Homebrew PCBs

Hi John

I've been using
the STAEDTLER permanent Lumocolor "S" 313-2
Its red ink, the pen has a black body with a  "S" on the red cap
The ink is a little clear on copper but works with ferric chloride
I buy them at the local newsagent about $3.25 have a scribble in the shop to check it out first

cheers

  Subject: [Homebrew_PCBs] PCB Touch up


  Hello All,
  I have a fairly complicated single-sided pcb that I am doing with
  toner transfer. The tracks and through-hole component pads are 12 mil.
  After several tries at T/T I have reached a 99.99% level of transfer.
  I wish to touch up the missing bits. However, the examples of a
  sharpie that I have seen here in OZ would be like trying to touch-up
  with a broomstick (and they call them fine point!!). So I am looking
  for advice and experience in touching up fine track resist; including
  make and model of known successful products.
  TIA
  Regards
  John C
