portion of the flexible circuit having the third array of contacts is attached to the second surface of the support frame structure such that the third array of contacts is disposed between the second surface of the support frame structure and the LGA connector and such that the LGA connector provides electrical connections between the third array of contacts and the second array of contacts, and wherein a portion of the flexible circuit having the fourth array of contacts extends toward the package substrate to provide electrical connections between the flexible circuit and the first level package structure.
