Thanks to all for your quick and helpful replies. Doug/Ken Your right it should have been OA Phil Belliveau Ken Patel <[log in to unmask] To: [log in to unmask] OM> cc: Sent by: Subject: Re: [TN] Flux Controls TechNet <[log in to unmask] ORG> 12/14/01 05:08 PM Please respond to "TechNet E-Mail Forum." I think there is a typo. QA should be OA (Organic Acids) based flux, very strong. Need very good control in storage and while using on the board. If left on the board, it will eat away the boards slowly. Color coding is the best option. Don't allow flux chemistry to get mixed. People will love OA flux and you may find some operators want to use OA instead of RMA as OA flux allows fast wetting because of the better cleaning of the surface. Thorough cleaning should be mandatory preferably in the washer than using a DI water & a brush. re, Ken Patel [log in to unmask] wrote: > Hello Technetters > > I need help.
