Yes, I'm trying it out too and it does indeed work. I'm aslo using his suggested mix of acid and peroxide as etchant.

Page has been updated since the last time I visited. Tried several types of paper (can't get the described type here) but no fun. My Laserjet 4Si does not seem to cover the sheets anyway neither for plain paper, nor for transparants nor for any other kind of sheets I tried. It's not just pinholes, you can see the light through it. Tried a new Laserjet of my brother (don't know the exact type) but achieve the same results. Ever tried with a Laserjet 5000 that seemed to do better, but have no access to it anymore.

Look for inkjet photo paper that has 1 side shinny, other side normal paper. The paper I tried is JET brand gloss finish, made by international paper company of memphis tn. Bar ID: 010199070333. As I said, It did a much better job than the normal toner transfer paper. No pits, and smooth dark traces. Even on some very fine traces. JTT...

JTT,

Thanks for mentioning my "pcb-making" webpage. I made that page, originally, because I didn't want everyone else to have to "re-invent the wheel", since it had taken me quite a bit of time and money to get the toner transfer method working well. It's especially-great for fast-turnaround prototyping needs, and/or for a very low budget.

I want to point out that there is a very good discussion group that's devoted to making your own PCBs. It's called Homebrew_PCBs, and is at

(P.S. Off-topic: I sure hope that everyone else has also downloaded Linear Tech Corp's free LT-SPICE circuit simulator (AKA SwitcherCAD III), from
