Hi Jan - there are lots of pros and cons with the use of water soluable fluxes. Your use environment, pwa configuration, and type of cleaning system play important roles in whether you create fuzzy assemblies or nonfuzzy assemblies. Give Doug Pauls ([log in to unmask]) an email for additional info.

The company I have recently hired on at, would like to immediately change over from RMA flux to Water Soluble flux for both SMT and thru-hole. Most of our work is military. It has been several years since I've researched this topic. Are SIR tests still required to prove your cleaning methods? Are SIR tests only required for government contracts? Can Water Soluble fluxes be used on stranded wire? Which is a better cleaning process for Water Soluble flux, Batch systems or in-line systems? Have most government contractors switched to WS Flux or still using RMA? Thanks in advance for all responses.
