Dan. I have been working on these boards of yours behind the scenes. I am doing the laser drilling of all your holes. Our experience is that if you keep your aspect ratio to < or equal to 1:1 (which you are) then any shop with a good board permanganate line and a good electro-less line should be able to plate these holes to your satisfaction. We have reccomended alternative shops. I think once boards are made with these newer shops you will see an improvement in yield. Regards, Jim Morrison Lumonics, Inc [log in to unmask]
