Michael, Your best bet, in my opinion is manual fan out routing. You may also want to consider using micro-via technology for such a dense BGA. Consult with your Fab house before going down this road, and you may have to consider the cost of such technology in your design as well. Cheers,

I have several BGA and one is a 652pin BGA. thanks in advance for any responces, tricks, or easier ways. michael b -----Original Message----- From: Ian Wilson [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 27, 2002 5:37 PM To: Protel EDA Forum Subject: Re: [PEDA] At 04:48 PM 27/02/02 -0600, you wrote: >Yup, you only can see the extent of the component when moving it, I think. >The method for getting a reasonable zoom and position of the center when >creating a component freehand (the "wizard" is pretty useless for the parts >I have to create from scratch) is klunky, at best.

I will usually start placing the first pad, tab to set the pad parameters, zoom in until I see the pad about the size I want and then J-L to jump to the required location for this pad (or just 0,0 to get close) and then click to place the pad. The extra time taken to zoom in is minor (no re-centring required) but, you are right, it is a bit clunky. Better would be the PCB library zoom starting with about 5 cm (2") extents.
