Flex-based circuit module
View Patent ↗A form standard provides a physical form that allows many of the varying package sizes found in the broad family of CSP packages to be used to advantage while employing a standard connective flex circuitry design that is disposed about the form. In a preferred embodiment, the form standard will be devised of heat transference material such as copper to improve thermal performance.
1. A circuit module comprising:
a flex circuit populated with CSPs and which flex circuit exhibits plural connective contacts, and including first and second conductive layers; and
an axial form about which the flex circuit is disposed to present the plural connective contacts for connection to an application environment;
wherein CSP contacts contact a first surface of the first conductive layer and application environment contacts contact a second surface of the first conductive layer.
2. The circuit module of claim 1 in which the axial form is a form standard that is comprised of metallic material.
3. The circuit module of claim 2 in which the CSPs include CSPs of a first type and at least one CSP of a second type.
4. The circuit module of claim 2 in which the CSPs are memory devices.
