    Hi all,
    Where can I buy a not too expensive pencel soldering iron with 0.1mm
    tip?
    I have checked local RadioShack and Fry's with no luck :(
    Thanks!
     
  2. I doubt you can get them.
    Anyway, even such a fine point, when dipped into tin
    becomes wider. The point in soldering such fine structures
    is to have two helpers, first the solder mask which
    repels tin from the surface and second flux gel or such
    that increases the surface tension of tin plus it bubbles
    when heated.

    You won't find one, it's impossible to coat a tip that small with iron etc.
    so that it'll last. 0.4 mm is the smallest made by Metcal. You could always
    file down a standard tip to get the width you need, but it won't last long.

  4. The coating will be destroyed though! And then you're left trying to
    push around globules of solder. :-(
     
  5. I have a cheap Antex 'C' iron (15W unregulated).
    A 0.12mm conical tip is available for it (cpc order code AN107).
    This tip is "available in unplated mallory only".
    I've not used mine very much and it's already eroding significantly.
    Might be worth investing in "Savbit alloy" solder to use with it
    (which contains disolved copper and is said to reduce erosion.)

    Mike.
