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

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

Another equipment manufacturer is Smart Sonic. Most equipment manufacturers have their own chemistries, but they are also willing to use other cleaners. What we have done is to send boards that need to be cleaned to the equipment manufacturer. W

If you do not have any luck finding a west coast lab, but need services I am sure we can help. The only problem is we are on the east coast. Many moons ago empf was on the west coast (China Lake) but moved eastward. We are in Philadelphia, PA. (ski

I hope I'm not too late with some help for you. I have purchased stainless steel wire cleaning baskets for a vapor degreaser from: Cooley Wire Products 5025 North River Road Schiller Park, IL 60176 847-678-8585 fax 847-678-8612 They do a very nice

CAL, Thanks for the input. When I said chemistry I was refering to soldering chemistry and not cleaning. I believe this machine has the capability to incorporate a saponifier but would prefer not to run in this manner. Running a closed loop DI re
