Clark,

Actually, I'm not a "pcb guy" ;-)

When I want to make a board, I use pre-coated boards and contact printing.
Nothing special there.

My efforts, recently, have only been focused on making durable labels. I
have etched into brass plate to a depth of about 0.002" and it does look
good. This was done with David Pickering's technique. My problem was
painting the surface to give more contrast. That is what led me to toner
transfer onto powder coat. I get great contrast and a durable product. It
doesn't look nearly as nice as polished brass but is lower cost and higher
contrast.

As an aside, I have also been working on a method for easily radiusing the
corners of these plates. I've come up with a variation on a filing button
that is very low cost and easily make. The trick is to use magnets to clamp
the plate to the tool.

Rick

Dave's toner-transfer freezing technique

Hi Rick - thanks for replying...the process I'm interested in is toner
transfer onto shim brass for single-sided photoetching... I realize you pcb
guys only do a surface etch and undercutting is not an issue...is it?
that's why I ask if this toner transfer method will work for etching...
