(Olin, don't give me the "you only get to pick two" thing :P) That fact that you asked me not to mention it means you've already learned something. Holes and vias was always a issue with the boards I did manually years ago. I found a drill press a must. Surely you know someone who has one. The trick about leaving little spots of etched copper at holes to act like guides helps, but such small spots can be problems themselves. You may have to manually make a dent with a centerpunch for each hole, then drill with a drill press. As for vias, you can consider most holes for thru hole leads as a via opportunity by soldering both on the top and the bottom of the board. Unfortunatly this doesn't work for DIP sockets since the top ends of the pins are not accessible. One time I used wire wrap sockets just to get the long leads. All the DIP sockets were then up off the board so that I could get at the top end of the pins. It looked silly but it worked. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
