Hello,
I am looking for some info and help on a decent routing scheme for a 200+ pin PGA
socket. I am using only a 2 sided board right now, but wondering if a 4 layer layout
would be best. Customer wants to go low cost..
Seems you run out of routing room from the inside pins to the outside
The default via pad and hole size Protel uses is rather large,
a smaller via and hole size should probably be selected.
The other major factors would be the routing rules for:
- The spacing between the pins of the PGA socket.
- The trace widths.
- The clearance between the tracks and to the P
