Patent ID: 7053478

Claim:
A high-density circuit module comprising: a first CSP having upper and lower major surfaces and a first and a second edge, the edges delineating a lateral extent for the upper major surface, and having a first set of CSP contacts disposed on the lower major surface and arranged in an at least one array, the at least one array having at least one row with a row pitch and at least one column with a column pitch; a second CSP in a stacked disposition above the first CSP; flex circuitry connecting the first and second CSPs and disposed to place a first portion of the flex circuitry beneath the lower major surface of the first CSP and a second portion of the flex circuitry between the first and second CSPs; a form standard disposed between the first and second CSPs, the form standard having a lateral extent greater than the lateral extent of the upper major surface of the first CSP, the form standard presenting at least one surface for contact with the flex circuitry; module contacts attached to the flex circuitry and arranged in an at least one array, the at least one array having at least one row with a row pitch and at least one column with a column pitch, the column pitch of the at least one array of module contacts being less than the column pitch of the at least one array of CSP contacts.
