Abstract
An efficient cooling mechanism for a multi-chip carrier can be provided while conserving board surface area. Flexible circuitized material is used to form multi-chip carriers with air baffle capability. The flex is folded or curved into the desired shape and held in position with a support structure. Bonding sites for chips are located on regions through the carrier. Shapes which provide air baffle capabilities include coils, spring-like coils and serpentines.
