Abstract :
It is possible at present to assemble and test chip scale packaged (CSP) die in bump array pitches down to 0.4 mm. It is also possible to assemble and test bumped die in pitches below 150 μm. However, the volume users of these products assemble on laminate substrates made of FR4, FR5, BT or similar materials. The state of the art for lines, spaces, and through-holes limits the effectiveness of downsizing die packages. This paper examines the matches between these technologies and future matches between CSP pitches and mainboard technologies
