High density electronics packaging assessment for military environment

Raytheon Electronic Systems has been aggressively pursuing high-density electronics packaging technologies such as Ball Grid Array (BGA) and Chip Scale Packaging (CSP) for its military and space applications. Because of the rapid pace of integrated circuit technology where the silicon technology industry is already moving toward systems-on-chip (SOC), it becomes crucial and apparent that the electronics packaging industry must continue to meet the needs of the silicon density proliferation. Design and manufacturing engineers must stay abreast of the rapidly changing high-density packaging technology and its applications. Raytheon plays an important and active role with the EGA and CSP "in-kind" consortia started in 1995 and 1997, respectively. The consortia consist of many companies with diverse disciplines from commercial to space and aerospace industries. This paper will highlight Raytheon's role with the consortia for the current Microvia PWB test vehicle design which encompasses new generation CSPs, Microvia board fabrication and to some extent PWB assembly.
