Hello,

        We are having problems with our paste tack time not lasting as long
this time of year.  We are running at 14% humidity now, normal is about 40%
to 50%.  We are using a water soluble paste, 90% metal content, with a
quoted tack time of 6 hours on stencil, and 6 hours on board.  We are seeing
problems after 3 to 4 hours.  Does anyone have experience to say this is
normal for the humidity, or ideas as to what we could be doing wrong.(I know
of plenty myself, but still would appreciate more).

Thanks 

Steve Quinn
