Abstract

As Motorola products become smaller, many design- ers are incorporating CS chip carriers into their prod- ucts in order to save valuable pc board space. The accuracy ofthe CS placement and mechanical reliability of C5 components are critical because post placement inspection requires either the use of expensive X-ray technology or the use of destructive inspection meth- ods, both of which increase the cost of manufacturing.
