These are not up to Dereks photographic
standards but here is a close up of a board
recently made.
http://www.thehacktory.com/88Wide.jpghttp://www.thehacktory.com/88Wide.jpgThe traces there are 8 thou.
Traces are going underneath 0402 components.
The photo was taken for another purpose than
showing of track widths so it is not of
the best part of the board for that.
When I get home tonight I will take photos
of the laser print-out on the transperancy
to show the edges of it. Will see if the
printer I use has the same fuzzy edge
problems as DJDelorie.
