HI All, My design has a very high count (approx 20) 1mm pitch FPGAs with 1164 Ios.(part number XV2VP100) There is reasonable amount of interconnections between a few paired FPGAs. So I am exploring the option that whether I can place the FPGAs on the component side of my PCB to ease the routing effort. Need to check the feasibility/yield issues for this assembly process? Whether it is practical at all. What are the known issues which need to taken care for the same? This is a evaluation platform so a few prototypes only are required to be assembled. Thanking you all in advance, With best regards, Harjeet Singh. ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
