It seems the only way to deal with them is to create each footprint from scratch eachtime I have to use one. Nearly eachtime I try to use an existing footprint things turn out wrong. There seems to be nearly no standardization in these things. Each chip manufacturer gives them a different name, pcb uses yet another one (if a footprint exits). Different manufacturers call different sizes by the same name. You never know how wide something calles SOP really is etc. So for my latest board I needed something called TSOP-28 in the datasheet. I found something by the same name in pcb. I carefully checked dimensions. They matched. I created a geda symbol. Today I got the chips and started soldering. Then I noticed something seemed wrong. The manufacturer had used a different pin numbering.
Why can't manufacturers just provide footprint and symbol in some standard format that all programs could import? I feel like I spend a large part of the time it takes to design a pcb drawing symbols, footprints, etc. Philipp _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
