Hi Todd,
We did this quite a bit at a former employer of mine (high performance
commercial, medical, and defense-COTS hardware) with generally good
results.  And although you get "good" through hole fillets, they don't meet
the IPC spec, so our workmanship requirements always had a waiver in this
department.  We only had 1 customer in 4+ years that I can remember who
questioned this and who asked for significant touch-up.

Regards,

Anyone out there doing intrusive reflow with OSP mixed tech. (SM + TH)
double
sided boards?  We are considering it (for cost and cycle time purposes).
Do you
get good solder filets for the TH parts (knowing that you have decreased
wetting
action in OSP holes vs. HASL)?  Any other issues to be aware of?


Todd
