Homebrew PCBs

04-28-2006: Black, Magenta, Yellow are dry even when rubbed fairly
hard. Cyan, Magenta/Yellow, and Combo Black appear dry but feel
slightly soft and crock a little when rubbed hard. Coated back and
larger blank areas of front with Future Acrylic Floor Polish in
preparation for etching, back into the food dryer.

FeCl acid bath, failure. First tried the method using a sponge brush
to wipe etchant across the PCB, ink wiped off in the hot etchant. Used
a baster to flush etchant across the rest of the board, even then the
ink dissolved off. Spots where ink had puddled were first to go,
presumably they weren't completely dry. Lasting long enough to make
slight impressions: Black, Magenta, and Yellow. Cleaned and scrubbed
board. 

Tried the pre-etch suggested by some for toner transfer. Reprint
failure- ink bled outside the lines all over board. Cleaned and
scrubbed board, dried in toaster oven for an hour. Board slightly
orange due to oxidization. Got board hot just before feeding into
printer. Back to square one, but this time I'm drying it in the
toaster oven to try and get the ink truly dry.

I'll upload more pictures tomorrow.
