Abstract
A two-card assembly includes a first printed wiring board (PWB) on a first side of the two-card assembly, and a first stiffener secured to the first PWB. The two-card assembly also includes a second PWB on a second side of the two-card assembly, and a second stiffener secured to the second PWB. A center stiffener is disposed between the first stiffener and the second stiffener, and one or more electronic modules are secured to the center stiffener. The center stiffener dissipates heat from the one or more electronic modules.

A two-card assembly comprising:
- a first printed wiring board (PWB) on a first side of the two-card assembly;
- a first stiffener secured to the first PWB;
- a second PWB on a second side of the two-card assembly;
- a second stiffener secured to the second PWB;
- a center stiffener disposed between the first stiffener and the second stiffener, wherein the center stiffener is disposed in a slot that is formed within the second stiffener;
- and
- one or more electronic modules secured to the center stiffener, wherein the center stiffener dissipates heat from the one or more electronic modules.
