Homebrew PCBs

Hi all, I know this answer comes a little bit late, but I haven't seen
anyone mention it and I have been getting very good results with it. I am
using Time magazine paper with a laminator. It works PERFECT, I can do
traces from 3.3 mils wide with 5 mils clearance for small boards, I havent
tried using such tigh specs for big boards(for which I usually use 8mils
traces and 8 mils clearance). I have tried many papers and this one is the
best by far and pretty easy to get. Just one thing is not to feed it
directly to the printer since it will most probably get stuck, instead i
hold it on a normal paper with some tape and insert the whole stuff to the
printer.

  Asunto: [Homebrew_PCBs] Toner Transfer questions...


  Being new to this, I am trying to make a toner transfer board. I have
  made one very simple postage stamp sized board and it worked OK. I am
  now trying to do a slightly more complex board (in a crawl-walk-run
  kinda thing) and am having a lot less luck. I have tried to transfer
  a couple of times and decided it wouldn't work right.

  I am printing on my regular 20lb 84 brightness Georgia
  Pacific "Copier Paper" $3 from walmart, and it leaves a lot
  of "hairs" on the toner. If I am aggressive enough to get these off,
  I also pull the toner off the board.

  How hard should I try to get these off? My first thought was they too
  will act as resist and I need to get them all off, is this true?
  Becaused my second thought was that they'll absorb the etchant (FeCl)
  and etch anyway albeit a bit slower.

  Is there any better paper out there that won't cost a fortune, I have
  seen the press'n'peel stuff and at $2 a sheet it's a bit costly if
  it's one shot. I have a small budget but I can afford to use a bit of
  time on the process.

  As an off topic question (and please if you reply to this reply
  personally) does anyone have any experience using the Zilog Z80 as a
  micro controller?
