Looks good Xeno. When you mean development board, I take it that the board is used for chips that have already been programmed, is that correct? How are you programming them currently? I too have used the toner transfer method with variable success. As long as the trace width required doesn't go below about 12 thou, everything seems to work out ok. One thing I learned while rinsing off the paper is to not be too aggressive - using hot water and ammonia to soften the fibers seems to work without affecting the toner. A gentle rubbing releases the fibers that have been saturated, then leave to soak again. The longer the soaking time (30min +) between rubbings seems to work out better with intricate designs. I also noticed that if you leave behind paper fuzz it will not affect the etching process at all. I have been using peroxide and muriatic acid. BTW - the file link is not working.
