Is there any field proven spray cleaning technique able to remove flux residues under OSRAM LEDs? Is it possible in principle? The problem is that OSRAM LEDs are low standoff ones and I absolutely have no idea how cleaning agent could get there. Mo

esoderberg: So, why do you want to clean your no-clean flux residues?

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?

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.

Regarding the reference (Patrick) to a previous thread promoting �no-residue� fluxes, I must say that there is absolutely no such thing as �No-Residue� flux. There are �Low-Residue� fluxes and even �Very-Low� residue fluxes but to suggest that 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

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

Just curious� Why only localized cleaning? Why not clean the entire board? Localized cleaning by nature is labor intensive. Mike Konrad Aqueous Technologies (909) 944-7771 ext 29 www.aqueoustech.com konrad@aqueoustech.com

I agree with dave here's an example of a previous thread on the subject. http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=6947&#Top

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
