Test Post - Nial Stewart - 2010-02-12 09:18:00
I posted a query about 10 layer PCBs for a new board I'm doing. I caught a reply by Rickman at home via Google, but it seems to have disappeared now. My usenet connection's normally pretty reliable so I'm not sure what's going on. Will this get out? Nial.______________________________

Google groups sees your post. Also your thread is still showing up there. It doesn't show your thread as new, but rather as a change in subject: Board layout for FPGA Discussion subject changed to "10 layer stack for 1152 pin BGA routing (and decoupling)?" by Nial Stewart Perhaps your newsreader still shows the original subject line? Regards, Gabor

Must be working too hard! Nial.______________________________

I've given up on that last thread, but I'm a glutton for religious wars, because when I win/martyr myself, my religion promises me a stripper factory and a beer volcano. It's gospel! Anyway, perhaps when/if you do, you could make clear whether you are using a 1152 pin package because you want to use all the I/O or the reason is you need so much logic for your application that you need that big a package. Are you gonna use any gigabit stuff to the BGA? If so, what rate? What are you connecting the 1152 pin part to? Is the 1152 pin part an FPGA? How many supplies does the 1152 pin part need? A power budget would be useful for each supply. What rise time are you shooting for on the I/O from this BGA? Nial, have you ever been in a Turkish prison? Is this board going to be sold? In a metal box? Does it need CE approval or somesuch? What are the PCB's dimensions, HxWxD? How much time/money have you got? What stackups have you used before? Do you do layout yourself? Anyone who has to regularly cope with a big package, as is my burden, knows that these are important parameters. Cheers then, Syms. p.s. I nearly posted this with a typoed hereafter boast of a 'bee volcano'. Which would not be nearly as good! RAmen.
