FLUX EVACUATION SYSTEM (FLUX FLOW CONTROL
TM
)
The Flux Evacuation System is:
Standard, (installed on all ovens)
An option, (NOT installed on all ovens)
NOTE: The Flux Evacuation System is STANDARD on all N
2
Ovens
PURPOSE
The Vitronics Soltec Flux Evacuation System is designed to reduce the flow of flux fumes into the cool zones of the
tunnel, resulting in longer maintenance intervals.
APPLICATION
The Flux Evacuation System is the standard gas management system on Vitronics Soltec ovens equipped with the
Nitrogen option. This configuration is best suited for applications running nearly exclusively nitrogen recipes. The
oven is setup to minimize tunnel maintenance, optimize nitrogen performance, minimize O2 levels, and minimize N2
consumption.
BENEFITS
The XPM3m
series Flux Evacuation System is designed to inhibit the flow of hot flux fumes into the cool zones of
the tunnel (where they can cause maintenance problems), while still optimizing nitrogen performance. This control
of gas flow insures a cleaner cooling zone with maintenance intervals significantly increased. Although widely
varying process parameters will cause individual maintenance intervals to differ, an average expectation should be
up to 8 times less frequent.
The Flux Evacuation System has secondary benefits. In all applications, there should be a noticeable reduction in
cooling zone temperatures. Actual reductions will, of course, be dependent on individual process parameters. The
Flux Evacuation System will not adversely effect nitrogen consumption or 02-PPM levels, as specified by Vitronics
Soltec for XPM3m series ovens.
It is important to be aware that fan speed settings lower than 2500 RPM will disable the
Flux Evacuation System and will increase flux contamination in the oven
MAINTENANCE
The Flux Evacuation System is virtually maintenance free if operating properly. To ensure this, it is recommended
that the inlet tube from the Flux Flow Control manifold into zone 2 be checked periodically (every three months) for
flux residue. If a flux accumulation is noticed, the flux evacuation manifold may need to be cleaned.
