It's been a looong time since I've made my own boards, but I just pulled one to
check it for the qualities you seek. They look acceptable!
My technique used spray on photo resist, contact exposure to a large UV
source. Etching in heated Ferric Chloride with frequent agitation. I prepared
the boards by first scrubbing with Ajax followed by double rinsing. Resist was
sprayed on and baked in low temp oven (per instructions).
