How do you guys clean whole pcb boards?

Postby camo » Wed Aug 26, 2015 9:53 pm

I know most that have the money probably have a nice heated ultrasonic cleaner to clean pcb boards. Lets say one couldn't afford a ulltrasonic cleaner. What would be a good yet cheap option?
I heard of people using household steamers with a 60/40 90%ISO or higher/Distilled water mix or just distlled water.without any trouble, probably just have to wait a long time(5hrs+) to make sure all moisture fully evaporates . Could probably heat the board some to speed it up.

Wouldn't use a steamer on smd pcbs.
It could blow of working but badly soldered components.

Ultrasonic cleaner with the correct solution is the proper way. Any other method is a hack!

And steam cleaner! :facepalm:

Just the sheer notion of it MAKES MONGO MAD!!! :evil:

Like VaNDAL_UK says: US cleaner "with the correct solution".

For e.g. flux cleaning, IPA99% is not allways the correct solution for flux cleaning.
With manual cleaning like rubbing with IPA it looks fine, but that can be more due the rubbing instead of the IPA attacking the residue.
IPA is part of most flux cleaners, but the active part for the flux is mostly something else.

IPA should never be used in a US cleaner, surely not the ones getting warm.
Yes, I know, you read about people using IPA in their US cleaners without problems.
But if you're the one with the bad karma...
Ignitionpoint is over 400c, but flashpoint is at 12c allready, 1 spark is enough.

I use also a ultra soon cleaner. with 10% Tickopur solution. on 65C temp and 3 minutes. This works for me very good.
Have a cleaner with 15 liter capacity.

Dish soap + IPA 91% (1 cup per 10L) + Water in ultrasonic cleaer at 60c for about 25 min does the trick for me. Make sure the water is at the right temp though, warmer makes the flux easier to remove.

Spot cleaning I use Q-Tips and Acetone
