Patent ID: 7760513

Claim:
A circuit module comprising: (a) a rigid substrate having first and second opposing lateral sides, a long substrate axis and an edge, the rigid substrate exhibiting at least one primary adhesion feature depressed into the rigid substrate and oriented along an imaginary adhesion axis which is substantially perpendicularly to the long substrate axis; and (b) a flex circuit having first and second sides, the first side of the flex circuit having plural contacts adapted for connection of the circuit module to a circuit board socket and at least one of the first and second sides of the flex circuit being populated with plural memory ICs, the flex circuit being disposed about the edge of the rigid substrate covering the primary adhesion feature of the rigid substrate so that the primary adhesion feature is thus disposed between the flex circuit and the rigid substrate, the flex circuit being affixed to the rigid substrate with adhesive disposed in selected locations between the flex circuit and the rigid substrate.
