Currently I am
thinking about purchasing an Oki MFR-2241. The Oki
is not that expensive as a Metcal, but uses the same Smart Heat
technology that Oki got from Metcal.
I've not tried (or even seen) those.
OKI and Metcal on the same page. Even the naming scheme is similar.
(MFR-2210 => MX5010, MFR-2241 => MX5041)
The Metcal MX5000 stuff still runs at 13 MHz and is compatible to the
older MX500 system. The OKI MFR run at 450 kHz like the Metcal SP200
and PS-800, but offer the better cartridge system like the MX-series.
(The inferior tip system from the PS-800 is also available for the MFR
series if you need somthing cheap.) You can fit a MFR-PS1100 /
MFR-PS2200 power supply with the MFR-H6-SSC hand-piece to use Metcal
SP200 SSC cartridges. You can even by this in a package as MFR-1160.
Therefore a MFR-1160 should be about the same as a SP200. I see a SP200
on your bench. So, I think, an OKI MFR can't be that wrong.
Any special recommendations for cartridge geometries?
As a start I think I'll get a 1 mm and a 2.5 mm chisel cartridge for
through hole and biger stuff. For SMT touch up perhaps a 0.4 mm conical.
The "Smart Heat" stuff is half
of the battle, the tip plating is the other critical part.
I know. Thats why I
prefered ERSA up to now. They offer a good tip
If they don't skimp there, I'd say it'll
probably do well.
I hope. ;-)
If you end up getting one,
I'd appreciate knowing what you think of it.
I'll let you know.
