Hi ALan,
I tried pre-etching this morning and it may have helped.
After going through 12 sheets of Pulsar paper, I emailed them (Frank)
and he suggested I use a laminator rather than an iron. THe unit he
recommended for .062" thick boards is $129.00 right now - I will wait
till they go on sale.
Anyway, back to my pre-etch. On small test samples this proved to
help a lot. I was testing traces from .005" to .100", even the small
ones were staying put.
However, as soon as I tried on a bigger board, the toner wouldn't
stick again -grrr. The next time I am making boards - hopefully
tomorrow or Sunday, I will try a longer pre-etch to see if that helps
on the bigger boards.
Thanks again for all your help and suggestions!
