If you end up getting one,
I'd appreciate knowing what you think of it.
The Oki MFR-2241 arrived today. I
did some (de-) soldering on scrap
PCBs in the last hours. It is amazing how the small 1 mm chisel
cartridge heats up large through hole pins soldered to big ground
planes. My old iron wolud not be able to do this, in no way. The OKi
tips are thin and short. Wheres the heater + tip of my old iron is much
thicker and longer. A touch up on a single SMD pin is much easier with
the OKi, as the total length of the tip is much shorter.
The "precision" tweezers aren't that precise as expected, but its OK.
Wane desolder that SO8? Grab with the tweezers, wait a second or two
and it comes off. Wane desolder that LM2676 (dPak)? Tin the leads for
better heat conduction, grab with the tweezers, wait some more seconds
(large ground plane under the chip) and it comes off...
My setup cost me 830 EUR (approx. 1055US$) including some tips.
The single PSU variant, MFR-1100, is 300 EUR (approx. 380US$). If you
are in buissines for a new soldering iron and can spend that much
money, get at least a MFR-1100.
It is worth every single cent!
I'll get a pair of larger tips for the tweezers later. These are
expensive, around 100 EUR. But desoldering a DIP16 or the like will be
a piece of cake with them.
p.s. At unpacking I noticed that the pacel had been droped top down
onto the flor. But the PSU survived without a single scratch. It is
build out of cast aluminium. It is heavy and build like a tank. Its
really industrial grade equipment.
