Donnn,
Donnn,

To add my experience of working with OSP (Entek Plus 106A),
you never get 100% hole-fill with wavesoldering process.   You
get a better result with Organic flux (Water-soluble flux) since
they are more active.  I suggest you contact Enthone, Kester,
Alpha-metal and/or other flux mfg.  Most flux mfg's have
no-clean flux formulated especially for OSP coated boards.

OSP formulated no-clean flux is more active and give a better
result filling holes.  Since you are working with IPC Class 3, it is
more hassle with unfilled hole,  I am happy with 75% hole fill.
