Abstract
Provided circuit modules employ flexible circuitry populated with integrated circuitry (ICs). The flex circuitry is disposed about a rigid substrate. Contacts distributed along the flexible circuitry provide connection between the module and an application environment. A strain relief portion of the flex circuitry has preferably fewer layers than the portion of the flex circuitry along which the integrated circuitry is disposed and may further may exhibit more flexibility than the portion of the flex circuit populated with integrated circuitry. The substrate form is preferably devised from thermally conductive materials.
Claims20
A circuit module comprising:
- (a) a rigid substrate having two opposing lateral sides and an edge;
- and
- (b) a rigid-flex circuit having a first and two second portions, the first portion of the rigid-flex circuit having plural contacts adapted for connection to a circuit board socket while the two second portions of the rigid-flex circuit being populated with plural memory CSPs, the first portion of the rigid-flex circuit being flexible and disposed about the edge of the rigid substrate while the two second portions of the rigid-flex circuit are rigid and are disposed on either of the two opposing lateral sides of the rigid substrate.
A circuit module comprising:
- (a) a rigid substrate having two opposing lateral sides and an edge;
- and
- (b) a flex circuit having at least one IC-mounting portion and a substrate transit portion, the at least one IC-mounting portion having first and second sides and the substrate transit portion being disposed about the edge of the rigid substrate, the IC-mounting portion of the flex circuit having more layers than the substrate transit portion exhibits.
