I'm interested in IR Reflow soldering thru-hole and SMT components at 
the same time, and I'm wondering if there are many others doing this.

     I have these questions for starters

Is stenciling OK?
Is dot dispensing OK?
Which is better?
How about solder preforms?
What about stencil thickness and aperture opening versus hole size 
and lead diameter?
Any special placement techniques?
Will flux fall onto the heaters and cause cleanup/fire problems
     (using RMA paste cleaning with in line aqueous cleaner and Armakleen )
What are the defects rates versus hand or wave solder? ( using 
IPC-610 class II )
Has there been any articles on this subject.

Thanks in advance for any help
