Honestly,
I've never had to clean the preheat section. However, the vapor chamber is
where I've spent most of my time. You'll get flux residue on the walls, and
a nice green "algae-ish" stuff on the cooling coils. And you're right, it is
NOT fun to clean. I wouldn't try the Easy-Off either, it just makes more of
a mess than anything. I definitely clean more often then 200 hours.
I would imagine the 230 fluid you have is for 63/37 soldering.
BTW, I tried looking fluid that went higher than 260 (for HMP paste). I
couldn't find any.

Hi Jason!
We have some of the same fluid as you, although we have some LS-230 too (not
quite sure why that fluid is there...need to ask some questions about that.
I read the manual and it said the vapor chamber should be cleaned every 200
hours of operation, is that what you've found too? Or should it be cleaned
more (or less) often? Also, is the vapor chamber what gets most dirty? Or
does the area around the preheat panels get dirty too?
Looking at the machine, I can see that it is going to be a pain to clean
everything down inside the vapor chamber as they state in the manual.
Kind regards,

Hi Ramon,
Pros:
-Ability to process problematic high temp boards (thicker than .063", high
layer counts, etc.) and not have to jack with as many variables as in
convection or IR -Excellent thermal equilibrium across the assembly and not
having to worry about shadowing or thermal thieving -Probing your board to
determine preheat and then knowing your peak area's temp already and looking
through a little window to observe reflow and giving an extra 15 or 20
seconds over for wetting
Cons:
-Fluid is expensive and if you have excess dragout, you will notice
financially. Fluid is about $1000/gallon -Higher than usual expectations for
tombstoning if your board design is a little lopsided (heavy ground planes
connected to one side of passives) or if your process is a little off.
-Machine is a booger to clean

Hi Jason:
I believe that Vapor phase has a lot of good merits.
Could you share your experience with the machine? Pros and Cons.
Regards,
Ramon

Hello Steve,
We have a RD here and we use Galden HS-260

Mornin' All!
I've just got the opportunity to work with a new vapor phase reflow system
here at my new position. It's a RD Technologies RD3 with a vapor recovery
system. We're in the process of hooking it up, we haven't yet started it up.
I worked with a vapor phase many years ago (1988), and this system is much
nicer than what I remember about the system I worked with in the past.
I was wondering if there are any RD Technologies users out there that have
any "words of wisdom" that they might share with me about the system I'm
that going to be working with. BTW, we're going to using Galden heat
transfer fluids.
Kind regards,
