When does it make C to give up physical test access?

Abstract

As conventional board designs continue to decrease in size, the cost of "test" is rising proportionally relative to physical, bed-of-nails access. The purpose of this paper is to provide a generalized framework by which users can more quantitatively analyze the costs and benefits of removing physical test access from conventional, surface mount technology (SMT) boards for the purpose of bed-of-nails testing.
