Yes
you can, our machine came with a proflow and sqeegee head. You just have
to power cycle the machine to go from one to the other. (Plus change heads
- a couple of bolts and a few connectors.)
Hi Henry!
I don't have any
answers to your dilema, but your post does bring up some
questions...
Once you have ProFlow installed on the printer, can you go
to regular squeegees if you need to? I know I could call DEK and find that
out, but I like to hear from us guys...
I have a DEK-288, and I can get
it retro-fitted with ProFlow, but I wonder if things go haywire, can I go back
to analog=squeegees.
This is something that I've thought about with my
new wave solder...I've got an Electrovert Electra...everything is computer
controlled...so if my computer crashes on the machine (It's Windows NT, makes
me feel a little better...) I'm basically DIW...sorry, Navy term (Dead In the
Water).

We are having some issues with a new solder paste. The
evaluations came out
extremely well at first. However, upon using
it for some trial runs, we run
into some problems.
In our DEK
profolw the prints look very good at about 20 deg C. Throughout
the
day, the temp in our facility climbs to 28 or even 30 deg C. The
prints
then start to bridge and flux bleeds out onto the board. We
can compensate
for it to about 25 deg by reducing the proflow pressure
and wiping on every
print, but beyond 25 deg, nothing helps.
By
the time the 3rd shift rolls in, the temperature starts to drop again
and
the prints become more managable again.
Here's the kicker, we
use this same paste on our MPM with squeegee's and the
print works every
time. There is never a print problem vs temperature.
Has
anybody ever run into this situation? How did you solve
it?
Thanks in advance.
