Using a vapor degreaser with a solvent such as Vertrel, Novec, Techspray 1655, Solstice, etc. may work for you but solvents can attack certain plastics. Should be fine for SMT though. This is assuming you are using a no-clean (RMA) type flux, not wat

I would question your motive "There's no way that I feel comfortable shipping boards after a selective without cleaning them, the amount of flux on the board is significantly more than from SMT". 1. Who said that residue should be cleaned and why? O

We roll ours up, fingers and all, and soak them for about an hour in a solution of water and DOMINATE (heavy duty degreaser) you can order from Grainger. They come out looking brand new every time!

Welcome!!! Where the hay ya been??? Sorry bud, were lining-up with your fab [it hurts me to say that, but when yer ] We used to dry pack with desiccants, also. Its probably an old MIL-STD-2073-1C requirement [er something like that]. We qui

I said: "Our electronic circuit board fabricators seal the boards in moisture barrier bags [MBB]. We discontinued the use of desiccant bags in these MBB because of concerns about the desiccant releasing materials that would affect the solderability

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq

Mike: It gets more humid in the winter? [I can see it�s true (not that I�d doubt you) cause I�m looking a a humidy map of the USA, right now] How does that work outin Californy? [Do the ocean breezes move the humid air in-land in the summer? Er w
