Sure there are, just contact your supplier, it would be amazing if your
supplier does not have a halide free functional equivalent, or something
close. The reason is simple enough and is nothing to do with the classic
/historic halide versus halide-free debate. It's now more an environmental
issue. 
Simplistically/succinctly: some halides are bad environmentally, therefore
all halides are bad. This because telling the difference is hard, finding
them is not. So whether the halides in your product are bad or not is no
longer relevant, it's just too hard to explain to whoever that there are
'bad halides' and 'it doesn't matter halides' and they may not be listening
anyway so..... a no halides policy solves the problem.

Be aware it can be more difficult to make halide free fluxes as effective as
halide containing, and certainly wetting on different surfaces can be
different, so you might experience some change in performance or wash off.

Subject: [TN] halides in water soluble fluxes

We have some parts that are sensitive to halides in flux, specifically some
thru-hole opto devices.  We are currently using a water soluble flux that
contains halides.  In doing some very quick research it looks like the WS
fluxes have halides and the NC fluxes do not.

Is there a halide free WS flux for lead-free wave soldering (foam
application)?

We need the WS fluxes because we currently use a DI water only batch wash
system.  Washing the boards is mandatory for our applications.

Thanks in advance,
