Ideally - do this in separate areas, although inevitibly a bottle of rework flux would mysteriously walk from one area to the other. Education will be key to success in this. Some scheme of idendifying which flux is which AND which boards are which is also essential.
There's nothing quite like a board reworked with OA flux that catches fire in a powered thermal shock oven to stink a place up.
good luck!

We use mostly OA flux for all applications, but some hardware requires RMA.
We have color-coated flux dispensers and bobbins for wire solder, and our
solder wick has no flux at all. This seems to work well.

Subject: [TN] Chemistries on production floor
Hello,
Our company will soon be introducing No-clean chemistries into our
production on certain customers. I like to know what practices are
being
applied to ensure correct handling and distinguish of OA/ No-clean
chemistries on the production floor. Any advice on process control
is
appreciated.
Does anyone have any issue with having more than one chemistries on
the
floor? E.g. identification of in-process units built with different
chemistries.
Rgds,
Peter
