Short of buying a closed look wash system, what other machines/processes are available for localized removal of flux that is not operator intensive. already familiar with Branson ultrasonics and just washing in alcohol but what else is out there?

I recently saw a brief presentation on selective cleaning using Co2. In basic terms a fine jet of Co2 is blasted onto the desired area of the PCB removing the contamination and supposedly causing no damage to PCB or components. I think it's quite a n

The water soluble flux residue is staying there because the rinsing temperature it may be too low. The flux needs about 130-140 degrees celcius to become soft. If you are using water soluble flux, as per IPC A 610 standards it needs to be remove comp

Because our boards are heavily heatsinked with dow 340 which never hardens and I am afraid I will not only wash off the flux but the heatsink compound as well.

Mike, I totally understand your position. We find ourselves in two opposite camps. If no-residue was impossible my company would not be in business today. Lets focus on the topics so we can help people with their problems. Patrick

Hi esoderberg - I was wondering if you had tried altering your soldering profile to try and fully solublize the no clean flux residues and elimate your cleaning dilemma? You can check out my company's website if you want some free reference material

A PCBA contains a couple of parts that are not sealed and can't be water washed. We hand solder these with no-clean after everything else is water washed. The designer says the no-clean residue must be completely removed so that it will not affect
