Re: Silicon coated foil

Myc--

Thanks! Guess I'm off to the grocery store tonight. ;)

Only thing I haven't liked about the Staples paper is getting the 
paper residue off. This foil could be interesting.

Any tips on how you stuck it to the carrier sheet, and do they remain 
together while you heat, and/or when you remove (soak??) the foil? 
I'll be using the clothes iron process with an aluminum plate 
attached.

                              -Thanks!

PS (Stefan)- I was about to post a question about the "etched through" 
sections you're fighting with. Be on the lookout for it. I'm thinking 
of grabbing a roll of Pulsar's TRF from DigiKey. One of my biggest 
problems with the over-etching seems to be from inconsistent chemical 
progress across the board, maybe due to larger masked areas dirtying 
up the etchant and killing it's strength in certain spots, causing me 
to over-etch the others. I had been manually agitating before, and 
have just built one of those small, flat, vertical tanks. It's got two 
bubblers in the bottom and a heater, so things should get a lot better 
soon.
