Hello Rick, My experience(little that there is) is that this is achieveable, providing that your paste has a large process window. Paste technology has evolved to more of a "bell curve" type of profile plot. In the past, soak time and temp was much more critical. Now, you can get away with more. Hope I've helped. jg --- Rick Thompson <[log in to unmask]> wrote: > I've inherited a system of maintaining oven profiles > where each assembly was > given it's own profile.
