Patent ID: 7495334

Claim:
A high-density circuit module comprising: a first CSP having a body with first and second lateral sides and upper and lower major surfaces with contacts along the lower major surface; a second CSP having a body with first and second lateral sides and upper and lower major surfaces with contacts along the lower major surface; a form standard disposed along the-upper major surface of the body of the first CSP and having first and second curvature areas arcing around the first and second lateral sides of the body of the first CSP, respectively; a first flex circuit having first and second conductive layers between which conductive layers is an intermediate layer; a second flex circuit having first and second conductive layers between which conductive layers is an intermediate layer; the first and second flex circuits being disposed, in part, beneath the body of the second CSP and above the form standard as it is disposed along the upper surface of the body of the first CSP and about the first and second curvature areas of the form standard, respectively, and beneath the lower major surface of the body of the first CSP to connect with the contacts along the lower major surface of the first CSP; and a set of module contacts connected to the first and second flex circuits.
