Dish washer for cleaning PCB's with BGA's
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 not capable of applying saponifier or surfactant.
