    I'm looking at a used Pace temp-control soldering station model ST45. I did a
    usenet search this model and came up empty. This seems quite odd.

    If you have experience with this model, I'd like to hear about it.

    What do you like about it? Don't like about it?

    Thanks,

    Dave,
    So as not to keep you hanging, I work for a small business in the Northwest
    that has several Pace units on inventory. I will see what is there and get
    back to you ASAP.

    Yes, this is Pace's equivalent to Weller (WESD51) and Haako (937?) of
    similar configuration (Digital temperature readout).
    Good station. Case was thermoplastic. Model has been superseded by ST-50
    (IntelliHeat Control Technology).
    ST-45 system is supplied with PS-90 (SensaTemp model).

    Thus spake g. beat:
    Yes, I saw the web site.

    Google is not always The Answer.

    I searched *usenet* to find discussions of this model in *news groups*. I'm
    trying to get a bead on whether this is a good unit (I'm sure the Pace pages
    will say "yes!") or something to avoid.

    Looking for *experiences* with this model, or Pace stations in general.

    They are expensive, but they do have a lot of special soldering tips
    for repair. OTOH, you'll only need special tools when you are working
    on a board with components on both sides and need to remove a
    component without destroying it. When working at one of my previous
    employers I had access to a Pace soldering station but I found my own
    tricks worked much faster than setting up the Pace.

    If you are looking for just a soldering iron, I can recommend Ersa.
    Their soldering tips last much longer than the ones from Weller. Ersa
    also carries special tips for soldering fine pitch.

    Nico,
    I know very little about this topic, other than soldering regular pcbs
    (non-SMD).

    If you wouldn't mind, would you explain what you mean about why you need
    special tips or tools if pcb has components on both sides? And what are your
    own tricks?

    Thanks,

    Pace sells special tips for removing ICs in surface mounted packages.
    They also have a tweezer like soldering iron (in fact 2 irons in one)
    with which you can solder both joints of SMT resistors and capacitors
    at once.

    For soldering fine pitch I use a hollow tip (which is available from
    any major soldering iron manufacturor). It takes some practice, but it
    is manageble.

    I remove fine pitch chips from epoxy (FR4) PCBs by heating the PCB
    -carefully- with a paint stripper. This is non-destructive for the
    component.

    Desoldering fine pitch chips on a board with componentes on both sides
    is more tricky (and destructive for the component) since the paint
    stripper method won't work. I run a enamel copper wire underneath the
    pins. Next I attach the wire to a component or via somewhere on the
    board. Finally I heat the pads one by one and gently pull the pins
    from the pads by pulling the copper wire. This method puts very little
    strain on the pads of the PCB so it can also be used on paper based
    PCBs. However, all the pins on the package get bend.

    Let's see, I own 3 (MBT250, ST20 station, PS90 and PS80 irons and I repair
    them ..
    yes on the used market - if you know what they are - they are a great buy.

    Thus spake g. beat:
    Thanks, g.b.. Your comments are hereby added to my d.b. of Pace experiences.
    I'm leaning toward buying this ST45 station. I'll have to buy tips on-line (I
    prefer to be able to dash down to the local electronics supplier when I need
    it *now*), but I guess I'll have to plan ahead a bit...

    Thanks again,

    Dave -

    Remember that expect for the ST-25 and ST-45, Pace really doe snot target
    the hobbyists market - which is really where Weller, the Far East imports
    and some Haako models exist.

    Oki(Metcal) and Pace are usually seen in the professional work place
    (production rework, SMT)
    with some Weller and Haako.

    The only caution that I would add is this:
    The thermoplastic extrusions for the ST-25 / ST-45 or ST-65
    are no longer available from Pace.
    At that time Pace made the ST-35/ST-55/ST-85 which were the aluminum
    extrusion case versions (with ability to mount the power supply base under a
    bench-top or bench shelf.

    So my only warning is avoid heating / burning the case with hot iron - it
    will stay that way.
    When I do not deal directly with Pace factory -
    I work with Technimark and Chicago area Pace representatives - for parts,
    etc.

    In my limited experience 5 mil nickel wire works better, and there are tools
    to put the leads back into shape. The just get real expensive for fine
    pitch.
