Breakout Boards

  • Single-sided SOIC-24 (narrow) to DIP with .6″ spacing using 12-mil traces and 9-mil isolation. I was able to produce it just fine with toner transfer using a household iron and plain old ferric chloride, but board houses may not be too thrilled with it. Also note that the spacing around the SOIC was very tight in order to maintain the .6″ header spacing.
