Should drying be done after aqueous wash? If so, how long and at what temperature?

It depends on the water quality of your final rinse too. Too dirty and pools of water will trap residues on your board. If let to evaporate, these residues can stay on your board.

The cleaner does have a dryer, but does not remove all moisture - we can see that. It is functioning - we can see that too.

So what are your current drying parameters? can you adjust temp and time? is this a batch cleaner that may have some shadowing from the way it is loaded causing hot air to not hit certain boards? Russ

Well i guess you would not have to dry the boards but let me ask this, Are you hand cleaning water soluble flux in a sink? Never seen a cleaner without a dryer. Anyway temp and time for drying is easy to figure out. When boards are dry you have i

Look for the following machines: Aqueous Technologies ECD EMC Austin American The above mfrs. make "industrial" grade dishwashers for assembled PCB de-fluxing. Search any of those names followed by "..... batch cleaner", and your search engine will

Is there a peelable solder mask which can withstand an automated aqueous wash ? I need to prevent water ingress into SMT modules during the wash cycle.

we received assembled PCBs with spots that look like a bleach spots all over the PS and CS . The board house said that this is normal due to flux aqueous wash process. Can it cause problems (e.g. corrosion ) in the long run or cause issues when wor

Solder mask is intended to protect the traces from the soldering process. That's it. [Tried to upload a picture. It's broken.]
