Hi Guys, Have you tried using a standard dish washer for cleaning PCB's with BGA's. What detergent or cleaning chemicals did you used? I wonder if it will work to clean a WS Flux PCB using the dish washer then get it rinsed by an old aqueou cleaner

We are manufacturing an NPI board for a Customer and they want us to wash the board using a Saponifier wash. However, one of the SMT parts cannot be placed through a wash process. Has anyone ever had to encapsulate a component to prevent water da

Have you considered mounting this component after the assembly has been washed. Then, mounting the component and cleaning its solder joints individually. Alternatively, have you considered using alternative cleaning solutions to a saponifier (and a

Whatever you do, don't get a cleaner where they "lock" you into using their Saponifier! I remember at my previous company, getting that monstrosity running was my 1st project - the boob who bought it washed his hands of it and assigned it to me.....

Wash them in Saponifier frequently at around 40C rinse and dry thoroughly. I would imagine it could be going white if you have a resin system in the flux that is not water soluble. Ensure you are using suitable pallet material up to 300C for Lead Fre

What process / equipment have you found to best mark Revision levels / date codes and such onto small areas on PC Boards? I need a repeatable, economic solution that will endure processing temps and saponifier in the cleaners. Have used RoHS co

The blue tint could be the result of etching of the tin in your solder connection during cleaning when using a slightly basic cleaning solution. Just about anyone can duplicate this by running a board 7 or 8 times through a cleaner with a saponified

We had a similar problem with foam in our inline cleaner (TD). The problem were the solder paste flux residues. Boards went straight from SMT to Wave process and then washed. Anyway we changed the solder paste and problem solved. Are you using saponi

We have used it,, mixed results, cleans well, but can as you would imagine destroy plastic, i've had operators soak product and that caused problems, it also destroys any marking labels. we also use different Saponifiers to remove residues in the pas

I know you mentioned you use a Tech Spray product. We have had success with their "Wondermask" water soluble product. When using a chemical additive (saponifier) in an aqueous cleaning system we have not experienced residues. I hope that helps. https
