SECOND AND LAST CALL TO RESPOND We are considering the benefits of such additive process technologies as SLC, Dycostrate etc. and the associated microvias attainable with laser, plasma etc. I need to gather information on cost trade-offs and have read within this forum that the traditional cost per area metric is not applicable size the same size area can easily contain substantially more devices & I/O's. Can anyone share some cost modeling or analysis they have done in this area? How about the board shops in this network that are pursuing the introduction of these technologies-how will you assist your customers with cost tradeoff info? Additionally I would like to understand the reworkability or lack thereof with such technologies. Thanks in advance for your technical advice.
