HELLOOO TECHNET,
        This is just a follow up question to a topic that was discussed a 
     few months ago.  The topic was the IPC-D-275 current capacity chart 
     (figure 3-4 page 10).  Ralph Hersey had stated he was in the process 
     of creating a formula/spreadsheet for this data.  Well, I have a large 
     backplane coming up and that spreadsheet would be real handy...
     
                                                regards,
                                                        Rob
