We use Kester 2120 WS halide free flux both as spray and foam application in our wave (tin-lead assembly). It can be thinned with IPA for foam application. We started using this flux about 6 years ago for the same reason for a medical customer of ours. This flux has been easy to clean in our application with straight DI in-line wash (135 F)

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,
