Soldering Stations??

[Deni F5VJC]

I'm hoping to get a Hakko 936 (or it's clone) very soon and wondering
what would be the best tip to order for SMT work? I'll be building the
SoftRock Lite kit for use with my K3 so have decided it's time to
upgrade the soldering tools. I've  managed a small SMT project for my K2
using my old and trusty Weller but now want something better. I know
quite a few in this group use the Hakko so I would appreciate some
advice on iron tip sizes for SMT as well as the normal sizes.

Deni,
        If you should end up with a Hakko 936, be sure to check out the
Power/On LED modification at
http://www.n0ss.net/hakko_936_on-off_led_mod_v3.pdf.  It is a simple mod
that is well worth your time.

For what (little) it may be wroth, here is a bit of 'boilerplate'
reply which I send to folks who write me asking about tips for their
Hakko 936-x... Hope this helps.

   If you have the HAKKO 936-12 (ESD) or the -09 (non-ESD), the
   tips you're probably looking for are the 900M & 900L series.
   The "L" series is generally a longer tip.

   900M-T-LB     Long, round, .008" tip, really skinny,
                 helpful when cleaning out PCB holes

   All of the following tips are of the chisel (screwdriver) tip
   type:

   900M-T-I    .008" (0.2mm) tip  -   For SMD PC boards

   900M-T-1.2D .047" (1.2mm) tip --
                                  |   For PCB work. The HAKKO 936-12
   900M-T-1.6D .063" (1.6mm) tip  |-- and -9 models ship with the
                                  |   900M-T-1.6D tip included
   900M-T-2.4D .095" (2.4mm) tip --

   900M-T-3.2D .126" (3.2mm) tip - For non-PCB work

   900M-T-S3   .205" (5.2mm) tip - For heavy-duty work,
                                   including Coax Conns.

   900L-T-S1   .221" (5.6mm) tip - For heavy-duty work,
                                   especially coax conns.

   Try to select a tip which isn't longer than needed... the
   longer the tip, the more heat is lost getting it to the tip.
   Shorter tips generally are higher-mass and convey more heat TO
   the tip.. as long as they're long enough to reach into spots
   where you need to solder.

I have found the 900M-T-I (above) to work quite nicely for the
relatively small amount of SMD work I have undertaken. Nice fine
point, and easy to get in/out of the work... so far anyway.

73,
