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

Subject: [TN] RD Technologies Vapor Phase Users
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,
