Desoldering

[Rowland-8]

Thanks for the comments guys regarding the 808  (China)
I have decided to give it a go and have ordered direct from China!!!
It will be interesting to see what the quality is likeand how well it
performs I have some PCB boards here to reclaim components from.
I will report back to the list when it arrives.
The type I have ordered does look similar to the Circuit Specialist
desoldering tool on their site. there appears to be a number of versions
on the market all coming from China.
Thanks again
Rowland

Rowland,

We had a discussion on the reflector some time ago about the Circuit
Specialist version of the Hakko, and the pros and cons of it.  It
SEEMED to be a direct copy of the Hakko, (right down to board layout
and parts placement and selection) but the main difference was the
quality of the tips.  The person that had one had reported the tips
are difficult to tin, don't like to stay "wet" from the Solder like
the Hakko tips, and so on.

Problem is, I DON'T remember if the TIPS are interchangable or
not.  If they are, that is where you would be wise to invest in the
Hakko tips.  If they don't, then it may be a dicer situation.

You might want to look back through the archives.  The thread to look for is:

I have the tip tinning problem with my Hakko 808. The 808 works great,
but the tip won't accept solder.  The manual says that is an
indication of a worn tip, but mine was brand new.  I though I just had
the wrong expectations.

I'll have to order a new tip before I try stripping and tinning toroid
leads again.  That was my only disappointment.

Matt,

The other thing unique to the Hakko tips is that they seemed to me to
be less tolerant of sponges for cleaning.  Hakko makes a little
cleaning thingy that I had much better luck with using than the
sponge that came with some of their units.  It uses metal that looks
like a Scrubber pad, but is an alloy that keeps the tips
happy.  There was a thread on this, and I think Tom Hammond has some
info on his web site about it:

You should NOT be experiencing much (if ANY) tip tinning problems with the
Hakko 808...

What steps have you attempted to clean/re-tin the tip so far?

I have a spiral-wrapped stainless steel ribbon kitchen scrubbie which I use
for cleaning my soldering iron (and Hakko 808) tips. It does a great job of
scraping off oxidation and leaves the tips ready to accept solder. See my
web  site at www.n0ss.net, just about to the bottom of the"Files Related To
Building" section (3rd line from bottom), you'll find a PDF related to the
Kitchen Scrubbie Soldering Iron Tip Cleaner.

Some of the Hakko 808's came with their thermostats (little blue [if I
recall] pot inset into the handle of the 808, but NOT the CAL pot) set
pretty 'hot'. This tended to allow the tips to oxidize all too quickly. It
also contributed to a tendency to over-heat a joint being desoldered,
resulting in occasional lifting of a trace or pad. I backed the temp down a
bit and both the trace and oxidation problems all but disappeared.

The Hakko 808 tips are IRON-plated, so they should clean up pretty easily,
even if you are a bit 'aggressive' with the cleaning... though NEVER file
or sandpaper the tips... that's the BEST WAY to remove all traces of the
iron plating... guaranteed... been there... did just that! But you should
be able to clean them up in order to get them to take solder.

73,

Tom   N0SS

Hi Tom,

I think I may have 'cooked' the tip the first time I used it.  I
couldn't decide which indicator on the pot was correct. I thought the
big indicator was an arrow head and the skinny one the arrow shaft.  I
was, of course, wrong.

Letting it heat up for 5 minutes before trying to use it at a high
setting probably oxidized the tip.  I'll get some of those scrubbies
and see if I can't clean it up.

Thanks for the tips!
